What is the difference between HVAC and AC? Acronyms in the construction industry can confuse building owners and others who are looking to upgrade or install mechanical systems in their facility.  Let’s get back to the HVAC basics.

HVAC is an acronym that stands for heating, ventilation, and air conditioning. This means that the mechanical system provides comfortable, safe indoor air quality for a building. The design of a heating and cooling mechanical system can be complex or simple, depending on the mechanical engineering and building specifications. This mechanical system is an integral part of heating and cooling any modern building. AC is short for air conditioning. The terms HVAC and AC are often used interchangeably.
