Buying Guide – Air Exchanger


Studies have shown that most people spent 90% of their time inside their home. Also, houses’ modern construction does so that they are so well isolated that they imprison polluting particles and humidity inside. Results: more than 50% of Quebec homes are showing high humidity signs. According to specialists, installing an air exchanger and adequate ventilation allows, not only to clear the air but also, to reduce allergies’ pulmonary diseases’ symptoms.

In a recent home, it is considered that the volume of air has to be completely replaced minimally each two or three hours. In old buildings, a part of this air renewal is ensured continuously, by the lack of airtightness of windows’ and doors’ joints, which is not the case in new homes. For this reason, the air exchanger is not only a device that is increasingly sophisticated and accessible, but also more and more popular; it has now become mandatory in all new constructions.

Tran Climatisation offers you this buying guide that will provide you with all the information you need to make a judicious purchase of a brand new air exchanger.

Air Exchanger

How does an air exchanger work?

Since most of recently built homes are airtight and very well isolated, the air loads up with humidity and polluting matters, created by human activity. Installing an air exchanger in your home contributes taking out the polluted air outside the house to replace with a clean and cool air, with no allergens, and no polluting particles. Most of air exchangers available on the market do have a heat recovery core.

In a distinct ductwork – to prevent contamination – the polluted air and the clean air are going through the recovery core. The fresh air coming from the outside captures this heat and when it attains the desired temperature; it is redirected in all the rooms by the distributed system.

The installation of an air exchanger, but also ductwork that goes everywhere in the house. If you already have a central heating system, ventilation or central air conditioning system, your air exchanger’s installation will be easier. An air exchanger is also used to evacuate the excessive humidity in your home. When it detects a humidity level that is too high, it starts evacuating ambient air outside. It also proceeds to an air filtration. When the humid air is taken outside, it goes through a filter that captures dust, pollen, mildew and other polluting agents and allergens. The process remains when cool air of the outside is brought inside; out coming humid air can heat up the incoming air, thus contributing to maintain a clean environment, a balanced temperature and also, a constant air flow in the house.

What are the advantages of an air exchanger?

Most of the human activities are causing humidity variation and pollution in the air. An air exchanger that is well installed and well-calibrated ensures a constant air renewal; which is essential to maintain good health and comfort. A controlled airflow ensures the evacuation of polluted air generated by human activities: humidity, bad odors, tobacco, pet air, dust, cleaning products’ fumes, radon, etc. If you are using a heating system fueled with gas (furnace, fireplace or stove), these devices produce carbon dioxide, carbon monoxide and nitrous oxide that are important to evacuate to prevent grave dangers for your health.

An air exchanger also contributes reducing and balancing the humidity level that tends to rise if the ventilation is insufficient. Even if it is mainly caused by plants, humidity also comes from cooking, laundry, perspiration and breathing. If it is not quickly regularized, humidity can become mildew and cause serious damage, not only to your health but can make your house insalubrious.

A study done in 2010 by Dr. Tom Kovesi, specialized in child respiratory diseases, in the Qikiqtaaluk community, in Nunavut, community where the child pulmonary diseases are extremely high, proved that a heat recovery air exchanger has significantly improved the symptoms of respiratory illnesses of children. It can do the same thing at your home. If a family member or you are suffering from asthma, allergies or pulmonary disease, installation of an air exchanger will reduce allergens, dust and other atmospheric irritants in the air.

What are the types of air exchanger available on the market?

Technological development and recent conception of air exchangers have made them extremely efficient and reliable devices. There are currently three types of air exchangers on the market: the standard air exchanger, the heat recovery air exchanger and the energy recovery air exchanger.

  • Standard Air Exchanger: This standard system remains the less expensive. It filters the air and rejects excessive humidity. Its main advantages are it allows avoiding condensation problems, like mildew on windows’ ledges. It also improves the air quality by capturing most of the particles and polluting matters that can cause respiratory problems. Finally, it contributes eliminating bad odors (tobacco, cooking, and humidity, cleaning products).
  • Heat Recovery Air Exchanger: Also called heat recovery ventilator, the heat recovery air exchanger, this devices remains one of the most popular models of air exchangers. It has the same features than a standard air exchanger, but it has a heat recovery core, most of the time, made of aluminum and polypropylene. This core allows it to recover most of the heat in the rejected air, in order to transmit it to the incoming cool air. This air exchanger type allows you to significantly reduce your heating fees, while benefiting from a clear, dehumidified air.
  • Energy Recovery Air Exchanger: This type of device, even more sophisticated than the two others, not only allows recovering heat, but also recovers most of humidity to maintain an acceptable humidity level all year long. Since this air exchanger can preserve an acceptable humidity level during winter and summer, it acts like a “mini heat pump”. Then again, you save money on your heat and energy bills, while improving these devices efficiency, hence the name, energy recovers air exchanger.

