Welcome To Cooling Season: What You Need to do to Prep Your AC for a Busy August

The days are longer, people around the office are taking vacations, and the temperature is constantly hitting the nineties. There’s no question about it: the dog days of summer are at our doorstep. And with the hottest weeks of the year ahead of us, it’s important to make sure your AC is up to the challenge. In order to make absolutely sure you’re set up for success this August, there are a few easy, DIY maintenance tasks you can carry out on your own at home.  If you need air conditioner repair, this is the way to find out. 

Safety is Key

Before you do anything for your system, you want to make sure that you keep yourself safe while you work. If you have an outdoor unit, you need to deactivate the power before doing ANYTHING. A fully-powered AC unit can be incredibly hazardous with spinning fans, live electricity and the like. Before doing anything related to prepping your AC, be sure to disconnect the power before doing anything. You can’t enjoy your summer from a hospital room.

Out With The Old, In With The New 

You don’t need to be an HVAC tech to understand that a dirty air filter means you’re going to have dirty air. After a long winter hibernation (and probably a summer of heavy use from last year), your air filters are going to be worn down, dirty, and minimally effective. Air filters are cheap, easy to find, and relatively easy to replace if you have a general idea of what you’re doing. Air filters are one of the first things to go after the winter and as such are one of the first things you should be replacing when the summer rolls around. 

 Consider Completely Cleaning Condenser Coils

Over the winter months, your condenser unit will accrue some debris: dirt, leaves, water, etc. Again, you don’t need to be an expert to know that such debris is not conducive to your AC’s performance. The condenser coil is one of the most important parts of your unit, which itself is the large metal box outside your house that has spinning fans. If the condenser was covered during the winter, there probably won’t be a massive amount of debris on it in the summer. If you didn’t cover it, consider doing so this fall. 

Make sure the fan is clear of any and all refuse. Next you need to open the box and check the coils. If there is anything on these coils, there’s a very particular set of things you need to do to make sure the system runs at peak efficiency

  • Remove the side and top panels or protective grilles from the condenser unit. Note: Double check to make certain the power to the condenser unit is turned off.
  • Lift off the top. The fan may be attached to it making it heavy. Note: Don’t tug any of the wires connected to the fan.
  • Using a refrigerator coil brush or a soft brush on a vacuum, gently clean the coils from the outside of the unit. After you clean the outside, vacuum coils from the inside. Note: Be careful not to bend the delicate fins or damage the coils

Check the Coolant Lines

The coolant lines essentially are what carries the cool air to your home from the condenser unit. If these lines are damaged in any way there’s no guarantee regarding the efficiency. These lines are usually covered with some kind of insulation to prevent the cool air from escaping the tubes before it gets into your home. You’re going to want to check this insulation thoroughly to see if any portion of it is compromised: any fraying or wearing needs to be addressed now because it’ll only get worse over time. 

Testing 1 2 3…

The final step of any start of season AC tune-up is to test out your system. Because at the end of the day, there are still plenty of things that could go wrong with your AC that you wouldn’t really have a way of knowing the damage of. A quick test run of your system for about an hour will be able to determine any nascent with you wouldn’t be able to determine at baseline.

Know When to Call in Backup

We love to see homeowners embrace the DIY spirit. IT shows initiative and genuine investment in their home’s HVAC system. That said, there are some things best left to professionals.

5 Warning Signs of an Impending AC Failure

5 Warning Signs of an Impending AC Failure

  • Cooling
AC failure

The last thing you want to hear on a hot summer’s day is the sputtering death rattle of an AC failure. Since that is something of a worst case scenario, you obviously want to avoid it. Thankfully, it’s rare for a system to just up and die out of absolutely nowhere; there are normally some easy to identify warning signs that the astute homeowner can hone in on and fix before they become full-fledged system killing issues. Here are a few of the more major things that’ll warn you of an AC failure in your future. 

Your AC is Blowing Hot Air or No Air at All

The whole purpose of your air conditioner is to deliver cool, temperate air into your home. Obviously if that is not happening there’s a red flag going off. It’s likely this could be the result of a bad capacitor, a filter clog, or depleted refrigerant. As much as we value the DIY spirit, these are issues best left to the pros. If you notice warm air when your AC is running, call a North Shore team member and we’ll get it sorted out.

