Become HVAC Savvy in 2018

Like any technology, there are terms in the HVAC industry that are worth knowing as an owner of an HVAC system. Scroll down this page to find the technical definitions of some of the most common terms used when referring to home comfort systems.

AFUE

Annual Fuel Utilization Efficiency. This is a measure of a furnace’s heating efficiency. The higher the AFUE percentage is, the greater the efficiency.

Air Handler

This is the part of your HVAC system that pushes heated or cooled air throughout your home’s ductwork.

Balance Point

The temperature at which a heat pump’s output equals the heating needs of the home, typically between 30 and 45 degrees Fahrenheit. If the temperature is below the balance point, supplementary heat is required to sustain a stable indoor temperature.

Btu

British thermal unit. This is the amount of heat required to raise the temperature of one pound of water by one-degree Fahrenheit.

Compressor

This pump is in many ways the heart of an HVAC system. The compressor moves refrigerant from the evaporator coil to the outdoor condensing unit and back to the evaporator.

Evaporator Coil

The part of the heat pump or air conditioning system located in the home and functions as the heat transfer for heating or cooling indoor air.

Heat Pump

An air conditioner with a valve that can alternate between heating and cooling.

HSPF

Heating Seasonal Performance Factor. This is a measurement of the heat pump’s efficiency. The higher the HSPF, the greater the efficiency.

SEER

Seasonal Energy Efficiency Ratio. This is a measurement of an air conditioner’s cooling efficiency. Units with higher SEER ratings have greater efficiency.

Split System

An HVAC system with components located both inside and outside the home.
