So why use an ERV?

A properly operating air conditioner will not only lower the temperature in your house, but will also lower the humidity level. This prevents an uncomfortable cold and damp situation.
In fact, about 2/3 of the energy used by the air conditioner system is to remove moisture. Therefore, when ventilating with an ERV in the summer, less moisture brought into the home means less work for the air conditioner, more confort and energy savings for you.
Besides , if the indoor air is too dry (during the winter) for optimal comfort, an ERV help recovering the moisture and the latent energy.
