HVAC Mechanics & Installers

Customer service
Be a people person
HVACR technicians often work in customers’ homes or business offices, so it is important that they be friendly, polite, and punctual. Repair technicians sometimes must deal with unhappy customers whose heating or air conditioning is not working.
Detail oriented
Sweat the small stuff
HVACR technicians must carefully maintain records of all work performed. The records must include the nature of the work performed and the time it took, as well as list specific parts and equipment that were used.
Math skills
Numbers matter
HVACR technicians need to calculate the correct load requirements to ensure that the HVACR equipment properly heats or cools the space required.

Job Description

Heating, air conditioning, and refrigeration mechanics and installers—often called HVACR technicians—work on heating, ventilation, cooling, and refrigeration systems that control the temperature and air quality in buildings.

Heating, air conditioning, and refrigeration mechanics and installers typically do the following:

  • Use blueprins to install or repair systems
  • Connect systems to fuel and water supply lines
  • Install electrical wiring and controls
  • Inspect and maintain customers’ systems
  • Test components to determine repairs
  • Repair or replace worn or defective parts
  • Determine HVACR systems’ energy use

Heating and air-conditioning systems control the temperature, humidity, and overall air quality in homes, businesses, and other buildings. By providing a climate controlled environment, refrigeration systems make it possible to store and transport food, medicine, and other perishable items.

Although HVACR technicians are trained to install, maintain, and repair heating, air conditioning, and refrigeration systems, many focus their work on installation, maintenance, or repair. Some technicians specialize in one or more specific aspects of HVACR, such as radiant heating systems, solar panels, testing, and balancing, or commercial refrigeration.
