What actually decides this purchase
We publish 75 units at 10,000 BTU. They run within $27 a year of each other — but they sell for $351 to $631, a 1.8× spread. Efficiency is not what decides this purchase at 10,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
At $400 this is at or under the 10,000 BTU median of $435, which is the half of the decision that moves real money — every unit at this size runs within $27 a year of every other, so the efficiency ranking below is a tiebreak, not the argument. Worth comparing against the PHILODECO PIWC-10CRD1(ES) at $351 and the Friedrich CCV10A10A at 32 dBA for $588.

3rd cheapest of the 10 units we have a price for at this size (median $435). Checked 2026-10-17.
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.

Efficiency & running cost — computed by Verified HVAC Data
Worth keeping in proportion: every unit in the 10,000 BTU class runs within $27 a year of every other. The gap between the cheapest and dearest to buy at this size is 10× larger. Efficiency is the smallest number on this page, which is why it is not at the top of it.

Frequently asked questions
Is 10,000 BTU right for my room, or should I size up?
About 450 square feet is the guide figure, and 75 certified units sit on that shelf. The next shelf up is 11,000 BTU (4 units), about 450 sq ft. Below it, 9,000 BTU (6 units) covers about 400 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 ELEMENT EHWR10BE fit my window?
Measure your window opening first — it needs to be at least 19" wide (the cabinet width), and the unit is about 14" tall and 20" deep, roughly 46 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.
