Some of the Best Gas Furnaces You Can Buy in Winchester

If you’re in need of a gas furnace replacement in Winchester, our Dave Lennox Signature Collection gas furnaces are an excellent choice. These systems are two of the quietest gas furnaces you can find and are extremely energy efficient.

We’ll start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces include variable speed motors, which limit energy use 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 your annual utility bills compared to other furnaces.

More details for each Dave Lennox Signature Collection gas furnace model are included below. To talk with a Thornberry Bros Inc professional about one of our products in Winchester, call 859-745-1564 or make an appointment online.
