How to Hire an HVAC Technician: A Guide for Shop Owners

By BRIX Editorial Team · Updated

Hire an HVAC technician when you're booked out several days in peak season and turning away maintenance work in the shoulder months. Check EPA Section 608 certification and any state license, test skills on a paid ride-along, and pay near your state's median; BLS puts HVAC techs at specialty trade contractors at $28.88 an hour.

Key takeaways

  • The hiring signal is booked-out days and declined work, measured before peak season, not during it.
  • EPA requires technicians who handle refrigerant to hold Section 608 certification; many states and cities also license HVAC work.
  • BLS projects 11% employment growth for HVAC mechanics from 2025 to 2035, so recruiting is year-round.
  • A paid ride-along or working interview tells you more than any question about superheat.
  • Pay benchmark: $28.88 at specialty trade contractors, $29.33 nationally (BLS, May 2025).

When should you hire another HVAC tech?

Hire when demand is steady enough to keep a new tech busy outside the hottest and coldest weeks. HVAC is seasonal, and a tech hired in the middle of a July heat wave starts when you have no time to train them and may sit idle in October. Look at last year's numbers and plan the hire for spring or early fall.

  • Booked out three or more days for several weeks of each peak season.
  • Maintenance agreements falling behind: tune-ups not done before the season starts.
  • Replacement leads waiting because service techs are tied up on repairs.
  • Overtime every week for your current techs, with burnout showing.
  • Utilization already high: check with the technician utilization calculator.

If the board isn't full, the problem may be booking, not staffing. Price your missed calls with the missed call calculator before you add a truck.

What certifications and licenses should an HVAC tech have?

Check refrigerant certification first. The EPA requires technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants to be certified under Section 608. The test has a core section and three types: Type 1 for small appliances, Type 2 for high-pressure systems and Type 3 for low-pressure systems; residential service techs need at least Type 2. EPA doesn't issue cards itself, so ask to see the certificate from the testing organization.

Credentials to check before an offer
CredentialWho requires itHow to verify
EPA Section 608 (Type 2 or Universal)Federal rule for refrigerant handlingCertificate or wallet card from the approved certifying organization
State or local HVAC licenseMany states and some cities; rules varyYour state licensing board's online lookup
Driver's license and clean driving recordYour insurer, for company vehiclesMotor vehicle record check, with the candidate's consent
Manufacturer or NATE-style certificationsOptional; some employers prefer themCertificate; treat as a plus, not a requirement
BLS notes that some states and localities license HVAC technicians. Check the licensing hub and your state board. Candidates can prepare for the 608 exam with the EPA 608 practice test.

Where do you find HVAC technicians?

The best HVAC techs already have jobs, so build a pipeline rather than posting only when someone quits. BLS reports that most HVAC techs complete a postsecondary program, so trade schools are the most reliable source of new talent, while experienced techs come mostly through referrals.

  • HVAC programs at community colleges and trade schools. Offer to teach a class or host students for ride-alongs; you'll meet the best ones first.
  • Referrals from your own techs, with a bonus paid after the new hire stays 90 days.
  • Supply house counters. Counter staff know which techs are unhappy where they are.
  • Installers ready to move up. An install helper who wants to run service calls is often your best hire.
  • Veterans and military HVAC or mechanical specialists.
  • Job boards and social groups, with the pay range, schedule, truck policy and on-call rotation up front.

How do you test an HVAC tech before hiring?

Pay the candidate for a half-day ride-along with your best service tech. You'll see how they diagnose, how they talk to homeowners and whether they leave the job site clean. Tell your senior tech what to watch for, and ask them to score it the same day.

  1. 1

    Check the basics first.

    608 certificate, license if required, driving record. Don't spend half a day with someone you can't put in a truck.

  2. 2

    Set up a real call.

    A no-cool or no-heat service call, or a staged problem on your shop's training unit (a bad capacitor, a dirty flame sensor, a low charge).

  3. 3

    Let them lead.

    Your senior tech watches and only steps in for safety. Note their diagnostic order and the tools they reach for.

  4. 4

    Watch the customer moment.

    Do they explain the problem in plain words, give options and ask before doing extra work?

  5. 5

    Score it the same day.

    Diagnosis, safety, customer communication, cleanliness, paperwork. A simple 1–5 for each.

What should you pay an HVAC technician?

BLS reports a May 2025 median of $28.88 an hour for HVAC techs at specialty trade contractors and $29.33 across all industries. The bottom 10% earn under $19.25 and the top 10% over $45.78. State medians run from $23.13 in Arkansas to $37.23 in Alaska. The HVAC technician pay guide has state tables, pay plans with overtime math and the cost per billable hour.

How do you onboard a new HVAC tech?

A 30-60-90 day plan for a new HVAC service tech
By dayShould be able toMeasure
30Run maintenance visits alone; know your price book, forms and truck stockTune-ups completed, paperwork accuracy
60Run standard repair calls alone; present options to homeownersCallbacks, average ticket, customer reviews
90Handle most service calls including no-heat emergencies; take on-call shiftsCallback rate, membership sales, billable hours

BLS notes HVAC techs may work evenings, weekends and overtime in peak seasons and may be on call. Explain your on-call rotation, truck policy and how overtime works with your pay plan before day one, in writing. The full hiring and pay cycle across trades is in how to hire and pay technicians.

Frequently asked questions

What qualifications should an HVAC technician have?

At minimum, EPA Section 608 certification (Type 2 or Universal for residential service), a valid driver's license and, where your state or city requires it, an HVAC license. BLS says most techs complete a postsecondary program, often a certificate. Hands-on diagnostic skill matters more than paper, so test it.

Is it hard to hire HVAC technicians?

Often, yes. BLS projects HVAC mechanic and installer employment to grow 11% from 2025 to 2035, much faster than average, with about 40,600 openings a year. Shops that recruit year-round, partner with trade schools and train helpers into techs have an easier time.

Should I hire an experienced tech or train a helper?

Most growing shops do both. An experienced tech is productive fast but costs more and may bring habits you'll need to change. A helper or trade school graduate takes a year or more to run calls alone but learns your way of working. Plan the mix around how much your senior techs can train.

What is a ride-along interview?

A paid half-day where the candidate goes on real or staged service calls with your senior tech. You see diagnosis, safety habits and how they talk to customers. Pay for the time; unpaid working interviews can raise wage-and-hour problems.

When is the best time of year to hire an HVAC tech?

Spring and early fall, before the cooling and heating peaks. A new tech then has a few weeks of tune-ups and lighter calls to learn your systems before demand spikes. Hiring in the middle of a heat wave leaves no time to train.
