What does it cost to hire (and to lose) an HVAC or plumbing tech?

Start with the honest answer: our research found no primary source for a cost-per-hire figure for HVAC or plumbing technicians, so we have no national number to copy, and this page will not invent one.

What you can do is build the number the way an accountant would: line by line, from your own records.

A hire's invoice has three parts — cash you pay out, hours your team spends, and equipment the new tech consumes.

The cash lines leave a paper trail.

Sourcing: job board fees, boosted or sponsored posts, and any referral or signing bonus you paid to land this particular tech.

Screening: the background check, motor vehicle record, drug panel or skills test your policy requires.

Onboarding admin: payroll setup, uniforms, and the compliance paperwork a new employee requires.

Line by line, these are the costs that slip past the mental accounting — until the whole stack is priced.

The hour lines carry no paper trail — they are your hours or another manager's.

Writing the ad, reading applications, phone screens, in-person interviews, a working interview, reference calls: someone in the shop does each, and that person's time has a value to the shop.

Price the hours at what that time is worth, not at zero, because that is what the seat costs while they sit in it.

Each step is a skill of its own; the complete walkthrough of hiring HVAC and plumbing techs covers the process from posting to offer.

The equipment line starts on day one, not after the tech proves out: a truck's payment and insurance, fuel, and the tools you stock it with all post whether the tech bills or not.

Add the three parts together — sourcing and screening cash, hours at their real price, and the truck rolling from day one — and you have your cost per hire: a number that includes the ad invoice rather than stopping at it.

This is the second number our research cannot hand you: it found no primary source for time-to-fill, cost-per-hire or turnover figures for HVAC or plumbing, and a crossover date quoted without your books behind it is not a number you can budget on.

The honest version runs through your own ledger: track the new tech's billed revenue each week against their loaded cost each week — pay, taxes and insurance, the truck — and the week revenue crosses cost is your breakeven.

Until then, the hire is a cost center by design, and the window has a price tag.

What the window costs is easy to list.

The tech collects full pay while their output is still building.

The truck, fuel and insurance run at full price.

If you run ride-alongs, the senior tech's day now includes a passenger, and the day's output carries two paychecks.

For scale, the United Association describes its apprenticeships as registered with the U.S. Department of Labor and typically five years long, covering plumbing, pipefitting, HVACR, welding and fire protection — the union pipe trades' registered path, not a clock on your new hire's crossover.

That crossover is what your books are for.

What the market pays while you wait is on our HVAC technician salary and plumber salary pages — BLS wage tables by role and state — so the pay line in the crossover math is grounded, not guessed.

The second lever sits on your side of the ledger: what the tech does in the early weeks fills the other side of that math.

A structured start — a planned first week and check-ins at set intervals — is its own subject, and our guide to onboarding new technicians covers the first weeks in order.

A lost tech is easiest to price as one of two things: the quit you might have kept, and the bad hire you should not have made.

Both re-open the same invoice.

The sourcing cash and the screening hours from the first section get spent again.

The ramp-up window from the second section starts over at zero.

And between the departure and the replacement's crossover sits an empty seat: the capacity is gone, but the overhead is not, and the schedule reroutes around the hole — where overtime covers the gap, that premium is its own line.

A bad hire carries lines of its own.

There are the wages paid during a ramp that never crossed over, the customers who experienced the learning curve, and the manager hours spent coaching a fit that was never there — then the full tally again for the replacement hire.

A cheap-looking hire can turn out to be the expensive one, because a bad hire's bill adds the second cost-per-hire on top of the wages already paid.

This is why turnover deserves a standing line in the budget even in a normal market.

The Bureau of Labor Statistics projects about 40,600 openings a year for HVAC mechanics and installers over 2025–2035, mostly from replacing workers who leave or retire, with employment projected to grow 11% over the decade; for plumbers, pipefitters and steamfitters it projects about 42,000 openings a year, with 7% growth.

The monthly JOLTS series adds openings and quits, with its caveats: in August 2026 (preliminary figures, seasonally adjusted), the construction industry — all trades, not just yours — carried 251,000 job openings, an openings rate of 2.9% against 4.5% for all private industry, and logged 152,000 quits in the month, a quits rate of 1.8% against 2.1%.

The cheapest hire on this page is the one you never have to make.

Our guide to retaining HVAC technicians covers the moves — pay-plan clarity, a visible ladder, fair on-call, trucks that work — plus how to measure your own turnover rate and run stay interviews before the recruiter calls.

Price a quit at this page's full stack, and the retention budget makes its own case.

Work the three parts of the invoice in order.

Sourcing: post where the trade already reads and measure each channel — spend divided by hires it actually produced — instead of spreading budget thin across every board.

The channel-by-channel comparison, board pricing models and sponsorship questions are covered in our guide to job boards for hiring HVAC and plumbing techs.

The ad itself is a lever you own outright: an ad that states the licence requirement, the pay plan's shape and the territory up front is built to filter mismatches before they cost interview hours — the ad-writing specifics are in our guide to writing job ads for techs.

Screening: spend a little structure here to avoid buying a ramp that never crosses over.

A skills test and a working interview cost hours at the front of the funnel, and both are built to surface a mismatch before the offer rather than after.

Referral programs shift sourcing to the techs already on your trucks — our guide to employee referral programs covers how to structure one.

Ramp: the onboarding structure from the second section is the lever — what the tech does in the first weeks is the other side of the crossover equation, which is why the plan belongs before day one.

And retention multiplies the savings: a tech you keep is a cost-per-hire you do not pay again.

When the calendar says you do need one more, post the opening where the trade already reads, measure what the hire actually cost, and the next one gets priced on purpose.
