MRCOOL DIY 24,000 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.

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'.

This has been a great addition to my garage workshop! I installed it myself which went as advertised and no problems. It worked great for cooling in the Las Vegas summer heat. It has been heating the garage in the colder weather as well. I should say that the garage is insulated and is about 650 sq ft. I have not noted any major change to my electric bill but i only run it when i am working in the area.

install is simple for the most part, found a way to install on interior wall because exterior wall was bad location for outside unit. (housing district maintains air units must be installed in rear of building) would be nice if you could buy extentions for piping to go 50 foot. Unit performs well so far keeps room at 70 day or night and really never hear it running. even outside condenser is very quiet.electric bill has doubled using 2 units but it has saved me 600 dollars in gas usage when calculated out. Did I mention that it's very quiet, had trouble falling asleep first couple nights not hearring furnace kick on and sound like a diesel truck, always afraid pilot may go out and fill home with gas.These units run scary quiet. Hope they can handle constant running though. don't think they've ever turned off. Really can't tell for how quiet they run. Have told and shown several neighbors and they have purchased their own now
