A business that has grown past three technicians typically knows it needs to hire a fourth long before the search actually starts — the schedule is full, the owner is back on the tools, and two good leads went elsewhere because booking wait stretched past a week. Finding the right person has not kept pace with knowing you need them.

Skilled field technicians are harder to find than they were five years ago, and the process most Thai install businesses use — waiting to hear through a friend of a friend — misses most of the available pool. A more structured approach does not require a dedicated HR function. It requires being clear about what you need, knowing where to look, and running a short process that reveals real skill before someone is on your payroll.

Why Is It Harder to Find Technicians Now?

Vocational school graduates are not always job-ready. A technician who completed a ปวส. in electrical or refrigeration systems has foundational theory but often limited hands-on exposure to the specific equipment your business services — VRF systems, grid-tied solar inverters, IP CCTV. That gap is bridgeable, but it means the hire is not immediately productive without mentorship.

Experienced technicians have more options. Property management companies, hospitals, and large commercial operators hire technicians directly, offering fixed salaries, social security, and predictable hours. Small install businesses compete on different factors: variety of work, autonomy, and team culture — which are real advantages, but need to be offered consciously.

Word-of-mouth pools are narrower than they appear. Three technicians asked whether they know anyone available will collectively reach perhaps fifteen people. That is a thin pool for a specialised role.

Where Do Thai Install Businesses Find Technicians?

Employee referrals remain the highest-quality source. A technician who refers someone from a previous job or a trade school cohort provides a quality signal no job board can replicate. Tell your team you are looking, describe the role clearly, and offer a small recognition if the hire works out beyond probation.

Facebook groups and trade communities focused on ช่างแอร์, ช่างโซลาร์, and ติดตั้ง CCTV are active and reach people already working in the field.

Vocational school job boards. Technical colleges (วิทยาลัยอาชีวศึกษา) run placement programs. A recent ปวส. graduate with no bad habits is often more teachable than a mid-career hire with established ones.

Job portals — WorkVenture, Jobtopgun, and JobsDB reach applicants actively searching, and response rates are higher for roles with a clearly stated pay range.

What Should You Put in a Job Description?

Vague job descriptions attract vague applicants. A posting that says “technician wanted, good salary” tells a qualified candidate nothing worth responding to.

A clear description for a field technician role includes:

Specific trade: aircon (residential and light-commercial), solar PV (grid-tied systems up to 10 kWp), CCTV (IP and HD-over-coax). Not “general technician.”
Transport requirement: own motorcycle or pickup for on-site transport, or company vehicle provided. This eliminates a major source of day-one surprise.
Service area: which provinces or districts. A technician with family in Pathum Thani will not relocate for a job in Chiang Mai without it being explicitly discussed.
Working hours: be honest about weekend callouts, seasonal peaks during hot months, and what emergency on-call rotation looks like. Applicants who want predictable hours filter themselves out, which is better than discovering the mismatch after hire.
Pay range: stating a range — rather than “negotiable” — demonstrates that the business knows what the role is worth and respects the applicant’s time. It also determines who applies.

What Should You Look for in a Technician Interview?

The most common hiring mistake is evaluating personality rather than job-specific capability. A confident applicant who cannot diagnose a common fault costs you customer complaints and repeat site visits.

Ask about specific scenarios. “Walk me through a fault call on a split unit that was not cooling.” Listen for a diagnostic process — checking refrigerant pressure, testing capacitors, reading error codes — rather than a solution that arrived without explanation.

Ask about tools they own. A technician who maintains their own manifold gauge set and leak detector is invested in the trade. Reliance on the employer for every tool from day one is a different signal.

Ask what they do when they don’t know the answer. The right answer: call a senior colleague, check the service manual, or be honest with the customer and schedule a follow-up with the right equipment. Guessing and billing is the wrong answer.

Call one reference. Ask whether they would re-hire. Hesitation or a vague answer tells you something the interview did not.

How to Structure a Trial Period That Reveals Real Skill

A 30-day probation period with structured checkpoints is more useful than an indefinite trial.

Week one: paired with a senior technician on all visits. The new hire observes, assists, and handles the post-job record capture (photos, service notes) under the senior’s eye. You are assessing how quickly they adapt to your process, not testing their trade skill yet.

Week two onward: solo visits with the senior available by phone. Review each job record at end of day for completeness. A technician who consistently delivers incomplete records in week two will not improve without specific feedback — give it early.

30-day review: assess against three questions. Did customers report any concerns? Are job records complete and usable? Is the technician honest when they encounter something beyond their current skill? If all three are yes, the hire is working. If one is no, address it with a direct conversation before the probation ends.

Under Thai labour law, probation periods are commonly 30 to 119 days. Terms should be stated in a written employment agreement before the start date, including pay during probation and the criteria for confirmation.

What Does Competitive Pay Look Like?

For Thai field technicians in 2026, typical market compensation depends on trade and experience:

Entry-level (0–2 years, residential aircon or basic CCTV): ฿15,000–20,000 per month basic, plus fuel or vehicle allowance
Mid-level (2–5 years, capable across standard job types): ฿20,000–28,000 per month
Specialist (5+ years, VRF, solar PV, fire systems, or fiber CCTV): ฿28,000–40,000 per month, with some businesses adding per-job or per-project bonuses on top

The allowance structure matters as much as base pay. Technicians using their own motorcycle expect a clearly stated fuel allowance. Weekend and holiday work must be compensated — Thailand’s Labour Protection Act requires at minimum 150% of the regular rate for overtime and 200–300% for official holidays.

Per-job incentives align the technician’s interest with scheduling efficiency — more clean jobs in a day earns more. Structure it as a supplement to base pay, not a replacement.

Why Good Operations Help You Hire Better People

Technicians talk to each other. Businesses known for disorganised dispatch, lost paperwork, and constant LINE-group confusion develop reputations in trade communities. Businesses that run clean digital systems, give technicians clear job sheets before each day, and do not make technicians chase the office to find out where to go next develop a different reputation.

A well-organised business with a dispatch board, mobile job records, and consistent scheduling is a more attractive place to work for a technician with options. When you hire, you are not just evaluating the applicant — they are evaluating you.

FAQ

What if I need someone urgently and the best applicant I find is not quite right?

A wrong hire costs more than a short wait. Repeat call-backs, customer complaints, and the overhead of fixing problems add up on top of salary and onboarding. If the shortfall is urgent, use a trusted subcontractor to bridge it while you continue the search.

The new hire passed the interview but is underperforming in the first month. What now?

Have a specific, early conversation based on particular jobs or records where the standard was not met — not general feedback. Most first-month underperformance traces to unclear expectations, not inability. If there is no visible improvement in two weeks, the probation period exists to allow a clean separation before it becomes more complicated.

Should I require technicians to have their own vehicle, or should I provide one?

Both models work. Own-motorcycle with a daily fuel allowance (typically ฿100–200 for local routes) is common for smaller teams. Company pickups make more sense for installation projects that require carrying equipment. State whichever model you use in the job posting and employment agreement — vehicle responsibility is one of the most common early-hire friction points.

Managing the growing team behind your service operation — from technician schedules to job assignments and capacity — is easier when everyone works from the same system. OnSiteQ’s workforce management tools give you visibility into who is available, what each technician has on their day, and where coverage gaps are, so hiring decisions connect directly to what your capacity data actually shows.
