Some of the Best Gas Furnaces You Can Buy in Plainfield

If you’re in need of a gas furnace replacement in Plainfield, our Dave Lennox Signature Collection gas furnaces are the best option. These systems are some of the quietest gas furnaces you can find and are highly energy efficient.

Let’s start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which conserve energy by only working fans at full speed when extreme 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 your annual utility bills compared to older furnaces.
