Part of our job here at Answer Heating and Cooling is to make sure you are educated and can make the right decisions! Here are the definitions for some of the most commonly used terms and phrases in the HVAC world.
The indoor component of your air conditioner or heating system that moves air through your home.
Annualized Fuel Utilization Efficiency (AFUE)
A measure of furnace heating efficiency. The higher the AFUE, the more efficient the furnace.
British Thermal Unit. In scientific terms, it represents the amount of energy required to raise one pound of water one degree Fahrenheit. One BTU is the equivalent of the heat given off by a single wooden kitchen match.
An odorless, colorless, tasteless, poisonous and flammable gas produced when carbon burns with insufficient air.
Central Air-Conditioning System
System in which air is cooled at a central location and distributed to and from rooms by one or more fans and a series of ducts.
Part of the outdoor component to your air conditioning unit that pumps refrigerant. Works to maintain the pressure in your HVAC system to provide adequate cooling to your home.
The outdoor portion of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year.
A Environmental Protection Agency (EPA) program designed to reduce the nation’s energy consumption. ENERGY STAR® -qualified heating equipment can be up to 15 percent more efficient than standard models. ENERGY STAR® -qualified cooling equipment can be up to 7 percent more efficient than minimum-standard equipment.
The part of an air conditioner or heat pump that absorb the heat from the air in your house. It is located inside the air handler or attached to the furnace.

Minimum Efficiency Reporting Value (MERV) is a standard that rates the overall effectiveness of air filters. Higher value MERV rating equates to finer filtration, meaning fewer dust particles and other airborne contaminants can pass through the filter.
North American Technician Excellence. This is the nationwide certification program for home heating and cooling technicians. It’s the only certification that is recognized by the entire industry.
This calculation is the efficiency rating used for central A/C systems as an average over the entire cooling season.The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit’s SEER rating the more energy efficient it is. In the U.S., the SEER is the ratio of cooling in British thermal unit (BTU) to the energy consumed in watt-hours. The coefficient of performance (COP), a more universal unit-less measure of efficiency, is discussed in the following section.
A zoning system sections a building or a space into zones which run independently of each other, each having their own thermostat or control.
