          We are 75 and 74 years old and we put in the system. Due to the heat index it took a,week to get get everything done. It is so quiet you don't know it's running. Curious to see our power bill.

          Home Depot Mishandled Everything
          All the parts of my original order never arrived, Home Depot said I had to refund and reorder. I did that, then I still did not get all parts of my order. Contacted customer service and opened an investigation, to which was useless. I was never provided any information out of the investigation and I contacted fedex and did it on my own. Turns out the last part of the package was too heavy for ground shipment (175lbs) which Home Depot should know and they didn’t and shipped it incorrectly. I was able to get the product from fedex, and it was damaged because it was not packaged well with no protection by Home Depot. I was able to contact the vendor directly and get some replacement parts but for $4000 I would have expected way better care of the product. The shipping and overall subsequent investigation was a joke and completely useless. I will avoid ordering anything online from Home Depot and will tell everyone I know the same thing. Mr Cool customer service on the other hand has been very helpful and responsive. So far the unit works

            Over all easy install. Printed directions are lacking but plenty of videos available for clarification. Units are so quiet! Overall very satisfied.

            This is wonderful! My only complaint is about the fear instilled in the installation guide about connecting the pipes at the right torque value. I bought a $105 HVAC torque wrench that proved useless. More importantly, if you call the help line, during Mr. Cool's wait time they actually give tips on what must be common problems. They tell you to turn the wrench until all the threads no longer show. Well that should be written in the installation guide because that basically means you tighten them as far as they will physically go. Hope this random tidbit helps you with your install. Buy the thing. It's amazingly easy to put in otherwise!
