Some of the Best Gas Furnaces You Can Buy in Rapid City

If you’re in need of a gas furnace replacement in Rapid City, our Dave Lennox Signature Collection gas furnaces are an excellent choice. These products are a couple of the quietest gas furnaces available and are highly energy efficient.

Let’s start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces include variable speed motors, which limit energy use by only operating fans at full speed when extreme heat is required. Variable speed motors use two-thirds less energy than single speed motors and may help your family save hundreds of dollars on yearly utility expenses compared to older furnaces.

Product details for each Dave Lennox Signature Collection gas furnace model are included below. If you’d like to talk with a Street Heating & Sheet Metal Inc staff member about one of our products in Rapid City, call 605-342-5107 or set up an appointment online.