You’re Getting Weird Smells Through Your Vents

You can probably count on one hand the situations where you want to smell a burning smell; “from your AC system” is not one of them. If you notice a smell like that, you’ve almost definitely got a fried wire, which is an increased risk of an electrical fire. But as long as we’re talking about the smells that come from ACs, equally as common as the burning smell is an oppressive, musty, and dank smell. Usually this is indicative of biological growth in your vents like mold and the like. This is a little less serious than an impending electrical fire, but obviously still requires your immediate attention. If something smells fishy, something is fishy.

Loud Clanging Noises Coming From Your Indoor Unit 

No matter what type of system you have, you should never hear it from the inside of your home.  Any scraping, clanging, or squealing should be like blaring warning sirens to you that something is not operating as intended in your system. These sounds are often due to something falling out of place or just needing some extra lubrication. Of all the issues your AC may be facing, you want to act on these most quickly. Issues like these could quickly escalate from a quick fix to a massively costly repair, if not the total death of your system. 

You’re Getting Higher Utility Bills 

When a system is on its last legs, the #1 most common trait is a reduced efficiency of the system. Reduced efficiency means lower output for the same amount of time, which ultimately translates for high bills for less actual cooling. This can be due to any number of issues too numerous to list in an article like this, but it is always a sign that a professional touch is necessary to get your cooling efforts back under control. Nobody likes higher bills and in this economy you want to be saving as much money as you possibly can. 

Moisture In and Around Your Unit 

When is a leak ever a good sign of anything? Pretty much never, and the same goes for your air conditioner. When you go outside and notice moisture and water around the base of your condenser unit, that’s a pretty airtight way to find out that something is not right.

5 Fast, Easy Tips For Ductless AC Maintenance

5 Fast, Easy Tips For Ductless AC Maintenance

  • Cooling
ductless AC maintenance

A ductless AC is extremely handy for homeowners looking for a more focused cooling effort in their home. Whether it’s a home office, a living room, bedroom, ductless ACs are fantastic for cooling the most-used areas of your abode with minimal costs to your overall energy bill. With some proper maintenance and TLC, your ductless AC can and will serve you well for years on end. But you need to know how to take care of it.

Keep the Exterior Unit Clean

As you’re probably aware, your ductless unit is comprised of the interior unit responsible for blowing the cool air into your home and the exterior unit where the air comes from. As it’s outside, the latter component is exposed to the elements on a regular basis. Rain, snow, sleet, animals, you name it your outdoor unit has to deal with it. An occasional sweeping of it, clearing it of debris, dust, and accumulated dirt. While you may not think so, keeping the exterior unit clean saves you and HVAC techs a huge amount of headache later on when you need more in-depth service.

Check the Filters

Filters prevent harmful, nasty particles from flowing through your HVAC systems. Things like dust, pet dander and even bacteria and viruses get caught in the filter and stop circulating in your home. That’s only if you have a functioning filter, however. Old filters get clogged up with gunk and refuse over time and stop working, allowing all manner of particles to float through your home.  Thankfully, replacing your filters is a pretty easy process you can do with even a small amount of HVAC know-how. Depending on your unit, you may even be able to clean the filter you have with a dry cloth. The intrepid homeowner is going to want to check their air filters every month and a half or so.

Clear the Area Around the Interior Unit

While not nearly as bulky as other varieties of air conditioner, ductless ACs need some room to breathe.  The interior unit needs a good amount of wall space to operate to the best of its ability. About four feet in every direction (aside from the wall itself) should be sufficient space to ensure optimal cooling. Make sure things like book cases, wall-mounted televisions, sofas, and framed photos are well out of the way from your AC to ensure nothing goes awry.

A Clean Condenser is a Functional Condenser

You may think internal cleaning is beyond what you’re capable of as a homeowner. So long as you know what you’re doing and are safe, personal cleaning of your ductless unit can be an extremely beneficial way to increase its lifespan and make it run smoother longer. Before you do anything, make sure the unit is completely powered down to avoid damaging components, or worse, injuring yourself. Once the condenser is powered down, you can use your garden hose (at low pressure) to clean off any accumulated dirt and debris from the unit. If left unchecked, this can clog up your fans and impede your AC’s ability to function properly. Once the water is dry, make sure the fins did not bend (they can be realigned with a simple alignment comb) and dust off any remaining matter by hand.

