from 439 reviews
Not a DIY unit, but if you're handy, YouTube will make it happen and you'll love it!

First and foremost, this is not a do-it-yourself unit, unless you have HVAC equipment and watch plenty of YouTube videos. I thought it was the DIY unit when I purchased it so I had to learn how to install it. I am using it in my garage in the Chicago area and this 1.5 ton is a great performer. No need to run consistently but when heating or cooling is required it gets the job done. In the heating mode the outside unit is a little noisy but I hope to eliminate that when I insulate and drywall the garage, but the inside unit is super quiet. The wifi works as advertised and operates from my smart phone from anywhere. The wireless remote does not communicate over or with the wifi and takes a few extra button pushes to get it to respond. I purchased aftermarket air filtering sheets and I was shocked at how fast they got dirty. Worth the few extra pennys in my opinion. Overall, I absolutely love it.

MRCOOL Advantage 5th Gen 12,000 BTU 21.2 SEER2 Ductless Mini Split Air Conditioner and Heat Pump - 115V
My mistake, not the unit

I didn’t read the description closely and didn’t realize this was the non-DIY version with uncharged line sets. That part is on me. Once I understood that the condenser comes pre-charged and the indoor unit is nitrogen sealed, everything made sense. I picked up gauges and a vacuum pump and finished the install without issues. Unit works great.

MRCOOL Advantage 5th Gen 12,000 BTU 21.2 SEER2 Ductless Mini Split Air Conditioner and Heat Pump - 115V
DIY-ish, but not beginner DIY

Not impossible, but not a “Saturday in flip flops” job either. I did most of the install and had a buddy with HVAC tools help finish. Single-zone runs great and is crazy quiet.

Scott Reynolds
MRCOOL DIY® 5th Gen E Star 12,000 BTU Single Zone Mini Split Complete System with 25ft. Line Set 115V, DIY-12-HP-WM-115D25-0
Nice little unit

I intentionally sized up one level and I’m glad I did. The unit doesn’t have to work hard and seems more efficient because of it. Install took longer than expected, mostly due to drilling and routing lines, but performance has been excellent.

MRCOOL DIY 5th Gen E-Star Series 18K BTU, 1.5 Ton, 21.5 SEER2 Ductless Mini-Split Heat Pump System with Ceiling Cassette Air Handler – R-454B
5 zones for my customer

I’m a part-time HVAC tech and builder, and I’ve installed several mini split systems over the years. This 5-zone setup has been a great option for customers who want flexibility without running ductwork. Performance has been consistent and reliability has been solid so far.

Scott W.
MRCOOL DIY 5th Gen Multi-Zone 5-Zone 36,000 BTU 23 SEER2 (6K + 6K + 6K + 6K + 9K) Ductless Mini-Split Air Conditioner and Heat Pump
3 air handlers for our cottage

Installed a 3-zone system to cover bedrooms and a living area. Being able to control each room separately is a game changer. One outdoor unit, three indoor heads, and no more fighting over the thermostat. Very efficient and quieter than expected.

Definitely Not A Robot
MRCOOL DIY 5th Gen Multi-Zone 3-Zone 18,000 BTU 23.9 SEER2 (6K + 6K + 9K) Ductless Mini-Split Air Conditioner and Heat Pump
Awesome a/c

We had an HVAC tech install an 18k unit in our bonus room. It cools that space faster than our central system ever did and runs almost silently. Thick walls, solid build, and it looks clean on the wall. No regrets so far.

Dave R.
MRCOOL® EZPRO® 18k BTU DIY Mini-Split Heat Pump System – 5th Generation (R-454B)
DIY with minor complaints

Cooling performance is excellent and it’s whisper quiet once running. The install wasn’t difficult, but the instructions could be clearer and the WiFi setup took a bit of trial and error. Once it was dialed in, though, it’s been rock solid. Would still buy again.

Do your research on the seller

The mini split itself is great, but the seller makes all the difference. MRCOOL DIY Direct helped me sort out mistakes made by another retailer who didn’t understand the product. Returned everything and reordered correctly. Wish I had done my homework sooner.

Very Happy After A Month of Operation

Put a 24k unit in my insulated garage. It cools it down fast and holds temperature easily, even during heat waves. Almost silent inside, and the outdoor unit isn’t obnoxious either. Wish I had done this years ago.

Not just a website

What sold me was realizing MRCOOL DIY Direct is an actual HVAC company, not just a storefront. They know these systems inside and out. After getting burned by another seller who sent the wrong components, I switched and couldn’t be happier. The support alone is worth it.

Not perfect but they made it right

Had some hiccups with the install and I wasn’t thrilled at first. The system itself works good now, but the biggest thing was the help I got. MRCOOL DIY Direct walked me through what I needed and fixed the mess I made ordering elsewhere. That part alone earned the 4 stars.

Install was rough, support was solid

The install wasnt as easy as I thought and the manual didnt help much. I had a few “what did I get myself into” moments. MRCOOL DIY Direct answered my questions and helped me figure it out. End result is a working system and no regrets.
