What actually decides this purchase
We publish 73 units at 8,000 BTU. They run within $15 a year of each other — but they sell for $260 to $570, a 2.2× spread. Efficiency is not what decides this purchase at 8,000 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 8,000 BTU the field runs $260 to $570, median $354, and every one of them runs within $15 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 24th of 73 in its class. If the price you are quoted is above $354, buy something else. Worth comparing against the TCL H8W4KW at $260 and the Friedrich CCV08A10A at 32 dBA for $519.
Price
Not tracked
We have no verified retail listing for this certificate. Units at this size run $260–$570.
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.

Frequently asked questions
Is 8,000 BTU right for my room, or should I size up?
About 350 square feet is the guide figure, and 73 certified units sit on that shelf. The next shelf up is 9,000 BTU (6 units), about 400 sq ft. Below it, 6,000 BTU (17 units) covers about 250 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 Keplerx KARC8RSVE1 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 44 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.
