Lennox Indoor Air Quality Systems

Why is ventilation important for proper indoor air quality?

At one time, it was possible to achieve natural ventilation in our homes by simply opening a window. However, with growing concerns about rising energy costs, we have been busy making homes "tighter" from an efficiency standpoint. Armed with weather stripping and caulk guns, we have eliminated air leaks from our homes. Unfortunately, that means contaminants have no way to escape.

Pollutants in your home's air can cause poor indoor air quality, which in turn may cause dizziness and headaches, plus aggravate allergies and asthma. That's why Lennox offers ventilation systems that help remove contaminants by exchanging stale, recirculated indoor air with fresh, filtered outside air.
