Some of the Best Gas Furnaces You Can Buy in Greenville

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

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