Some of the Best Gas Furnaces You Can Buy in Mobile

If you’re in need of a gas furnace replacement in Mobile, our Dave Lennox Signature Collection gas furnaces are an excellent choice. These models are a couple of the quietest gas furnaces available and are extremely energy efficient.

We’ll start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which limit energy use by only working fans at full speed when a large change in heat is required. Variable speed motors use two-thirds less energy than single speed motors and could help you save big on utility expenses each year compared to standard furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are provided below. If you’d like to talk with a Farnell Heating & Air Conditioning Inc team member about one of our products in Mobile, call 251-471-2674 or make an appointment online.