Call a Professional For a Regular Tune-up

We here at North Shore are all for the DIY spirit. But some things do require a professional touch. Calling out an HVAC tech every once in a while for a regularly scheduled inspection will help identify and isolate issues as they appear and before they snowball out of control. A visit from your friendly neighborhood HVAC professional every so often can save you a lot of money and headache down the line.

10 Solutions for Air Leak Repair

10 Solutions for Air Leak Repair

  • Cooling
air leak repair

You wouldn’t run the heat in the house with the windows open in the winter, would you? Of course not! Unfortunately, when you have multiple air leaks in the house, this is the exact effect happening within your home. The warm, expensive indoor air is permitted to escape the house, while chilly, winter outdoor air is allowed into the home. These air leaks can be found in many areas of the home. The attic, windows, doors, and basement are prime places for the average homeowner to lose warm air to the outdoors. You need air leak repair and you need it fast. 

]If the weather in your area is beginning to get a little chilly, you may want to begin some yearly maintenance tasks to keep the cold air out of your home. If the warm air leaks outdoors, your heating unit will have to work overtime to try to keep the house comfortable. This means more wear and tear on your unit, and possibly costly repairs in the future. Additionally, you will feel chillier in the house and your heating bills will skyrocket if too much cold air is able to penetrate your home. Most of the following ten repairs are fairly inexpensive and simple to do, requiring little more than a screwdriver, a few easily found items, and a sharp pair of eyes. If you can’t afford the big tasks, like new windows or a complete insulation replacement in the attic, do what you can in other areas of the house. Tackle a few of these jobs each weekend, and you’ll be surprised at how much cozier your home is this winter.

1. Caulk and weatherstrip doors and windows that leak air.

You know what it’s like to stand in front of the door with cold air blowing on your toes from the crack under the door. Seal those door jambs and thresholds with weatherstripping. Also, pass your hand around the window frames and door frames. If you feel cool air, caulk the cracks to keep out the air

2. Install foam gaskets behind outlets and switch plates on the wall.

This is super easy to do, but it does take a little bit of time.  For just a few dollars, you can buy a large packet of foam gaskets to insulate behind your light switches and electrical outlets. Simply remove the center screw that holds in the faceplate, place the foam gasket in place, and replace the faceplate and screw. 

3. Install foam sealants on larger gaps on windows.

If you have larger cracks and gaps in the framing around your windows and doors, you may be better off using expanding foam to seal them up. Use this stuff carefully and always wear gloves while applying it.

4. Inspect insulation for mold and leaks.

When checking out the neglected corners of your house for air leaks, pay attention to the status of your insulation. If you have moldy insulation, you should replace it. Mold can make people very sick, and it’s an indication of dampness that can lead to rotten wood. Make sure there are no gaps or leaks in your insulation .

5. Cover or replace single-pane windows. If you seek replacement, install efficient double-pane windows instead.

While it can be expensive to replace the windows in your home, installing efficient double paned windows can save you big money over the years and keep your home more comfortable. The air space between double paned windows serves as insulation to allow light in, but keep cold air outside. If you can’t afford new windows at this time, using a window insulation kit or heavy insulated drapes can help keep winter drafts at bay.

6. Cover the kitchen exhaust fan when you are not using it.

The kitchen exhaust is like a huge chimney and can vent your indoor air if you don’t pay attention to it. You can cover this opening with a dishtowel using Velcro type attachments. However, it is very important to not forget to remove it before you turn on the fan. Also, don’t make the mistake of shoving an old rag in the opening. If someone doesn’t know about it or forgets to remove it before turning on the fan, the rag can be sucked up into the exhaust fan, completely ruining the appliance.

7. Seal air leaks around furnaces, chimneys, or water heater vents with fire resistant materials.

Be sure that when you insulate and seal around potential fire hazards that you use fire retardant materials. Places like chimneys, furnaces, and hot water heater vents can get very hot. Flammable materials could ignite in these places.

