What size room does the GARVEE KY-8K/07E cool?

4,750 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 GARVEE KY-8K/07E use, and what does it cost to run?

About 766 watts at full power (4,750 BTU/h divided by its CEER of 6.2), roughly 6.7 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $104, which is $5 less than the typical certified 5,000 BTU or less portable unit ($109). Its CEER beats 33% 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 GARVEE KY-8K/07E?

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 GARVEE KY-8K/07E 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 GARVEE KY-8K/07E as efficient as a window air conditioner?

No. The 3 ENERGY STAR certified window units that cool about as much (within 15% of 4,750 BTU) have a median CEER of 13.7, against 6.2 here, and the best reach 14.4. At 750 hours a year a window unit with that median would cost about $47, $57 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.

GARVEE KY-8K/07E

Below average efficiency for its size: a CEER of 6.2 beats 33% of the certified 5,000 BTU or less portable air conditioners.

The GARVEE KY-8K/07E delivers 4,750 BTU of real cooling (SACC), enough for about 50-100 sq ft, draws about 766 watts and costs about $104 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $47 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 GARVEE KY-8K/07E.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.
