Sea Breeze WA324ZREB
window air conditioner · 24,000 BTU cooling · fits ~1,200 sq ft
A window AC rated 24,000 BTU — enough cooling for a room of roughly 1,200 square feet (the 20-BTU-per-square-foot rule).
What actually decides this purchase
We publish 22 units at 24,000 BTU. They run within $38 a year of each other — but they sell for $635 to $1,115, a 1.8× spread. Efficiency is not what decides this purchase at 24,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
We have no tracked price for this unit, so here is the rule instead. At 24,000 BTU the field runs $635 to $1,115, median $635, and every one of them runs within $38 a year of every other — so price is the decision and efficiency is the tiebreak. On the certified specs we do hold, this one ranks 6th of 22 in its class. If the price you are quoted is above $635, buy something else. Worth comparing against the Midea MAW24R2VWT at $635 and the Friedrich CCV24A30A at 32 dBA for $1,115.
Price
Not tracked
We have no verified retail listing for this certificate. Units at this size run $635–$1,115.
Noise
Not published
The maker publishes no dBA figure we could verify, and noise is not part of the DOE certification. It is the most common complaint about window units, so treat its absence as a real unknown.

A window AC is a self-install unit: you set it in the window (or wall sleeve), no contractor or refrigerant charge needed. We have not matched a retail listing for this exact model, so we are not linking one. Search your usual retailer for the model number above — and check the certified specs here against whatever you find.

Efficiency & running cost — computed by Verified HVAC Data
Worth keeping in proportion: every unit in the 24,000 BTU class runs within $38 a year of every other. The gap between the cheapest and dearest to buy at this size is 13× larger. Efficiency is the smallest number on this page, which is why it is not at the top of it.

Frequently asked questions
Is 24,000 BTU right for my room, or should I size up?
About 1,200 square feet is the guide figure, and 22 certified units sit on that shelf. Below it, 18,000 BTU (17 units) covers about 900 sq ft. Between two shelves, take the smaller one: oversizing is the usual reason a unit cools but leaves the room clammy, which our sizing calculator explains.
Does the Sea Breeze WA324ZREB need a special outlet?
Yes. It runs on 230 volts, not the 115-volt outlet a bedroom or living room normally has, so it needs a dedicated circuit installed by an electrician. Budget for that before you buy: most units in its 24,000 BTU class are 115-volt, so a same-size alternative may avoid the wiring entirely.
Will the Sea Breeze WA324ZREB fit my window?
Measure your window opening first — it needs to be at least 24" wide (the cabinet width), and the unit is about 18" tall and 25" deep, roughly 103 lb. Most double-hung windows fit units in this range with the included side panels, but confirm your window's inside width and minimum height.
Sources. Certification and CEER from ENERGY STAR room-AC data and the DOE compliance certification database. Cooling capacity, dimensions and refrigerant are the manufacturer-certified values. Annual running cost, suggested room size and the percentile are computed by Verified HVAC Data from published ratings and EIA U.S. average electricity prices — see our methodology. Refrigerant GWP is the IPCC value. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
