Yes — technicians who are employees are owed overtime under the Fair Labor Standards Act unless a specific exemption applies, and pay structure doesn't opt you out: hourly, flat-rate, piece-rate and commissioned techs all earn it unless an exemption covers them.
The math runs off the regular rate — all pay for the week minus what the FLSA excludes, divided by all hours worked — with an extra half of that rate for each hour over 40.
Are techs entitled to overtime?
The rules on this page come from the Fair Labor Standards Act and the Department of Labor's overtime regulations, and they apply to technicians who are employees — whatever the pay structure looks like.
The structure changes how the rate is computed; exemptions, not pay plans, are what remove the right.
A tech paid by the hour with a production bonus is owed it.
A flat-rate tech paid per finished job is owed it — the belief that per-job pay removes overtime is false unless a specific exemption applies.
Piece-rate installers are owed it, and commissions count as pay for hours worked that must be included in the overtime rate, whether or not they are your only pay.
The exceptions are specific, and status is the first one to check.
Genuine independent contractors get no FLSA minimum-wage or overtime protection at all — and status turns on the economic realities of the relationship, not on the label in the agreement or the fact that you receive a 1099.
One exemption to know for commissioned techs, the Section 7(i) commission exemption, is covered in the flat-rate and commission section below; its tests are narrow.
How each structure's paycheck is built — effective hourly, guarantees, callbacks — is the pay-structure question, and our guide to tech pay structures compares them all.
This page stays on the overtime layer that sits on top of every one.

How overtime is calculated
Two numbers decide your overtime pay: the regular rate and your hours.
The regular rate is all pay for the workweek — hourly wages, flat-rate earnings, piece earnings, commissions, promised bonuses and spiffs, minus the FLSA's listed exclusions — divided by all hours actually worked that week.
For every hour over 40 in the week, you are owed an extra half of that rate, on top of the pay that already covered your hours.
That is why the premium is computed on the higher number and not on your base hourly alone.
The Department of Labor's regulation works the example itself: an employee paid $12 an hour works 46 hours in a week and receives a $46 production bonus.
The bonus is pay for hours worked, so it goes into the rate: 46 hours at $12 yields $552 in hourly pay, the $46 bonus brings the week's total to $598, and $598 divided by 46 hours gives a $13 regular rate — so the overtime hours are owed at $19.50, not at the $18 that the $12 base rate alone would produce.
The bonus lifted both the rate and the premium.
Everything that follows — flat rate, commissions, spiffs — is this same computation with a different number in the numerator.
If you can run the $12-and-$46 example, you can check any paycheck against it.
Overtime on flat rate and commission
Flat rate.
Per-job pay does not remove the overtime right.
For job-rate workers, the regular rate is the week's total job pay divided by the hours actually worked — every hour on the clock, not only the hours the job list paid for — plus an extra half of that rate for each hour over 40.
Piece rate, pay per install or per unit on the installation side, follows the same method: all piece earnings plus other pay, divided by all hours worked.
Where the piece earnings already covered straight time for every hour, only the extra half-time is owed — the regulation's example pays $523 for a 50-hour week, which divides to a $10.46 regular rate, so the 10 overtime hours add $52.30.
Commission.
Commissions on equipment sales or service tickets are pay for hours worked and belong in the regular rate, whether they are a top-up on hourly pay or your entire compensation.
A commission paid weekly is added to the week's other earnings and divided by total hours to get that week's rate, with an extra half of the rate owed for each overtime hour.
When a commission is paid monthly or later, the employer can pay overtime on the hourly rate first — but once the amount is known it must be apportioned back over the weeks it was earned, and extra overtime paid for each week that had overtime hours.
A monthly amount that cannot be tied to specific weeks can be allocated by multiplying it by 12 and dividing by 52.
The commission exemption.
FLSA Section 7(i) exempts commissioned employees of a retail or service establishment from overtime only if two tests hold: the regular rate is more than one-and-a-half times the minimum wage, and more than half of the pay over a representative period of at least one month is commissions.
The employer must also be a retail or service establishment — one where 75% of annual dollar sales of goods or services is not for resale and that is recognized as retail in its industry.
Courts once read a Department of Labor list as excluding air-conditioning contractors from the exemption; the DOL withdrew that list in May 2020, and whether an HVAC or plumbing service company qualifies today is decided case by case.
Do not treat the exemption as settled — and do not treat flat-rate or piece-rate pay as an exemption at all, because neither is one.
The paycheck side of flat rate — how task amounts are set, what callbacks and slow weeks do to your effective hourly — is on our flat-rate pay guide.
Spiffs and your overtime rate
A spiff is a bonus tied to a specific line of work — and for overtime purposes, what matters is whether it was promised.
A bonus is discretionary, and can stay out of the regular rate, only if the employer decides both whether to pay and how much at or near the end of the period, with no prior promise.
A spiff schedule announced in advance — pay a set amount for each maintenance agreement sold this month — is the opposite: a promised, non-discretionary bonus that must be included in the rate.
Production bonuses, quality bonuses, attendance bonuses and bonuses announced to make employees work faster or stay with the company all go in the same way, and calling a payment a discretionary bonus doesn't make it one — the facts decide, not the label.
Timing follows the bonus window.
A spiff paid in the same week you earned it folds into that week's regular rate.
A bonus that covers several weeks, like a quarterly install bonus, may be left out of the overtime math until the amount is known — but once it is, it must be apportioned back across the weeks it covered, and extra half-time paid for every one of those weeks that had overtime hours.
A shop that skips the catch-up is shorting the overtime hours you already worked.
Which lines carry spiffs, what a spiff-heavy pay plan hides, and the red flags worth walking away from are the spiff-specific questions — our spiffs guide covers them.

