What is an HVAC system?

HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling both residential and commercial buildings.

What does an HVAC technician do?

An HVAC or HVACR technician installs, repairs, or maintains heating, ventilation, air conditioning, and refrigeration systems that control the temperature and air quality in buildings. In some cases, an HVAC technician may specialize in installation, repair, or maintenance.

How do I know if I have an HVAC system?

Every heating and cooling system comes with manufacturer and energy guide labels. And sometimes, those labels will tell you what kind of unit you have. For example, walk outside to your condenser and look for a manufacturer label.

How long does an HVAC system last?

In general, most HVAC systems will last from 15 to 25 years, but depending on the type of system and other contributing factors, that estimate can be highly variable.

Should I replace my 20 year old HVAC system?

Yes. If your HVAC is over 20 years old, consider replacing it with a more energy-efficient unit, such as one that has earned the ENERGY STAR label.

Will a new HVAC system reduce my cooling costs?

DoE data suggests that replacing an old air conditioner with a modern, energy-efficient unit can save you up to 40% on cooling costs.
