In Kahului, a heat pump works for cooling almost all the time
Summer afternoons here average 81°F, and winter nights only drop to about 59°F. That is not a cold you need to plan for. A heat pump installed here is going to spend nearly all its time on cooling, month after month, year round.
Because that load never really lets up, the unit you install matters more than it would somewhere with a mild season to rest in. Any split-system heat pump made since January 2023 has to hit 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, and on Maui the cooling side of that rating is the one doing the work all year.

Hawaii requires HVAC contractors to hold a state license.
The license covers the contractor, not the job itself, so it follows the business across every project it takes on. Work under $1,000 does not need a licensed contractor in Hawaii, but a heat pump installation runs well past that, so the contractor doing this job needs to hold the license.
That license tells you who is allowed to do the work. Whether this particular job was done right is checked separately. In most cities and counties, installing a heat pump needs a permit from the local building office and an inspection once the work is done.

- Is a heat pump better than a furnace?
- For a home in Kahului, yes, because a furnace burns fuel to make heat while a heat pump moves heat, and it can also cool your home when you need it to. That matters here since homes need cooling all year and barely need heat at all. A furnace only heats, so you would still need a separate air conditioner to get through the summer afternoons, which average 81°F.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only cools your home. A heat pump does the same job in summer, but it can also run in reverse to bring heat into your home when it's cold outside. The parts inside are almost identical, which is why a heat pump can replace an air conditioner without much change to the rest of the system.
- Does a heat pump work in cold weather?
- Yes, a heat pump pulls heat from outside air even when it's cold, though it works harder as the temperature drops. In Kahului this is rarely a concern, since winter nights average 59°F and homes here need heat 0 months a year. A heat pump sized for this climate will spend almost all its time cooling, not heating.
