Efficiency Rating

80% AFUE

On January 1, 2023, the Department of Energy (DOE) will require new testing procedures for developing efficiency ratings on split system air conditioners. Products that have gone through these updated testing procedures will display SEER2 and EER2 ratings, in addition to the older SEER/EER ratings. The 2023 testing procedures are more stringent and will result in lower efficiency ratings compared to the older ratings. As we transition all our products to these new testing procedures, we’ll publish both ratings on our air conditioners category page for better comparison.

Blower Motor

Multi-speed ECM blower motor and single-stage gas valve provide improved levels of even temperature control and comfort

Blower Motor

The blower motor helps circulate heated air through the ductwork and distributes it evenly throughout the home for consistent indoor comfort.

Heating capacity

40,000 - 100,000 BTUh

Heating capacity

Heating capacity for a furnace refers to the amount of heat a furnace can produce to warm a space, measured in British Thermal Units per hour (BTUh).

Operation

Single-stage operation

Operation

A single-stage unit operates at full capacity when on, a two-stage unit has two levels of operation (low for mild heating needs and high for maximum heating), and a modulating unit continuously adjusts its output to match the precise heating demands, offering more efficient and consistent temperature control.
