HVAC & Air Conditioning Glossary of Terminology & Abbreviations
Air Handler: Found the indoor part of an air conditioner or heat pump, the air handler is what circulates cooled or heated air throughout the ductwork of a building.
British Thermal Unit (BTU): A high BTU rating indicates a greater heating capacity of the system, which is the measurement of heat energy. One BTU of heat is required to raise one pound of water by one degree Fahrenheit.
Central Air-Conditioning System: Originating at a central location, the cooled air is distributed and cycled throughout the rooms with the use of one or multiple fans and a system of ducts.
Composite Fan Blades: Constructed with rugged materials and an exclusive unique angle, Composite Fan Blades are engineered to improve operation and durability.
Compressor: A compressor is a component of the outdoor air conditioner or heat pump that compresses and pumps refrigerant to sustain cooling requirements.
Condenser Coil: The condenser coil is a component of an air conditioner or heat pump that, depending on the time of the year, either releases or collects heat.
Cubic Feet Per Minute (CFM): The more volume of air being moved through the ductwork by the system is indicated with a higher CFM number. The CFM is a measurement of the cubic feet of air that passes by a stationary point in one minute.
Damper: Typically used in zoning application and is located in the ductwork, the damper is a moveable plate that regulates airflow and directs it to areas that need it most.
Department Of Energy (DOE): Monitoring the consumption of energy sources as well as regulates setting industry efficiency standards are done through the DOE, a federal agency.
Dry-Charged Unit: Charged with refrigerant at the place of installation, a dry-charged air conditioner or heat pump is a unit that is shipped dry.
Ductwork: A series of tubing by which treated air is channeled throughout a building.
Energy Star®: Energy Star is attached as designated label by the U.S. Environmental Protection Agency (EPA) to which the HVAC products that meet or exceed federal guidelines for energy-efficient performance.
Evaporator Coil: The evaporator coil absorbs the heat from the air and is found in the air conditioner or heat pump.
Heat Pump: Collects the warmth in the air from the house and releases it outdoors.
Humidifier: Used to add moisture to heated air as it passes from the furnace into the ductwork for distribution throughout the home; an indoor air quality enhancing product frequently utilized.
HVAC: Heating, Ventilation and Air Conditioning system.
Minimum Efficiency Reporting Value or MERV Rating: The MERV indicates the size of the holes in the filter that allow air to pass through. The finer the holes in the filter increase efficiency, which reflects the higher the MERV rating.
Packaged Unit: A heating and cooling system contained in one outdoor unit is considered a packaged unit.
Programmable Thermostat: A thermostat featuring the ability to apply separate pre-set recorded temperature and time settings for home heating and/or cooling equipment.
R-22 Refrigerant: This is the old refrigerant typically used for residential air conditioners but is now being phased out by the U.S. EPA.
R-410A Refrigerant: The U.S. EPA’s newest, most stringent environmental guidelines which is a chlorine-free refrigerant.
Refrigerant: To expand or vaporize to produce a cooling effect, refrigerant is the responsible chemical.
Refrigerant Lines: The two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil are the refrigerant lines.
Seasonal Energy Efficiency Ratio (SEER): The higher the SEER, the more efficient the unit is as the SEER is an energy efficiency rating applied to air conditioners.
Split System: Involving an indoor unit, outdoor unit, and a thermostat, the split system is a heating and cooling system.
Thermostat: A necessary part of the HVAC system; the thermostat is a device that monitors, controls, and adjusts heating and cooling equipment.
Two-Stage Operation: For enhanced temperature control, energy efficiency, and indoor air quality, the two-stage operation provides 2 levels of heating or cooling output.
Variable Speed Motor: The variable speed motor operates on a wide range of speeds to precisely control the distribution of heated and cooled air throughout the building.
Ventilator: The ventilator exchanges the stale and re-circulated indoor air with fresh, filtered outside air.
Zoning System: A more customized option; the zoning system controls temperatures in the different zones throughout the home for increased comfort and efficiency to the heating and cooling system.
