    Truly DIY & Amazing Company

    The only thing that we paid extra for was for the wiring to be altered. We have a zone in each room and all in all everything was set up within a days time (9 hours) for 4 zones to be installed, no issues everything works amazing and is keeping our house extra cool this summer. Will definitely be recommending this product to everyone along with this company. We did order to short of a precharged line and I quickly went online and ordered the new one, sending the short one back. Within an hour I was messaged and told that the line I ordered wasn’t the correct one and was asked if I wanted to modify the new order to fit the correct unit I got, I was impressed with how fast and how efficient they are with making sure their customers are happy and not having to go through yet another return process. Such an amazing company!

    Mr cool DIY

    These work great!! We built out small stub walls to hang them on and ran the connections through the basement because the original walls of this house are solid rock and plaster. They keep everything surprisingly warm/cool!! Live them!

    Mr. cool package, simply allows the homeowner to do all of the work!

    I purchased the Mr. cool wall mount two air handlers and of course, my outside unit. One year later this product is simply amazing. Still working as it should and the heat pumps are just magic! I would highly recommend Mr and to top it off. Customer service is simply top shelf.
