Should you turn your air exchange only when the heat is on?

    Air exchangers are used for filtering and bringing fresh air into an area. Most times, air exchangers are used during the winter because they are designed to not only maintain the room's temperature, but also bring in fresh air from outside.

    During the summer months, there are advantages and disadvantages to both. Leaving the vent open allows more fresh air in, but also draws more heat and makes your air conditioner work harder. Leaving the vent closed won't bring as much heat in, but you would be relying more on filtered air. You aslo would be intruducing humidity. Then on cooler summer days people tend to open widows defeating the porpose of having it on during the summer.
