Some of the Best Gas Furnaces You Can Buy in Denver

If you’re in need of a gas furnace replacement in Denver, our Dave Lennox Signature Collection gas furnaces are the best option. These systems are some 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 running fans at full speed when an extreme change in heat is required. Variable speed motors use 2/3 less energy than single speed motors and may help your family save hundreds of dollars on your annual utility bills compared to older furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are explained below. To talk with a Northglenn Heating & Air Conditioning, Inc. professional about one of our products in Denver, call 303-452-4146 or make an appointment online.
