What the First Paycheck Actually Costs an HVAC Business Owner

The wage on the whiteboard isn't the number that matters

A lot of HVAC owners hire their first technician the same way: they figure out what a fair hourly wage looks like in their market, maybe $24 or $28 an hour, write it on a job offer, and start pricing jobs around that number. It feels concrete. It's also wrong, not because the wage is unfair, but because it's only one piece of what that employee actually costs the business.

Up to this point, most of the labor in the company has been either free or invisible. A spouse answering phones. A cousin riding along on installs. The owner's own unpaid hours stacked on top of a full workday. None of that shows up on a pay stub, so none of it forced the owner to think in terms of true labor cost. The first real employee changes that, and the gap between "what I pay someone" and "what that person costs me" is where a lot of first-year margin quietly disappears.

The three additions nobody budgets for

On top of the hourly wage, an employer is generally on the hook for three categories of cost the employee never sees on their paycheck.

Payroll taxes. Employers match the Social Security and Medicare taxes withheld from an employee's wages, a combined 7.65% under current federal rules, plus federal unemployment tax on a portion of wages paid. The IRS lays out these employer obligations in detail in its Employer's Tax Guide, which is the document to actually read before running a first payroll rather than guessing.

State unemployment insurance. Most states charge employers a percentage of wages, on a per-employee basis, into a state unemployment fund. New employers typically get a standard starting rate that can move up or down over time depending on how often they lay people off. This is separate from the federal unemployment tax and varies by state, so the number an owner in Ohio pays will not match one in Texas.

Workers' compensation insurance. This is usually the biggest surprise, and the one most specific to a trade like HVAC. Workers' comp premiums are not a flat percentage across all employees. They're priced by job classification code, because a technician climbing on roofs and handling refrigerant lines represents a very different injury risk than an office employee doing billing. A state-published rate schedule, like the one Nevada's insurance division puts out for assigned-risk workers' comp, shows exactly how rates are broken out by classification and can run from a few dollars to well over ten dollars per hundred dollars of payroll depending on the job. You can see how directly job classification drives the number in Nevada's published workers' comp rate schedule, which lists classification codes for trades work at rates well above lower-risk office roles.

Stack those three categories on top of a wage and it's common for total labor cost to land somewhere between 12% and 25% above the hourly rate, sometimes more depending on the state and the workers' comp classification. A $25-an-hour technician can easily cost $29 to $32 an hour once everything is loaded in, before a truck, tools, insurance on the vehicle, or a single benefit is added.

Why the classification on paper matters as much as the rate

Workers' comp rates are tied to job classification codes, which means how a technician is classified on the policy has to match what they actually do. An owner who classifies a field technician under a lower-risk clerical or estimating code to save money on premium is creating a real liability, not a discount. If that technician gets hurt on a roof or handling a compressor and the classification doesn't match the actual work performed, the claim can be denied, reclassified retroactively with back premiums owed, or both.

A related and more common version of this mistake is treating a technician as a 1099 contractor instead of a W-2 employee to avoid payroll taxes and workers' comp altogether. State labor regulators take this seriously. Indiana's Department of Labor, like most states, defines the tests used to determine whether a worker is genuinely independent or actually an employee, and lays out the consequences of getting it wrong, including back taxes, unpaid unemployment insurance contributions, and lost workers' comp coverage that leaves the owner personally exposed if that worker is injured on the job. Their plain-language guide to worker misclassification is worth reading before an owner decides a new tech is a contractor rather than an employee, because the label doesn't come from what's written on an invoice, it comes from how much control the business has over the work. This is the same underlying issue covered in the first subcontractor mistake most contractors make, and it applies just as directly to a technician on the payroll as it does to a sub on a job site.

Building the real number before making an offer

The practical fix is simple in structure, even if the inputs take some digging. Before offering a wage, an owner needs a loaded hourly rate: the wage itself, plus the employer share of payroll taxes, plus the state unemployment insurance rate applied to that wage, plus the workers' comp rate for the correct classification applied to that wage. Add those four numbers together and divide by the hours the technician will actually bill, not the hours they're paid for, since time spent driving between jobs, doing paperwork, or sitting through slow weeks isn't generating revenue even though it's still being paid.

That loaded rate, not the wage on the offer letter, is what belongs in a job estimate. An owner who prices work off the wage alone is quietly eating the difference on every invoice, which is the same trap covered in when a handshake estimate stops being good enough: the estimate looks reasonable until the real costs behind it get added up.

None of this is a reason to avoid hiring. It's a reason to know the actual number before writing the offer, so the first invoice under the new arrangement reflects what the work really costs rather than what it used to cost when the labor was free.
