Annual Fuel Utilization Efficiency (AFUE)
A measure of a gas furnace’s efficiency in converting fuel to energy the higher the rating, the more efficient the unit. For example: A rating of 90 means that approximately 90 percent of the fuel is used to provide warmth to your home, while the remaining 10 percent escapes as exhaust.
British Thermal Unit (BTU)
This is the amount of heat it takes to raise one pound of water one degree Fahrenheit. For your home, it represents the measure of heat given off when fuel is burned for heating or the measure of heat extracted from your home for cooling.
Comfort-R™ Airflow System
An exclusive feature of a high efficiency home comfort system from Trane. This method of ramping airflow gives you greater humidity control in cooling and provides warmer air during heating start up.
Condensor Coil or Outdoor Coil
In an air conditioner, the coil dissipates heat from the refrigerant, changing the refrigerant from vapor to liquid. In a heat pump system, it absorbs heat from the outdoors.
Found in ductwork, this movable plate opens and closes to control airflow. Dampers can be used to balance airflow in a duct system. They are also used in zoning to regulate airflow to certain rooms.
Evaporator Coil or Indoor Coil
The other half of your air conditioning system located inside your home in the indoor unit. This is where the refrigerant evaporates as it absorbs heat from the air that passes over the coil.
A chemical that produces a refrigerating effect while expanding and vaporizing. Most residential air conditioning systems contain R-22 refrigerant. R-22 is regulated by international controls under the Montreal Protocol and in the United States by the Environmental Protection Agency. It is scheduled to be in production until the year 2020. It’s used in approximately 95 percent of air conditioning equipment manufactured in the U.S. today.
Seasonal Energy Efficiency Ratio (SEER)
A measure of cooling efficiency for air conditioners and heat pumps. The higher the SEER, the more energy efficient the unit. The government’s minimum SEER rating is 10. (It’s similar to comparing miles per gallon in automobiles.)
Seasonal Extreme Environmental Test Lab (SEET)
This is Trane’s torture chamber for heating and air conditioning systems, where five years of service are condensed into 16 torturous weeks. If a product doesn’t make it through our SEET lab, it’s not manufactured. We push our equipment to extremes because we’d rather test them in our lab than in your home.
