AFUE
Gas furnaces use Annual Fuel Utilization Efficiency (AFUE) as their efficiency measurement. The higher the AFUE, the greater the efficiency and the greater your energy savings potential



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
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
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.
* No Hassle Replacement™ Limited Warranty: If compressor, coil or heat exchanger fails due to defect during the applicable No Hassle Replacement limited warranty time period, a one-time replacement with a comparable unit will be provided.
+ 10 Year Parts Limited Warranty: Timely registration required for 10-year parts limited warranty and lifetime limited heat exchanger warranty. Limited warranty period is 5 years for parts and 20 years for heat exchanger if not registered within 90 days of installation. Jurisdictions where warranty benefits cannot be conditioned on registration will receive the registered limited warranty periods. Please see warranty certificate for further details and restrictions.
