Some of the Best Gas Furnaces You Can Buy in Manassas Park

If you’re looking for a gas furnace replacement in Manassas Park, our Dave Lennox Signature Collection gas furnaces are an excellent choice. These models are two of the quietest gas furnaces out there and are highly energy efficient.

Let’s begin with energy efficiency. Our Dave Lennox Signature Collection gas furnaces are built with variable speed motors, which save energy by only running fans at full speed when extreme heat is required. Variable speed motors use 2/3 less energy than single speed motors and may help your family save hundreds of dollars on yearly utility expenses compared to standard furnaces.

Product details for each Dave Lennox Signature Collection gas furnace model are included below. If you want to talk with a Woody's Sudden Service Inc team member about one of our products in Manassas Park, call 703-369-5528 or make an appointment online.
