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.
What Do Heating and Air Conditioning Installers and Repairers Do?
Heating, air conditioning, and refrigeration mechanics and installers typically do the following:
- Install, clean, and maintain HVACR systems
- Install electrical components and wiring
- Inspect and test HVACR systems and components
- Discuss system malfunctions with customers
- Repair or replace worn or defective parts
- Recommend maintenance to improve system performance
- Keep records of work performed
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.
Some HVACR technicians specialize in one or more specific aspects of HVACR, such as radiant heating systems, solar panels, testing and balancing, or commercial refrigeration.
When installing or repairing air conditioning and refrigeration systems, technicians must follow government regulations regarding the conservation, recovery, and recycling of refrigerants. The regulations include those concerning the proper handling and disposal of fluids and pressurized gases.
Some HVACR technicians sell service contracts to their clients, providing periodic maintenance of heating and cooling systems. The service usually includes inspecting the system, cleaning ducts, replacing filters, and checking refrigerant levels.
Other workers sometimes help HVACR technicians install or repair cooling and heating systems. For example, on a large air conditioning installation job, especially one in which workers are covered by union contracts, ductwork may be installed by sheet metal workers, electrical work by electricians, and pipework by plumbers, pipefitters, and steamfitters. Boiler systems are sometimes installed by a boilermaker.
Home appliance repairers usually service window air conditioners and household refrigerators.
Very simply, Heating and Air Conditioning Installers and Repairers install, service, or repair heating and air conditioning systems in residences or commercial establishments.
(Other job titles in this sub-sector may include: Air Conditioning Technician; Heating, Ventilation, Air Conditioning Installer; Heating, Ventilation, Air Conditioning Mechanic; Heating, Ventilation, Air Conditioning Service Technician; Heating, Ventilation, and Air Conditioning Specialist; Heating, Ventilation, Air Conditioning Technician; Heating, Ventilation, and Air Conditioning Technician); Service Technician; Systems Mechanic)
Heating and Air Conditioning Installers and Repairers typically do the following:
- Test pipe or tubing joints or connections for leaks, using pressure gauge or soap-and-water solution.
- Test electrical circuits or components for continuity, using electrical test equipment.
- Repair or replace defective equipment, components, or wiring.
- Discuss heating or cooling system malfunctions with users to isolate problems or to verify that repairs corrected malfunctions.
- Repair or service heating, ventilating, and air conditioning (HVAC) systems to improve efficiency, such as by changing filters, cleaning ducts, or refilling non-toxic refrigerants.
- Install, connect, or adjust thermostats, humidistats, or timers.
- Connect heating or air conditioning equipment to fuel, water, or refrigerant source to form complete circuit.
- Study blueprints, design specifications, or manufacturers' recommendations to ascertain the configuration of heating or cooling equipment components and to ensure the proper installation of components.
- Comply with all applicable standards, policies, or procedures, such as safety procedures or the maintenance of a clean work area.
- Install auxiliary components to heating or cooling equipment, such as expansion or discharge valves, air ducts, pipes, blowers, dampers, flues, or stokers.
Education and Experience
HVACR systems have become increasingly complex. Therefore, employers generally prefer applicants with postsecondary education or those who have completed an apprenticeship. Some states and localities may require technicians to be licensed. The U.S. Environmental Protection Agency (EPA) requires all technicians who buy, handle, or work with refrigerants to be certified in proper refrigerant handling. Many trade schools, unions, and employer associations offer training programs designed to prepare students for the EPA certification exam.
- Annual pay: In 2019, Heating and Air Conditioning Installers and Repairers earned an average salary of $49,000
- Employment of commercial and residential electricians is projected to grow 13 percent from 2018 to 2028. Commercial and residential building construction is expected to drive employment growth. The growing number of sophisticated climate-control systems is also expected to increase demand for qualified HVACR technicians.
- Entry-level education: Post-secondary education and/or an apprenticeship
