Lennox is more than HVAC. It’s a promise.

Lennox air conditioners and heat pumps with two-stage technology have the flexibility to run at either a low or a high setting, depending on how much cooling is needed. Since the low setting can meet household demands most of the time, a two-stage unit uses less energy and produces more even temperatures.
