When to Call for AC Tune-Up & Maintenance

  • Cooling costs have crept up year over year
  • Air from the vents is weaker than it used to be
  • System has not been serviced in more than a year
  • Outdoor coil is caked with salt, dust or lawn clippings
  • Drain line backs up every wet season
  • You want to protect a manufacturer warranty that requires annual service

What the Service Includes

  • Wash the condenser coil and straighten fins
  • Check refrigerant pressures and superheat/subcooling
  • Test capacitors, contactors and amperage draw
  • Flush the condensate drain and test the float switch
  • Calibrate the thermostat and inspect the blower wheel
  • Written report with photos of anything that needs attention

Hawaii is hard on heating and cooling equipment. Salt-laden trade winds corrode coils and electrical connections, year-round humidity clogs drains and feeds mold, and vog on the Big Island loads filters and coils with fine particulate. Every AC tune-up call we run accounts for those conditions, with corrosion-resistant parts and a written report of what we found.

Customer Reviews

★★★★★

Very thorough. The technician explained what he was checking at each step and left a written report with photos. Signed up for the maintenance plan on the spot.

Chris Y., Hawaii

Our condo building has strict access rules and they handled everything with the resident manager. New air handler installed in a day with no drama.

I called at 10 pm because the unit was making a horrible grinding noise. They were here by 7 the next morning and the fan motor was replaced before lunch. Great communication the whole time.

AC Tune-Up & Maintenance FAQ

How often should an air conditioner be serviced in Hawaii?

At least once a year, and twice a year for oceanfront homes or systems that run year round. Salt air is hard on coils and electrical parts.

Is a tune-up worth it if the AC seems fine?

Yes. A clean coil and a correct refrigerant charge cut power use noticeably, and most compressor failures start as small problems that a tune-up catches.

Do you offer maintenance plans?

We do. Members get scheduled visits, priority booking during heat waves and discounted repairs.
