How do you keep HVAC and plumbing techs from leaving?

There is no published turnover rate for HVAC or plumbing technicians.

Our research found no primary source — government or trade association — that measures tech turnover, time-to-fill or the cost of replacing a tech, and we will not invent one.

The turnover question gets answered in your shop, not in a chart.

What the Bureau of Labor Statistics does publish points the same direction.

It 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 over the same span, with 7% growth.

When most openings exist to replace people who left, the staffing work you control most is keeping the people you have.

The monthly JOLTS data adds texture, with caveats.

In August 2026 (preliminary figures, seasonally adjusted), the construction industry — all trades, not just yours — reported 251,000 job openings, an openings rate of 2.9% against 4.5% for all private industry, and 152,000 quits in the month, a quits rate of 1.8% against 2.1% privately.

Construction workers quit somewhat less often than the private-sector average, but 152,000 quits in one month is still a lot of two-week notices.

So run your own number: count the technicians who left voluntarily over the last twelve months, divide by your average technician headcount, and watch the figure year over year.

A number you can trend beats a benchmark nobody can source — and it is the only one your pay and schedule changes actually have to beat.

Exit conversations rarely come with a neat answer, but the same handful of drivers shows up again and again: a pay plan the tech can't explain to their family, no visible next step, on-call that lands on the same names, a truck or tools that cost them more time than they should, training nobody committed to, and a manager who only appears to correct something.

None of these announces itself in a meeting.

Each one quietly reopens a question that a recruiter's call later answers.

The visible reason for a resignation is almost always money, because that is what an outside offer puts in writing.

But the offer only lands because one of the drivers above was already wobbling — the tech who is paid right, promoted on a schedule they can see, and left alone on weekends has no reason to take the call at all.

Treat a counteroffer as a symptom, not a fix: whatever made the market able to outbid you is still there after the raise.

There is also an upstream version of this problem: some turnover is a hiring mistake — a tech who was wrong for your pay plan or workload from the first week.

Separating people you lost from people you should not have hired is the first pass, and the full post-mortem of why HVAC techs quit is a subject of its own.

For the rest of this page we assume the hire was right and the job is to keep them.

A pay plan has two retention surfaces: the level and the clarity.

The level is a market question — the BLS wage tables on our HVAC technician salary and plumber salary pages show what each trade is paid nationally and by state, and your local market sets the real floor.

Clarity is entirely yours: a tech who cannot predict their check treats every thin week as the company taking something, while a tech who can explain their own pay math usually defends the plan to the new hires.

Write the plan on one page — base, what moves it, when it changes — and hand every tech the same page.

One compliance trap sits inside every commission or flat-rate plan, and it lands on the same retention surface.

Flat-rate techs are still owed FLSA overtime: the regular rate is total job pay divided by hours actually worked, plus an extra half-time for each hour over 40 in a workweek (U.S. Department of Labor rules).

Commissions — including on equipment sales or service tickets — count as pay for hours worked and go into the regular rate too.

The narrow section 7(i) exemption applies only in a retail or service establishment, only when the regular rate exceeds 1.5 times the minimum wage and more than half of pay is commissions, and whether an HVAC or plumbing shop qualifies is decided case by case.

Retention bonuses carry the same rule.

Bonuses announced to make employees work faster or stay with the company — stay-until-payment, attendance, production and quality bonuses — must be included in the overtime regular rate; only a bonus the employer decides on at or near the end of the period, with no prior promise, is truly discretionary, and an announced spiff plan is not that.

Budget for the overtime math before you announce the plan, and have an employment attorney review the plan before it goes live.

A tech who cannot see the next rung assumes there isn't one — and starts browsing shops that advertise one.

A career ladder fixes that with structure the licensing system already gives you: apprentice to journeyman to senior or lead roles, with the skills, licence tiers and pay band named for each step.

The licence ladder itself is set by your state board (or the city or county, where licensing is local), and what each tier permits is defined by the board that issued it — your company ladder maps onto it, it does not replace it.

The entry rung is well defined in the pipe trades: UA apprenticeships are registered with the U.S. Department of Labor, typically last five years, and cover plumbing, pipefitting, HVACR, welding and fire protection.

A non-union shop can build the same shape — a defined training span, timed evaluations, a published pay progression — even where it recruits from trade schools instead.

What keeps people is not the rung itself; it is knowing the rung exists and that the shop funds the climb.

Make the ladder concrete.

Name what changes between levels — which calls a tech runs alone, which equipment they touch, whether they ride along on diagnostics — attach a pay band to each level, and review progress on a schedule rather than when someone threatens to leave.

A dedicated guide to HVAC technician levels is on our list; until it ships, your state's licence tiers plus your own lead and service-manager tracks define the top of the ladder.

On-call is where retention is won or lost, because it is the only part of the job that follows a tech home.

The fixes are structural, not motivational: publish the rotation well in advance so techs can plan their lives, rotate it evenly so the same names do not always land the weekend, and be explicit about what a call-out actually requires — response time, scope, and how the time is paid.

Where the volume allows, a protected weekend after a heavy on-call stretch buys more goodwill than any pizza.

Trucks and tools are the second lever.

A tech's truck is their workplace, and a shared or swapped truck reads as the company not investing in them.

Keep assigned trucks running — a van in the shop is a tech standing still — and stock it properly so the day is not lost to supply runs.

Put the tool policy in writing: what the company provides, what the tech supplies, and where the line sits, settled before the argument happens on a Friday job.

Scheduling ties both together.

Cluster calls geographically where the calendar allows — windshield time reads as unpaid frustration in a tech's mind even when the pay plan covers it — hold a consistent start and end where possible, and defend training days the way you defend revenue days.

None of this requires a counteroffer to work, and all of it shows up in the next recruiter call the tech declines.

A stay interview is a one-on-one with a tech who is not leaving, asking what keeps them and what would push them out — run before the recruiter calls, not after.

It is not a performance review, so no scoring, and it is not an exit interview, which runs a week too late.

Put it on the calendar as its own meeting, away from the shop floor, and tell the tech honestly what it is: you would rather hear about a wobbling pay plan from them than from a competitor's offer letter.

Four questions carry most of the weight.

What would make you start looking elsewhere?

Which part of your week do you most dread?

What do you want to be doing here in a few years, and what would you need from me to get there?

If a higher offer landed tomorrow, what would you want me to match — and what would no amount of money fix?

Write the answers down; the second stay interview is worth little if the first one's answers evaporate.

Then close the loop, because this is where stay interviews usually die.

Pick the one fix you can make first — the rotation, the truck, the pay-plan page — make it, and tell the tech that is what came out of the conversation.

A stay interview with no visible follow-up teaches your best people that talking changes nothing.

And if the same answer repeats across the crew — you cannot match the market, the ladder is empty — the problem is upstream, and the guide to hiring HVAC and plumbing techs is where that work starts.
