Five months of Nogales heat, and the storms in between
Your air conditioner works from May through September here, with summer afternoons averaging 90°F. That is the stretch where it runs longest and hardest, cycling on again and again to keep up. A tune-up before that stretch checks the parts that wear from long runtimes, the capacitor, the contactor, the condenser coil, so they hold up through the months you need them most.
Santa Cruz County has also seen 53 damaging wind events and 16 hail events over the past ten years, with hail up to 1.75 inches. Wind can rock an outdoor unit and loosen electrical connections. Hail can dent the condenser coil's fins, which slows the airflow it needs to cool the refrigerant. A service visit after a storm season catches that kind of damage before it turns into a system that runs but cannot keep the house cool.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Arizona requires HVAC contractors to hold a state license.
That license is issued to the contractor, not to each job, so it is the business and the person running it that Arizona has on record, tested and accountable, not the specific maintenance visit to your air conditioner.
For this job, the state license is what stands behind the work. If the technician opens the refrigerant side of your system to check the charge, they also need EPA Section 608 certification, which is a federal requirement in every state, not something Arizona adds on top.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil outside and the evaporator coil inside, and tests the capacitor and contactor that get the compressor and fan running. They check the condensate drain for clogs, since a blocked drain backs up and can shut the system down or cause water damage. They also check the filter, since a dirty one restricts airflow across the coil and makes the system work harder to cool the same air.
- How often does an air conditioner need maintenance?
- Once a year, ideally in spring before the heat sets in. Nogales runs hot from May through September, with afternoons averaging 90°F, so the system runs most days for five straight months. A check before that stretch begins catches a weak capacitor or a low refrigerant charge while it is still a simple fix.
- Is AC maintenance worth it?
- Yes. A system that runs five months straight through 90°F afternoons depends on a clean coil, correct refrigerant charge, and good electrical connections to keep up with that load. Skipping maintenance lets small problems, like a weak capacitor or a dirty coil, turn into a breakdown on the hottest day of the year.
