DOL Recovers $122,000 in Back Wages From HVAC Contractor — What Every HVAC Employer Needs to Know

A Mississippi HVAC contractor just handed the Department of Labor $122,000 for a mistake that is easier to make than you might think. HVAC employer compliance is not a back-office concern — it is a front-line business risk. If you run a heating and cooling business and have technicians on payroll, this case is your wake-up call.

The DOL recovered $122,000 in unpaid back wages from AirSouth Cooling and Heating, a Mississippi-based HVAC company, after investigators found the business failed to properly include non-discretionary bonuses when calculating overtime rates. Two employees were also not issued final paychecks. These are not exotic violations. They happen in HVAC businesses across the United States every single week.

What AirSouth Got Wrong

The core violation was straightforward: AirSouth paid bonuses to its HVAC workers — performance bonuses, attendance bonuses, or production incentives — but when calculating overtime pay, the company did not fold those bonuses into the regular rate of pay. Under the Fair Labor Standards Act, that is illegal.

Here is why it matters: overtime must be calculated at 1.5 times the regular rate of pay. If a technician earns a $500 monthly productivity bonus, that bonus must be included when calculating what their "regular rate" actually is. Most payroll software does not do this automatically unless it is configured correctly.

The DOL's Wage and Hour Division recovered $122,000 in back wages for 140 HVAC workers after AirSouth Cooling and Heating failed to include non-discretionary bonuses in overtime calculations — a violation of the Fair Labor Standards Act.

What Counts as a Non-Discretionary Bonus?

This is the term that trips up HVAC employers most often. A non-discretionary bonus is any bonus that employees expect to receive based on a formula, performance target, or prior promise. Examples include:

• Attendance bonuses paid when technicians hit a monthly attendance target

• Productivity bonuses tied to job completion rates or revenue generated

• Safety bonuses promised to employees who avoid incidents

• Retention bonuses paid after a set period of employment

A discretionary bonus — one you decide to pay on a whim at the end of the year — does not need to be rolled into the overtime rate. But the moment you establish a system or expectation around a bonus, the DOL considers it non-discretionary. And it must be included in overtime calculations.

The Overtime Rule HVAC Owners Keep Misreading

Many HVAC business owners believe overtime is simply time-and-a-half of the base hourly wage. That belief is costing them six figures in DOL settlements.

The correct calculation: Add all regular wages plus all non-discretionary bonuses earned in the workweek. Divide by total hours worked to get the true regular rate. Pay overtime at 1.5 times that rate for any hours over 40.

If your payroll provider or bookkeeper is not doing this correctly, you are accumulating liability right now. The DOL can look back two years — three if the violation is willful. For a company with 20 technicians earning bonuses, two years of miscalculated overtime can easily reach six figures.

The Final Paycheck Failure

AirSouth also failed to issue final paychecks to two employees. Every US state has specific laws governing how quickly final wages must be paid after termination — ranging from immediately upon dismissal in California to within 72 hours in North Carolina. Failing to comply exposes businesses to additional penalties on top of the unpaid wages themselves.

For HVAC companies dealing with seasonal layoffs, technician turnover, or workforce reductions, the final paycheck obligation is one of the most commonly missed compliance requirements.

Your 5-Step HVAC Employer Compliance Audit

Run through this checklist for your business today:

• Step 1 — Identify every bonus your business pays. Write down whether each is discretionary or non-discretionary.

• Step 2 — Check your payroll software settings. Confirm that non-discretionary bonuses are included in the regular rate calculation before overtime is applied.

• Step 3 — Review your state's final paycheck law. Confirm you have a written procedure for issuing final wages within the legal timeframe.

• Step 4 — Audit the last 12 months. Pull three random payroll periods and manually verify the overtime calculations against your bonus records.

• Step 5 — Get a payroll specialist review. If your business has grown quickly or recently introduced bonus structures, a one-time HR or payroll audit is worth far less than a DOL investigation.

What This Means for Canadian HVAC Employers

Canadian HVAC businesses operate under provincial employment standards legislation rather than the US FLSA, but the underlying issue is identical. Overtime pay must reflect total compensation, not just base wages. Ontario's Employment Standards Act, British Columbia's Employment Standards Act, and Alberta's Employment Standards Code all include provisions that affect how bonuses interact with overtime obligations. If you operate in Canada, review your provincial obligations with the same urgency.

Frequently Asked Questions

What is HVAC employer compliance?

HVAC employer compliance refers to meeting all federal and state labour law obligations as an HVAC business, including correct overtime calculations, proper paycheck issuance, and adherence to wage and hour rules under the Fair Labor Standards Act.

Can the DOL investigate my HVAC business without a complaint?

Yes. The DOL's Wage and Hour Division conducts both complaint-driven and proactive investigations. Industries with known wage violations — including construction and skilled trades — are regularly targeted for review without a worker complaint.

How far back can the DOL go in an HVAC wage investigation?

The DOL can recover back wages from the previous two years. If a violation is found to be willful, that window extends to three years. For a business with 20 staff and consistent errors, three years of liability can easily exceed $100,000.

Do performance bonuses need to be included in overtime calculations?

Yes, if the bonus is non-discretionary — meaning employees earn it based on a formula or expectation. Non-discretionary bonuses must be included in the regular rate of pay before calculating overtime under the FLSA.

What happens if I miss a final paycheck deadline?

Penalties vary by state but commonly include the full amount of unpaid wages plus additional penalties. Some states allow employees to sue for double damages. A written offboarding procedure is the simplest way to avoid this risk entirely.
