HVAC Dictionary Terminology, Abbreviations & Air Conditioning Glossary of Terms & Definitions

In an effort to extend our customer service online, we at NY NJ A/C Connection have compiled a glossary of terms often heard regarding air conditioning services.
Air Handler: Air handler, or coil boiler, circulates cooled or heated air throughout the ductwork of a building and is the indoor part of an air conditioner or heat pump.
British Thermal Unit (BTU): The BTU is a measurement of heat energy. One BTU of heat is required to raise one pound of water by one degree Fahrenheit. A high BTU rating is the reflections of the greater heating capacity of the system. .
Central Air-Conditioning System: Cooled air originating at a central location that is distributed to and from rooms with the use of one or multiple fans through a series of ducts.
Composite Fan Blades: Designed to improve operation and durability, these blades are constructed with rugged materials and an exclusive, unique angle.
Compressor: A compressor compresses and pumps refrigerant to sustain cooling requirements and is a component of the outdoor air conditioner or heat pump.
Condenser Coil: The condenser coil, or outdoor coil, is a component of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year.
Cubic Feet Per Minute (CFM): A measurement of the cubic feet of air that passes by a stationary point in one minute. The higher the number of CFM reflects more air being moved through the ductwork by the system.
Damper: Damper is a moveable plate that regulates airflow and directs it to areas that need it most, which is typically used in zoning application and is located in the ductwork.
Department Of Energy (DOE): A federal agency that regulates setting industry efficiency standards and monitoring the consumption of energy sources.
Dry-Charged Unit: An air conditioner or heat pump that is shipped dry and charged with refrigerant at the place of installation.
Ductwork: The tubing by which treated air is channeled throughout a building.
Energy StarĀ®: Energy Star is attached to HVAC products that meet or exceed federal guidelines for energy-efficient performance, a designation give by the U.S. Environmental Protection Agency (EPA) to which the.
Evaporator Coil: The evaporator coil, or indoor coil, is the part of an air conditioner or heat pump that absorbs the heat from the air.
Heat Pump: Removes heat from the house and releases it outdoors.
Humidifier: An indoor air quality enhancing product that adds moisture to heated air as it passes from the furnace into the ductwork for distribution throughout the home.
HVAC: Heating, Ventilation and Air Conditioning system.
Minimum Efficiency Reporting Value or MERV Rating: This describes the size of the holes in the filter that allow air to pass through. The higher the MERV rating the finer the holes in the filter are allowing for higher efficiency.
Packaged Unit: A packaged unit is a heating and cooling system contained in one outdoor unit.
Programmable Thermostat: A thermostat with the ability to record different temperature and time settings for home heating and/or cooling equipment.
R-22 Refrigerant: Now being phased out by the U.S. EPA, this is the old refrigerant standard for residential air conditioners.
R-410A Refrigerant: A chlorine-free refrigerant that meets the U.S. EPA’s newest, most stringent environmental guidelines.
Refrigerant: A chemical that produces a cooling effect while expanding or vaporizing. Refrigerant Lines: Refrigerant lines are two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil.
Seasonal Energy Efficiency Ratio (SEER): The SEER is an energy efficiency rating applied to air conditioners, the higher the SEER, the more efficient the unit is.
Split System: A heating and cooling system that involves an indoor and outdoor unit, as well as a thermostat.
Thermostat: A device that controls, monitors, and adjusts heating and cooling equipment.
Two-Stage Operation: Two-stage operation provides two levels of heating or cooling output for enhanced temperature control, energy efficiency, and indoor air quality.
Variable Speed Motor: Precisely controlled distribution of heated and cooled air throughout the building by a motor that operates on a wide range of speeds.
Ventilator: Responsible for exchanging the stale and re-circulated indoor air with fresh, filtered outside air.
Zoning System: A heating and cooling system that creates customized temperature zones throughout the home for increased comfort and efficiency.
