Energy Star®
A program developed by the Environmental Protection Agency (EPA) in order to reduce the nation's energy consumption. Energy Star® qualified heating equipment can be up to 15 percent more efficient than standard models. Energy Star-qualified cooling equipment can be up to 7 percent more efficient than minimum-standard equipment.
AFUE
Annual Fuel Utilization Efficiency. AFUE is a rating that reflects how efficiently a gas furnace converts fuel to energy. An AFUE of 90 means that approximately 90 percent of the fuel is utilized to provide warmth to your home, while the remaining 10 percent escapes as exhaust.
SEER
Seasonal Energy Efficiency Ratio, a rating that measures the cooling efficiency of a heat pump or air conditioner. SEER and HSPF will vary, depending on the models and combination of the indoor and outdoor unit.
Comfort-R™
Comfort-R™ is American Standard's process for reducing your home's humidity and maintaining a comfortable temperature. Set by the dealer, Comfort-R™ ramps up the airflow in your home—making your home cooler and more comfortable faster.
Variable Speed Motor(s)
The fan motor inside higher efficiency indoor and outdoor units is designed to change its speed based on your home's requirements. Working in conjunction with your thermostat, it keeps the appropriate-temperature air (e.g., warm air on cold days) circulating throughout your home, reducing temperature variances. The variable speed motor also increases dehumidification and is quiet because it runs at a lower speed most of the time. Plus, the consistent air circulation eliminates noisy startups and shutdowns.
Two-Stage Cooling & Heating
Two-stage cooling and heating is considered to be more efficient, because it operates at low speed most of the time. However, on days when more heating or cooling is required, it switches to the next stage for maximum comfort. |
