should you run an air exchanger in the summer

by August Beier PhD Published 3 years ago Updated 2 years ago

Do you run an air exchanger in the summer? Answer: No. Air exchangers do not create humidity but if the outside air is humid, they will bring this humidity into your home. Example: running an air exchanger on high in the summer.

The answer depends on your home's air conditioning system, your ERV wall control, the outdoor temperature and, most importantly, the outdoor relative humidity. As a rule of thumb, if you are more comfortable outside than inside your house, you should run your air exchanger in the summer.Oct 27, 2020
