For reliable AC not cooling repair in Kaunakakai, Maui homeowners trust UST Air Conditioning. We handle every brand and system type, from ductless mini-splits and heat pumps to central air and packaged units.

We schedule AC not cooling repair in Kaunakakai around your life, with morning, afternoon and evening windows, text updates when the technician is on the way and 24/7 emergency dispatch for the calls that cannot wait.
Maui packs several climates into one island. In Kaunakakai you may be cooling against Kihei-style sun and humidity or heating on a 45-degree Kula night, sometimes in the same week. Heat pumps and mini-splits that do both are the systems we install and repair most.
Our restaurant's rooftop unit failed on a Friday. They came that evening, got us cooling again with a temporary fix and replaced the compressor the following week around our hours.
Michael S., KaunakakaiThey installed a multi-zone ductless system in our home and it changed our summers. The crew was tidy, explained everything and the price matched the quote to the dollar.
Noelani A., KaunakakaiWe had a salt-corroded outdoor unit that finally gave out. UST replaced it with a coated-coil model and explained how to hose it down monthly. Wish we had called them years ago.
Pua L., KaunakakaiNine times out of ten it is low refrigerant from a leak, a failed capacitor keeping the compressor from starting, or airflow so restricted the coil freezes. All three are diagnosed on the first visit.
Refrigerant does not get used up; if it is low there is a leak. Topping off without a repair means paying again next month and risking the compressor.
Turn the system to off (not cool) so a frozen coil can thaw, close blinds on the sunny side and run ceiling fans.
Yes. UST Air Conditioning answers live 24/7 and dispatches emergency technicians throughout Kaunakakai and the rest of Maui for no-cool, no-heat, leaks and electrical problems.
