Kapaa Customers on Our HVAC Installation

★★★★★

Heat pump stopped heating on a cold Volcano night. The technician walked me through a reset on the phone first, then came out the next day to replace the defrost board. Really appreciated not being charged for an unnecessary trip.

Jason L., Kapaa
★★★★★

Duct cleaning and sealing after our renovation. The dust problem is gone and the system is quieter. Crew was careful with the floors and furniture.

Leilani K., Kapaa
★★★★★

New heat pump installed for our upcountry home. It cools in the afternoon and heats on the cold nights, and our electric bill is lower than with the old space heaters.

HVAC Installation & Replacement in Kapaa: Questions We Hear Most

How much does a new HVAC system cost in Hawaii?

It ranges widely by size and type. A single-zone mini-split is the most affordable; a whole-home ducted heat pump is the largest investment. We give fixed written quotes.

How long will a new system last?

With annual maintenance, 12 to 15 years even in salt air; coated coils help coastal homes reach the upper end.

Do you pull permits?

Yes, we handle county permitting and inspections as part of the installation.

Can you service my vacation rental in Kapaa?

Absolutely. We work with owners and property managers across Kauai, coordinate with guests and cleaners, and send invoices and reports directly to you.
