Frequently asked questions
Is 28,300 BTU right for my room, or should I size up?
About 1,415 square feet is the guide figure. Below it, 24,000 BTU (22 units) covers about 1,200 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 Kühl+ KHVL28B35B 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.
Does the Kühl+ KHVL28B35B heat as well as cool?
Yes — it is certified with a heating mode, so it works as a shoulder-season heater as well as an air conditioner. Only 30 of the 389 room ACs we publish do. It is supplemental heat for one room, not a replacement for a home heating system.
Will the Kühl+ KHVL28B35B fit my window?
The certification record doesn't publish reliable full dimensions for this unit, so measure your opening and compare against the seller's listing before you buy.
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.
