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
No Hassle 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.
Communicating Capability
The ability of the HVAC system's components to exchange information and work together seamlessly. This allows for more precise control, better energy efficiency, and the ability to adjust settings remotely or automatically based on the system's performance, environmental conditions, or user preferences.
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.
