10,800 BTU (SACC) single-hose portable air conditioner with heat
Moxeay MY1222
Very good efficiency for its size: a CEER of 8.1 beats 71% of the certified 10,000 BTU portable air conditioners.
The Moxeay MY1222 delivers 10,800 BTU of real cooling (SACC), enough for about 400-450 sq ft, draws about 1333 watts and costs about $180 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $97 a year.

A good fit if…
- You want low bills - its CEER beats 71% of the 706 certified 10,000 BTU portable models.
- 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.

Model numbers with these ratings
These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Moxeay MY1222.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.

Questions
- What size room does the Moxeay MY1222 cool?
- 10,800 BTU of real cooling (SACC) suits about 400 to 450 sq ft with normal sun and two people (about 360-405 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 Moxeay MY1222 use, and what does it cost to run?
- About 1333 watts at full power (10,800 BTU/h divided by its CEER of 8.1), roughly 11.6 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $180, which is $9 more than the typical certified 10,000 BTU portable unit ($171). Its CEER beats 71% 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 Moxeay MY1222?
- 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 Moxeay MY1222 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 Moxeay MY1222 as efficient as a window air conditioner?
- No. The 59 ENERGY STAR certified window units that cool about as much (within 15% of 10,800 BTU) have a median CEER of 15.0, against 8.1 here, and the best reach 17.6. At 750 hours a year a window unit with that median would cost about $97, $83 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.