8. Check your dryer vent for any blockage.

While you’re checking around the dryer vent, you may want to make a quick inspection of the dryer vent. If the dryer vent is blocked this is a fire risk.. Also, your dryer will be very inefficient without maximum airflow.

9. Check attics, basements, and crawl spaces for air leaks before the winter begins.

Look around in the frequently overlooked areas of the home for cold air leaks. Attics, basements, and crawl spaces can be places where cool air can enter the home. Close the vents to crawl spaces to keep cool air out. Shine a flashlight in dim corners to ensure that rodents or other critters haven’t chewed holes in unexpected places. Seal up cracks with putty or caulk, and make sure the insulation in the attic hasn’t been disturbed.

10. Seal air leaks around any plumbing or electrical fixtures coming from the walls, floor, and ceiling. 

Any time an electrical or plumbing fixture enters the house, there’s a chance that the opening through the wall isn’t sealed well. Double check these areas, and use foam insulation or caulk to close up holes where cold air can invade. Look behind toilets, under sinks, where the refrigerator water line enters the house, and where the dryer vent exhausts to the outdoors.

A Comprehensive Guide to Duct Cleaning

May 01, 2022

A Comprehensive Guide to Duct Cleaning

  • Cooling
  • Heating
duct cleaning

Does your home have an HVAC system? Then it’s important to perform regular duct cleaning to ensure the air flow into your home is as clean as possible. The system’s vents will get dusty over time, since dust particles are naturally drawn into the duct along with the air. By cleaning them thoroughly, you can reduce the amount of unwanted particulate in your household’s airflow. In addition, by keeping your air ducts clean, your HVAC system will be more energy-efficient, which will prevent your energy bills from rising. 

How to clean your air ducts yourself

Fortunately, you can do routine duct cleaning yourself. You’ll need a Phillips screwdriver; household cleaner; a cloth; warm, soapy water (optional); microfiber cleaning cloths; and a vacuum cleaner (preferably one with a HEPA filter) with a dust brush. You’ll also need protective eyeglasses, a face mask, and sturdy rubber gloves.

  • Turn off your HVAC system. Before starting, turn off your HVAC system. The last thing you want is for air to be blowing onto you while you’re trying to remove dust and debris from the vent. 
  • Remove the vent cover. Wall vent covers need to be unscrewed. Do this carefully to avoid damaging the wall. Some floor vents can simply be lifted up, while others also need to be unscrewed. 
  • Clean the vent cover. There’s likely dust caught in the vent cover; plus, it will feel greasy to the touch. You can clean it with a regular household cleaner and a cloth, or you can wash it in warm water and dish detergent. Always make sure to dry it carefully. 
  • If you have vent register filters, clean them. Some vents have filters installed to catch pet hairs or other things. If your vents have filters, remove the debris that’s built up, and clean them.
  • Vacuum the inside of the vent. Attach the dust brush to the vacuum cleaner and reach as far as you can inside the vent. Vacuum up all visible dust and debris.
  • Wipe the inside of the vent. Using a microfiber cleaning cloth and the household cleaner, wipe the inside of the vent as far as you can reach. 
  • Re-attach the vent cover. Carefully replace the vent cover. If it’s attached with screws, make sure they’re firmly screwed in place. 
  • Clean your HVAC system’s filter. To get the best performance from your HVAC and ensure the best indoor air quality, clean or replace your HVAC’s filter when you’ve finished cleaning your vents. 

Note that if you find any signs of mold infestations, pests, or damage to the inside of the ducts, you’re best advised to call your HVAC expert right away as these are issues you shouldn’t address yourself. 

Why you should still schedule professional duct cleaning

Keep in mind that it’s always a good idea to schedule professional duct cleaning and maintenance at least once a year. That way, your HVAC specialist can remove all dust and debris you might not be able to reach and at the same time, repair any damage that might be causing air leaks. And in the long run, whatever time, effort, and money you spend on duct cleaning is an investment in better indoor air quality—and that’s better for your and your family’s health.

