Reviews for MRCOOL DIY 4th Gen 36,000 BTU 16 SEER Ductless Mini Split AC and Heat Pump with Wireless-Enabled Smart Controller-R410A

My first experience with DIY AC units. My ONLY problem with the system (in my work shop) Is the material is made from. Attracts dust rapidly. If there is a solution to this would love to know about it. You can't keep it clean. Dr. Julian Fields, MD.

I bought this unit for a rental. I could have bought an A/C upgrade for the forced air heating unit in the house, but this was my third mini split install and it was only a third the cost. The renters are very happy with it for a 1200 sq. Ft. House it keeps it cool when we get over 100° in the summer. They love the wifi connection and are able to warm the house or cool it before they get home. Good price and easy installation.

So far the unit is working great!

Easy to navigate web page and pick unit.

Easy to order.

Very quick shipping / receiving.

Easy to install.


Don’t think there is much to change to make it better.

The unit arrived in good shape although the pallet was damaged. It's been installed for about two weeks. Unfortunately the temperatures took a bit of a nose dive and we have only used the AC once. I was able to program the thermostat, but had some trouble hooking the unit to the wifi. I will attempt again next week. Overall I'm very happy. Everything I needed was sent. Because the walls are thick I had to cut a piece of 3" pvc pipe instead of using the supplied pipe

I was overall very happy with my order, both of the Mr.Cool units were relatively easy to install and both are running fine. I was also very happy with how well you guys packaged the pallet that I received, you wrapped the pallet and put big thick cardboard around the whole thing which did a great job of protecting my expensive purchase while in transit. In fact the freight driver even commented on how impressed he was with the packing, remarking that most places wouldn't exercise that level of care.



I would rate my transaction a 10/10

the install went fine and unit is up and working in the middle of the hottest summer we’ve had in Oklahoma for years…thanks again

Order was great

First: HVACDirect.com website was easy to navigate to all the items I was in need of. Second: Shipping was fast and secure.
I have already installed the 3 ton MrCool 36K DIY, and the instructions were easy to follow. I do recommend getting the electrical installation kit for those that might not do electrical work on a regular basis. After installation the MrCool HVAC system looks professional, works great, and I know it will last for years. I plan to install more of these for the company I work for because of the quality, and ease of installation for the DIY consumer such as I am.
