A heating, ventilation, and air conditioning (HVAC) controls technician installs, calibrates, and repairs HVAC equipment to maintain proper environmental conditions in a building. In the construction of new homes, offices, and industrial facilities, the HVAC controls technician interacts with a variety of clients and collaborates with other skilled trades. A HVAC controls technician typically works in environments with dust, fumes, temperature extremes, and high noise levels. Most employers prefer candidates who have completed an accredited HVAC program and have worked as an HVAC control technician for at least two years.
An HVAC controls technician’s primary responsibility is to install, repair, and maintain control systems. The HVAC controls technician arrives at the job site after receiving a work order to inspect the equipment. To determine the problem and find a suitable solution, a series of diagnostic tests are carried out. To properly adjust pneumatic control systems, this entails reading control logic diagrams and wiring schematics. All of the temperature, humidity, and pressure readings have been calibrated and tested.
HVAC controls technicians also repair and maintain the HVAC system in addition to the control systems. Pumps, motors, an air compressor, and fans are all included. If these parts are worn out, they are replaced; if they are still serviceable, they are greased and adjusted. Valve and belt drives are also inspected and maintained.
HVAC controls technicians are responsible for replacing outdated and inefficient systems with newer technologies as they become available in order to reduce costs and improve building environmental conditions. While the HVAC system is being serviced, technicians work with clients to coordinate activities to ensure the safety of those who work or live in the building. In addition, technicians make suggestions for improving the HVAC system.
There are administrative responsibilities in addition to the service component of the job. This usually entails preparing accurate cost estimates for a specific repair job as well as keeping track of all inspections and equipment replacements. HVAC technicians can also hire out labor for large jobs. This entails negotiating compensation and delegating responsibilities in order to complete the project on time and on budget. In addition, the technician ensures that equipment inventory is maintained and that specialized parts are obtained from vendors.
Other employees are trained on how to operate and maintain HVAC equipment by an HVAC controls technician. More senior technicians are usually in charge of training new employees. Younger recruits are taught protocols and procedures, as well as trade secrets.
