Glossary Of Air Conditioning Terms & Definitions

Air Handler: Air handler also referred to as the coil boiler, is the indoor part of an air conditioner or heat pump that circulates cooled or heated air throughout the ductwork of your home or business.
Air-Conditioning and Refrigeration Institute (ARI): An industry trade association that develops the standards for measuring and certifying product performance.
Bioaerosols: Microscopic living organisms suspended in the air. Bioaerosols grow and multiply in warm, humid places.
British Thermal Unit (BTU): The BTU is a measurement of heat energy. To raise one pound of water by one degree Fahrenheit, requires one BTU of heat. The greater the heating capacity of the system reflects a high BTU rating.
Carbon Monoxide: An odorless, colorless, tasteless, poisonous and flammable gas produced when carbon burns with insufficient air. It can be very harmful to people and pets.
Central Air-Conditioning System: System in which air is cooled at a central location and distributed to and from rooms with the use of one or multiple fans through a series of ducts.
Communication Module: A component of a SunSource® Home Energy System that shows system status and environmental benefits in real time.
Composite Fan Blades: Blades that are designed with rugged materials and an exclusive angled design that improve operation and durability, even in the harshest environments.
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 or sometimes known as an outdoor coil is the compressor is an outdoor 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 how many cubic feet of air pass by a stationary point in one minute. The more air being moved through the ductwork by the system, the higher the number is to the CFM.
Damper: Located in the ductwork is a moveable plate that regulates airflow and directs it to areas that need it most, which is typically used in zoning application.
Decibel (DB): A unit used to measure the relative intensity of sound.
Department Of Energy (DOE): A federal agency responsible for 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. Dry-charged units are appropriate for homeowners who need a replacement unit compatible with R-22 refrigerant.
Ductwork: The method by which air is channeled from the furnace or the blower coil throughout your home.
Electronic Air Cleaner: An electronic device that filters out large particulates and bioaerosols in indoor air.
Energy Star: A designation of the U.S. Environmental Protection Agency (EPA) to which the Energy Star is attached to HVAC products that meet or exceed federal guidelines for energy-efficient performance.
Environmental Protection Agency (EPA): An agency of the U.S. government that develops and enforces federal environmental regulations and oversees the nationwide ENERGY STAR® program.
Evaporator Coil: The evaporator coil or sometimes referred to as an indoor coil is the part of an air conditioner or heat pump that absorbs the heat from the air. It is either assembled inside the air handler or attached to the furnace.
Garage Heaters: Natural or propane gas units that provide warmth for car garages of almost any size during the winter months. Separated combustion models provide heating for hard-to-heat applications.
Grid-Tied System: The most common and least expensive of all residential solar systems. Allows homeowners to use their own solar-generated electricity to save energy and reduce costs. The utility company’s grid, or network of power stations, serves as the backup power source.
Heat Pump: In the summer, it reverses the process and 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.
Humidistat: An automatic device used to maintain humidity at a fixed or adjustable set point.
HVAC: Heating, Ventilation and Air Conditioning system.
ISO 9000: A family of international standards for quality management and assurance.
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 entails that the holes in the filter are smaller suggesting a higher the efficiency.
Micron: A unit of measure equal to one millionth of a meter, or one thousandth of a millimeter.
Packaged Unit: A packaged unit is a heating and cooling system contained in one outdoor unit.
Particles: Any substances measuring less than 100 microns in diameter. The U.S. EPA has found that particles less than 2.5 microns are responsible for the health effects of greatest concern.
Programmable Thermostat: A thermostat with the ability to record different temperature and time settings for home heating and/or cooling equipment.
R-22 Refrigerant: The old standard for residential air conditioners, now being phased out by the U.S. EPA.
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. Generally, residential air conditioning units contain the standard R-22 refrigerant, or Freon.
Refrigerant Lines: Refrigerant lines are two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil.
Scroll Compressor: A specially designed compressor that works in a circular motion, as opposed to up-and-down piston action as the more traditional design.
Seasonal Energy Efficiency Ratio (SEER): Seasonal Energy Efficiency Ratio is an energy efficiency rating for air conditioners, the higher the SEER, the more efficient the unit is.
Split System: A heating and cooling system that includes an indoor unit, outdoor unit and a thermostat.
Thermidistat: A unit that monitors temperature and humidity and adjusts heating or cooling system to maintain desired levels.
Thermostat: A unit that allows homeowners to monitor and adjust heating and cooling equipment.
Ton: Unit of measurement for determining cooling capacity. One ton is equal to 12,000 BTUH.
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: A motor that operates at a wide range of speeds to precisely control the distribution of heated and cooled air throughout the home.
Ventilator: A system that exchanges 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.
