What is an HVAC Technician?

Before signing up for HVAC classes, it is important for you to understand what it means to become an HVAC technician. HVAC stands for heating, ventilation, and air conditioning. HVAC Technicians also work on refrigeration systems1.

These techs are installing, maintaining, inspecting, troubleshooting, and repairing/replacing HVAC equipment. When you become an HVAC tech, you are an essential worker in the community. Unpredictable weather conditions can disrupt heating and cooling systems in homes, offices, and other buildings. HVAC technicians ensure a comfortable living environment for each client they work with.

What are the HVAC duties and responsibilities?

The tasks that HVAC Technicians perform are essential. Some of the HVAC Technician duties and responsibilities on the job include:

  • 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 performed1

These duties and responsibilities are not skills that come naturally, which is why HVAC training programs are so important. Students must learn and be able to accomplish these tasks to be successful as an HVAC Technician.

Why Should I Sign up for an HVAC Program?

There are many reasons why you should consider receiving an HVAC technician diploma. First, this isn’t a 9-5 office job where you are sitting, doing the same tasks every day. As an HVAC Technician, you will have the opportunity to work in many different locations and perform different HVAC skills and tasks. HVACR technicians work mostly in homes, schools, stores, hospitals, office buildings, or factories.

Some technicians are assigned to specific job sites at the beginning of each day and spend the day there. Others travel to several different places, making service calls for more than one location2. This is a great job for someone who wants to be active at work.

Second, you don’t have to be in school for years. To become an HVAC Tech, some programs take as little as nine months to complete. Spending less time in school means you can complete your training and get started in your career sooner! No matter what the heating and cooling issue is, an HVAC technician is just one call away from helping.

Positive Career Outlook

There’s nothing better than knowing you’re entering a field that is in demand and has a positive career outlook.  According to the bureau of labor statistics, the Employment of heating, air conditioning, and refrigeration mechanics and installers is projected to grow 4% from 2019 to 20293.

In addition, according to the State of Michigan DTMB, Bureau of Labor Market Information and Strategic Initiatives, employment of heating, air-conditioning, and refrigeration mechanics and installers (positions that can be filled by HVAC Systems Technician graduates) are projected to grow 8% from 2018 to 20284. People are always needing to upgrade, maintain, and repair these systems! For this reason, HVAC technicians tend to be busier during the summer and winter months. When heaters and air conditioners are constantly needing to be fixed, there will always be a need to perform HVAC duties and responsibilities!
