Dave Lennox Signature® Collection Gas Furnaces Stand Out from All the Rest

If you’re looking for a gas furnace replacement in Aurora, our Dave Lennox Signature Collection gas furnaces are the best option. These models are two of the quietest gas furnaces you can find and are extremely 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.

More details for each Dave Lennox Signature Collection gas furnace model are included below. If you’d like to talk with a Service Plus Mechanical staff member about one of our products in Aurora, call 630-809-6319 or schedule an appointment online.
