  • Great Unit!
Size: 25000 BTU Style: Cool Only 230V Color: Bright White
Installed the 2,500 btu unit in my 1,500 sq ft shop building. Ceiling is twenty foot but insulation is 10" on walls and ceiling. This A/C unit keeps my shop at 76° without any problem even with the outside temps around 100°. Zero problems two years after purchase.

  • Good Quality
Size: 25000 BTU Style: Cool Only 230V Color: Bright White
It's only been a month but most days have been hot ones and this seems to have no problem keeping our double wide mobile home cool, it has been cooling the kitchen, dining and living room areas making them very comfortable despite poor insulation of the trailer and manages to satisfy the unit. Now the question is how long this unit can continue operating on this level, I will update in a few months - good or bad. I believe we made a good choice with this product. Time will tell. Do like that the remote control can control temperature versus the thermostat in the unit, that way the whole area gets cool and not just the area around the unit. Noise level is normal as it is a window unit , you do hear it running as expected nothing crazy & you can't expect it to be whisper quiet and still do it's job, it is a good size unit. ... show more

  • Works great
Size: 25000 BTU Style: Cool Only 230V Color: Bright White
I bought this unit to replace a failed Hisense unit for my shop. So far has worked great. Cools better than the Hisense unit ever did. I have a 1200 square foot shop with twelve foot ceiling height. Keeps shop at 72 degrees with no problem.

  • Keystone 25,000 BTU 230V Energy Star Window/Wall Air Conditioner
Size: 25000 BTU Style: Cool Only 230V Color: Bright White
New AC works fine and cools efficiently as intended. Mounted in a thru-wall area of the den and seems to be a perfect fit per dimensions that were listed for the unit. The dehumidifier function also seems to work very well (even though we have a whole home dehumidifier in the main part of our home) in the extended area of our home (office, hall, den, bathroom- approx. 900+ SF). The unit is a bit noisier than expected, but not so much as to be a hindrance! Overall, very pleased with this unit in the 110+ degree Texas heat! ... show more
