10,300 BTU (SACC) single-hose portable air conditioner with heat and inverter

ACHIMCO PAC-A026A-10KRH

Very good efficiency for its size: a CEER of 10.0 beats 76% of the certified 10,000 BTU portable air conditioners.

The ACHIMCO PAC-A026A-10KRH delivers 10,300 BTU of real cooling (SACC), enough for about 350-450 sq ft, draws about 1030 watts and costs about $139 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $93 a year.

A good fit if…

  • You want low bills - its CEER beats 76% of the 706 certified 10,000 BTU portable models.
  • You want steadier, quieter running - its variable-speed compressor slows down instead of cycling.
  • You want one unit for cooling and some heat - it has a heating mode.
  • 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…

  • You want the most efficient design - one-hose units pull warm air in through gaps; dual-hose units lead the efficiency ranks.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the ACHIMCO PAC-A026A-10KRH.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 ACHIMCO PAC-A026A-10KRH cool?
10,300 BTU of real cooling (SACC) suits about 350 to 450 sq ft with normal sun and two people (about 315-405 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 ACHIMCO PAC-A026A-10KRH use, and what does it cost to run?
About 1030 watts at full power (10,300 BTU/h divided by its CEER of 10.0), roughly 9.0 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $139, which is $32 less than the typical certified 10,000 BTU portable unit ($171). Its inverter compressor slows down once the room is cool, so real use is often lower. Its CEER beats 76% of the 706 certified models in its size class.
Is a one-hose portable air conditioner a problem?
It is the common design: 78% of the certified 10,000 BTU models have one hose, with a median of 7.9 CEER. The top-ranked Midea MAP12S1TBL has two hoses and 14.7 CEER.
Do I have to empty the ACHIMCO PAC-A026A-10KRH?
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.
How does the ACHIMCO PAC-A026A-10KRH heat?
It has a heating function, but the DOE data records only that it exists, not whether it is a heat pump or an electric element. Ask the maker: a heat pump gives more heat per kWh than a resistance element, which costs the same as any space heater. 200 of the 706 certified 10,000 BTU models can heat.
Is the ACHIMCO PAC-A026A-10KRH as efficient as a window air conditioner?
No. The 32 ENERGY STAR certified window units that cool about as much (within 15% of 10,300 BTU) have a median CEER of 15.0, against 10.0 here, and the best reach 17.6. At 750 hours a year a window unit with that median would cost about $93, $46 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 ACHIMCO PAC-A026A-10KRH?
3 certified model numbers from 3 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: 1,360 kWh a yearAn old 9 CEER unit of the same size would cost $242

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).
