Top 5 Reasons for Air Conditioner Failures

Last month, you fulfilled your curiosity about how air conditioner parts function together to cool the air in your home. That knowledge is all good and dandy, but there are more questions to be answered. Do you know the reasons why an air conditioner would fail and what to do in the event that it does? Below is a breakdown of the top 5 reasons for an air conditioner’s failure.

Faulty Circuit Breaker, Fuse or Electrical Wiring

If your air conditioner fails, first check your fuse and circuit breaker to make sure that there aren’t any electrical issues present. Turn off your air conditioner, allowing 15 minutes of cool down time before replacing the fuse or resetting the breaker. If that doesn’t do the trick, your AC could have been improperly wired or you could have tripped a high-pressure limit switch. In those cases, call a trained technician to inspect the problem.

Refrigerant Leak

A refrigerant can leak for several reasons: natural wear and tear, formic acid buildup, or formaldehyde exposure. Over time, acid can build up, burning a hole through the copper tubing or coils of the air conditioning unit, resulting in a leak and a change in pressure. If an air conditioner does not reach an adequate pressure level, this can cause it to fail.

TIP: If you see a refrigerant leak, call a trusted HVAC technician immediately! Refrigerants are harmful substances to the environment.

Frozen Coils

Air conditioners need a passageway for warm air to travel in order to reach the cold coils that cool the air. If there is a blockage within this passageway, your coils can freeze from a lack of warm air passing over the coils. To prevent this issue, change your AC filter regularly and don’t skip your HVAC maintenance inspections! If you see frost, call us!

Age & Wear and Tear

Is your air conditioner 5 years or older and constantly toggling on and off? This could be a sign that there is damage to one or more parts within your unit, such as the fan blades, compressor, or electrical parts. Regular inspections can catch these issues before they become too large to fix.

Faulty Thermostat

If your thermostat is not properly calibrated, it can cause your air conditioner to work harder than it needs to. Thermostats exist to control the amount of air being circulated within your home. If the thermostat is faulty, it can send your air conditioner into overdrive.

Air Conditioner Deconstruction: How It Functions

You know that an air conditioner brings joy to your life during the hot summer months, but are you ever curious about how it works? An air conditioner essentially works by transferring heat and humidity found inside your home to the outside. In order to understand why an air conditioner would fail (covered in next month’s blog), you must first understand how it functions.

To break it down, there are 7 essential parts of an air conditioner.

The evaporator, comprised of cooling coils, removes heat from the air using a refrigerant. A refrigerant is a substance that changes states from a low-pressure gas to a high-pressure liquid as it absorbs heat. As a blower ‘blows’ air over the coils, this substance cools the air. At the exterior of the house, a condenser, made up of hot coils accumulates all of the hot air and releases it back into the outside world.

In order for the evaporator and condenser to work together in unison, a compressor, with the aid of a fan, exists to pump refrigerant between the two, chilling the air, dispersing and dissipating it as it travels. Within the air conditioning unit, there is also a filter whose job it is to remove particles, like dust and debris, from the air in your home. Lastly, a thermostat exists to regulate the level of cool air being distributed.

Top 3 Frequently Asked HVAC Questions Heading Into The Summer

HVAC systems keep your home comfort and safety in check, but do you know how they work to maintain this comfort and safety? For the average homeowner, these high-tech systems can be tricky to understand. That is why we have honed the expertise of our Afterglow specialists to answer our most frequently asked questions leading into the summer.

“We made it through the winter with our old furnace/boiler. Can we wait for the fall to replace it?”


We get it, everyone wants to save money if they can. But when it comes down to your furnace or boiler, we highly recommend that you don’t wait! Just because your furnace or boiler survived the winter does not mean it is working efficiently. You may be investing more money the longer you wait. Why? Your air-conditioner relies on your furnace to blow air throughout your home. If that furnace is not in good shape, it could cause your AC to stop working entirely. In the summer months —this is not a problem anyone wishes to have! Do not suffer from heat in vain. Replace your furnace or boiler now so that you are not rushed when the colder weather hits!

