Over the last few years, we hear more and more about air exchangers. Why? What exactly do air exchangers do, and why are they important?

 


 

The Popularity of Air Exchangers

Why are air exchangers so popular? The answer is simple. Modern homes are more airtight.

New building codes require new construction to be better insulated than before. This makes sense considering it keeps our homes warm during the winter and cool during the summer. This factor is essential in our Quebec climate.

On the other hand, this improved insulation also means that stale air remains in your home for longer. Pollutants like CO2 and humidity are trapped in your home. When humidity is trapped in your home, mould can grow.

According to construction codes, any newly built homes or homes enlarged by 50% or more must be equipped with a Heat Recovery Ventilator (HRV). Here’s where the air exchanger comes into play!

 

The Anatomy of an Air Exchanger

Air exchangers transport fresh air into your home while expelling stale air outdoors.

There are two main types of air exchangers – Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV).

The ERV transfers incoming humidity to the evacuating air during summer. During winter months, it does the opposite, transferring expelled humidity into the incoming air. This type of system is ideal in areas that experience high humidity outdoors and a lack of humidity indoors.

The HRV eliminates humidity with the evacuated air during winter while recycling the heat back into the incoming air. This helps to lower indoor humidity levels.

 

The Benefits of an Air Exchanger

A good ventilation system is required by Canadian building codes. What are the benefits of having one?

Air Quality. According to Canada Health, Canadians spend 90% of their time indoors. Children spend the most time indoors, preferring video games and computers over outdoor play. With the pandemic and confinement, many have had less opportunity to get out, particularly in metropolitan areas like Montreal. It’s thus crucial to have good air quality. Air exchangers help eliminate contaminants from the air, reducing the degree of related health problems.

Eliminates Humidity and Mould. With balanced levels of humidity in the home, you can say goodbye to foggy windows, moisture rundown, and mould.

Equalized Air Pressure. An air exchanger allows a continuous flow of fresh air in the home, avoiding negative pressure. Negative air pressure allows drafts to enter anywhere they can. This is particularly problematic when a home has a fireplace. Air exchangers regulate the air pressure and save you a lot of headaches.

 

Why is it Important? Why is an air exchanger important?

Firstly, a ventilation system is required by law in new construction. Secondly, it is an asset for both your health and your home. Even if your home is a little older, it can be highly beneficial for you and your family to install an air exchanger.

In order to be sure of optimal air quality, it’s important to keep up regular maintenance for your unit.
