NOT A GOOD PRODUCT

Would Not Recommend

Other buyers warned me this unit is poorly built and i didn't listen. Now after 60 days, I'm having to replace parts. This, comes after opening the box and finding a crushed remote control.

Didn't last 2 months

Would Not Recommend

We've had this installed for less than 2 months and the water pump already quit working. Prior to this it worked well, but should last longer than 2 months.

DONT BUY

Would Not Recommend

Do not buy this if you live in California. It’s horrible . We bought this and our house is 79. I retreat selling my old swamp cooler . My old swamp cooler would keep my house at 70 within 10min of turning on . This thing stays on since 7am and keeps my house hot . I regret selling my old one and getting this one thinking it would be an upgrade to our house . You will regret it .

Cooler works, remote never received

Would Not Recommend

This has been frustrating. We are happy with the Cooler itself. If we were writing a review of that alone it would have a better rating. However, in shipping the internal package, containing the remote and the extra plastic pins for the evaporative material, ended up underneath the cooler itself, resulting in the remote being crushed and the pins broken. Okay, that happens. But, over the span of two months we have been trying to get the company to send us replacements. Over three separate ...

float does not work

Would Not Recommend

We have done everything suggested and the float will not shut the inflow of water off NO MATTER WHAT. I am so frustrated with this unit. It will cool my home but the water waste is o overwhelming. Does anyone have any suggestions? This is a new unit.

Cheaply made, very thin plastic

Would Not Recommend

I have 3 of these units, the last one I just got is even cheaper than the ones a couple of years ago. it has taken me hours to get the back cover on because of the cheap plastic that hold the unit up. The options have been limited to 2 fan speeds and on/off. Really!! $650 for this piece of crap!!!

We bought this unit a couple weeks ago and have been very happy with it. Much quieter than the old boxey metal unit we had before as well as more efficient. Keeps the house much cooler

Great swamp cooler! Keeps the main room really coo

Would Recommend

Cools well even at low speed! I got this to replace the exact same model that was very old and only running on one speed. Two plumbers installed it through the wall in my large main room where my old one was and it is working so well. Since the water line was already there it was fairly simple for them to hook up. I highly recommend the Master Cool swamp cooler.

Compacted evaporator cooler

Would Recommend

I have bought these before. They are better than the other ones I had previously bought. The othe evaporator coolers that I bought were big and heavy.
