MRCOOL DIY 36,000 BTU Ductless Mini Split AC and Heat Pump with Wireless-Enabled Smart Controller

I selected this unit because the warranty is valid for DIY - unlike most competition. Installation was straight forward. If you can tighten a bolt, then you can connect the condenser to the air handler - that simple. Packaging was VERY well done - no chance of shipping damage. Installed just in time to weather a week long heat wave. Unit worked flawlessly. Very happy.

Installed the unit in a basement remodel. The installation was straight forward for a medium skilled individual and the unit looks and fits well into the space. Only recommendation is that I would upsize to the next model as it is having a tough time keeping up in the cold temperatures we are having. I live in Pennsylvania and the temps have been pretty low so believe a bigger unit could provide more heating capability. All other features (cooling, operations) have been very good.

This unit is great in the summer and cools off very well, however in the winter time i have this in a 400 sq ft shop with only 9 ft ceilings well insulated and it takes several hours to take the chill out and my electric bill is is insane. i bought this unit only to take the chill out and did not think it would take the place of a larger gas unit but very disappointed in the heating aspect.

I replaced an old electric furnace in my garage with the 18k unit. The DIY model was as advertised...very easy to install. I finished on a 95* day in July, shut the garage and fired up the unit. Within 2 hours the humidity was gone and the temp was 76*. Unless you have an electrical background like me, you only have to hire an electrician. I now have heat and AC in my 3-car garage running off only 20 amps....compared to the 90amps of the old beast.

After reading other online reviews, and researching the installation process, I purchased a MRCOOL 18 K Mini-split system for my remodeled attic. The installation instructions were through and it took us about 4 hours to complete. The unit now quietly cools and heats the attic comfortably! Saved me lots of money installing it ourselves. No real need for a costly HVAC 'expert'.
