      Q:Aside from the length of lines separate from the unit (16', 25', etc), how long is the section of line that comes out the back of the head unit? I'm guessing it's around 18 inches, but would like to know for sure.

        Product worked well and was easy to install. Very efficient units. Most importantly the DIY installation saved me thousands on HVAC quotes. This unit heats and cools a 10,000 sq ft climate controlled self storage building.

        Installation was straight forward
        My HVAC friends gave me positive opinions of MRCOOL products. Ordering the MRCOOL DIY from Home Depot was easy. Installation was exactly like in the manual and many online videos. The line set quick connects were fabulous to work with. The system started up perfectly with no drama. I see no difference in components used from any of the other brands, except for MRCOOL's pre-charged line sets and proprietary coupling. Customer Service has been quick to respond to my questions. Way to go MRCOOL!

          Easier to install than instructions make it. You can do the electrical work just as easy. Black and red wires to 1 and 2; and ground to ground. Only need 4 screws to mount bracket; ignore the 50 other holes in it. When leveling, have it slightly lower where the drain tube is. The pipe cover heading out of house should have flat edge at bottom inside house or you will see the ring . Torgue wrench and no taping; just tighten with common sense; never seen a leak in 3 installs

            What MrCool DIY mini-split. I would love to give you a review but I NEVER RECIEVED IT!!! Ordered September 25 with a delivery date of September 26 and here it is October 31 and I still have not received the order even when the Home Depot's web site said it was in stock. Reordered on October 2 with a delivery date of October 4 and here it is October 31 and still have not received the order. Home Depot and MrCool have no tracking capability. I waited around several days to sign for the package and countless hours on the phone to get the same response, "sorry sir but it's on the way" It never showed up, my project is now delayed 6 weeks, thanks a lot Home Depot and MrCool you guys really know how to treat your customers.

            This is because the unit was damaged in delivery. I have been trying to resolve sine July 15th. No success.
            Response from MR COOL TeamOct 30, 2023
            We do apologize for the inconvenience. Unfortunately, Home Depot does pay for their own shipping and will have to do the reorder. If you have any issues, please reach out to me directly at csmanager@mrcool.com. mrcool
