Air Diffuser: A point of distribution where room air is mixed with cooled air-conditioned air. Air diffusers are usually covered with a grille/vent plate and located along the ceiling or floor.
Blower: Also known as an ‘air handler’, this is a fan that forcibly propels cooled air throughout the ductwork and towards the air diffusers.
Condenser Coil: This coil is where refrigerant is condensed into a liquid, releasing heat from the system and cooling the air.
Controller: Also known as a thermostat
Dual Duct System: A type of climate control system utilizing two ducts, one with cool air and one with warm air. Mixing of these two airflows is done in a manner that achieved desired room temperatures.
Freon: A type of refrigerant made from chlorofluorocarbon gas.
Heat Pump: An outdoor unit capable of producing both cool and heat, often ideal for mild climates.
R-22 Refrigerant: An old standard of refrigerant no longer in use and progressively being phased out for R-410A.
R-410A Refrigerant: A chlorine-free refrigerant considered to be more environmentally friendly than its R-22 predecessor.
Seasonal Energy Efficiency Ratio (SEER): A measure of energy efficiency that calculates the average amount of BTUs generated for every ‘watt-hour’ of energy used.
Temperature Zones: Segregated areas, often individual rooms, located in a home or business where temperature can be independently controlled or adjusted.
