Some of the Best Gas Furnaces You Can Buy in the Main Line

Our Dave Lennox Signature® Collection gas furnaces are some of the best of the best. They also have some of the quietest heating around and provide efficient heating for your the Main Line area home.

Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which help produce more comfort than traditional single speed furnaces. With a variable speed furnace, blower fans start up slowly and only operate at full speed when extreme heat is demanded. These furnaces could save your family hundreds on utility expenses.
