    Common Heating and Cooling system components

    Air conditioner

    Also known as a condenser, this exterior unit is paired with a coil (also known as an evaporator) to comprise the system that cools the air in your building.

    Furnace

    This interior unit heats and circulates air throughout a structure’s ducts.

    Thermostat

    This is the temperature control center of your heating and cooling system.

    Components that improve Indoor Air Quality

    Germicidal UV Light

    Uses UV (See Terms to know) technology to continuously sterilize and purify the indoor air you breathe and significantly reduce environmental stresses to your immune system.

    Central Humidifier

    Maintains the proper level of moisture in your building, which reduces static electricity and helps you feel warmer in winter and more comfortable year round.

    Energy Recovery Ventilator

    An indoor air quality component that brings fresh outside air into your space while expelling stale air.

    Electronic Air Cleaner

    Additional filtration intended to reduce airborne allergens, providing better air to breathe.

    Know your HVAC Terminology

    AFUE

    Annual Fuel Utilization Efficiency. Measures a gas furnace’s efficiency. T he higher the AFUE rating, the more efficient the unit.

    BTU

    British Thermal U nit. Represents the measure of heat given off when fuel is burned for heating.

    Capacity

    Refers to a unit’s ability to cool or heat a space. Usually measured in BTU s or tons.

    Condenser

    In an air conditioning system, it dissipates heat from the refrigerant, changing the refrigerant from vapor to liquid. In a heat pump system, the coil absorbs heat from the outdoors in the heating mode.

    Ducts

    The pipes or channels that carry air throughout the home.

    HS PF

    Heating Seasonal Performance Factor. Measures the heating efficiency of a heat pump. T he higher the number, the more efficient the unit.

    HVAC

    Heating Ventilating and Air Conditioning.

    MERV

    Minimum Efficiency Reporting Value. Measures efficiency of air filters.

    Refrigerant

    A chemical that produces a cooling effect.

    Refrigerant Reclaim

    The act of processing used refrigerant gas which has previously been used in some type of cooling loop such that it meets specifications for new refrigerant gas. In the United States, the Clean Air Act of 1990 requires that used refrigerant be processed by a certified reclaimer, which must be licensed by the United States Environmental Protection Agency (EPA), and the material must be recovered and delivered to the reclaimer by EPA-certified technicians.

    SEER

    Seasonal Energy Efficiency Ratio. Measures cooling efficiency in air conditioners and heat pumps. The higher the SEER, the more efficient the unit.

    Thermostat

    The control center of a heating and cooling system.

    Ton

    Unit of measurement used for determining cooling capacity. One ton equals 12,000 BTU s per hour.

    UV

    Ultraviolet. Ultraviolet light is high-frequency light above the visible spectrum.

    Zoning

    Method of dividing a building into different areas or zones that can be independently controlled.
