Rheem

Rheem gas furnaces are designed to last a lifetime. They are among the greatest choices for those who want to install or replace a furnace, with easy-to-service panels, diagnostic systems, and award-winning designs and features.

The propane and natural gas furnaces from Rheem are known for being simple to install and maintain. Most of Rheem's 21 gas furnaces include built-in PlusOne Diagnostics, an industry-first 7-segment LED display that quickly identifies problems, reducing the need for service calls. Rheem furnaces aren't as energy-efficient as their competitors, with the majority having an AFUE of 80 percent and only a few reaching 96 percent. However, if you're searching for a furnace that's simple to use and maintain, Rheem is an ideal option.
