AFUE: Annual Fuel Utilization Efficiency. 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.

BTU: British Thermal Unit. 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.

CFM: Cubic Feet Per Minute. A standard measurement of airflow. A typical system requires 400 CFM per ton of air conditioning.

Capacity: The output or producing ability of a piece of cooling or heating equipment. Cooling and heating capacities are referred to in BTUs.

Comfort-R™ Airflow System: An exclusive feature of a high efficiency home comfort system from Trane. This method of ramping up airflow gives you greater humidity control in cooling and provides warmer air during heating start up.

Compressor: The heart of an air conditioning or heat pump system. It is the part of the outdoor unit and pumps refrigerant in order to meet the cooling requirements of the system.

Condenser Coil: In an air conditioning system, the coil (sometimes referred to as an outdoor coil) dissipates heat from the refrigerant, changing the refrigerant from vapor to liquid. In a head pump system the coil absorbs heat from the outdoors in the heating mode of operation.

Damper: 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.

Ductwork: Pipes or channels that carry air throughout your home. in a home comfort system, ductwork is critical to performance - in fact, it's as critical as the equipment.

Gas Furnace Heat Exchanger: Located in the furnace, the heat exchanger transfers heat to the surrounding air, which is then pumped throughout your home.

HSPF: Heating Seasonal Performance Factor. This rating is used in measuring the heating efficiency of a heat pump. the higher the number, the more efficient the unit.

Humidifier: Used to inject water vapor into the dry, heated air expelled from a furnace/air handler.

HVAC: Heating, Ventilating and Air Conditioning. Used to refer to the industry at large, particularly dealers of heating and air conditioning.

HVAC Humidifier Coil: Located inside your home either inside the air handler or in the enclosure attached to the furnace. As part of an air conditioning system, the HVAC Humidifier Coil (often referred to as an evaporator or indoor coil) absorbs heat from the air that passes over the coil. In a heat pump system the coil dissipates heat to the air passing over the coil.

Packaged Unit: A heating and cooling system contained in one outdoor unit. A packaged unit is typically installed either beside, on top of the home, or sometimes in the attic.

Refrigerant: A chemical that produces a refrigerating effect while expanding and vaporizing. Most residential air conditioning systems contain either R-22 or R-410A refrigerant.

SEER: Seasonal Energy Efficiency Ratio. 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.)

SEET: Seasonal Extreme Environmental Test lab. This is Trane's torture chamber for heating and air conditioning systems, where five years of service are condensed into 16 tortuous 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.

Split System: The combination of an outdoor unit (air conditioner or heat pump) with an indoor unit (furnace or air handler). Split systems must be matched for optimum efficiency.

Thermostat: A thermostat consists of a series of sensors and relays that monitor and control the functions of a heating and cooling system.

Ton: A unit of measurement for determining cooling capacity. One ton is the equivalent of 12,000 BTUs per hour.

Trane Comfort Specialist™: A Trane dealer who is committed to ongoing training and to providing premium service and customer satisfaction.

Zoning: A method of dividing a home into different comfort zones so each zone can be independently controlled depending on use and need.
