What do HVAC Technicians Do?

It’s safe to say that HVAC systems and the technicians who work on and install them – have made the world a much more comfortable place. After all, in the blazing heat of summer, can you imagine a world without the cooling comfort of an air conditioner? It’s equally hard to imagine living without the warmth of central heat and air during a frosty winter. But what exactly does an HVAC technician do and is a career in the HVAC industry worth pursuing? To answer those questions, let’s start by exploring what an HVAC technician does on a routine basis.

What is HVAC?

Heating, ventilation and air conditioning. The system that heats, cools and controls the air quality and temperature in buildings. The HVAC industry also includes the refrigeration systems that keep perishables and things like vaccines and other medical supplies – fresh and safe.

Types of HVAC Systems and Certifications

The type of HVAC system being used in a particular building or home can vary. And depending on what type of system it is, you’ll need the proper EPA Certification to work on that system. These certifications are obtained through NATE, or North American Technician Excellence; the non-profit organization made of industry experts who administer the tests for HVAC certifications. There are 3 different EPA levels of certification in the HVAC industry:

1. Type I EPA Certification

This certification covers the repair and maintenance of small HVAC appliances. This would include things like window A/C units and residential refrigerators and freezers.

2. Type II EPA Certification

This level is for larger appliances that operate at high pressure. It would include things like outdoor A/C units and commercial refrigerators.

3. Type III EPA Certification

Low-pressure systems that do not fit under the small appliance category are covered by this certification.

If you obtain all 3 certifications, you are considered – universally certified and can work on – all of the systems above.

How Do You Become an HVAC Technician?

An easy way to become an HVAC technician is to attend a program at a vocational school. You can train to become an HVAC technician in months, rather than years. This only briefly keeps you out of the job market and returns you back to earning in less time than a 2-year or 4-year college. Vocational schools even offer flexible schedules with day and evening schedules so you can keep that job to pay the bills or take care of a family member.

What are the Benefits of Attending a Vocational School?

In addition to the quick start that you will get by attending a vocational school, rather than a 2-year or 4-year college, you will enjoy guidance from industry experienced instructors. These instructions have experience in their given vocation and know what you need to succeed in your new craft. They offer one-on-one attention, so no one is left behind.

Small class sizes mean you get direct contact and instruction from faculty rather than sit in a large lecture hall and become a number rather than a name. Small classes also allow you to get to know your classmates and network with them throughout your career. You never know when you will need help filling a job gap or find an opportunity to advance in your career.

The best benefit of attending a vocational school is the career services that they offer. From resume building, mock interviews, thank you email writing and job fairs, and everything in between, you get expert advice to prepare you for the job hunt. Career services also has strong ties with the community and may even hear about an opportunity even before the general public. Employers know that vocational school graduates are well informed and ready to hit the ground running.
