The key to a healthy, comfortable home starts with the air with which we live and breathe. Lennox is dedicated to the pursuit of perfect air and it’s been a driving force behind their innovations since 1895. Making air cooler, warmer, dryer, cleaner and better with premium, award-winning systems that are exceptionally quiet and energy efficient.

Lennox offers some of the quietest, most efficient, most capable home heating, cooling and indoor air quality products you can buy.

Every Lennox® product has been engineered to deliver best-in-class comfort and efficiency. And when two or more Lennox products are working together as part of a system, the results are truly outstanding.

As a Lennox® Dealer, Pro-Tech HVAC Home has been trained to deliver a level of comfort and service that exceeds your expectations.

Depending on the model you choose, basic limited warranty periods for heating and cooling units can range from 5 years to the lifetime of the appliance.


Lennox System Overview

Whatever your home, lifestyle and budget, there’s a Lennox system that can meet your needs:

The Lennox Home Comfort System is made up of four major components: a thermostat, a furnace, an air conditioner unit or heat pump, and an indoor air-quality system. All these components work together to optimize your home’s comfort, improve your home’s indoor air quality, and maximize your home’s energy efficiency. 


Imagine pure, clean freshness that lets you breathe easier. The silent flow of air to every room. Temperatures that stay exactly where you want them. The Ultimate Comfort System™ makes it all possible. It’s the most advanced, efficient, capable heating and air-conditioning system Lennox has created.

A dual-fuel system uses two energy sources-an electric heat pump and a gas furnace-to provide the ideal combination of efficiency and comfort. It seamlessly alternates between gas and electricity, depending on outdoor conditions. When it gets very cold, around 35°F, the heat pump shuts down and the furnace takes over.
