How efficient is the Gradient CCHP11?

Gradient CCHP11 files CEER 16.8 Btu/Wh. The median among the 19 models in its DOE class (window ACs with heat pump, less than 20,000 BTU/h) is 15.1, so it's above the median: higher than 11 of the 19.

A higher CEER means more cooling per watt.

Who makes Gradient window ACs?

DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.

Its one basic model isn't filed by any other brand as of 2026-11-03, and the model number isn't another company's. DOE's records tie it to Gradient alone.

How much does a Gradient window AC cost to run?

For Gradient CCHP11, DOE's record lists 690 W of electrical input while cooling. That's about 13¢ an hour ($30.07 for 30 days at 8 hours a day).

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.
