AFUE – Annual Fuel Utilization Eciency. The AFUE percentage tells you how much energy is being converted to heat. The higher the number the greater the eciency.
AIR HANDLER – The portion of your heating and cooling system that forces air through your home’s ductwork.
BTU – British Thermal Units. The amount of heat it takes to raise one pound of water one degree Fahrenheit. The higher the BTU rating, the larger the heating capacity of the furnace or air
CAPACITY – The ability of a heating or cooling system to heat or cool a given amount of space. Heating is usually expressed in BTUs, cooling is expressed in tons.
COMPRESSOR – The motor/pump that drives the air conditioning unit. It is responsible for pumping refrigerant throughout the system.
CONDENSER COIL – Part of the outdoor portion of a heating or cooling system, that releases or collects heat from the outside air.
DAMPER – A valve or moveable plate used in duct work that opens and closes to control airow. They are used to direct air to specic areas of the home.
DOWNFLOW – A type of furnace that takes cool air from the top and blows warm air to the bottom.
DUCTWORK – Hollow metal pipes used to transfer air throughout your house.
ECOLOGIC – Maytag’s designation of green heating and cooling equipment.
ELECTRONIC AIR CLEANER – An electronic device that lters out particles and contaminants in indoor air.
EVAPORATOR COIL – Part of the heating or cooling system located indoors, that cools and dehumidies the air by converting liquid refrigerant into gas.
HEAT EXCHANGER – The major part of the furnace that transfers heat into your home.
HEAT PUMP – A unit that handles both heating and cooling. In some climates, a heat pump may handle your heating and cooling needs more eciently than a furnace and air conditioner.
HORIZONTAL FLOW – A type of furnace, installed on its side, which draws air from one side, heats the air and then sends it our the other side.
HSPF – Heating Seasonal Performance Factor. Measures the heating eciency of a heat pump. The higher the number the more ecient the heat pump heats your home.
HUMIDIFIER – A piece of equipment that adds moisture to the air as it comes out of the furnace.
HVAC – Heating, Ventilation and Air Conditioning
REFRIGERANT – A chemical that cools air as it evaporates.
SEER – Seasonal Energy Eciency Rating. SEER measures a unit’s cooling eciency. The higher the number, the greater the eciency.
SINGLE PACKAGE – An outdoor unit that contains both a heating and a cooling system.
SPLIT SYSTEM – Refers to an air conditioner or heat pump that is combined with indoor components, such as an evaporator coil inside and a condenser coil outside your home.
THERMOSTAT – A device that monitors and controls your temperature inside your home.
UPFLOW – A type of furnace that draws cool air from the bottom and blows the warmed air out the top.
VENTILATOR – A ventilator captures heating or cooling energy from stale indoor air and transfers it to fresh incoming air.
ZONE – Zoning allows you to control the heating and cooling delivered to specic areas of your house for a custom solution.Zoning can increase eciency and comfort in the areas of the
house you use most often.
