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.

These guys are the best,

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.

it works perfectly

Was a little difficult to install, online tutorial was helpful.

Excellent customer service, good pricing, extremely fast shipping, and the product is easier than expected to install and use. One of the few all round 5 star experiences I’ve ever had

Great five stars

It works. Try not to drop them.

This is the first Mr Cool that I have purchased and I am very pleased.

It will probably go in next year (it is a summer place about to be closed up). However, my neighbor just put in his 2nd and he has very positive things to say.

We needed a part to get a customer back cooling and even though we didn’t purchase or install the unit, they were quick to help.

The kit would have been great if I had of known that the shader was the leak in my system. Once I emptied the contents of the kit into the system I tried to remove the bottle and it kept leaking at the fill valve and I lost a lot of it before I could get the cap back on it so I’m just going to get an hvac mechanic to tighten the valve and recharge the system
