I have had this installed for about 6 months over the winter in New England. I am very satisfied with its ability to Heat with low outside temps down to 5 degree F. It is heating a 18x20 2 story shop 65 degrees without issues. Love it..

We bought in in july 2018 for our cabin and we have used both the air and the heat. Other then the unit runs all the time i would recommend to any one looking for a heat. An air soure.

i bought this in august 2017.took my son and I only a couple of hours to install,after we ran the electric for it. that took a couple hours also.simple to install,worked just like instructions said.

Works great, just a bit undersized for the AC, but heat works to heat complete room.. Easily installed, just hard to seat with cable and lines out the left side. Should have went one size larger than calculations.

I have lots of south facing windows which lets in a ton of sunlight but Mr. Cool did a great job keeping my house cool this pass summer. The installation took a while and quite a bit of planning so give yourself plenty of time to organize.

Got this for my 2 car and 3 car garage combo shop. It is quiet and maintains temp winter or summer. This is the best thing I have ever done. Wish I had done it years ago!

Installed in a 24 by 54 mobile home. Heating and cooling the whole house. Low energy bills. I love this unit and will be installing another one in my summer cottage up north.

This unit was really simple to install. It does a great job of holding temp, hot or cold. And the best thing, it is so quiet! Both units, inside and out are whisper quiet, I love it. So far, very happy! As far as longevity, we will wait and see.....

What is in the beginning of Summer of 2018. Worked awesome throughout the summer to keep the room cool. Now we're into winter of 2019 and it keeps that room nice and warm. It was so easy to install I can believe anyone can do it.

Very simple and strait forward. I am glad they had 25 feet of hose because I needed 24.5 from second story