4 Signs That A Ductless Mini-Split AC May Be Right For You

Jul 21, 2021

4 Signs That A Ductless Mini-Split AC May Be Right For You

  • Cooling
ductless mini-split

There are a lot of options out there for cooling systems. You have the standard central air systems, evaporative coolers, and even the classic window units. And that’s just scratching the surface of the deep, deep rabbit hole that is the air conditioner market. An often-overlooked variety is the ductless mini-split, which shares qualities of the other more traditional systems.  They are similar to central air systems in their shared indoor air-handling unit as well as an outdoor compressor/condenser. The conduit links the two parts of the system together and contains the refrigerant tubing, power cables, condensate drain and suction tubing. Ductless mini-splits are an increasingly popular choice amongst homeowners in the North Shore area, so we’ve complied a short list of signs that you may want to look at a ductless mini-split.

Your Energy Bill is too High

Money makes the world go round, and there are certainly some financial incentives to adopting a ductless system. Ducted systems, while they have their benefits, aren’t always the most efficient option. With a ductless mini-split, energy loss is generally less than with a ducted system, where losses can be up to 30%. Saving that much on energy costs is nothing to joke about, and will eventually result in a net gain on you finances. Granted, the system does require more regular maintenance than the standard central air system, which mainly consists of a monthly filter care to maintain air quality. But when boiled down to a choice between a higher energy bill or a little more time on maintenance, most folks should be able to make up their minds.

Your Space is not Duct-Friendly

Some spaces are just not constructed in such a way that makes duct work financially realistic. In some cases, especially in certain older buildings, installing ducts may even be impossible.  For those older structures, mobile homes, and newly constructed home additions, a ductless mini-split solution is your best bet for maximum comfort. While we’re on the topic of space, we’d be remiss if we didn’t mention how space-friendly ductless mini-split systems are. They can be mounted in any number of ways, including, but not limited to, flush-mounted on the ceiling, hung from the wall or suspended from the ceiling. The sleekly designed Mitsubishi Electric model, in particular, fits in subtly in any environment, and can be unobtrusively installed most anywhere that suits your needs.

You Need to Closely Control the Temperature in a Smaller Area

Ductless mini-split systems are at their strongest when used within a compact space. Depending on need, you may require multiple units to cover a greater area. Alternatively, you may elect to only cool certain high-traffic areas of the home.  Mini-splits offer a great deal of customization and control on the user-end, and can even be programmed to only turn on when the building is occupied, or on a schedule.

You want a system that runs cleaner

You don’t need to be one of our expertly-trained HVAC techs to know: sometimes air ducts can get downright filthy. Air ducts are notorious for being one of the primary areas for a buildup of dust, dirt, pollen, and other contaminants which may be harmful to your health. Ducts require frequent cleaning to maintain interior air quality and ensure occupant safety.  Eschewing ducts altogether, a mini-split denies these harmful materials an easy place to buildup and accumulate over time and also eliminates the need to frequent professional cleanings.

Air Conditioners: What You Need to Know For This Cooling Season

Apr 19, 2021

Air Conditioners: What You Need to Know For This Cooling Season

  • Cooling
air conditioners

Air conditioners just blow cold air into your home, right? Actually, no. Cooling the air in your home is accomplished through a relatively complicated process that involves refrigerant fluid that shuttles heat back and forth between an outside compressor as it transforms from a liquid to a gas and back again. It takes quite a bit of electricity to perform this modern magic show of moving heat from a cooler place and back to a warmer place.

Types of Air Conditioning Systems

There are several different technology options involved with the process of cooling your home: central air conditioners and heat pumps, evaporative coolers, room air conditioners and ductless mini-split air conditioners. 

