Buy this unit
No verified online listing
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.
Sized for ~530 sq ft — measure your room and check your window type before you buy.
At a glance
Who it's for
Cooling a single room of about 530 sq ft — a bedroom, office or apartment — that you install yourself, no contractor.
The standout number
CEER 15 — the room-AC efficiency number; higher means a lower summer electric bill.
The catch
Window units only fit windows in their size range — measure your window width and height against the dimensions below before you buy.

Rebates & incentives
This unit meets ENERGY STAR Most Efficient, the top room-AC tier some utility rebates require. The federal 25C credit expired December 31, 2025, and it never covered room ACs anyway; the live money is state and utility programs. Check what applies where you live on our rebates page.

Frequently asked questions
What size room does the Kühl+ KHVS10B11B cool?
It puts out 10,600 BTU of cooling. The common rule of thumb is 20 BTU per square foot, so it suits a room of about 530 square feet with 8-foot ceilings. Sunny rooms, kitchens or spaces with many people need a bit more; heavily shaded rooms a bit less.
How efficient is the Kühl+ KHVS10B11B?
It is rated CEER 15. CEER (Combined Energy Efficiency Ratio) is the DOE test number for room air conditioners — the higher it is, the less electricity the unit uses for the same cooling. This model uses about 53% less energy than the federal minimum for its size.
What does the Kühl+ KHVS10B11B cost to run?
We estimate about $100 a year to run it — roughly 530 kWh, at U.S. average electricity prices and a typical cooling season. Your climate and local power price move the number; running it fewer hours costs less.
Will the Kühl+ KHVS10B11B fit my window?
Measure your window opening first — it needs to be at least 26" wide (the cabinet width), and the unit is about 16" tall and 29" deep, roughly 105 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.
Where can I buy the Kühl+ KHVS10B11B?
Room air conditioners are self-install and sold online. Our "Find it on Amazon" button opens a live search for this exact brand and model so you can compare current prices and sellers. It sets in the window (or wall sleeve) yourself — no contractor and no refrigerant charge.
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.
