Some of the Best Gas Furnaces You Can Buy in Las Vegas

Top-of-the-line 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 Clark County area home.

Our two Dave Lennox Signature Collection gas furnaces feature variable speed motors, which enable more comfort than older single speed furnaces. With a variable speed furnace, blower fans start up slowly and only operate at full speed when a much higher temperature is demanded. These furnaces can save your family a substantial amount on your energy bills.
