Some of the Best Gas Furnaces You Can Buy in Hattiesburg

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 Hattiesburg area home.

Our two Dave Lennox Signature Collection gas furnaces feature variable speed motors, which allow more comfort than typical single speed furnaces. In a variable speed furnace, blower fans start up slowly and only operate at their highest speed when there’s an extreme demand for heat. These furnaces may save your family hundreds on utility expenses.
