Details for Heating and Air Conditioning Mechanics and Installers
Install, service, and repair heating and air conditioning systems in residences and commercial establishments.
- 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.
- Lay out and connect electrical wiring between controls and equipment, according to wiring diagrams, using electrician's hand tools.
- Inspect and test systems to verify system compliance with plans and specifications or to detect and locate malfunctions.
- Record and report time, materials, faults, deficiencies, or other unusual occurrences on work orders.
- Install and test automatic, programmable, or wireless thermostats in residential or commercial buildings to minimize energy usage for heating or cooling.
- Adjust system controls to settings recommended by manufacturer to balance system.
- Install dehumidifiers or related equipment for spaces that require cool, dry air to operate efficiently, such as computer rooms.
- Recommend, develop, or perform preventive or general maintenance procedures, such as cleaning, power-washing, or vacuuming equipment, oiling parts, or changing filters.
- Install magnetic-centrifugal chillers, compressors, or related equipment to cool air temperatures through the use of recirculating water.
- Cut or drill holes in floors, walls, or roof to install equipment, using power saws or drills.
- Measure, cut, thread, or bend pipe or tubing, using pipe fitter's tools.
- Install or repair air purification systems, such as specialized filters or ultraviolet (UV) light purification systems.
- Assemble, position, and mount heating or cooling equipment, following blueprints or manufacturer's specifications.
- Fabricate, assemble, or install duct work or chassis parts, using portable metal-working tools or welding equipment.
- Install radiator controls for room-level zone control heating of residential or commercial buildings.
- Install or repair self-contained ground source heat pumps or hybrid ground or air source heat pumps to minimize carbon-based energy consumption and reduce carbon emissions.
- Wrap pipes, securing insulation in place with cement or wire bands.
- Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.
- Investigative - Investigative occupations frequently involve working with ideas, and require an extensive amount of thinking. These occupations can involve searching for facts and figuring out problems mentally.
- Conventional - Conventional occupations frequently involve following set procedures and routines. These occupations can include working with data and details more than with ideas. Usually there is a clear line of authority to follow.
Education, training, experience
- Education - Most occupations in this zone require training in vocational schools, related on-the-job experience, or an associate's degree.
- Training - Employees in these occupations usually need one or two years of training involving both on-the-job experience and informal training with experienced workers. A recognized apprenticeship program may be associated with these occupations.
- Experience - Previous work-related skill, knowledge, or experience is required for these occupations. For example, an electrician must have completed three or four years of apprenticeship or several years of vocational training, and often must have passed a licensing exam, in order to perform the job.
- Sales and Marketing - Knowledge of principles and methods for showing, promoting, and selling products or services. This includes marketing strategy and tactics, product demonstration, sales techniques, and sales control systems.
