Some of the Best Gas Furnaces You Can Buy in Colfax

If you’re searching for a gas furnace replacement in Colfax, our Dave Lennox Signature Collection gas furnaces are the best option. These models are some of the quietest gas furnaces available and are extremely energy efficient.

Let’s start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces are built with variable speed motors, which conserve energy by only running 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 older furnaces.

Product specifications for each Dave Lennox Signature Collection gas furnace model are provided below. To talk with a Ackerman Heating & Air Conditioning team member about one of our products in Colfax, call 509-397-3622 or schedule an appointment online.
