      7,000 BTU (SACC) single-hose portable air conditioner

      Antarctic Star AC7207-7K

      Below average efficiency for its size: a CEER of 6.9 beats 1% of the certified 8,000 BTU portable air conditioners.

      The Antarctic Star AC7207-7K delivers 7,000 BTU of real cooling (SACC), enough for about 150-300 sq ft, draws about 1014 watts and costs about $137 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $63 a year.

      A good fit if…

      • You want a certified 7,000 BTU (SACC) single-hose portable air conditioner at a typical efficiency level.

      Think twice if…

      • Running cost matters most - its CEER is below average for 8,000 BTU portable air conditioners.
      • You want the most efficient design - one-hose units pull warm air in through gaps; dual-hose units lead the efficiency ranks.
      • You also need heat - it cools only.
      • You want no drain to deal with - it uses a gravity drain you must run to a floor drain or a bucket.

      These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Antarctic Star AC7207-7K.They may be the same unit sold under several brands, or different products that test the same: the DOE data has no dimensions or noise figures, so check those with the maker. Ratings within about 2% in capacity and 0.3 in CEER are treated as the same; a model whose own rating differs a little shows it in brackets.

      Questions7
      What size room does the Antarctic Star AC7207-7K cool?
      7,000 BTU of real cooling (SACC) suits about 150 to 300 sq ft with normal sun and two people (about 135-270 sq ft if very sunny), by the ENERGY STAR floor-area table. Size by SACC, not the larger BTU on the box.
      How many watts does the Antarctic Star AC7207-7K use, and what does it cost to run?
      About 1014 watts at full power (7,000 BTU/h divided by its CEER of 6.9), roughly 8.8 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $137, which is $11 less than the typical certified 8,000 BTU portable unit ($148). Its CEER beats 1% of the 710 certified models in its size class.
      Is a one-hose portable air conditioner a problem?
      It is the common design: 92% of the certified 8,000 BTU models have one hose, with a median of 7.3 CEER. The top-ranked Hisense HIAP0825TWD has two hoses and 13.5 CEER.
      How does the Antarctic Star AC7207-7K handle the water it removes?
      It drains by gravity: you run a hose from the unit to a floor drain, a sink or a bucket that stays lower than the unit. Do not coil the hose or lift it above the outlet.
      Can the Antarctic Star AC7207-7K also heat the room?
      No, it only cools. 146 of the 710 certified 8,000 BTU portable models can also heat if you want one unit for the year.
      Is the Antarctic Star AC7207-7K as efficient as a window air conditioner?
      No. The 34 ENERGY STAR certified window units that cool about as much (within 15% of 7,000 BTU) have a median CEER of 15.0, against 6.9 here, and the best reach 16.0. At 750 hours a year a window unit with that median would cost about $63, $74 less than this one. ENERGY STAR window units are the more efficient part of the window market, so the gap to an average window unit is smaller. A portable unit makes sense when a window unit will not fit or is not allowed.
      Which model numbers have the same ratings as the Antarctic Star AC7207-7K?
      6 certified model numbers from 6 brands share these ratings: capacity, CEER, hose design, heating, drain type and compressor. They may be the same unit under different brands, or different products that test the same; the DOE data does not include dimensions or noise, so check those with the maker.

      Electricity used: 1,339 kWh a yearAn old 9 CEER unit of the same size would cost $164

      Power draw is capacity divided by CEER, which already includes standby power. Inverter units often run below full power, so real use can be lower. Electricity prices: U.S. EIA residential averages (12 months to July 2026). Days a year start from your state's cooling degree days (NOAA 1991-2020 normals).
