heating, ventilation, and air conditioning
First and foremost, HVAC stands for heating, ventilation, and air conditioning. This system provides heating and cooling to residential and commercial buildings. You can find HVAC systems anywhere from single-family homes to submarines where they provide the means for environmental comfort.
The main purposes of a Heating, Ventilation, and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort.
It uses electricity and coolant liquid to reduce the temperature of the air, while sending hot air outside and cold air inside. Ductwork is the transit system for hot and cold air throughout the home. It moves it throughout the interior of your home. The thermostat acts as the brain of your system.

Air conditioning units generally last around 15 years or so. If you want your air conditioning unit to live as long as possible, you want to get it maintained twice a year. Your AC, like your furnace, should be sized correctly for your home.
The main reason homeowners do not purchase an HVAC service contract is cost.

Geothermal heat pumps are the most efficient home heating system around. If you can afford the installation cost, they can lower your energy bills significantly.
Heating and Air Conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring.
Regular AC maintenance servicing costs $75 to $200 for simple tune ups. Extended service contracts run $150 to $500 but include the entire HVAC system, both heating and cooling. For repairs outside a standard service, expect to pay $50 to $150 per hour for an HVAC technician.
The electric furnace is the second to cheapest option at $3,040 while the electric boiler is the cheapest option at $2,500. Though the gas boiler is most expensive to buy at $3,500, the heat pump has the highest installation cost of $4,000, which nudged it to the top of the pile in terms of overall initial cost.
