A/C (Air Conditioning)

What is A/C (Air Conditioning)?

A/C (Air Conditioning): A construction term referring to systems that control air temperature and humidity within buildings.

Description

A/C (Air Conditioning) is a commonly used term in the construction industry. Air conditioning systems regulate indoor air temperature, humidity, and air quality. These systems are essential in residential, commercial, and industrial buildings to ensure comfort, energy efficiency, and compliance with environmental standards. HVAC (Heating, Ventilation, and Air Conditioning) contractors are responsible for designing and installing A/C units during the MEP (Mechanical, Electrical, and Plumbing) phase of construction. A/C systems range from split units and central air to ductless mini-splits and VRF systems. Proper A/C design impacts energy use, occupant comfort, and long-term maintenance costs.
