4,500 BTU (SACC) single-hose portable air conditioner

Fehom KOW60A

Below average efficiency for its size: a CEER of 5.9 beats 2% of the certified 5,000 BTU or less portable air conditioners.

The Fehom KOW60A delivers 4,500 BTU of real cooling (SACC), enough for about 50-100 sq ft, draws about 763 watts and costs about $103 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $44 a year.

A good fit if…

  • You do not want to empty a bucket - it evaporates the water and sends it out through the hose in normal weather.

Think twice if…

  • Running cost matters most - its CEER is below average for 5,000 BTU or less 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 need to cool more than a very small room - this size covers about 100-150 sq ft at most.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Fehom KOW60A.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 Fehom KOW60A cool?
4,500 BTU of real cooling (SACC) suits about 50 to 100 sq ft with normal sun and two people (about 45-90 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 Fehom KOW60A use, and what does it cost to run?
About 763 watts at full power (4,500 BTU/h divided by its CEER of 5.9), roughly 6.6 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $103, which is $6 less than the typical certified 5,000 BTU or less portable unit ($109). Its CEER beats 2% of the 461 certified models in its size class.
Is a one-hose portable air conditioner a problem?
It is the common design: 100% of the certified 5,000 BTU or less models have one hose, with a median of 6.2 CEER. The top-ranked Foshan Hanyang HYAC-TG7 reaches 13.4 CEER.
Do I have to empty the Fehom KOW60A?
Usually not. It evaporates the water it removes and sends it out through the exhaust hose. In very humid weather the pan can still fill, and most units then stop and ask to be drained, so keep a drain hose or a bucket handy.
Can the Fehom KOW60A also heat the room?
No, it only cools. 6 of the 461 certified 5,000 BTU or less portable models can also heat if you want one unit for the year.
Is the Fehom KOW60A as efficient as a window air conditioner?
No. The 3 ENERGY STAR certified window units that cool about as much (within 15% of 4,500 BTU) have a median CEER of 13.7, against 5.9 here, and the best reach 14.4. At 750 hours a year a window unit with that median would cost about $44, $59 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 Fehom KOW60A?
4 certified model numbers from 4 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: 1,007 kWh a yearAn old 9 CEER unit of the same size would cost $106

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).
