Your AC runs every month of the year here

In Honolulu County there's no season off. Summer afternoons average 85°F, and the system runs twelve months to keep up with it. That kind of nonstop demand adds up on the compressor and the run capacitor, the parts that carry the load every time the unit cycles on.

Wind is the other thing this place deals with. The area has logged 58 damaging wind events over the past ten years. Wind that strong can rock an outdoor unit, strain its refrigerant lines, or throw debris into the coil and fins. If your AC is struggling now, either of these is a reasonable place to start looking.

A new air conditioner would cut about $170 a year off cooling for a typical Honolulu County home.

  • A new one at the federal minimum, 14.3 SEER2$1,120 a year
  • An older air conditioner$1,290 a year

Estimates for a typical Honolulu County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Hawaii fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when a part like a capacitor or contactor has failed.

Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.

Hawaii requires HVAC contractors to hold a state license.

The state's Contractors License Board tests and records the contractor, not the job. That license follows the business, so it covers your repair without being issued for it specifically. If the repair comes in under $1,000, Hawaii does not require a licensed contractor for it at all.

For an air conditioner repair, the license is what stands behind the work here. Alongside it, anyone opening the refrigerant side of your system, in Hawaii or any other state, has to hold EPA Section 608 certification. That's a federal rule, separate from the state license, and it applies regardless of the size of the job.

Why is my AC not blowing cold air?
The most common reason is a dirty air filter choking off airflow across the coil. When that happens the coil can ice up, and once it's iced over the air coming through the vents turns warm or weak. Low refrigerant from a leak is another common cause, and that needs a licensed contractor since only someone with EPA 608 certification can open the refrigerant side of the system. With cooling needed here most of the year, it's worth checking the filter first since that's the one thing you can rule out yourself.
Why is my AC leaking water?
Usually the drain line has clogged with algae or dirt and the water is backing up instead of draining outside. It can also mean the coil has iced up and is now melting and overflowing the drain pan. A dirty filter or low refrigerant can cause that icing, so the water is often a sign of one of those problems rather than the main issue itself. If the pan or drain line itself has cracked or rusted through, that part will need replacing.
Why won't my AC turn on?
Start with the thermostat batteries and the breaker before assuming the worst. If the breaker keeps tripping, that points to an electrical problem inside the unit and it shouldn't be reset repeatedly. Outdoor units also have their own disconnect switch nearby, and it's worth checking that it hasn't been bumped off. If power and the thermostat check out and it still won't start, the capacitor or the compressor itself may have failed, and that's a job for a licensed contractor to diagnose.