  • Central air conditioners and heat pumps are the most common form of systems, and unlike some of the other options they are often used to heat entire homes. They generally consist of a large compressor that is external to the home and drives the process and indoor refrigerant coils that distribute cool air throughout the home via ducts. Heat pumps work similarly, except they are also able to distribute warm air in the cooler winter months. Ducts throughout the home are utilized for distribution of both warm and cool air in concert with a fan system. 
  • Room air conditioners are mounted either on the walls, ceiling or through a window. These systems work in a similar fashion to central air conditioners, but compressors are located outside the home and the systems are generally built to control the temperature in a single room. These units are less expensive to purchase, but are potentially less efficient and have a higher daily running cost overall. 
  • Evaporative coolers, also known as swamp coolers, can be a practical alternative in certain parts of the country but are much less common than central air or room air conditioners. These unique systems operate by pulling fresh air through an evaporative system that involves moist pads and a whole-house circulation mechanism. While swamp coolers are only efficient in the drier areas of the country, they are very efficient and cost-effective to run and can reduce the temperature of your home by up to 30 degrees. The cost of purchase and installation is also lower as these systems are relatively simplistic. Evaporative coolers work most effectively in dry climates because the system works by putting moisture back into the air — something that isn’t as efficient in a wet climate. 
  • Ductless mini-split air conditioners are more popular outside the U.S., but are gaining prominence with homeowners who are updating a portion of their home or reworking an older addition that doesn’t have ductwork in place. They are similar to room air conditioners in that they are a zoned system, but the functionality is more similar to a conventional central air conditioning unit. When you’re using a ductless system, you also avoid the energy loss that is associated with a traditional system with ducts. You can also maintain overall cleaner air due to the lack of cracks and crevices in the ducts for dust, mold and other contaminants to hide.
  • New technology options include the Night Breeze, which integrates a whole-house fan, indirect water heater and air conditioner in one unit as well as Thermal Energy Storage where energy is stored overnight in ice — ideal for climates where energy costs are high during peak usage times. 

Warning Signs

Other than the obvious (it’s getting hot in here!) signs, there are multiple ways to determine that your system either needs maintenance or replacement. However, if you’re not as experienced with home maintenance and air conditioners, you may wonder if the problem is in your head or if it truly exists. Since air conditioners are used most heavily during the summer months, it’s important to get a tune-up before the heat of summer really kicks in. Qualified and licensed professionals perform a full system inspection to catch some standard problems that can occur. A check up generally includes:

  • Performance test of the full system
  • Visual review of all air conditioner components
  • Tests to determine the state of the refrigerant charge and overall system control testing
  • The use of an approved leak detector to perform a leak test
  • If slow leaks are suspected, your professional may perform a dye detection test

How can you tell that your system is not functioning as it should? Here’s a few things to look out for:

  • Air is not flowing as easily as it should be. If you’re seeing poor air flow through your vents, it’s probably time to call a professional. 
  • Zone issues — where part of your home is comfortable and another part is too hot or cool — are a good sign that there may be something wrong with your thermostat.
  • Excess moisture where it doesn’t belong can also be an indicator that it’s time to call a professional. 
  • Foul odors coming from your air conditioning unit are never a good sign. Mold can grow in wet, dark spaces and an air conditioning unit certainly fits those parameters.
  • Squeaking or squealing sounds coming from your air conditioning unit may indicate that a belt has slipped. This generally requires professional assistance to resolve.
  • Of course, if you find that your home is heating up unexpectedly, or the air conditioner is cycling (turning on and off quickly), you should have your unit checked out. 

With careful use and a solid maintenance schedule, nearly all types of air conditioning units will last upwards of 15 to 20 years. Your system should receive maintenance at least once a year in the spring, before it’s heavily used in the summer heat. This ensures that you’re catching any small problems such as leaks quickly and before they have a large impact on the functioning of your system. The cost of not performing regular maintenance could be decreased system efficiency or even having a system that freezes up or sustains serious damage from broken items such as motor bearings.

Local Ductless Mini Split Installation

If you have a radiant heating system, space heaters or hydronic heat, a ductless mini-split installation might be a good option to add heating & cooling to your home. They are also a good choice when you’re adding rooms to a home that doesn’t have a traditional ducted system, or for spaces that are very energy efficient and only need a small boost. Ductless mini-split systems are similar to standard heat pumps as they have an indoor air-handling unit as well as an outdoor compressor/condenser. The conduit links the two parts of the system together and contains the refrigerant tubing, power cables, condensate drain and suction tubing.

