Energy Efficient Furnaces

Energy Star Logo

Our furnaces meet or exceed the energy efficiency standards set by Natural Resources Canada. These standards require that all gas furnaces have a minimum efficiency rating (AFUE) of 90%, and must be independently tested and verified. Our energy efficient furnaces help you save money on your heating bill every month, and ensure you stay comfortable all winter long.

Most of our furnaces actually exceed the minimum standards, and are also Energy Star® certified. We carry furnaces up to 98% efficient, the highest efficiency level available on the market today. If you have any questions about which models are right for your energy efficiency requirements, we’d be happy to help.
