Some of the Best Gas Furnaces You Can Buy in Chicago

If you’re looking for a gas furnace replacement in Chicago, our Dave Lennox Signature Collection gas furnaces are all great options. These systems are two of the quietest gas furnaces you can find and are extremely energy efficient.

Let’s start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which limit energy use by only operating fans at full speed when an extreme change in heat is required. Variable speed motors use 66% less energy than single speed motors and may help your family save hundreds of dollars on utility expenses each year compared to other furnaces.

Product details for each Dave Lennox Signature Collection gas furnace model are explained below. If you want to talk with a iTemp Heating and Air Conditioning professional about one of our products in Chicago, call 773-704-0640 or schedule an appointment online.
