Rated 4.3 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by MasterCool Evaporative Cooler a Top Notch Unit Wonderful unit - far superior to the model it replaced. (and worth the extra $600). Much quieter and the thermostat is great - slows the fan down when the set temperature is being reached - and speeds it up as needed. When temperature setting is met, unit turns off - just like a compressor style unit. Construction quality is good, and it is made in the USA with some imported components. <sigh> The plastic water tray and media housing will reduce the corrosion, and I hope will increae the life too. After the installation, I liked the lower profile - it is more difficult to see on the roof. April 18, 2010
Rated 5.0 out of 5.0 by I believe it to be one of the best coolers for our area Your information on your product is extensive and has the information needed to make the decision on what you actually need August 7, 2013
Rated 5.0 out of 5.0 by 30 years in place Thirty years of in place service. While our neighbors enjoy $400.00 electrical bills ours seldom exceeds $150.00 even during the hottest months. The water box retired after 25 years and was replaced with a Master cool unit at no great expense. Same with the motor but 25 summers in California will put a load on any unit. We stuck with the MC original equipment even though a bit pricey. We have used these units in the home, shop and office and all perform better than any in the neighborhood. TJE May 19, 2015
Rated 5.0 out of 5.0 by Very Good Evaporative Cooler Put it in as a DIY, and while it requires a sturdy base, the cool air output was/is outstanding. Much more efficient that the traditional wet box; time will tell how the separate wet section holds up, but it just makes sense to have it all in plastic. Electrical hook up was a breeze.

Rated 5.0 out of 5.0 by Mastercool Swamp Cooler Wow I highly recommend the Mastercool evaporative coolers such as the ADA7112. This unit will be the one I will save for and purchase as a replacement unit, due to the fact that it has more features than my current Champion evaporative cooler that needs replacement. Features include much better air quaility, a better cooling ratio of 5-10 degrees, less power used and the ability to run off of a thermostat. The savings for the unit amount to over $1800.00 as compared to buying the unit from a heating and cooling company. August 19, 2010
Rated 2.0 out of 5.0 by Good specs, poor quality Unit arrived with a few minor dents from shipping. After hauling it up on the roof and installing it I found that the blower unit had a big dent in it and had been installed in the cabinet crooked. Also, the squirrel cage was misaligned in the housing with a gap on one side large enough to put my hand in it. These problems were due to poor construction at the factory, not mishandling during shipping. May 16, 2011
Rated 4.0 out of 5.0 by Good for cooling house, PAIN to maintain I've had the unit for 3 summer seasons now. DIYA installed, not a big deal. Water and electrical hookups were straight forward. Have the 1HP motor to really move air. As far as what it's made for…it does a GREAT job of cooling the house, even on low. Far superior to our old 4-sided downdraft evaporative cooler. I ***HATE*** the start up and tear down of this thing in the spring and fall. It's such a HUGE PAIN IN THE BUTT to get into. If I want to fully access the water tray to clean out the dirt and minerals, or the pads, I have to take off the full cover of the unit to do so! The side panels remove easily by the fly-wheel, so I can easily unplug the pump and blower motor and reach in for the water valve…but to remove the side panels where the water tray and pads are…I hate it. This could have been remedied with a better design, but it wasn't so now I find myself wanting to pay someone else to get up there, except I doubt they would take the top off to thorough clean and prepare the unit for the summer cooling or winterization.

Rated 4.0 out of 5.0 by Has great features. Other than having issues with the condition of the unit when it was delivered once to the store and the 2nd time to the house. Both times it came with dents and bends where they should not have them. The unit cools our 1900 sq ft home very well! July 31, 2013
