Some of the Best Gas Furnaces You Can Buy in Mobile

Our Dave Lennox Signature® Collection gas furnaces are some of the best you can find. They’re also some of the quietest operating systems you can buy and offer efficient heating for your Mobile area home.

Our 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 a much higher temperature is demanded. These furnaces may save your family a significant amount on utility bills.