Advantages & Benefits

Ductless systems work well in spaces that are considered too tight for ductwork, or when you need to heat or cool a relatively small space. The specific number of units that you’ll need depends a great deal on the zone that each unit will cover — all dependent on the overall insulation rating of the building. These systems are relatively easy to install as they only require a very small hole (around 3 inches) to run the conduit. Even more convenience is gained because there can be a significant distance between the interior unit and the external condenser, up to 50 feet or more depending on the length of conduits available for your particular system. This allows you to place the unsightly exterior pieces further away from your home or apartment for aesthetic reasons. 

Additional benefits:

  • Energy loss is generally less than with a ducted system, where losses can be up to 30%
  • More flexible options for mounting ductless systems: flush-mounted on the ceiling, hung from the wall, or suspended from the ceiling
  • Are more sleek looking than traditional systems, and often come with a remote control for added convenience
  • Window-mounted units may induce intruders and are less secure than ductless systems, as mini-splits only require a small 3 inch hole in the wall
  • Potential energy savings because the units are more cost-effective and efficient to run
  • Highly customizable: can be programmed to only turn on when the building is occupied, or on a timed schedule
  • Ductless systems run cleaner than a ducted system. Air ducts are one of the primary areas for a buildup of dust, dirt, pollen and other contaminants and require frequent cleaning to maintain interior air quality 

Challenges to Going Ductless

While there are many benefits for using a mini-split system in the right space, there are some disadvantages as well. There is a fair amount of maintenance required such as a monthly washing of filters to maintain air quality and system efficiency. If you inherit an older system that hasn’t been well maintained and it requires professional cleaning, then the cost can be quite high. The installation cost of a mini-split can be higher than a traditional system, but this is balanced by an ongoing lower cost for energy due to efficiency. However, ductless systems often net homeowners a rebate because the systems are so environmentally friendly. Improperly placed systems can cause serious problems — from hot and cold spots throughout your space to inefficiency due to short-cycling. It’s important to always utilize a licensed and bonded HVAC professional when you’re considering a ductless mini-split heat pump. Finally, the outdoor condenser requires a nearby drain location, which can cause ongoing problems if space is a factor.

Successful Ductless Mini-Split Installation

As ductless mini-split systems gain in prominence, more contractors and technicians are comfortable with their installation. However, it’s still important to keep some key factors in mind to ensure that your installation goes smoothly and you continue to enjoy your space comfortably. Here’s some quick tips for successful installation:

  • Wire power supplies directly from the indoor unit to the outdoor unit, without a junction box or disconnect switch between the two
  • Control the voltage — only use the correct gauge wire for your installation 
  • Ensure that units are hung a minimum of six feet in the air for maximum efficiency
  • Limit obstacles in the area that might impede or reduce air flow
  • Check and double-check that the unit is rated for the room size
  • Insulate both the liquid and suction lines to prevent lines from ‘sweating’

Warning Signs

Even the most secure installations can run into problems, and ductless mini-splits are no different from traditional ducted systems in this regard. If you experience instances where there’s cold air coming through your heating vents, it’s time to call a professional. While the resolution may be quite simple, this can also be a harbinger of a more serious issue and should be resolved. If your system is short-cycling — or running for only a short period of time before turning off and then running again — you may be facing a problem. Short-cycling drives up your energy costs and puts a great deal of strain on the system overall, which can result in expensive problems in a very short period of time. Finally, if your energy costs are going up and there doesn’t appear to be a corresponding change in external temperatures, you might be having problems that require professional assistance.

Life Expectancy of A Ductless Mini-Split Installation

With proper cleaning and maintenance, your ductless mini-split heat pump system should last between 12 – 15 years. As long as you keep debris, vegetation, and snow away from your external unit (and keep your compressor relatively clean) you should have no problem extending the life of your unit. It’s also important to keep in mind that these systems work best between 14 degrees Fahrenheit and 109 degrees Fahrenheit. Outside that range, the unit may not be able to handle the load. 

If you have a relatively small space or want to tightly manage the temperature of your home, a ductless mini-split system is a great option for homeowners. Ensure that you have the system installed by a qualified, licensed professional and as long as you continue regular maintenance on the system you should enjoy years of worry-free convenience and comfort in your home.

