Ideal for tightly sealed homes, Lennox® whole-home Healthy Climate® ventilations systems replace stale indoor air with clean outdoor air, making your home feel fresher and less stuffy.

Better than opening a window, which can let allergens and bugs into your home, a Healthy Climate ventilation system allows you to easily and efficiently control the amount of fresh air coming into your home. 

Well-suited for colder climates and dry or desert-like areas, the Healthy Climate Heat Recovery Ventilator (HRV) harnesses heat from inside your home and transfers it to the incoming fresh air. This heat recovery process enhances your comfort and helps control wintertime condensation, which can damage windows, insulation and furniture.

Ideal for warmer and more humid climates with mild winters, the Healthy Climate Energy Recovery Ventilator (ERV) transfers moisture and heat from incoming fresh air to the outgoing airstream. In fact, it can remove nearly half of the moisture from the incoming air, helping to keep your home cool and dry. 

Unlike some indoor air quality systems on the market, both the HRV and ERV systems freshen the air without producing ozone, a known lung irritant.
