Career Overview
What Do HVAC Techs Do?
The responsibilities of an HVAC tech are varied. They must carefully follow specs or blueprints to install and maintain equipment. Workers seal air gaps, affix replacement parts into units, and run tests to ensure systems properly operate. There are times when technicians work after-hours or answer emergency calls in between shifts.
Technicians are in high demand across the country, which means an employee-friendly job market exists for those with passion and the proper skills. Most trade students put their HVAC education to use quickly upon graduation. Prospects should be optimistic while also understanding that there are a lot of rules and details to learn in order for success.
Techs often advise clients on how to best upgrade an old system or improve its efficiency. Professionals must not only be up-to-date on hardware technology, but they need to know about government regulations and laws surrounding the industry.
What Are HVAC Job Duties?
HVAC mechanics interact with customers in many ways. They take phone calls from people having issues with their heating and cooling units. Associates also schedule appointments in order to perform inspections and give cost estimates.
Colleagues are responsible for the installation and repair of electrical wiring, fuel lines, and water supply pipes. They join air ducts with climate control systems and install wall-mounted remotes for temperature adjustment. While connecting, disconnecting, or purging AC units, they must use low-loss fittings to reduce the quantity of refrigerant released.
Other HVAC duties include inspecting home insulation for draft areas and making sure plant growth does not interfere with outdoor units. Techs also replenish refrigerant and replace dirty or aged air filters. They may do yearly checks and cleanings on evaporator coils as well.
HVAC mechanics perform the following tasks:
- Lifting, pushing, and moving objects over 75 pounds
- Using process of elimination to determine issues with heating and cooling units
- Reading through and understanding wiring schematics and electrical ladder diagrams
- Running ducts and piping through crawl spaces, walls, and attics
- Retrofitting old furnaces and AC units with newer models
- Recapturing refrigerant
- Safely disposing of unusable refrigerant
What Types of Rules Surround the Use of Refrigerant?
With the help of compressors and evaporators, refrigerant fluid makes modern refrigeration possible. The liquid is explosive, highly toxic, and a contributor to ozone depletion. Because of this, the EPA has set strict guidelines regarding its use.
Only approved HVAC companies can legally purchase refrigerant. Due to its dangerous nature, technicians must closely follow the EPA standards, as infractions will result in daily fines of over $35k.
Residents should have refrigerant leaks repaired immediately to prevent health effects such as shortness of breath or dizziness. Refrigeration and air conditioning units carry their own unique disposal guidelines due to the toxic chemicals contained within.
Home AC units labeled R22 use particularly dangerous, out-of-date refrigerants. While it’s not required by law to upgrade to a modern R410A system, doing so results in cleaner air quality and decreased energy consumption.
What's It like near an HVAC Tech's Workspace?
Even though HVAC techs visit a variety of job sites, the working conditions are largely similar. Associates find themselves in dirty, cramped areas of buildings, such as crawl spaces and wall voids. These places are often dusty and moldy, containing bugs, spider webs, and exposed nail or screw points.
Technicians maneuver and perform dangerous actions while in dark places like attics and boiler rooms. When team members service broken units, HVAC equipment isn’t regulating air temperature, meaning extreme hot or cold conditions for workers.
Why Do HVAC Technicians Need People Skills?
HVAC techs are always meeting new people at a diverse range of job sites. In order to put customers at ease, associates should be friendly and considerate. Lack of eye contact, disinterest, or pushy sales tactics annoy clients and discourage repeat business.
Team members work with a wide variety of complex equipment. At times, they may explain to colleagues how to use these tools. Since improper use can lead to serious injury, good communication skills and thorough explanations are vital.
When appropriate, HVAC techs may upsell customers on add-ons and enhancements. Workers must remain friendly and approachable even if called into emergency jobs during off-hours. There might be instances where technicians need to collect money from previous clients behind on their payments.
What Are Useful Skills and Traits for People in This Field?