“Does the efficiency of an air conditioner really make much of a difference?”


If you like saving money and the environment, yes, air-conditioner efficiency matters! AC efficiency is measured in SEER (Seasonal Energy Efficiency Ratio), which is the rating calculated by the amount of cooling outputted during a typical cooling season divided by the electrical energy (BTU) inputted during that same time period. Essentially, the higher the SEER rating, the more energy efficient the unit is. For the average Canadian home running their AC from March to September, a bump up one point in SEER may result in savings of $10-$15 per month!

“If I have a boiler at home, can I even get air conditioning?”


Many of our clients think that if they have a boiler installed, they are out of luck with an AC system because boiler systems do not use ducts to transport heat throughout the home. That is not the case! Air conditioner technology is becoming more and more inventive! Ductless options with wall-mounted AC heads are available and can be quite cost-effective. These powerful systems can cool rooms or even entire floors quite rapidly, saving you at the hottest time of the year! Ducted systems are also available and can work alongside your boiler.

You asked, we answered! Do not suffer in the scorching heat this summer. Bask in the cool air you always dreamed of! Do you have any HVAC questions nagging you? Contact us —our HVAC specialists would be happy to help provide you with some clarity and expert advice!

Beware: Spring & Summer Allergies Are Near

The delayed winter snow has nearly melted, and you are giddy with thoughts of spring and summer adventures. Much to your surprise, your throat begins to itch in between bouts of coughing and sneezing fits. You think you can take refuge within the confines of your home but symptoms persist. What causes these torturous allergic reactions and is there anything you can do to limit their torturous effects? Find out below.

Hay Fever

Spring and summer allergies are primarily caused by the release of pollen into the air. As the weather warms up, trees, grass, and weeds begin to grow, producing little grains of pollen. The pollen travels by wind for miles, settling on many surfaces in its wake, including up the nostrils of unsuspecting and undeserving allergy victims. The human immune system, in turn, reacts by releasing the antibody, histamine, into the victims’ bloodstream to combat the unwanted intruder. This is where the pesky symptoms kick in!

Remember, during this time, the wind will be your enemy and rain will be your best friend. Pollen spreads more profusely when winds blow, so during these times, close your windows tightly to reduce allergy flare-ups. It would also be wise to replace any wind-pollinating plants in your home or garden.

Digesting Pollen

During these windy days, pollen can also land on the produce you consume! For those with allergies, make sure you wash all of your fruit and veggies to ensure that you are not consuming an unwanted kind of ‘snack.’

That being said, don’t avoid eating produce altogether! Eating bright coloured fruits and veggies, such as oranges, grapefruit, carrots, red peppers and watermelon can help you become you again. Rich in Vitamin C and bioflavonoids, these delicious treats lessen the punch of hay fever by tackling the symptoms that ail you. While you’re at it, try eating some apples and red onions as well! They contain a natural antihistamine, quercetin, which can relieve those itchy eyes and throat.

Insect Nibbles

As the warmer weather approaches, insects appear! This might be great for the environment, but if you suffer from allergies, their presence could spell trouble. Fire ant, honey bee, hornet, and wasp bites are quite common in Canada during the warmer months. They can cause painful swelling, itching, redness, and in some drastic cases, anaphylaxis. Protect yourself by wearing insect repellants whenever walking through heavily forested areas and keeping an eye out for these pests. If you think you might have been stung and are having trouble breathing, do not wait! Seek help immediately.

Smoke & Smog Triggers

When you think summer, you think of roasting spider-dogs on the campfire or road trips to the beach, right? While these are exciting plans, both are known to trigger allergic reactions in humans. Inhaling campfire smoke and the air pollutant, smog, can affect the way you breathe. To be safe, avoid standing directly in the way of campfire smoke and car exhausts.

