Conditions in a house get stuffy during winter. The doors and windows must stay closed to keep heat trapped inside. The only way to enjoy any fresh air that sweeps out the stale and polluted air is to open up windows—and who wants to do that when it’s below freezing outside?
But there’s a solution. Open doors and windows aren’t actually the only way to enjoy fresh air. We can install a device called an energy recovery ventilator (ERV) in your HVAC system that lets you enjoy fresh air all winter without the chills.
