A Day in the Life of a Tragar HVAC Technician

Behind every comfortable Long Island home is a technician working to keep it that way — whether that’s routine maintenance or a fast response when the heat suddenly goes out. We sat down with Carlos, one of Tragar’s Service Field Supervisors, to get an honest look at what the job actually involves, from his first call of the day to the training that got him here. 

Carlos has been with Tragar for seven years and has worked in heating and air conditioning for over 18 years. Whether you’re a homeowner wondering who’s arriving at your door or you’re comparing the HVAC technician jobs Long Island employers offer, Carlos’s experience provides an honest look at the work.

Morning — Gearing Up

At Tragar, techs take their trucks home at night, so the day starts right from the driveway. “You get a call, start the shift at 8:00 in the morning, and head to the first call,” Carlos explains. Once that job’s done, dispatch sends the next one.

Thursdays look a little different. The team gathers at the office around 7:45 a.m. for a service meeting, and the morning sometimes includes a stop at the shop for parts or a scheduled parts day. From there, it’s back out to the next customer’s house to finish the day’s work — then home, ready to do it all again tomorrow.

On the Job — What Our Techs Actually Do

An HVAC technician’s day can include diagnostics, repairs, maintenance, installations, and plenty of conversations with homeowners. Carlos’s own background spans plumbing, heating, A/C, installation, and service, so he understands how one system can affect the comfort of the whole home. The technical knowledge matters, but so does explaining what is happening and helping the customer understand the next step.

One call Carlos remembers involved a damaged furnace control board on a hot evening. The suppliers were already closed, but the household needed its A/C. Carlos found a safe temporary way to get the system running, then returned to replace the board when the part became available.

That kind of problem-solving is what he says he likes most about the work. “You get a sense of gratification when you get things working,” he says. “You’re also working in different houses and going to different places; you’re not stuck in one spot all the time.”

The Training Behind the Truck

Carlos attributes most of his growth and knowledge to hands-on, on-the-job technician training across installation and service work — though he’s built a solid certification base too, including National Oilheat Research Alliance (NORA) credentials and an EPA Section 608 certification (required to handle refrigerants).

His path started in construction, then BOCES — a New York vocational training program — where he learned the plumbing and heating fundamentals before going to work for a plumber to build on those skills. He went back to school in 2013 to focus on air conditioning, and has been in heating and cooling ever since. “It was easy for me to transition into a lead tech and field supervisor position because I was well-rounded in all phases of the trade when it comes to heating and air conditioning,” he says. 

For anyone searching for HVAC apprenticeship NY opportunities or exploring HVAC careers Long Island has to offer, Carlos’s path shows how hands-on training can lead to long-term growth.

Why Our Techs Stay

Carlos has been with Tragar for seven years now. What has kept him here is not only the work, but the way the company treats its people: “It’s a great company to work for,” Carlos says. “It doesn’t feel like a big corporate company.” He values the flexibility Tragar has shown when family scheduling requires a late start or an early departure, as well as competitive compensation and benefits. 

He describes the culture as genuinely friendly, supportive, and focused on doing the job well rather than competing with one another. Carlos isn’t a veteran himself, but he has family members who served, and he also says he’s thankful for Tragar’s veteran-owned roots and what they represent.

Tragar has been Long Island’s Family of Comfort since 1956. The company is family- and veteran-owned and was recognized as a 2025 Long Island Top Workplace. Learn more about us and what that culture actually looks like day to day. As Carlos puts it: “There is growth at this company. I’m a witness to that.”
