What Does an HVAC Technician Do?

Usually, HVAC technicians start their day by going through all the jobs they need to perform, which are scheduled for that specific day. They may need to repair a flawed system to make sure it works properly, or advise the owner to replace their HVAC, or install a new one at someplace. Here are three of the primary tasks that an HVAC technician does on a typical day.


In order to make sure the effectiveness and safety of the HVAC systems, it’s important that only a professional and licensed technician installs them. That’s because a trained and qualified technician understands the requirements of both commercial and residential areas and installs the right size system. It won’t be possible for any other person to determine the correct information. That’s because performing the necessary calculations in this regard is too technical to be done by someone who isn’t a professional. Moreover, the HVAC technician will also connect the system to electrical wiring, air ducts, fuel lines, water lines, and more to make sure that it works perfectly.

HVAC technicians also perform repairs, which they first need to identify by performing necessary troubleshooting. The problem can reside anywhere from air handling system and refrigerant levels to compressors, or the thermostat to the HVAC unit itself. A professional knows how the whole system and each individual unit works and how to perform HVAC repair correctly.
