What Is an Energy Recovery Ventilator? Why Should I Use One?

It goes without saying that Arizona is a very hot, dry place to be for the majority of the year. Homeowners in this area tend to run their air conditioning systems nonstop throughout the long, arduous cooling season. We also tend to seal up our homes pretty tightly, so that we are not wasting energy when trying to cool our homes. This can put our indoor air quality in Mesa, AZ on the chopping block, though.

If you use an ERV, or energy recovery ventilator, however, this need not be the case. These devices are helping countless homeowners to strike a balance between efficient cooling and great indoor air quality. Read on and contact us to learn more. 

What Exactly Does an ERV Do?

An energy recovery ventilator is a mechanical ventilation device. As mentioned above, it is natural that we seal up our homes tightly, considering the fact that we run our air conditioners so much. The problem with this is that air conditioners dehumidify the air as they operate. If your home is sealed up very tightly, you may not have to worry about heat coming and making your AC work harder than it should have to, driving up energy costs. However, it also means that your home is not enjoying the natural ventilation that helps to keep the air fresh.

With an ERV, you can bring fresh air into your home without the efficiency concerns you’d have if you were just to open up the windows. This is because the ERV performs some heat transfer in the process. When the cool, stale air is vented out of your home, it absorbs heat from the fresh, but hot, air that is coming in. This pre-cools the air, helping to take some strain off of your AC while also “recovering” the energy that you used to cool that outgoing air in the first place. Plus, the two air streams mix just enough to allow for the optimization of humidity levels.