State daily-overtime rules
Every rule on this page so far is weekly: each one pays its premium for hours over 40 in a workweek, and none of them pays extra for a long day by itself.
Counted the way those rules count, a 12-hour Monday and an 8-hour Tuesday simply feed the same weekly total.
State wage-and-hour law may add requirements on top of the FLSA.
Here is the honest limit of this page: our research did not confirm state-by-state daily-overtime rules, so we won't list states or thresholds we can't source.
Whether your state pays a premium past a daily hour count, and how a state daily rule would stack with the federal weekly one, is a question to take to your state labor department.
The federal weekly right is the baseline you can check any paycheck against; if your state has its own overtime rule, it may entitle you to more than the FLSA alone.
Ask the payroll question in state terms — "how do you compute overtime here?" — and check the answer against the federal rule and whatever your state adds.

Seasonal overtime
In HVAC work, the overtime hours track the seasons — BLS notes that technicians sometimes work overtime or irregular schedules during the peak heating and cooling seasons.
The fuller schedule picture: most HVAC technicians work full time, schedules may vary to include evening or weekend shifts, and they may be on call for emergencies.
Peak seasons are when the long weeks land — and when the regular-rate rules above start mattering on a real paycheck.
What on-call rotations pay before any call comes in is its own question — our on-call pay guide covers the models.
Overtime is also the reason published wage data understates some techs' real earnings.
The BLS OEWS survey excludes overtime pay, shift differentials, nonproduction bonuses such as sign-on or holiday bonuses, and benefits — so a tech who logs heavy overtime can earn more in a year than the published figures show.
The benchmark medians, for the record: $29.33 an hour, or $61,010 a year, for HVAC mechanics and installers (SOC 49-9021), and $30.67 an hour, or $63,800 a year, for plumbers, pipefitters, and steamfitters (SOC 47-2152), both from OEWS May 2025.
Read them as wages before overtime, as BLS measures them, not as a ceiling.
The state-by-state tables are on the HVAC technician salary and plumber salary pages.
One practical takeaway ties the seasons to the rules: the weeks with the most overtime are the weeks the regular-rate math matters most in.
Check your heaviest seasonal paychecks against the method above — that is where an error costs the most.