Choosing your air exchanger: practical tips and tricks

The first questions you should ask yourself before buying an air exchanger are: what are my needs? Are there any animals in the house? Is there anyone in my family who suffers from pulmonary illnesses or allergies? Is there a smoker in your home? These are questions that the specialized contractor of Tran Climatisation will ask you to determine which air exchanger you need.

  • Count the number of rooms and the volume of your home : An air exchanger must be chosen according to the number of rooms, the number of people, and not its size. The air quality is determined by the level of human activity that influences the humidity level variation and the amount of polluting matter in the air.
  • Opt for the heat recovery air exchanger: This criteria remains one of the most important ones prior to purchase. If you want to do some savings, it can be judicious to choose an Energy Star improved air exchanger that has a motor that consumes less energy and that guarantees a minimal heat recovery of 65%.
  • Choose an efficient filtration system: Some air exchangers already have an HEPA (High-efficiency particulate absorption) filter. Very popular on the air quality market, the HEPA filter is famous for its capacity to capture up to 99, 97% of allergens and other microscopic particles, and significantly reduce symptoms related to allergies, asthma and other pulmonary illnesses.
  • Opt for an electronically commutated motor: This type of motor remains the most efficient for an air exchanger that continuously functions. The main advantage of these high-efficiency motors is that they remain operational at low speed, while remaining quiet and consuming less electricity. Finally, these motors ensure a better distribution of the air while improving your comfort.
  • Choose the proper capacity for your air exchanger: An air exchanger’s capacity is calculated in FPM (foot per minute – this represents the capacity of the airflow.) Your air exchanger’s capacity is determined by your home’s volume. With a free quote, Tran Climatisation’s team of specialists can help you to choose an air exchanger according to its capacity to ensure you have an air of quality, while saving on your energy bills.
  • Choose an aluminum core for heat recovery: As an essential part of the heat recovery heat exchanger, an aluminum heat energy core offers a better capacity of recovering heat than the polypropylene core. A high-quality air exchanger with an aluminum heat recovery core can recover up to 70% of the energy of the polluted air sent outside.
  • Verify the noise level of your air exchanger: Since an air exchanger in continuously in operation, remember to choose a model that produces as less noise as possible. Most of the time, air exchangers models of recent conception are very quiet while remaining efficient.
  • Call a specialist for help: If you want to make sure that your house has enough space and all necessary to have an air exchanger, call a specialist at Tran Climatisation and schedule an appointment to precisely evaluation all your installation. He can also advise you of the different models that will fit your needs and budget.

    Frequently Asked Questions (FAQ)

    Do you have any more questions for us? We have gathered the most frequently asked questions from our customers who wish to purchase an air exchanger or simply want to learn more about it. Do not hesitate to contact us if you need any information about air exchangers and we will be happy to help you.

    Why should I buy an air exchanger?

    It has been proved that an air exchanger can improve the air quality in your home on the first day of its installation. Since you spend 90% of your time inside, it is important that you breathe an air of quality. Also, an air exchanger reduces the humidity level in your home while decreasing the pollution and allergens in suspension in the air.

    What is the average price of an air exchanger?

    Numerous factors can influence an air exchanger’s cost: model, type, capacity, brand, etc. If you wish to learn more about the air exchangers’ price, do not hesitate to contact Tran Climatisation for more details!

    Can an air exchanger create humidity?

    An air exchanger does not create humidity, on the contrary. It is used to evacuate the exceeding humidity during winter and balance the humidity level during summer.

    What type of filters should I use for my air exchanger?

    Many types of filters exist on the market; each one of them has its own particularities and meet different needs. Have a look at the list below to learn more about the most popular types of filters:

    • HEPA Filter: From far the most popular and most efficient filter on the market, the HEPA filter can capture up to 99,97% of particles and dust as small as 0,3 microns (some virus, allergens, cigarette smoke, radon, combustion fumes).
    • Folded Filter: This synthetic filter that is reinforced with cotton and captures particles in suspension with an efficiency rate of 72% to 1 micron and above (dust, smoke, animal hair).
    • Charcoal Filter: This filter made of polyester soaked with active charcoal that forms an absorbing matter and purifying wall. It efficiently captures odors, gas and particles with an efficiency rate of 90% at 10 microns.
    • Foam Filter: The foam filter is cleanable and captures up to 25% of particles in suspension of 1 micron and more.

