Did you know the air inside your home is 2-5 times more polluted than the air outside?

Homes today need ventilation – especially since we spend so much time indoors. In fact, new homes today are required under the Ontario Building Code to have ventilation systems.

Dr HVAC provides installations, repairs, and maintenance services for heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems. Our technicians are fully licensed experts who will always make sure everything is working properly before they leave.

HRV Systems

A heat recovery ventilation system (HRV) is designed to get rid of stale air in your home AND bring in fresh air without losing heat (or cool air in the summer).

With an HRV, you’ll breathe healthier air all year round without sacrificing warmth or the money it costs to heat your home in the first place.

How Does an HRV System Work?

An HRV has a heat exchange core. This transfers the heat from your stale outgoing air to the fresh, incoming air.

In the summer, the process is reversed so that your home stays cool. While an HRV is mainly used for fresh air, it also does a great job of keeping your home comfortable all year round.

What is the Difference Between HRV and ERV?

An energy recovery ventilator (ERV) is quite similar to an HRV, but it will also transfer humidity. This helps keep your home at optimal humidity levels in each season. This is a huge help to your air conditioner in the summer.

So which one should you choose: an HRV or an ERV? It all depends on your home’s environment. For homes that are humid in winter, we recommend an HRV. But for homes that are too dry in the winter, an ERV will make more sense.

Our home comfort specialists can perform a thorough inspection of your home and present you with some options that will work best for your indoor climate.
