San Rafael doesn't ask much of an air conditioner
Summer afternoons here average 71°F. That's mild enough that a lot of homes barely run the compressor at all most days. An air conditioner that sits idle for long stretches isn't wearing out from use, but it's not immune to the weather outside the unit.
Marin County has logged 122 damaging wind events and 11 hail storms over the past ten years. Wind drives debris into the outdoor coil and can rock the unit on its pad. Hail here has stayed small, up to a quarter inch, but even that can dent thin fins over time. A tune-up is where a contractor checks the coil, the fins, and the cabinet for that kind of buildup or damage before it affects how the unit runs when you do need it.

California requires HVAC contractors to hold a state license.
The Contractors State License Board tests and records the contractor, not the individual crew member who shows up at your house, and not each job that contractor takes on. That license is tied to the business itself, so it stays in place across every job that business does in the state.
For AC maintenance, the license is what stands behind the work. If the technician opens the refrigerant side of your system to check the charge or look for a leak, federal law also requires EPA Section 608 certification, and that rule applies the same way in every state, not just California.

- What does AC maintenance include?
- A technician checks refrigerant levels, cleans the condenser coil, tests the capacitor and inspects electrical connections. They also check the thermostat calibration and make sure the condensate drain isn't clogged. In San Rafael, summer afternoons average around 71°F, so the system rarely runs under heavy strain, but the coil still collects dust and debris over time and the electrical parts still wear.
- How often does an air conditioner need maintenance?
- Once a year is standard for most air conditioners. That holds true even in a mild climate like San Rafael's, where summer highs average 71°F and the unit isn't working hard most days. A yearly check still catches a weak capacitor or a dirty coil before it causes a breakdown.
- Is AC maintenance worth it?
- Yes, because it catches small problems, a failing capacitor, a low refrigerant charge, before they turn into a system that won't turn on. It also keeps the coil clean, which helps the unit cool efficiently. A contractor can look at the specific system and tell you what shape it's in.
