Window AC Weather Stripping & Island Seal Oahu

A high-efficiency air conditioner is only as good as the seal around it. Cheap factory foam strips dry out under Oahu’s UV rays, leaking expensive cooled air and letting in rain, trade wind dust, and geckos. Our high-density closed-cell sealing locks your cool air inside.

Expensive Cold Air Leaks

Drafts around accordion curtains force your unit to run overtime on Oahu’s ~44.2¢/kWh tariff, wasting up to $40/month in lost electricity.

Geckos & Island Insects

Gaps as thin as 1/8 inch are highway corridors for geckos, mosquitoes, and centipedes crawling in from outside garden foliage.

Tropical Rain Intrusion

Driving trade wind rains can soak interior window sills, rotting wood framing and promoting toxic black mold growth behind drywall.

PROFESSIONAL INSTALLATION BENEFIT

Marine-Grade Closed-Cell Foam

When our Oahu cooling technicians install your window AC, we don’t use flimsy paper-thin factory foam. We install durable, UV-stabilized closed-cell neoprene gaskets and custom insulated backer panels that resist tropical humidity and trade wind pressure.

Clean Jobsite Standard: Our technicians lay clean floor drop cloths under every window and leave your home cleaner than when we arrived.

Insured Oahu Cooling Specialists

Expert weather sealing included with all professional window AC installations across Oahu.

Weather Sealing FAQs

Unsealed window gaps allow chilled air to escape and hot humid trade winds to blow in, forcing your AC to run continuously and driving up your HECO bill. Gaps also invite geckos, ants, and flying insects inside.
