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).

Plumbing is any system that conveys fluids for a wide range of applications.

Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.

Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications.

The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

Valves are technically fittings, but are usually discussed as a separate category.

In an open valve, fluid flows in a direction from higher pressure to lower pressure.

The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

The ampere (SI unit symbol: A, dimension symbol: I), often shortened to "amp", is a unit of electric current.

In the International System of Units (SI) the ampere is one of the seven SI base units.

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

In business, engineering and manufacturing, quality has a pragmatic interpretation as the non-inferiority or superiority of something; it's also defined as fitness for purpose.

Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood differently by different people.

Consumers may focus on the specification quality of a product/service, or how it compares to competitors in the marketplace.

Producers might measure the conformance quality, or degree to which the product/service was produced correctly.
