A window AC is a self-install unit: you set it in the window (or wall sleeve), no contractor or refrigerant charge needed. We verified this listing against the certified record: same brand, the same 15,000 BTU cooling capacity, the same window AC form factor, and in stock at the price shown. Its title doesn’t carry this model number, so treat it as the current equivalent rather than a guaranteed identical SKU.
Sized for ~750 sq ft — measure your room and check your window type before you buy.

Efficiency & running cost — computed by Verified HVAC Data
Worth keeping in proportion: every unit in the 15,000 BTU class runs within $43 a year of every other. The gap between the cheapest and dearest to buy at this size is 5× larger. Efficiency is the smallest number on this page, which is why it is not at the top of it.

Frequently asked questions
Is 15,000 BTU right for my room, or should I size up?
About 750 square feet is the guide figure, and 7 certified units sit on that shelf. The next shelf up is 18,000 BTU (17 units), about 900 sq ft. Below it, 14,000 BTU (33 units) covers about 700 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.
Will the Whirlpool WHAW-151IN fit my window?
Measure your window opening first — it needs to be at least 30" wide (the cabinet width), and the unit is about 21" tall and 29" 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.
