Three months of real work for your air conditioner
Your air conditioner in Santa Clara County works from July through September. That is when the demand shows up, on afternoons that average 82°F. The compressor carries that load and it does it in a short stretch instead of across the whole year.
A tune-up before that stretch starts looks at what those afternoons will lean on. The refrigerant charge, the condenser coil, the electrical connections that heat up with steady running. Finding a weak part before July means it gets fixed on your schedule, not on the afternoon the unit finally gives out.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
California requires HVAC contractors to hold a state license.
The Contractors State License Board tests and licenses HVAC contractors in California. The license covers the contractor, not each job, so it is the business you hire that carries it, not the work order for this one visit.
For a maintenance visit, that license is what stands behind the person coming to your house. If the technician needs to open up the refrigerant side of your air conditioner, checking charge or adding refrigerant, federal law also requires EPA Section 608 certification. That certification is separate from the state license and applies the same way in every state.

- What does AC maintenance include?
- A technician checks refrigerant charge, cleans or replaces the filter, and clears the condensate drain so it isn't clogged. They check the condenser coil outside for dirt and debris, test the capacitor and contactor, and check that the system is cycling properly. They also check that the thermostat is calling for cooling correctly. Most of this catches problems while they're still small, before a part fails during the months the system runs hardest.
- How often does an air conditioner need maintenance?
- Once a year, ideally before the season it works hardest. Homes in San Jose need cooling from July through September, so having the system checked before then means it's ready when the heat arrives. A yearly check catches a weak capacitor or a dirty coil before those months of daily use find it for you.
- Is AC maintenance worth it?
- Yes. A dirty coil or low refrigerant charge makes the system run longer to cool the same house, and running longer means more wear on the compressor and fan motor. San Jose only asks the system to work hard for about three months a year, but hail and wind events here can leave debris in the outdoor unit between seasons, so a check before summer catches that too. A contractor can price the visit for your specific system.
