Horizontal Sliding Window AC Installation Oahu
Most Oahu townhomes and modern subdivisions feature horizontal sliding windows rather than traditional sash windows. Our Oahu cooling technicians fabricate custom vertical filler panels and install standard exterior support brackets for a flawless, weather-tight installation.
Vertical Filler Panels
We precision-cut clear acrylic or insulated rigid foam to seal the open vertical channel above the unit cleanly.
Standard Exterior Brackets
Transfers the unit’s heavy cantilever weight to the outer building sill, completely protecting delicate vinyl sliding tracks.
Weather & Gecko Seal
Closed-cell perimeter foam prevents tropical moisture intrusion, wind drafts, and island insects from entering your home.
Protective Drop-Cloth Standard
Our experienced technicians treat your home with the utmost respect. We lay clean floor drop cloths under every window opening during installation and clean up all debris, leaving your home spotless.
