Some of the Best Gas Furnaces You Can Buy in Laguna Niguel

Top-of-the-line 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 San Joaquin Hills area home.

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