Well I have been a contractor since 1985.Some light hvac in my you get years but not my specialty.I know how to use my tools as only basic tools were required.
The wall installation is simply mounting the bracket and drilling the hole. inside unit hung right on the wall perfectly 1st time.
As for my installation outside I bought a wall bracket but due to the stud issues I had to build a full stand.As far as total install outside all electrical and line set (copper piping) went together perfectly and easy.
It took me longer to run my new electrical line as I needed to box etc than hooking up the entire unit.
I even got a permit .Few contactor friends even passed by and were impressed with my workmanship.I highly recommend the MRCOOL brand. Even the packaging was so impressive to me how well and protected the boxes and padding were.
And mostly the online tech support from CHILL was even there late at night when I first inquired about a unit and explained everything to me with few choices and footage vr unit size etc that I was sold and so impressed with my Chill Technician/ sales rep.Tyler that I was sold.
I can honestly say ,Its one of the best things that I added onto my home especially for my back addition.And now The back has its on heat/cool and I closed off the vents from my full house heater which will even preserve the life of that a bit. Total Rating 100% satisfied and I truly believe anyone can install these and even hook up the electrical wires and wet box and the line set without any knowledge. It’s that easy.Thanks CHILL and Tyler for the fantastic service and on time Fast delivery.
