What is the job of the HVAC technician?

Let’s look in details at the main tasks that technicians do while on the job.

Installation

Standard procedure requires the technician to install a unit, following the specifications given by an architect. Before doing the installation however, the required calculations must be completed to find out the most suitable system. Upon installation, the technician must now test the connections and pipes and hook up the HVAC unit to the distribution system. It is a requirement that refrigerant technicians are licensed by the Environmental Protection Agency (EPA), and they are responsible for charging the system with refrigerant. See here

Maintenance

All cooling, heating and ventilation systems require regular maintenance checks to ensure optimum perform. These checks are needed biannually, at the start of spring and autumn.  In these maintenance checks the technician usually test and clean the blower fan, check the cooling system’s coolant level and test the thermostat and operation of the system.

Repair

Heating and ventilation systems technicians handle all related problems or issues of the HVAC unit; compressors, refrigerant levels, air control system and the thermostats and other controls.

Ductwork

In work situations where union affiliation is not a problem, the technician can assemble and install the ductwork that circulates the warm or cool air from the system. This involves cutting of metals sheets to make ducts, connecting the ducts to the unit and setting up the ductwork.

There are technicians who sell service contracts to their customers and provide regular maintenance of heating and ventilation systems.  Sometimes other tradespeople work with these technicians to install or repair the systems.

With increasing energy costs, building operators are concerned about energy conservation. This means that these technicians may be required to resolve usage of energy by HVAC/R systems, conduct system upgrade, install green heat pumps or smart thermometers and the checking of the energy usage occasionally.

In addition, all technicians are required to stick to government regulations and local HVAC guidelines in terms of handling, recycling, recovery, conservation and discarding of refrigerants and other fluids. URL: https://en.wikipedia.org/wiki/Heating,_ventilation,_and_air_conditioning

Technicians can also advise customers on how to avoid future problems and how to maintain equipment such as changing filters or oiling parts regularly. Basically, the technician’s main job is preventing problems, help customers save money and keep customers comfortable.
