HRV and ERV systems are designed to allow fresh air to enter the ventilation system of a home through an outdoor vent. The air then goes through a process called counter-flow heat exchange that pre-heats or pre-cools it. The air afterwards enters your home closer to the desired indoor temperature, and this takes a tremendous amount of stress off the AC and heater.

More detail on how it works: The HRV/ERV runs the fresh outdoor air through an opposite current of stale indoor air. In cold weather, the cool outdoor air will gain heat from the warm indoor air. In hot weather, the warm indoor air will lose heat to the cool indoor air. Essentially, the system "recovers" the energy originally used to cool or heat the indoor air and passes it on to the incoming air. You'll enjoy a more pleasant indoor environment without making massive sacrifices on your energy bills.

"What's the difference between an ERV and an HRV?" you're probably asking. The answer is, "Not much," but your home will be suited more to one than the other. The major difference between the two is that an energy recovery ventilator also transfers moisture between the two currents of air, so it assists with humidity control. However, a heat recovery ventilator is more effective in colder climates. Trust to your professional installer to decide on which type of ventilator will do the exact job you require from it.