How To Shut Down Your AC This Fall

How To Shut Down Your AC This Fall

We’re already into fall! The leaves are changing and soon enough, winter will be on its way. As homeowners prepare their preferred heating sources, they should also be worried about keeping their AC units safe. You won’t be using your AC all winter and you need to shut it down and protect it from bad weather. The last thing you want is to bring out your AC next year and discover it’s broken beyond repair. If you follow our advice, you can keep your AC from being ruined by the winter weather.

Here’s how to properly shut down your AC for the winter:

Finish your last-minute repairs

Before you start shutting down your AC, you should make sure your AC doesn’t need any repairs. Letting an AC problem linger over the winter can only make it worse. If there are any problems, call us to repair it before you shut it down.

Turn off the outside power

Turning off your AC unit’s power requires more than shutting off the indoor unit. Your outdoor condenser also needs to be cut off from the electricity. If the condenser still has power, it can turn on if there’s a warm spell and suck in snow and ice, damaging it. To shut off your condenser, look on the side of your house or under a flip-up lid nearby your condenser. Turn off the switch, and your AC is shut off (don’t forget to turn it back on when you want to use it.) However, there’s still more to do.

Examine and clean your condenser

Since you’re working with the condenser, you should give it some attention. Clean away any debris around or on your condenser with a broom before washing down the outside cabinet with a low-pressure spray from your hose. While it dries off, check the condenser for any damage or broken seals. If you see any problems, let us know the next time we help you out. Also, you should make sure the filter doesn’t need replacing.

Cover up the condenser

The last thing you need to do is cover up your condenser with a waterproof cover. Your local hardware stores likely sell them, but a waterproof tarp will work if it covers the entire condenser. Make sure to use some bungee ropes to secure the cover or tarp down so it doesn’t get blown away.

Signs That Your AC May Be Harming Your Air Quality

Signs That Your AC May Be Harming Your Air Quality

  • Cooling
air quality service by North Shore Home Energy

Did you know that a cooling system that is damaged, outdated, or running inefficiently can negatively affect your air quality? This can lead to several, potentially harmful situations in your home. Because bad air quality can be so hazardous, it’s important that you know the potential causes and symptoms. Here are some AC problems that may affect air quality and how they can affect you:

AC Problems That May Affect Your Air Quality

  • You have a dirty filter. Your filter is responsible for literally filtering out impurities in your airflow before its delivered and dispersed throughout your home via a central air system. Your air filter should be changed often, every few months is best. This is especially important during periods of extended use, as the summer months. When the filter becomes dirty and clogged with dust, hair, dander, pollen, or any other debris that may make their way in, your air quality can be compromised.
  • Excess water. If your air conditioner is leaking any excess fluid or it has more condensation than usual, it may be harming your indoor air quality. Leftover liquids can leave you with mold or mildew growth. These spores can grow and spread at a rapid rate. If in or around your air system, they can easily be blown into your home.
  • Duct problems. If your duct system is compromised in any way, it’s possible for debris to build up inside. Because your ducts deliver air directly through your vents, whatever may be built up inside will be delivered as well.
  • Loud noises and strange odors. These are signs that your system may be broken or running inefficiently. In an effort to prevent the problem from worsening, you should have a professional fix the problem.
  • Old or inefficient equipment. Any system that is old, outdated, or running inefficiently has the potential to damage the air quality in your home. If your air conditioning system is out of date, you should consider a replacement. Newer technologies are more efficient and will help to keep the air in your home safe and breathable for years to come.

Warning Signs

You may not know immediately that your AC is harming your air quality. If you suspect that your cooling system may be affecting you, it’s important that you call a North Shore Home Energy professional immediately. Here are some signs to watch out for:

  • Increase in respiratory illnesses
  • Worsened asthma symptoms
  • Increase in allergy symptoms
  • Reduced lung function
  • Fatigue
  • Headaches

Importance of Routine Maintenance

In order to keep your HVAC systems running safely and efficiently, routine maintenance is absolutely necessary. Not only will it save you from expensive repairs down the line, but it will also help to protect against dangerously low air quality. Symptoms may vary depending on the level of air pollutants present in your home, but you should never ignore the signs – no matter how small they may be.

At the first sign of an issue, call North Shore Home Energy!
