What a HVAC System Does

Understanding what an HVAC system is and what it does is the key to getting the most out of the HVAC system in your home. HVAC is an acronym that stands for Heating, Ventilation, Air Conditioning.

How Does an HVAC System Work?

An HVAC system uses refrigerant evaporation in order to provide air conditioning and cooling. An HVAC system will also provide heating through the exact same ventilation system, but it will rely on a heat pump or a furnace in order to do this. An HVAC system is simply a central system that works to provide air conditioning and heating through a single ventilation system.

Types of HVAC Systems

There are actually four different types of HVAC systems that are used in commercial and residential constructions.

Furnace and Condensing HVAC Systems pull air in from the outside, replacing the inside air with fresh air and dispelling the polluted air out.

Heat Pump and Fan Coin HVAC Systems pull air in from the outside but the heating and cooling functions are both performed using a heat pump.

Zoning HVAC Systems break the home into zones, each possessing its own thermostat control.

Packaged HVAC Systems combine the elements of fan and heat pump systems together.

Each of these different types of HVAC systems works in a different way depending on the construction of the system and the application that the system is being used for. Some of these HVAC systems break the property up into different segments while others address the heating and cooling needs of a building all at once.
