The technician found that our ducts were leaking into the attic, which explained the hot back bedroom. Sealing them made a bigger difference than I expected and our bill dropped noticeably.
Noelani A., Hawaiian BeachesCalled three companies for an installation quote. UST was not the cheapest but they were the only ones who measured the house and did a load calculation. The system is perfectly sized.
Chris Y., Hawaiian BeachesThermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.
Brandon T., Hawaiian BeachesSome do, especially at elevation and on windward slopes where winter nights drop into the 50s. Heat pumps and mini-splits in heat mode are the most efficient way to add heat.
Salt and humidity corrode electrical parts and coils, and dirty coils make the compressor overheat during the hottest weeks. A spring tune-up prevents most of these breakdowns.
Most common repairs, such as capacitors, contactors, drain clearing and fan motors, fall in a modest flat-rate range that we quote before starting. Larger repairs like compressors or coils are priced against replacement so you can decide. There are no hidden fees.
Same day for most repair calls and within hours for emergencies. Call (855) 459-5498 and the dispatcher gives you a real arrival window.
If the system is under 10 years old and the repair costs less than a third of a new system, repair usually makes sense. Older R-22 systems and units with salt-damaged coils are usually better replaced.
