Why us
Window units that seal and drain properly in Honolulu
A window unit that rattles, sweats onto the sill or lets warm air in around the sides was set in a hurry. We spend the time on the parts the box leaves to you: support under the cabinet, side panels pulled tight, foam in every gap, and a drain path that sends water outside. We plug into an outlet that already exists. A new outlet, a dedicated circuit or panel work is a job for an electrician, and mini-splits belong to an HVAC company.
- Room measured before you buy
- Unit supported, not hanging on the sash
- Side panels and gaps sealed
- Drain path checked away from the wall
- Portable AC window kits fitted

Box to cool air
How a window AC goes in
1
Measure
Send the room size, which way it faces, and a photo of the window. We check the opening against the unit before you buy.
2
Quote
A written price per unit, with any support, foam or panel material named, so nothing new turns up on install day.
3
Set it
Unit lifted in, supported under the cabinet, set level or to the maker's tilt, side panels pulled out and fixed to the frame.
4
Seal and test
Gaps foamed, sash secured, unit run until it drips, and the water watched leaving outside, clear of the wall below.
Sizing by room
What size window AC does a room need?
A room needs a window AC sized to its floor area, not the biggest unit on the shelf. ENERGY STAR's chart assumes an 8 foot ceiling and runs from 5,000 BTU per hour for 100 to 150 sq ft, through 9,000 for 350 to 400, up to 12,000 for 450 to 550. Add 4,000 BTU if the unit cools a kitchen. Bigger is not better. A unit matched to the room is the most comfortable and the most efficient, which counts when every kilowatt-hour comes at island prices.
Island cooling
Why do so many Honolulu homes cool with window units?
So many Honolulu homes cool with window units because few were built with central air. The EIA's 2020 residential energy survey counted 12 percent of Hawaii homes on central AC, against 67 percent nationally, while 48 percent used individual units such as window, wall and mini-split types. Trade winds and open jalousies still carry a lot of the load. Then the muggy stretches arrive: lowland humidity runs about 70 to 80 percent on windward sides, and Honolulu's airport logs an average 31.6 days a year at 90 F or above. Power stays expensive, with Hawaii's average home rate at 48.00 cents per kWh in July 2026 by EIA figures, so a leaky seal costs real money.

Sizing, fitting and drainage
A little. ENERGY STAR adds 10 percent for a very sunny room, takes 10 percent off for a heavily shaded one, and adds 600 BTU for each regular occupant past two. Going much bigger than that does not help: a unit matched to the room runs more comfortably and more efficiently.
Sometimes, but it takes more than a standard install. Jalousie louvers do not seal well against drafts or conditioned air even when closed, so the opening around any unit needs careful closing up or the cool air leaks out. We look at the window in person before saying yes, and the jalousie window repair page covers the louvers themselves.
Usually because the water is not draining out. ENERGY STAR says a unit should sit level so its drainage works, though some makers call for a slight outward tilt, and the unit's own manual decides. In June 2025 the CPSC recalled about 1.7 million Midea-made U and U+ window units because pooled water could fail to drain fast enough; the firm knew of at least 152 mold reports. If yours is a U-shaped model, check that recall before anything else.
Yes, we fit the window kit for the exhaust hose and seal the panel against the frame so hot air stays out.
ENERGY STAR says a poorly fitted room unit lets air through like a 6 square inch opening, which is why the insulation pieces in the box should go in, not in the closet.

Condos, power and booking
Check your declaration and house rules first. Under HRS 514B-35, windows that serve only your unit are generally its limited common element unless the declaration says otherwise, and HRS 514B-140 can still require board approval for changes. We read the rules you send before booking.
Into an existing outlet that suits the unit, yes; a new outlet, a dedicated circuit or panel work is a job for an electrician.
ENERGY STAR's advice to pull or cover a unit at season's end is about winter heat loss. With the warmest and coolest months only about 6 F apart on average here, that matters less than keeping the seals tight and the drain clear.
Per unit, in most cases. Two or three rooms in one visit spread the visit minimum, and if you are still shopping, ask before you buy so the size and the window match. The handyman pricing page explains the rest.
