Key takeaways
- Start with trade schools, apprenticeship programs and referrals from your own crew, then add job boards.
- Use a short phone interview to hear how a tech troubleshoots and owns mistakes, then run separate technical and fit interviews.
- Put a clear offer in writing within 24 hours, and talk about the growth path as well as the pay.
- Treat the first 90 days as part of the hire: paid shadowing, supervised calls and weekly check-ins.
What to decide before you post the job
- Whether you need EPA Section 608 certification on day one. Decide whether you require it up front or will help a candidate earn it. EPA Section 608 rules require certification for technicians who work with refrigerant, with an exemption for apprentices under close supervision by a certified tech.
- A hiring budget. Plan for job board posts, Indeed spend if you hire all year, referral bonuses, and onboarding for each new tech.
- Your contacts. Line up trade-school placement offices and apprenticeship coordinators, plus your Indeed and social accounts, so you can post the day a seat opens.
Good techs get recruited by other shops all the time, and an empty seat costs you missed install windows, callback hours and customers who go elsewhere. Strong techs also sell on the truck. They spot upgrades on a call, explain repairs in a way that builds trust, and turn one-off service into maintenance agreements.
According to CWI’s apprenticeship data, the HVAC field is projected to see strong growth in job openings through 2035, well above average for skilled trades.
This post is about finding and keeping techs. For writing the ad and checking credentials, see the guide on how to hire an HVAC technician.
Step 1: Recruit from trade schools and apprenticeship programs
Trade schools and apprenticeship programs turn out new techs on a schedule, and their instructors can vouch for them. Build the relationship early and you get a first look at each class before those techs hit the open market.
- Call the placement office directly and ask whether they’ll send graduates to your openings.
- Apprenticeship programs like NYC’s HVAC Pre-Apprenticeship graduate a class every year. Contact the coordinators before graduation.
- Post to trade-school job boards. A small post can bring in a few vetted leads each term.
- Sponsor a scholarship or an internship for top students. It costs money up front and builds loyalty early.
- Go to open houses and apprenticeship fairs, and talk shop with students face to face.
What to look for: EPA Section 608 certification, hands-on lab hours, and instructor references that speak to work ethic as well as grades.
Step 2: Ask your crew for referrals
Your best techs know other techs, and they only refer people they’d want to work next to. That makes referrals one of the strongest channels you have. Asking also shows your crew you value their judgment.
- Pay a referral bonus when someone your crew brings in stays 90 days or more.
- Make a simple “refer a tech” form so it’s easy to send a name.
- Ask in one-on-ones: “Who do you know that’s looking?”
- Before the interview, send the referred tech on a ride-along with the person who referred them.
Step 3: Post on Indeed and social media
Post where techs already look: Indeed, your metro’s HVAC groups on Facebook, and LinkedIn. A real pay range and a real tech’s face give someone who already has a job a reason to reply.
On Indeed:
- Write the ad in plain words. “We’re an HVAC shop looking for installers who care about callbacks” reads better than “Seeking HVAC professionals for high-growth organization.”
- List pay as a real range. “Competitive” tells a tech nothing.
- Say what sets you apart: fleet vehicles, ongoing training, a fair on-call rotation.
- Feature a top tech’s name and photo if they agree.
- Set a monthly budget if you hire all year.
On Facebook and LinkedIn:
- Lead with a few words from one of your techs about working for you.
- Post in trade groups and on HVAC pages.
- Run a small paid campaign aimed at HVAC groups in your metro.
Posts that get attention: a before-and-after of a tricky install, a day in the life of one of your techs, or a review from a customer.
Step 4: Check reliability and core skills on a short phone call
A résumé tells you little. A 15-minute phone call tells you much more. Ask every candidate the same questions:
- “Walk me through the most complex system you’ve diagnosed.” Listen for troubleshooting logic.
- “Tell me about a time a customer was unhappy with your work.” Reliability shows in how they own mistakes.
- “What’s your current job situation, and why are you looking?” If they’ve changed jobs every 6–12 months, ask why.
- “What do you want from your next role?” Listen for whether they want to grow.
- “How would you handle a no-heat call at 2 PM in January?” This is the pressure moment.
On the résumé, look for EPA Section 608 certification, steady tenure and ongoing training or added certifications. Ask about gaps and short jobs in the interview. In HVAC, a short gap in the spring or fall shoulder season may just mean slow work.
Step 5: Run separate technical and fit interviews
Have your lead tech run the technical interview, and you or your ops lead run the fit interview. Splitting them keeps each one focused: your lead tech can probe real skill, and you can judge fit without pretending to judge troubleshooting.
Technical interview (30–45 minutes): Bring schematics. Have them troubleshoot a live scenario. Ask about their tools. Check their certifications.
Fit interview (30 minutes): “Tell me about your best customer interaction.” “What frustrates you most about HVAC work?” “What does success look like in your first 90 days?” “How do you handle stress or conflict?”
Techs work in people’s homes, often with nervous homeowners. A candidate who passes the technical interview and struggles in the fit interview is still a risk to your reputation.
Step 6: Make a competitive offer
By now you have a short list. The offer has to be clear, and you have to sell the job as well as describe it.
The basics:
- Pay: a clear figure for trained techs, based on your local market.
- Benefits: health coverage, a 401(k) match and clear PTO.
- A vehicle, or a gas stipend if they drive their own truck.
The pitch:
- Talk about your culture and your standard for callbacks.
- Be honest about the hard parts, like summer call volume.
- Show the growth path: crew lead, then trainer.
- Offer a paid onboarding period.
Put the offer in writing within 24 hours. Good techs have options, and a vague or slow offer loses them to a shop that moved faster. Naming the pay, the growth path and the hard parts up front builds trust, and it keeps away anyone who would quit over surprises.
Step 7: Build retention from day one
Many techs decide whether to stay in the first 90 days, so treat onboarding as part of the hire.
A 90-day plan:
- Weeks 1–2: Paid shadowing.
- Weeks 3–4: Supervised calls with real feedback.
- Month 2: More independence, weekly check-ins.
- Month 3: Independent calls, still with check-ins.
- Don’t put them on call alone in the first month.
Paid shadowing and supervised calls protect your reputation while the new tech ramps up. Weekly check-ins catch small frustrations before they turn into a resignation.
Signs your process is working:
- The new tech is sticking when they ask questions about systems, show up on time, get along with the crew, and take customer frustration seriously.
- Sourcing is working when referrals and trade-school grads fill most of your seats.
- The offer is working when strong candidates accept within a day or two and show up after they sign.
