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.
These 7 parts are essential for the lower temperature bliss you crave during the humid summer months. If you are in need of an air conditioner, contact us! Our knowledgeable technicians would be happy to help you find the right unit to fit your home!
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!
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.
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.
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.
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.

Spring brings with it the joys associated with warmer weather: hiking, nature walks, lounging outside on the deck with a drink in hand. However, it is also the time when the dreaded C word comes out to play. Don’t let ‘cleaning’ get you down! Sometimes all you and your home need is a little TLC to raise your spirits. Here are 5 spring cleaning and housekeeping tips to get you back into the groove of things.
Dry Your Humidifiers & Dehumidifiers
Humidifiers and dehumidifiers are tremendously beneficial for adding and eliminating moisture into and from your home; however, they come with their own health hazards. The body of the units tend to store water residue within, creating the perfect breeding ground for bacteria to collect and for mould to form. It is important to dry these cavities fully after use in order to prevent unhealthy particles from infiltrating the air you breathe.
Poke AC Drainage Holes
Every once in a while it is a good housekeeping idea to poke a paperclip into the drain hole located beneath your air conditioner’s evaporator fins. This hole’s purpose is to drain condensation from the interior of the unit outwards. If it is blocked by debris, your AC will not run at full capacity, causing you to spend more money over-time.
Caulk Window & Doors
As many homeowners will be able to tell you, even the best of caulkings do not last a lifetime. Weathering takes its toll. Therefore, it is important to give your windows and doors a bit of a refresher every couple of years. If you notice the sealant cracking or changing into that gross yellowish colour, you can bet moisture is making its way into your home. Seal that moisture out!
Change Toilet Flappers
Toilet flapper or flush valve malfunctions are the most common reason for toilet leaks. Over time, this flapper—whose job it is to periodically turn the fill valve on-and-off, draining water within its core—ages and stops sealing the toilet valve, causing leakage into the bowl. Stop wasting money on water! If you notice your toilet’s flapper not sealing properly, save yourself the hassle of cleaning up a big mess in the future and get yourself a new one!
Replace Furnace Filters
Furnace or AC filters keep the air blowing into your home nice and fresh! If these filters are clogged with dust and debris, they will not do their job properly, spreading allergens into the air. If you don’t want to change your filters every month, invest in a HEPA filter which only has to be changed every 6 months and can be cleaned with a vacuum in between replacements!
The C word does not have to be overwhelming. The tips above are simple enough to get your home spring ready in no time! In need of more helpful HVAC tips? Contact us for answers to your questions! One of our knowledgeable and reliable HVAC specialists would be happy to assist you!
Keeping your family safe should always be a top priority, but what if you don’t know what types of dangers lurk within your own home? Sometimes good intentions are no match for unforeseen circumstances. Take the first step and educate yourself on any potential HVAC issues that may arise in your home. Below are 4 danger signs you should look out for.
Rotten Egg Smell
Did you walk into your home only to smell the stench of rotten eggs? Leave and call your gas company immediately. Natural gas furnaces are one of the most popular home heating choices due to their convenience, energy efficiency, and cost-effectiveness. However, be aware of the dangers associated with a gas leak. Natural gas in itself is odourless, so the harmless yet poignant chemical mercaptan is added to the compound in order to warn home occupants that a gas leak has occurred. Gas leaks are dangerous because they can not only spark fires, but inhaling large amounts of natural gas can also reduce the oxygen levels in your body, causing dizzy spells, shortness of breath, and in serious cases, even death! Do not look for the source, simply GET OUT!
Does your HVAC unit give off an electrical smelling odour as if something is overheating? It very well could be! If it is your first time turning on your furnace in a long time, this scent could just be built-up dust burning off. But if it does not dissipate after 30 minutes, it could signal something more serious. Turn off your unit if the smell continues, and first check your air filters for dust and debri. If your air filters are clear, your furnace or air conditioning motor may be damaged or burned out. If left unchecked, this can lead to a fire. Turn off your electricity on your master switch, and contact your trusty HVAC professional as soon as possible!
If you start to smell a musty whiff of air near your air conditioning unit that isn’t going away, this is a sure sign that there is moisture somewhere nearby. The biggest issue is not the smell. Built-up condensation from the unit can migrate up into your air-ducts, creating mould. Prolonged mould exposure can lead to respiratory issues if not dealt with in a timely fashion. If you notice this warning sign, contact your HVAC service agent to perform a much-needed duct cleaning!
Have you noticed a puddle of water pooling around your air-conditioning unit lately? This can happen as summer approaches. When the evaporator coil in your unit cools the warm air being blown over it, it creates moisture. This condensation drips into a pan and down a condensate drain pipe that leads to the outside. When this pipe is blocked up by sludge, mould, dust and debris, the water has nowhere to go, causing the water to back up. Taking care of this issue quickly is highly recommended to prevent water damage to your floor and foundation. This will also make sure mould does not begin to form.
Do not turn a blind eye to these warning signs! Keeping your family safe depends on your due diligence. If you smell rotten eggs, electrical overheating, must and mould, or see water leaking from your air-conditioning unit, seek help from HVAC and gas professionals who are trained to safely eliminate these issues.
