Even on the most humid days, Lennox Precise Comfort^® technology keeps temperatures exactly where you set them, using only the energy that’s needed.

Perfect degree of cool

There’s cool, and there’s perfectly cool. Many Lennox® air conditioners make the distinction with two-stage technology.

Lennox^® air conditioners are amongst the quietest and most energy efficient units on the market. Delivering perfectly precise comfort control, Lennox air conditioners continually make small adjustments in fan speed and cooling output to hold your temperature exactly where you want it. Offering industry-leading efficiencies of up to 26.00 SEER, Lennox air conditioners can help you save hundreds of dollars every year in utility costs. And since some of the units are ENERGY STAR^® certified, they may even qualify you for federal energy tax credits and local utility rebates. In addition, a number of Lennox air conditioners work with iComfort^® S30 and iComfort^® E30 smart thermostats, giving you even more control over your home’s comfort—whether you are at home or away.
