Some of the Best Gas Furnaces You Can Buy in Greenville

If you’re in need of a gas furnace replacement in Greenville, 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 extremely energy efficient.

We’ll start with energy efficiency. Our Dave Lennox Signature Collection gas furnaces feature variable speed motors, which limit energy use by only working fans at full speed when an extreme change in heat is required. Variable speed motors use two-thirds less energy than single speed motors and could help you save big on utility expenses each year compared to older furnaces.

Product specifications for each Dave Lennox Signature Collection gas furnace model are explained below. If you’d like to talk with a Ken Parker Service Inc team member about one of our products in Greenville, call 903-883-2829 or schedule an appointment online.
