Works like the videos

Watching the videos on installation were very helpful and things went relatively easy. Given the season I haven’t tried the AC yet, but sure is nice to have heat just in time for the cold.

ORDERING PARTS

when ordering parts be sure to look for and only call or request parts from the real MR. COOL DIY DIRECT . There are a lot of fakes selling parts that may not be what you really need. Great folks to deal with .Bill Watson : Florida

Interior wall installation complicated but worked.

Running line sets and drain tubes in an interior wall is harder than just going outside directly and I recommend doing it with unfinished walls on the back as I had to cut out sheetrock, and then you need 6 inch studs to cut out a path for the lines, power, and drain tube which needs to run downhill until you reach the exterior wall. Given that, it went well and I was able to install 2 heads and wire everything up and get it working in a couple days. The one issue I had was connecting the power as the terminals are very small and if you run a 8 gauge wire it will never fit, and even 10 gauge is near impossible. That should be re-engineered to make for easier connections. The terminals are fine for the head wires, but I don’t know why they were covered with a soft plastic cover which i had to cut off to connect. Other than that, it saved me a lot of money and they are working well. I will connect my third head unit later in a work room that I’m not using much and is passively heated. I gave a 5 star but because of the issues above I would have preferred 4.5 stars. Dealing with MRCOOL DIY Direct was easy and they were helpful.

Distraught

For some reason I'm unable to receive my 50 foot precharged lineset that I paid for over 2 weeks ago, so my order hasn't been filled yet and I'm unable to give a feedback on the product.
