Product Overview
When harsh winter weather strikes, nothing compares to the warmth and safety a powerful reliable gas furnace can provide. While furnace heating technology has been around for decades, not all systems are created equally. Some are definitely better than others. One of the best on the market is the MRCOOL single stage, 80% AFUE gas furnace. This system can be installed down flow, and is designed to operate for decades, provide powerful heating capability, and, best of all, keep your heating bill affordable at the same time. It does the latter via its 80% AFUE energy efficiency rating. That mark of quality ensures 80% of every dollar you spend on heating fuel gets turned into real, effective heat for your home.

Manufacturer Warranty
Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.
