Questions5
What is the best 6,000 BTU portable air conditioner?
On certified efficiency, 6,450 BTU single-hose portable AC, 7.4 CEER at 7.4 CEER, about $118 a year at typical U.S. use. The typical certified unit in this size has 6.6 CEER.
How big a room does a 6,000 BTU portable air conditioner cool?
About 150 to 250 sq ft for a unit that really delivers 6,000 BTU (SACC), with normal sun and two people, following the ENERGY STAR floor-area table. A box marked 8,500 BTU can certify at 6,000 SACC: the larger number is the older ASHRAE rating, not what the unit delivers. In a very sunny room use about 10% less area; a kitchen needs about 4,000 BTU more.
How many watts does a 6,000 BTU portable air conditioner use?
Between 822 and 986 watts at full power for certified models, about 909 W for the typical one. That is about $123 a year at 750 hours and 18.0¢/kWh.
Is a dual-hose 6,000 BTU portable air conditioner worth it?
No certified unit in this size has two hoses; all 458 models are single-hose. For two hoses you need a unit of 8,000 BTU or more.
Is a portable air conditioner of this size as efficient as a window unit?
No. The 9 ENERGY STAR certified window units that cool about as much have a median CEER of 15.1, against 6.6 for the typical portable unit here, so the window unit costs about $54 a year to run against $123. A portable unit is the answer when a window unit will not fit.
