Rated 4.2 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by Great Unit Energy efficient, strong fan and output. The legs worked well and the installers/installation was good but not great. There is a seal incomplete that the roofers will have to seal when the new roof is installed in the beg of October. All around---HD service/personnel, at every level, was exceptional and the installation was good. The unit itself works perfect for our home's design and 1750 sq ft main floor which receives the bulk of the cooling air. October 13, 2014
Rated 4.0 out of 5.0 by Quiet, so far so good.... Everything went together nicely. You can actually take the unit apart and haul it up a roof if need be. Mine was sort of destroyed when I got it unboxed at home. It was going to be too much of a hassle to take back. Although it does look bad, it works, too bad I don't have all the time int the world to exchange it. Seems to get cool quick though and would have got a 5 star except for the damage and you have to buy a motor...but it is quiet and hope it don't rust...! May 17, 2012
Rated 5.0 out of 5.0 by Home Cooling The Mastercool 5000 CFM is perfect for my 1600+ square foot home. When operating, it is whisper quite. I don't believe you could get a better cooling unit for the same price. May 22, 2012
Rated 5.0 out of 5.0 by Very well designed and built I am happy that I decided to spend the extra $ for this model vs the old style "Aspen Pad" coolers. June 26, 2012
Rated 4.0 out of 5.0 by NEED BETTER QUALITY CONTROL We took the box apart to remove the cooler first thing we noticed the top was damaged . second thing trying to get the panels off were difficult due to the screws all being over torqued and stripped they would just spin doesnt come with any hardware to anchor it to the roof top.. we used the 3/4 horse motor and the unit is very noisy ....

Rated 2.0 out of 5.0 by Works as good as my last one. Works just as good as my last one. Unit is not square so the grill wouldn't sit level enough to hold it in. Had to use screws to hold the grill on. Also the grill was bent into the pads during shipping. March 12, 2014
