Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort.

Its goal is to provide thermal comfort and acceptable indoor air quality.

HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

In physics, energy is the property that must be to an object in order to perform work on – or to heat – the object, and can be converted in form, but not created or destroyed.

The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton.

Every decision-making process produces a final choice; it may or may not prompt action.

Decision-making is the process of identifying and choosing alternatives based on the values and preferences of the decision-maker.

A system is a set of interacting or interdependent component parts forming a complex or intricate whole.
