Your home’s indoor quality (IAQ) could be 2-5 times worse than the outdoor air. Newer homes are at a high risk since tighter homes leak less to outside thus trapping air inside – thus the need of a better ventilation system.

Signs a home needs more fresh air: windows that fog or frost on the inside, stale air in bedrooms by morning, and cooking smells that linger.

A tight Calgary home needs a planned supply of fresh air. An HRV brings it in and sends stale air out, while keeping most of the heat.

ERV or HRV – Which to choose?

The best choice between an ERV and an HRV is dependent on the climate and specific needs.

• If your house is too humid in winter (above 60% RH) then an HRV is the better choice, as it would surely get rid of excess humidity while an ERV would tend to keep it at a high level.
• If your house is too dry in winter, then an ERV would be a better choice as it helps retain humidity, eliminating the need (and cost) for you to generate it through other means.

In summer, the use of an HRV will normally increase the level of humidity inside your home, so an ERV is greater in hot and humid zones. But a dedicated dehumidifier will highly likely do the trick there. At the very least, the ERV will lower the load on the air conditioning system, even if it can’t keep up with the high humidity level on the outside.

Therefore, there is not one right choice between ERV & HRV systems. It totally depends on the climate, lifestyle and the home itself.

Energy Efficient.

Do you want know what’s the best part?

Having an HRV system at your home is very cost efficient! You can SAVE hundreds of dollars to your electricity bill, because instead of you using turning on the air conditioner at your room or blowing the air on your electric fans you will now have an – all-in-one system that will do the job for you! Lesser usage of appliances means MORE savings on your utility bills and you also contribute to lesser carbon use on the planet and keep your home comfortable for your family!

Avoids condensation.

Condensation is one of the most prevalent problems that homeowners have, and it is also the most common source of moisture in homes. The HRV system will eliminate all of the water vapor created, resulting in no moisture condensation and the prevention of dampness, rot and mold growth.

Convenient in terms of size.

The heat recovery ventilation system is small enough to fit your basement, attic, or adjoining garage. Some types can be installed in a hot-press in the kitchen. The primary control unit is typically installed in the utility room or kitchen, but it can be installed anywhere in the house to meet your needs.
