Air conditioning, abbreviated as AC, is a technology designed to alter the properties of air (primarily temperature and humidity) to more comfortable conditions. By removing heat from the interior of an occupied space to improve the comfort of occupants, air conditioning units are essential in residential, commercial, and industrial settings for not only comfort but also to maintain the quality of air, preserve goods, and prevent equipment overheating.

What does AC mean in HVAC?
AC stands for air conditioning. It is the system that cools and dehumidifies indoor air by removing heat and circulating conditioned air back into your home or building.

How an AC system pulls in warm air, removes heat, and delivers cool air.
In hot summer months, the AC unit in your home works to lower indoor temperatures, creating a comfortable sanctuary from the heat. In office buildings, AC maintains pleasant conditions for productivity.
Regularly replace or clean your AC unit's air filters to ensure efficient operation and maintain indoor air quality. This simple maintenance task can reduce energy use and extend the lifespan of your unit.
“Regularly replace or clean your AC unit's air filters to ensure efficient operation and maintain indoor air quality. This simple maintenance task can reduce energy use and extend the lifespan of your unit.”
The concept of air conditioning was first developed in 1902 by Willis Haviland Carrier to control humidity in a printing plant.
How does an air conditioner cool your home?
An AC system pulls warm indoor air across the evaporator coil, where refrigerant absorbs heat and humidity. The heat is then released outdoors through the condenser, and the cooled air is circulated back inside.
How often should I service my AC system?
Schedule professional maintenance at least once per year, ideally before the hottest months. Regular tune-ups improve efficiency, reduce breakdown risk, and protect your warranty.
Why is my AC running but not cooling?
Common causes include dirty filters, low refrigerant, frozen coils, or thermostat issues. If basic troubleshooting does not help, a technician can diagnose and fix the root problem.
