An HVAC tune-up in San Jose costs $80 to $200 per visit, and about $150 is typical. A single air conditioner or furnace check sits at the low end. A visit that covers both systems costs more than either alone, but usually less than two separate trips. The price covers the inspection, cleaning and adjustments. Any repair the visit turns up is priced on its own and done only if you say yes.
Tune-up prices
| Visit | Typical price | When to book |
|---|---|---|
| AC tune-up | $80–$150 | Spring, before the first hot week |
| Furnace tune-up | $80–$150 | Early fall, before the cool nights |
| AC and furnace in one visit | $150–$250 | Spring or fall |
A yearly plan puts these visits on a schedule, so nobody has to remember them. See maintenance plans for what a plan includes.
What the AC visit covers
- Cleaning the outdoor coil and clearing leaves and debris from around the unit.
- Testing the capacitor, inspecting the contactor and tightening electrical connections.
- Checking refrigerant pressures and the temperature drop across the indoor coil.
- Flushing the condensate drain and testing the float switch.
- Checking the filter, the blower and the airflow.
- Confirming the thermostat starts and stops cooling as it should.
What the furnace visit covers
- Cleaning the flame sensor and inspecting the burners and the ignitor.
- Checking the inducer, the pressure switch and the limit and rollout safety switches.
- Inspecting the heat exchanger and the vent for cracks, rust or blockage.
- Checking the gas pressure and the burner flame.
- Checking the blower and its motor.
- Checking the filter, and on a high-efficiency furnace the condensate drain.
What moves the price
Type of system. A heat pump runs in both seasons and benefits from two checks a year. A ductless system has a filter and a coil in every indoor unit, so each extra head adds time.
Single or combined visit. Both systems in one visit costs less than two trips.
Plan or one-time. A plan schedules the visits for you. A one-time tune-up is fine when you remember to book it yourself each season.
Parts and filters. A replacement filter or a weak capacitor found during the visit is priced as a separate item, before it is installed.
If the technician finds a problem
Common findings are a weak capacitor, a dirty flame sensor, a pitted contactor, a slow condensate drain or a dusty blower wheel. You get the price for the fix before any work, with no hidden fees, and you can approve it, decline it or schedule it for later. The tune-up price does not change either way. A capacitor replaced in April is a planned repair; the same capacitor failing in July is a no-cooling call on the hottest day of the month. For what those repairs cost, see the AC repair cost guide.
Is a tune-up worth it?
The reasons are practical rather than magic:
- A dirty outdoor coil makes the compressor work against higher pressure and draw more power every afternoon.
- A weak part caught early is a scheduled repair rather than an emergency.
- A clean flame sensor heads off one of the most common no-heat calls.
- The furnace inspection looks for safety problems: a damaged heat exchanger, a blocked vent, a rollout switch that has tripped.
- Some manufacturer warranties ask for proof of regular professional maintenance.
When maintenance stops making sense
A tune-up keeps a healthy system healthy. It cannot revive a worn-out one. If the visit finds a compressor drawing far more current than it should, a cracked heat exchanger or a coil that leaks every year, the money is better put toward a replacement, and estimates for new systems are free. Be wary, too, of a “tune-up” that amounts to a filter change and a glance: ask what was checked and what the readings were.
Timing for San Jose
Book the AC visit in spring, before afternoons on the valley floor reach the 90s and schedules fill up. Dry summers coat outdoor coils with dust, and an air handler in the attic works in some of the hottest air in the house. Book the furnace visit in early fall, before the first cool nights, when furnaces that sat idle since spring try to light. In Blossom Valley and Evergreen, where many homes run older or builder-grade equipment, the yearly check is also a good moment to talk about how many seasons the system has left. Between visits, change the filter on time; the filter guide explains how often. More on each service: AC maintenance and furnace maintenance.
