Some of the Best Gas Furnaces You Can Buy in Phoenix

If you’re in need of a gas furnace replacement in Phoenix, our Dave Lennox Signature Collection gas furnaces are all great options. These systems are two of the quietest gas furnaces out there and are highly 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 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 other furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are explained below. If you’d like to talk with a Dial One Mears Air Conditioning & Heating Inc staff member about one of our products in Phoenix, call 602-997-5701 or make an appointment online.
