HVAC Service Call Fees: What to Charge and Whether to Waive It
The service call fee is the first price a new customer hears from you. Owners argue about it constantly: charge it, credit it, waive it, or advertise "free service call." There is no single right answer, but there is a right way to decide.
What the fee pays for
Before a tech touches the equipment you have already paid for:
- Drive time to the house
- The truck: fuel, insurance, payment, and the stock on it
- Dispatch and phone time
- The tech's time to find the fault
None of that is free if the customer declines the repair.
Setting the number
Start from your labor rate.
Fee = (average drive time + average diagnostic time) × labor rate.
Example numbers, to show the arithmetic only: 30 minutes of driving and 45 minutes of diagnosis at $140 per hour comes to 1.25 hours × $140 = $175. A shop might charge that, or charge less and recover the rest in its repair prices. Either way, know the real cost so the choice is deliberate.
After-hours and weekend calls cost you more in overtime, so most shops use a higher fee for them.
Three ways to handle it
| Approach | Good for | Watch out for |
|---|---|---|
| Charge it, no credit | Covers every truck roll | Higher price to say on the phone |
| Charge it, credit toward the repair | Customer feels the fee wasn't wasted, and is more likely to approve the work | Repair prices have to carry the diagnostic time |
| Waive it or advertise it as free | More calls, useful when the schedule is empty | Price shoppers and second opinions. Repair prices have to cover all the unpaid visits. |
Maintenance agreement customers often get a reduced or waived fee as a membership benefit. See maintenance agreements.
Say it on the phone
Give the amount before booking, in one sentence, and say what it includes. For example: "Our diagnostic fee is $X. That covers the trip and finding the problem, and the tech will give you a price for the repair before doing any work."
A customer who hears the fee for the first time at the door feels tricked. A customer who agreed to it on the phone is already a better lead.
Flat-rate shops
With flat-rate pricing, the diagnostic fee is one line in the price book and each repair is another. Decide whether repair tasks assume the diagnosis has already been paid for, and keep that the same across the whole book. See flat rate vs. time and materials.
Common mistakes
- Copying a competitor's fee without knowing your own cost per truck roll.
- Hiding the fee until the tech arrives.
- Waiving it for everyone and never checking how many free calls turn into paid work.
- Charging the same fee at 2 p.m. on a Tuesday and 2 a.m. on a Sunday.
- Letting techs decide on the spot whether to charge it. Set a rule and keep to it.
FAQ
Is a service call fee the same as a diagnostic fee?
Shops use the words differently. Some charge a trip fee for showing up and a separate diagnostic fee for the testing. Most residential shops combine them into one. Whatever you call it, tell the customer what it covers.
Should I offer free estimates?
For replacement quotes, most shops do, because the sale is large. For repairs, finding the fault is the skilled work, and most shops charge for it.
Will charging a fee lose me calls?
Some. The callers you lose are mostly the ones looking for a free opinion. Track booked calls and average ticket before and after any change, and judge by the totals.
