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 "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).

A furnace is a device used for high-temperature heating.

The name derives from Latin word fornax, which means oven.

The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces.

A house is a building that functions as a home.

They can range from simple dwellings such as rudimentary huts of nomadic tribes and the improvised shacks in shantytowns to complex, fixed structures of wood, brick, concrete or other materials containing plumbing, ventilation, and electrical systems.

Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space.

Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers.

Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room.

A house may have a separate dining room, or the eating area may be integrated into another room.

Some large houses in North America have a recreation room.

In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock (like cattle) may share part of the house with humans.

The social unit that lives in a house is known as a household.

The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, governmental, and residential installations.

Over time, this has come to often include both scheduled and preventive maintenance as cost-effective practices to keep equipment ready for operation at the utilization stage of a system lifecycle.

The ampere (symbol: A), often shortened to "amp", is the base unit of electric current in the International System of Units (SI).

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