HVAC vs AC Explained
What is the main difference between an HVAC and AC unit?
Today, these two names are used loosely and have almost become one, even though there is a distinct difference. People use the term HVAC System and AC or Air Conditioning System to talk about the equipment that heats and cools their home. However, an AC system Air Conditions only and an HVAC system is the system that Heats, Ventilates and Air Conditions your home.
What is an HVAC unit?
“HVAC” stands for heating, ventilation, and air conditioning. When discussing the components of your home as a whole, you would use the term “HVAC system” because the entire system heats, cools and ventilates the hot or cold air in your home.
When heating and air conditioning professionals talk about “HVAC units,” they are talking about the equipment that does the heating, the cooling, or both (because HVACs do all of these things).
What is an AC unit?
In contrast to the full HVAC unit or HVAC system, an “air conditioning unit” refers exclusively to the system that cools your home. Some contractors use the terms “AC” and “HVAC” interchangeably, which is one reason why homeowners get confused.
When AC systems were first built, they cooled the home and relied on a gas or oil furnace to heat the home. Today, there are several different types of Air Conditioning (AC) systems. These include Air Conditioners which rely on a gas furnace for heat, Heat Pump Systems which have components that can heat your home using only electricity, and Geothermal Systems which use the ground to both heat and cool your home.
