In Kapaa, your AC runs all year and never gets a break
There is no heating season here. Winter nights average 62°F, mild enough that a furnace or heat strip stays off, and summer afternoons reach 83°F, so the air conditioner carries the load twelve months straight. It doesn't get the rest a mainland unit gets in the cooler months. The compressor and the fan run on through what would be the off-season anywhere else, and that steady load is what wears out a capacitor or a contactor early, or leaves a condenser coil dirty enough to choke the airflow.
Kauai County has logged 11 damaging wind events over the last ten years, and 14% of Hawaii households went at least 24 hours without power in 2024. Most air conditioners restart on their own once power returns, but a compressor cut off mid-cycle and started back up over and over takes wear it wouldn't take otherwise.

Hawaii requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued per job. Hawaii's Contractors License Board tests and records the person or company before they take on work like this, and that record stays with them across every job they do, not just this one. Work under $1,000 falls outside that requirement, so a small repair can legally be done without a licensed contractor.
A repair on a heating and cooling system usually runs past that threshold, which means the license is what stands behind whoever does the work. That record is with the Contractors License Board, and it covers the contractor generally rather than this one job.

- Why is my heat not working?
- In Kapaa this is rarely about a furnace, since almost no home here needs one. If a heat pump or electric unit is not warming the house, check that the thermostat is set to heat and not just fan, and check the breaker. Nights only drop to around 62°F here, so a unit that seems weak might just be undersized for the little heating it is ever asked to do.
- Why is my system running but not cooling the house?
- Start with the air filter. A clogged filter blocks airflow across the coil and the house stays warm even though the system runs constantly. Next check the outdoor unit for anything blocking it, like leaves or grass clippings, since it needs open airflow to release the heat it pulls from inside. If the filter is clean and the outdoor unit is clear, the system may be low on refrigerant or have a failing part, and that needs a contractor to diagnose. With afternoons hitting 83°F here, a system that cannot keep up will fall behind fast, so it is worth checking these things as soon as you notice it.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set correctly and has power, whether that means fresh batteries or a breaker that has not tripped. Check the air filter next and replace it if it is dirty, since restricted airflow is one of the most common reasons a system underperforms. Look at the outdoor unit too and clear away anything piled against it. If the power went out, as it does here for some households during storms, give the system a few minutes after power returns before deciding something is wrong. Hawaii requires HVAC contractors to hold a state license issued by the Contractors License Board, so once you have ruled out these basics, a licensed contractor can price the repair for your system.
