Some of the Best Gas Furnaces You Can Buy in Florissant

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

These Dave Lennox Signature Collection gas furnaces include variable speed motors, which allow more comfort than traditional single speed furnaces. Variable speed furnaces’ blower fans start up slowly and only operate at full speed when there’s an extreme demand for heat. These furnaces may save your family a substantial amount on your energy bills.
