What size room does the Frigidaire Gallery GHPC142AA1 cool?

10,500 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 Frigidaire Gallery GHPC142AA1 use, and what does it cost to run?

About 840 watts at full power (10,500 BTU/h divided by its CEER of 12.5), roughly 7.3 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $114, which is $58 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 89% 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 Frigidaire Gallery GHPC142AA1?

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 Frigidaire Gallery GHPC142AA1 also heat the room?

No, it only cools. 200 of the 706 certified 10,000 BTU portable models can also heat if you want one unit for the year.

Is the Frigidaire Gallery GHPC142AA1 as efficient as a window air conditioner?

No. The 56 ENERGY STAR certified window units that cool about as much (within 15% of 10,500 BTU) have a median CEER of 15.0, against 12.5 here, and the best reach 17.6. At 750 hours a year a window unit with that median would cost about $95, $19 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.

10,500 BTU (SACC) single-hose portable air conditioner and inverter

Frigidaire Gallery GHPC142AA1

Very good efficiency for its size: a CEER of 12.5 beats 89% of the certified 10,000 BTU portable air conditioners.

The Frigidaire Gallery GHPC142AA1 delivers 10,500 BTU of real cooling (SACC), enough for about 350-450 sq ft, draws about 840 watts and costs about $114 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $95 a year.

Real cooling: 10,500 BTU/h (SACC)For about 350-450 sq ft
Energy use: 630 kWh/yrAbout 840 W, at 750 hours a year
Design: One hose Uses room air for its condenser

A good fit if…

You want low bills - its CEER beats 89% of the 706 certified 10,000 BTU portable models.
You want steadier, quieter running - its variable-speed compressor slows down instead of cycling.
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.
You also need heat - it cools only.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Frigidaire Gallery GHPC142AA1.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.
