Below we will define other terms you will hear in the HVAC industry to help make you a more educated consumer.

Efficiency Terms

In 1992, the Federal Government established minimum efficiency requirements for all heating and air conditioning equipment.
If your present HVAC equipment; a furnace, heat pump, or air conditioning system was purchased and installed before that date, it could be highly inefficient by today's standards.

Efficiency ratings are important to understand because installing a new unit could achieve significant energy cost reductions. And that could save you from the higher operating expenses of some pre-1992 equipment.

Air Handler: The portion of a central air conditioning or heat pump system that moves heated or cooled air throughout a home's ductwork.
In some systems, a furnace handles this function.

Heat Source: A body of air or liquid from which heat is collected. In an air source heat pump, the air outside the house is used as the heat source during the heating cycle.

Indoor Coil: The portion of a heat pump or central air conditioning system that is located in the house and functions as the heat transfer point for warming or cooling indoor air.

Outdoor Coil/Condensing Unit: The portion of a heat pump or central air conditioning system that is located outside the home and functions as a heat transfer point for collecting heat from or dispelling heat to the outside air.

Single Package: A year 'round heating and air conditioning system that has all the components completely encased in one unit outside the home.

Split System: A heat pump or central air conditioning system with components located both inside and outside of a building -- the most common types installed in homes.

Supplementary Heat: The auxiliary or emergency heat provided at temperatures below a heat pump's balance point. It is usually Electrical Resistance heat (aka the Heater Package).
But supplemental heat can also be gas or oil-fired equipment.

Zone: A Zone is the area that one thermostat is controlling.

For example: A two story house with a thermostat on each floor has two zones, one for each floor.
