Some of the Best Gas Furnaces You Can Buy in Liberty

If you’re in need of a gas furnace replacement in Kansas City, our Dave Lennox Signature Collection gas furnaces are the best option. These products are a couple of the quietest gas furnaces out there and are highly energy efficient.

We’ll start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which conserve energy by only operating fans at full speed when extreme heat is required. Variable speed motors use 2/3 less energy than single speed motors and may help your family save hundreds of dollars on utility expenses each year compared to other furnaces.

Product specifications for each Dave Lennox Signature Collection gas furnace model are provided below. If you want to talk with a Air Unlimited Heating & Cooling staff member about one of our products in Kansas City, call 816-286-7258 or make an appointment online.
