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.

What Our Customers Say About Us

"The guys were very friendly. They took lots of care and attention when removing the old furnace and replacing it with the new one to not damage anything along the way. Once finished they took the time to explain the operation and go through any questions we had. I would definitely use them again."

"This review is for Noel who came to my home to see why our electric air cleaner was not working. He was punctual and super friendly. Found the problem within 15 minutes. Had the part ordered, and 9 days later it literally only took him 3 minutes to replace it for us!"
