What the technician shortage costs a home services shop

The constraint is staffed trucks, not demand

In most businesses a vacancy is lost productivity. In a service shop it is a revenue ceiling you can see from the parking lot. The calls are there, and the seasonality guarantees they will spike. Every truck without a technician is a day of booked work going to backlog, reschedules, or a competitor. None of that shows up as a recruiting expense, and all of it is real money a job ad never captures.

The shortage behind it is structural, not cyclical. Industry reporting puts the HVAC trade about 110,000 technicians short, with roughly 25,000 exiting the workforce each year. The gap is projected at 225,000 unfilled positions by 2027, or about 1.8 open jobs for every available technician. The federal data agrees on direction. The Bureau of Labor Statistics counts about 425,200 HVAC mechanic and installer jobs and projects 8 percent growth through 2034. It expects about 40,100 openings a year, most of them replacing people who leave the trade. Retirements are outpacing new entrants, and no hiring budget changes that arithmetic.

What it means at the shop level is simple and uncomfortable. Every technician you lose is hired back out of a pool that is already 1.8 jobs deep per candidate. Hiring alone runs 6 to 10 weeks in published estimates before the ramp even starts. In a market like that, the shops that win are not the ones that recruit hardest. They are the ones that stop losing the technicians they already trained.

An empty truck risks $2,000 to $7,800 a day. A departure runs $15,000 to $25,000

The most quotable number in the vertical is the daily one. An average technician generates $200 to $650 in revenue per service call and runs 10 to 12 calls a day in peak season. A single unfilled position can therefore put $2,000 to $7,800 of revenue at risk per day. Two things about that figure deserve saying plainly. It is gross revenue, the size of the schedule the truck was carrying, not the margin you keep. And it is a peak-day figure. An average day runs lower, and other trucks absorb part of the load, at the cost of backlog, longer days, and slipping response times.

The per-departure figure stacks four costs. Published all-in estimates put replacing a journey-level technician at $15,000 to $25,000. That figure counts recruiting and hiring, plus the paid ramp before the new hire bills at rate. It also counts the office time on the exit and refill, and the schedule the empty truck could not bill. The timeline is what makes it expensive. It runs 6 to 10 weeks to hire, then 4 to 8 more weeks to full productivity. The unbilled schedule usually outweighs everything else combined. Treat the range as a planning estimate from industry sources, not a benchmark of record, and build your own figure from what you spend.

The empty truck Where the money goes

The biggest line and the least budgeted. Weeks empty, times the billed hours that schedule was going to run, times the margin between your billed rate and the wage. It never appears in the hiring budget because it is not a bill anyone sends you. It is revenue that quietly never arrives.

The techs who absorb it Highest hidden cost

Lower visible cost, far higher real cost. The load from the empty truck lands on your remaining technicians as longer days and heavier on-call. In a market with 1.8 open jobs per tech, the recruiter texts they get are not hypothetical. Losing a second technician to the load from losing the first is how one vacancy becomes two.

The customer and the board Where it compounds

The costliest losses walk a customer out the door. A rescheduled call feels small once. By the second or third slip the customer has called whoever answered, and peak season means your competitors are answering. Each vacancy also pulls dispatch and office hours away from the work that grows the shop.

Put a real number on the empty truck and the departure

Borrowed ranges start the conversation. Your own numbers end it. The build is simple. For the truck, start with your completed calls per day and your average ticket. Add the days the position sits open, and an honest share of those calls you lose outright rather than absorb. For the departure, start with your recruiting and hiring costs and the paid ramp hours at wage. Add the office time on the exit and refill, and the billed schedule the vacancy could not run at your margin.

The two free calculators below do this in your browser. One prices the revenue one empty truck puts at risk per day and over the whole vacancy. The other prices a single technician departure and a year of them at your own counts. The point is not precision to the dollar. It is to make the preventable share large enough that someone decides to work on it.

A word on what you pay, and why the math needs to be visible

Pay is the lever most owners pull first, and in this trade it is hard to see clearly. Pay plans mix hourly rates with commissions, spiffs, on-call loads, and seasonal swings. The market context is real. The national median for HVAC mechanics and installers is $59,810 a year, about $28.75 an hour. Competitive markets are quoted at $65,000 to $85,000 base for journey-level technicians, with $2,000 to $5,000 signing bonuses. A technician who cannot predict their own check from your plan will read a competitor’s simpler offer as a raise even when it is not.

The practical takeaway is not a pay rule, it is visibility. Put each technician’s plan on one page they can predict. Price covering and after-hours hours at what your own payroll pays for them. Run every raise against the departures it would prevent. Confirm with your payroll provider or counsel how your plan must treat each pay element. That varies by plan design and by state. This note is general information, not legal advice.

The shortage is a standing condition, not an event

A shortage this structural does not resolve between seasons. The shops that handle it best stop treating staffing as an emergency and start running it as a standing number. The workforce figures worth watching are the ones that move before revenue does. They are empty-truck days per quarter, first-year survival of new hires, time to fill the last opening, and the on-call load per technician. Those track the things you control. They show whether a new technician gets a real first year and whether the after-hours load is visible and fair. They show whether anyone talks to a technician before they are already returning recruiter calls.

In a market where every shop is hiring from every other shop, retention is the only recruiting channel you fully control. The cheapest technician to put in a truck is the one already in it.
