HVAC system

Indoor air management equipment

An HVAC system is equipment that controls indoor climate—heating, ventilation, and air conditioning.

The term covers everything from residential furnaces and central air units to industrial climate control.

The HVAC system needs servicing before winter.

Building codes specify HVAC requirements for air quality and energy efficiency.
