Some of the Best Gas Furnaces You Can Buy in York

Our Dave Lennox Signature® Collection gas furnaces are some of the best. Certain models are also some of the quietest systems available and offer efficient heating for your Southern Pennsylvania area home.

These Dave Lennox Signature Collection gas furnaces include variable speed motors, which allow more comfort than older single speed furnaces. With a variable speed furnace, blower fans start up slowly and only operate at maximum speed when extreme heat is demanded. These furnaces can save your family a significant amount on utility bills.