    Can I install my air exchanger by myself?

    Even if the air exchanger is a relatively easy device, we strongly recommend that you contact our specialists at Tran Climatisation to install your air exchanger. They are professionals with many years of experience, who have all the necessary skills to do this type of installation. After the installation, our technician takes the time to verify everything and to explain its functioning to you.

    Can I do the maintenance of my air exchanger by myself?

    Even if it is strongly recommended to have your maintenance done by a certified technician, there are a few easy tasks that you can do by yourself.Before you start the maintenance, you must not forget to unplug your air exchanger to avoid any accidents.

    • Clean the filters: It is recommended to verify the state of your filters once every three months. For cleanable filters, you can either clean them with a vacuum or clean them with hot and soapy water. Be sure to let the filters dry out in the open before putting them back. For non-cleanable filters (like electronic and electrostatic filters), it is better to ask the help of a professional technician.
    • Outdoor Air Intake: By doing a regular inspection, you can take out the grass, snow, ice and leaves that can obstruct the air intake. You can also vacuum it to clean the duct that links up the air intake to the main device.
    • Indoor Air Intake: It is also important to frequently clean the polluted air induction vents’ grates. A trick to reduce the dirt accumulation in the air duct, add a filter on the grate. However, be sure to clean this filter often.

    If you wish to have a complete maintenance of your air exchanger, do not hesitate to contact Tran Climatisation, and one of our certified technicians will come to help you.

    Are there regulations and requirements for air exchangers in new constructions?

    Most of contractors know about the regulations regarding air exchanger’s installation in new homes. Tran Climatisation’s team always know about upcoming regulations about air exchangers and will apply them during the installation.

    I have an air exchanger: why do I still have condensation in my windows?

    Your air exchanger is made to evacuate the exceeding humidity during winter. However, during cold days, it is normal that ice and condensation forms in your windows. Many factors can cause this phenomenon: windows’ quality, heating temperature, bad isolation, windows’ obstruction (blinds, curtains), dominating winds, brutal temperature changes, etc.

    If you want to reduce ice formation and condensation in your windows, don’t completely put down your blinds and curtains in your windows; this would prevent heat from reaching it, thus, increase the condensation risks. If you can, take off the indoor mosquito screens.Don’t wait to heat your home, especially the basement. This will allow to evacuate all the humidity accumulated during summer.

    How can I measure the humidity level?

    If you want to measure the humidity level in your home, there is a simple and cheap way to do so: you can buy a small device called hygrometer. The hygrometer will be able to confirm you if the humidity level in your home is acceptable. You will find two types of hygrometers on the market: an electric hygrometer and a mechanical hygrometer.

    In order to efficiently measure the humidity level in your home, put your hygrometer where humidity signs are most likely to appear. It is important not to install your hygrometer close to a heating source, a chimney or any other device susceptible to distort your results.For a house with 4 people, the acceptable humidity level is between 35% and 45% during winter, and 50% during summer.

    What are the advantages of a heat recovery air exchanger?

    For a few years now, the heat recovery air exchanger’s popularity doesn’t cease to grow in Quebec, because it has many advantages.Having the same characteristics as the standard air exchanger, the heat recovery air exchanger has a heat recovery core (made of aluminum and polypropylene) that captures heat particles of the rejected air – between 60% and 80% – before transmitting it to the incoming air. This device can help you reduce your heating bills. Also, the heat recovery air exchanger allows you to regulate the humidity level in your home and have an improved air circulation.

    What is the difference between an air exchanger and an air purifier?

    The principle of functioning of an air purifier is simple : it is a portable or a stable device, that has an air intake and filter system which enable it to capture particles present in the air during the passage of air in the device. When portable, the air purifier can be put anywhere in the house. You can also add it to your heating or ventilation system.

    An air exchanger, like its name, creates an air exchange between the inside and the outside of the house, while filtrating the indoor air and absorbing the humidity. Unlike the air purifier, the air exchanger has a more powerful air flow, and in the case of an air exchanger with heat recovery, it can become an auxiliary heating system and, thus, reduce your energy bills.
