Your heat pump works every month of the year here
In Kahului there's no winter to give it a break. Summer afternoons average 81°F and winter nights only drop to 59°F, so the system is moving heat out of the house every day of the year. That kind of nonstop run time wears on the compressor and the fan motor faster than a system that gets to rest part of the year.
Power matters too. Maui County sees damaging wind often enough to knock the grid out, and statewide, 14% of households lost power for a full day or more in 2024. A heat pump that cuts out in a storm doesn't always come back cleanly on its own, and that shows up as a unit that runs but won't cool, or won't start at all.

Hawaii requires HVAC contractors to hold a state license.
The Contractors License Board tests contractors before licensing them, and that license belongs to the contractor, not to any one job. It stays on record no matter what the work is. Work under $1,000 falls outside that requirement, so a small fix may not need a licensed contractor at all.
A heat pump repair means opening the refrigerant side of the system. That calls for something the state license does not cover. Anyone handling refrigerant must hold EPA Section 608 certification, a federal requirement that applies in every state. It has nothing to do with the Contractors License Board. It exists because refrigerant itself is regulated by federal rule, and the technician handling it has to be certified for that, separate from whatever the state requires.

- Why is my heat pump blowing cold air?
- In Kahului your heat pump runs as an air conditioner most of the time, so cold air out of the vents usually means it is doing its job. If the air feels warmer than it used to, or barely cool at all, check the filter first since a clogged one starves the coil of airflow. If the air is cold but the house never gets comfortable, or you hear the outdoor unit struggling, the refrigerant charge or the compressor may be the issue, and that needs a licensed contractor to look at.
- Why is there ice on my heat pump?
- Ice on the outdoor unit usually means airflow across the indoor coil is restricted, often by a dirty filter or a coil that needs cleaning. It can also mean the refrigerant charge is low, which drops the coil temperature below freezing and pulls moisture from the air onto the coil. Do not chip the ice off. Turn the system off, let it thaw fully, and have a contractor find out why it formed, since low refrigerant means someone with EPA 608 certification has to open the system to check it.
- Why is my heat pump running but not cooling?
- If the outdoor and indoor units are both running but the house isn't cooling, warm air is either not moving through the ducts properly or the refrigerant side isn't doing its job. Start with the filter and any vents that might be blocked. If those are clear, the problem is likely low refrigerant, a failing compressor, or a blocked coil, and diagnosing which one it is means opening the sealed system, which by federal law only a technician with EPA Section 608 certification can do. With summer afternoons in Kahului averaging 81°F, a heat pump that isn't cooling is worth getting looked at quickly.
