  • Great buy
Size: 12000-115
I replaced a dud of a unit from Pioneer with this one, and was not sure what to expect since it was priced lower. The install went smoothly and the instructions were accurate. The prior unit always lagged behind and the room temp stayed a few degrees above set point. The Mountman keeps the room right where it is set. I am very happy so far. ... show more

  • Works Great Easy To Install
Size: 12000-115
Unit install is really easy. works as it should i purchased the unit and didn't realize the line set was very short, sent a message to the seller and they sent me a longer line set and wire at no additional cost. if i need to buy another i will buy this brand again. Thank You

  • Works Great!
Size: 12000-115
The system cools effectively, is quiet both inside and outside, and, so far, seems very energy-efficient to operate. The installation requires special equipment. I would recommend professional installation if you do not have moderate experience with electrical work, tools, or vacuum systems.

  • The Best Solution for Stuffy Rooms
Size: 12000-115
It works great! I should have bought this years ago—after all, our main air conditioner has never been able to cool the whole house. With one-touch control via the remote, it runs only when needed, saving on electricity bills.

  • High-quality product
Size: 12000-115
It didn’t disappoint. Installation was a breeze, and its performance lived up to expectations. This air conditioner cools down quickly, keeping my entire garage refreshingly cool, so I can work comfortably inside even in the summer.

  • It cools very well.
Size: 12000-115
Our bedroom tends to get hotter than the rest of the house, and this air conditioner has been a huge help at night. I hope it can withstand the scorching heat of a Phoenix summer, but only time will tell. So far, I’m very satisfied with this product—even if it only lasts five years, it’s still worth the money to me. I hope it lasts a little longer. It runs quite quietly. ... show more
