How much is the diagnostic service fee?

We provide a $0 Free Clean-vs-Replace Assessment and custom itemized quote that covers on-site technician dispatch, travel time, and a comprehensive electrical and mechanical troubleshooting evaluation. You receive an upfront, itemized repair or replacement recommendation before any physical work begins.

What if my Window AC unit is too old or expensive to repair?

If your compressor is grounded/seized or your unit is over 5–7 years old with extensive salt-air coil corrosion, repair costs can exceed the value of the unit. Because Affordable Home AC maintains its own Waipahu warehouse, we can immediately offer in-stock LG Dual Inverter and GE Built-In window AC replacements ($395–$1,200) with same-day/next-day pickup by appointment or $50 flat Oahu delivery.

Do you service both window-mounted and through-the-wall AC units?

Yes. Our technicians service and replace both standard/jalousie-mounted LG Dual Inverter window air conditioners and 26-inch GE Built-In through-the-wall chassis across Honolulu, Pearl City, Waipahu, Kailua, and all Oahu.

Why Window Air Conditioners Fail on Oahu

Salt-Air Corrosion

Coastal trade winds carry airborne salt across the island, rapidly oxidizing aluminum condenser fins and pitting copper tubing, resulting in pinhole micro-leaks.

Control Board & Capacitor Wear

High ambient heat and humidity place heavy thermal loads on start/run capacitors and inverter control boards during peak summer cooling cycles.

Algae Drain Pan Blockages

Warm 74%+ relative humidity incubates thick algae biofilm inside window AC slinger pans and drain channels, causing water to back up and drip indoors.
