Hourly, Flat Rate, or Service Call?
Most HVAC contractors run all three. Knowing how to price HVAC jobs comes down to whether you can see the full scope before you open the unit.
Charge a $75 to $200 service call fee for the trip and diagnosis, then price the repair. Many contractors credit it toward the work if the customer proceeds. In peak summer and winter, a higher diagnostic is standard.
Hourly range: $70 to $130/hr self-employed, $110 to $185/hr for a licensed shop with trucks and techs.
Capacitor, contactor, motor, and other common repairs belong in a flat-rate book so pricing is consistent across techs and you are paid for speed. The customer gets one number with no surprises.
Hard-to-find refrigerant leaks, electrical gremlins, and old systems belong on time and materials. Quote a not-to-exceed range and document what you find before committing to a firm price.
