Some of the Best Gas Furnaces You Can Buy in Huntsville

If you’re in need of a gas furnace replacement in Huntsville, our Dave Lennox Signature Collection gas furnaces are all great options. These models are two of the quietest gas furnaces out there and are extremely energy efficient.

Let’s begin 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 two-thirds less energy than single speed motors and may help your family save hundreds of dollars on utility expenses each year compared to other furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are explained below. To talk with a All Weather Heating & Air Conditioning Inc staff member about one of our products in Huntsville, call 256-852-8825 or set up an appointment online.
