Some of the Best Gas Furnaces You Can Buy in Florissant

If you’re in need of a gas furnace replacement in Florissant, our Dave Lennox Signature Collection gas furnaces are the best option. These systems are two of the quietest gas furnaces out there and are very energy efficient.

We’ll start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which save energy by only operating fans at full speed when extreme heat is required. Variable speed motors use two-thirds less energy than single speed motors and can help you save hundreds on yearly utility expenses compared to other furnaces.
