Glossary
AFUEAnnual Fuel Utilization Efficiency. Indicated as a percentage, your furnace's AFUE tells you how much energy is being converted to heat. For example, an AFUE of 90 means that 90% of the fuel is being used to warm your home, while the other 10% escapes as exhaust with the combustion gases. Advanced Reciprocating CompressorType of compressor that uses a more efficient process for compressing refrigerant for better cooling efficiency. Air HandlerThe portion of your air conditioner or heating system that forces air through your home's ductwork. BTUBritish Thermal Unit. Used for both heating and cooling, BTU is a measure of the heat given off when fuel is combusted. Or for cooling, it's a measure of heat extracted from your home. (One BTU is approximately equal to the heat given off by a wooden kitchen match.) BTUHA British Thermal Unit (BTU) is the unit of heat required to raise 1 pound of water by 1 degree Fahrenheit. BTUH is British Thermal Units per Hour. Beckett BurnerA burner assembly within your oil furnace, manufactured by Beckett to exact specifications of Carrier. This burner provides good combustion of heating oil. CFMStands for Cubic Feet per Minute. A measurement of airflow that indicates how many cubic feet of air pass by a stationary point in one minute. The higher the number, the more air is being forced through the system. CapacityThe ability of a heating or cooling system to heat or cool a given amount of space. For heating, this is usually expressed in BTUs. For cooling, it is usually given in tons. Carbon MonoxideA colorless, odorless, highly poisonous gas produced when carbon-based fuels, such as natural gas, burns without sufficient air nearby. Comfort Heat TechnologyCarrier's exclusive Comfort Heat Technology® accurately predicts the need for heating while cutting temperature swings in half. Comfort Heat Technology Pump SystemComfort Heat Technology® Pump System is Carrier's exclusive heat pump system that provides significantly warmer supply air from the registers for enhanced occupant comfort. CompressorPart of a split-system heat pump or air conditioner's outdoor unit that controls the pressure applied to the refrigerant, necessary for taking in heat to warm your home with a heat pump or getting rid of heat to keep your home cool. Condenser CoilPart of the outdoor portion of a split-system air conditioner or heat pump. By converting refrigerant that is in a gas form back to a liquid, the coil sends heat carried by the refrigerant to the outside. DBDecibels (dB) are a unit measuring the intensity of noise. DamperA type of "valve" used in duct work that opens or closes to control airflow. Used in zoning to control the amount of warm or cool air entering certain areas of your home.

Products with the ENERGY STAR rating will be efficient and save cost on energy bills. Electronic Air Cleaner (EAC)An electronic device that filters out large particles and contaminants in indoor air. It then electronically pulls out tiny particles that have been magnetized, such as viruses and bacteria, drawing them to a collector plate. Energy Saver SwitchAn energy-saver switch causes the air conditioner's fan and compressor to cycle on and off together, reducing energy use. Evaporator CoilPart of a split-system air conditioner or heat pump located indoors. The evaporator coil cools and dehumidifies the air by converting liquid refrigerant into a gas (or vice-versa). A blower moter, typically in a furnace, then moves air over the coil to either heat or cool your home. Fan CoilAn indoor component of an air conditioner or heat pump system, used in place of a furnace and evaporator coil, to provide change the refrigerant from a gas to a liquid (or vice-versa) and blow air over the coil to cool or heat your home. HSPFThe Heating Seasonal Performance Factor is a measure of the heating efficiency of a heat pump. The higher the HSPF number, the more efficiently the heat pump heats your home. HVACTerm used for Heating, Ventilation, and Air Conditioning. Heat ExchangerThe part of a furnace that transfers heat to nearby air. Heat PumpA product that works just like an air conditioner in cooling mode; however, in heating mode, the refrigerant flow is reversed and heat is extrated from the outside air too heat your home. Horizontal FlowA type of furnace, installed on its "side", that draws in air from one side, heats it and sends the warm air out the other side. Most often used for installations in attics or crawl spaces. HumidifierA piece of equipment that adds water vapor to heated air as it moves out of the furnace. This adds necessary moisture to protect your furnishings and reduce static electricity. Hybrid HeatHybrid Heat systems deliver exceptional performance by using a heating source that provides the most energy-efficient comfort during moderate heating conditions. IdealDefrostIdealDefrost is Carrier's proprietary defrost management innovation for maintaining the ideal defrost interval for a heat pump, enhancing comfort and efficiency. IdealHumidityIdealHumidity™ is Carrier's proprietary humidity management innovation for maintaining the ideal comfort in a home. Indoor Coilsee Evaporator Coil Load EstimateA series of studies performed to determine the heating or cooling requirements of your home. An energy load analysis uses information such as the square footage of your home, window or door areas, insulation quality and local climate to determine the heating and cooling capacity needed by your furnace, heat pump or air conditioner. When referring to heating, this is often known as a Heat Loss Analysis, since a home's heating requirements are determined by the amount of heat lost through the roof, entry ways and walls. Low BoyLow Boy is a type of furnace configuration in which the furnace is lower in height and occupies more floor space. MERVThe Minimum Efficiency Reporting Value is the standard comparison of the efficiency of an air filter. The MERV scale ranges from 1 (least efficient) to 16 (most efficient), and measures a filter's ability remove particles from 3 to 10 microns in size. Matched SystemA heating and cooling system comprised of products that have been certified to perform at promised comfort and efficiency levels when used together, and used according to design and engineering specifications. Operating CostThe day-to-day cost of running your home comfort equipment, based on energy use. Outdoor Coilsee Condenser Coil Payback AnalysisOverall measure of the efficiency and value of your home comfort system. By combining your purchase price and ongoing operating costs, a payback analysis determines the number of years required before monthly energy savings offset the purchase price. Puron RefrigerantPuron® refrigerant is an environmentally sound refrigerant designed not to harm the earth's ozone layer. Federal law requires that all manufacturers phase out ozone depleting refrigerants in the next few years.