How Do HVAC Requirements Affect Students?
On-the-job training is common, however trade programs or other HVAC classes can give prospects an advantage. Certificates from reputable institutions are often enough to land jobs. However, employers especially appreciate applicants that have associate’s degrees or higher. Bachelor’s HVAC degrees are held by just over 5% of technicians.
Graduation from an accredited HVAC school takes about a year or two. While certificate courses may cost around $1k, an associate’s degree program can carry a price tag upwards of $35k. Those with formal schooling regularly earn more than those without.
Some employers require pre-employment background checks or drug tests before hiring. Others even ask prospects to show proof of apprenticeship training on their HVAC resume. In order to get hired, hopefuls might need to possess valid driver’s licenses and pass basic math tests.
Many companies will provide HVAC training and education to inexperienced new hires. This is due to the high demand for workers in the industry. However, recruits with some prior knowledge usually get jobs over those with zero HVAC skills. In certain states, prospects need a special license to work legally.

A HVAC certificate can even lead to a career as a solar panel installer. These workers prepare installation sites, deploy underground wiring, and create foundations. They also assemble support equipment like mounts or racks, and troubleshoot when issues arise. With today’s eco-minded outlook, solar panel installers are more in-demand than ever.
What Does It Take to Be an HVAC Engineer?
The responsibilities of an HVAC engineer are fit for someone with experience in the field. These workers differ from techs and installers in that they oversee and coordinate operations on worksites. They concoct solutions for difficult problems and design blueprints for customized systems.
Interview with an HVAC Specialist
Q&A session with Jerry O., a HVAC specialist who owns his own heating and air company in Houston, Texas.
Q: How long have you been a HVAC specialist?
A: I have been in the business for 25 years, but I didn’t start my own business until 10 years ago. Before that, I worked for a few different heating and air companies. Part of that time I was working as an apprentice.
Q: What type of training did you have to become a HVAC specialist?
A: The only training I had at first was my apprenticeship. Back when I got started, that was really the only way to get in the business. But, I later took classes at Austin Community College. I wanted to make sure I had the latest knowledge in the industry and wanted a little help with getting my own business started. Besides, I think customers pay you a little more respect when you can say you went to a certain school to learn the trade.
Q: What do you like best about your job?
A: I got into this business because I like working with my hands. I like figuring out what is wrong with something and seeing if I can fix it. Some jobs can be a little frustrating and hard to finish – especially when I am working in a tight area or when it is 100 degrees out and I am working on someone’s broken air conditioner. Still, I like the challenge.
I also like that I get to help people out. It is really satisfying to see the look of relief on a person’s face when I show up and get their unit fixed on the same day it broke down.
Q: Describe your typical day on the job.
A: I usually have some kind of schedule for the day, but I also take on emergency calls. This means that some days can be really long because I might have a large number of people who need me to get there as soon as possible. This sometimes means moving my schedule around so I can take care of the emergency situations. Every job is like a new adventure since I can’t know what is wrong until I get to the customer’s house. After I figure out what is wrong with the unit, I then have to order the part if I don’t have one in stock.
Q: What traits do you feel are necessary to be successful as a HVAC specialist?
A: I’d say being flexible is the most important trait. You might start off the day with what looks like an easy schedule. Before you know it, you are throwing your schedule out the window and you are working until 9:00 at night. You have to be able to go with the flow and not get frustrated when your schedule changes. I guess you have to be pretty organized too. Otherwise, you won’t be able to fit all of your customers in and you’ll waste a lot of time that could be used fixing someone’s unit.
Q: Would you recommend this career to someone else?
A: Yes. It is a good paying job. And, even with the problems we are having with our economy, I am still working steady. No matter how bad things get, people still need their heating and air guy.
Q: What is your next career move, if any?
A: Getting my own business going was always my dream and I have achieved that. I guess I could try to become a franchise or something, but I am pretty happy with where things are now. Really, for me, the next major goal is retirement!