These next few months are full of excitement and adventures, but when those dreaded allergies hit, don’t let them cut into your time to explore! Protect yourself, your family and your home by tackling them head-on. Our dedicated staff at Afterglow would be pleased to assist you with removing allergens from your home.

3 Ways to Be Kind to Your Home

January is a time to reflect and make some changes for the New Year. Sometimes, those changes can be small, like reading more or cutting down on alcohol; other times those changes can be monumental for one’s success and well-being. This year, make your health and home a priority. Set your standards high by being kind to yourself and your home. Below, we have outlined 3 simple ways to do just that.

Keep Boilers and Water Heaters Maintained

Boilers essentially work by pumping water through copper tubing, rapidly heating the water in the process. Unlike water heaters, boilers are used for larger scale heating initiatives such as heating pools, hot tubs, and whole complexes. On the other hand, water heaters heat and store water in tanks, and are generally used for smaller-scale heating projects. When you add heat to the mix, it is important to stay on top of maintenance, in case of any potential hazards from wear and tear. Regular maintenance inspections can mitigate the risk of fires caused by burners, pilot lights, gas pressure, and heat exchangers. They can also prevent water backflow and reduce safety concerns with venting, piping, and carbon monoxide gas.

Replace Furnace Filters Regularly

Furnace filters are used to collect dust, dirt and pollutants so that they do not circulate throughout your furnace and HVAC system. When these filters are clogged, it takes more time and energy to run a furnace properly, leading to more frequent repairs or replacements. As you can imagine, this can drastically increase your utility bills and the overall costs associated with continuous technical support. The simple and inexpensive act of changing your filter regularly can enhance your HVAC system’s efficiency and save on costs in the long run!

Don’t forget about the wonders clean furnace filters can have on your health! By changing your filters regularly, you can prevent the built-up debris from floating back into the air, polluting it, and introducing it back into the air you breathe.

Purchase A Humidifier

Humidifiers work by restoring moisture back into your home’s air. Air can become very dry and stale, particularly during the winter months. This can result in dry skin, congestion, allergies, and the spread of airborne viruses. Investing in a humidifier can help prevent all of those pesky ailments we associate with winter. We recommend consulting with an HVAC specialist before choosing a humidifier, simply because there are many different sizes and model options that work best in different environments.

Ratty Radiator: Refurbishing Your Old HVAC Units

Hunting for a home can be a challenge, especially with the way the housing market has been looking lately. Now add the new home vs old home debate into the mix and you’re sure to be even more confused! New homes have that clean look and fresh smell that homeowners love. However, there is something to say about the charm and durability of an older home. Older homes have a unique structural design, are often found in desirable locals close to city centres, and are constructed with high-quality materials. If you want the best of both worlds, there are ways you can renovate your home, keeping safety and HVAC in mind.

Ratty Radiator – Towel Rack Transformation

I am sure you’ve heard of the term ‘vintage’ being thrown around in the last decade or so. More and more people are infusing their homes with vintage elements to get that unique flare and old-school charm. A few weeks ago we got the chance to revamp a ratty radiator, featured below, by making it into a fully functioning heated towel rack for one of our fantastic clients!

HVAC Vintage Finds

This project inspired us to explore other ways homeowners can renovate their old or new home, by keeping the elements they love intact. Check out this old boiler and German-style thermostat we found online! If you have one of these kicking around your home, instead of throwing it out, incorporate it into your interior design. This will add that little bit of history to your home’s otherwise cookie-cutter construction.

Old A/C DIY Project

Do you have an old air conditioning unit in your home that stylistically you just don’t know what to do with? Instead of moving or tearing your wall apart, try covering it up using inexpensive wood panelling. Vintage Meets Glam transformed the look of her bedroom by doing just that!

Safety First

DIY projects can be exciting and fun, however, working with HVAC units, whether functioning or not, could pose safety risks. Before starting a project like the ones above in your home, talk to a professional to determine whether or not a risk is present. Stay safe and happy decorating!
