Some of the Best Gas Furnaces You Can Buy in Westminster

If you’re searching for a gas furnace replacement in Denver, our Dave Lennox Signature Collection gas furnaces are an excellent choice. These products are two of the quietest gas furnaces available and are extremely 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 working fans at full speed when extreme heat is required. Variable speed motors use 2/3 less energy than single speed motors and can help you save hundreds on utility expenses each year compared to other furnaces.
