Mrcool Avis 

The product failed. The warranty failed worse.

A licensed HVAC technician diagnosed a refrigerant leak inside the evaporator coil, a factory-manufactured component. MRCOOL never disputed the diagnosis. Their response was simply to deny coverage because the unit was self-installed.

If a manufacturer won't stand behind a defective component and won't explain how an internal coil leak is related to installation, their warranty has very little value.

Would not buy again.

I bought two MRCOOL Universal systems, a 2.5-ton and a 3-ton. MRCOOL does not perform as claimed for triple-digit temperatures. Their customer service is lousy; they told me a dozen times someone would contact me, but no one ever did. The equipment arrived grouped perfectly; however, the installers mismatched them during installation, which caused the units to lose refrigerant during the correction. The installers left exposed wiring, incorrect electrical connections, multiple safety concerns, and got the warranty voided by installing the equipment backward. Don't be a fool by buying MRCOOL, which should be renamed MRJUNK.

Mini Split AC systems are great ! You can add Head and A/C to an older home that has no ductwork, etc.

Mr Cool however. The system will last exactly 5 years and then take a dirt nap and you'll have to buy a whole new system.

AVOID AVOID AVOID Mr Cool !

After a month and a half with no AC in Florida, no ETA on the warrantied part for my failed 3 ton unit can be provided, still, due to "unprecedented demand". They are not capable of honoring their warranties, or even just keeping parts in stock so their units can be serviced and repaired, even if the unit is new. STAY AWAY if you actually need air conditioning.

Josh F the Technical Specialist helped me out a ton over the phone and over email with a lot of questions and doubts I had about my installations. Very polite and efficient communication as well.

Horible experaince. Very bad support. They do not want to warrenty there product. The system arrived broken and the support doesn't want to call you not do they warrenty threre product. They want to avoid the warrenty.

I purchased the unit with the expectation that the product would be backed by a reliable warranty. Unfortunately, my experience has been the complete opposite.

After 4 years the unit stopped functioning because of PC03 error which indicated that there was a refrigerant leak.

I reached out to MrCool support, and the process was incredibly frustrating. I was forced to spend money and time on purchasing tools and gadgets to run a series of tests just to be asked to conduct additional tests as if they didn’t want to fulfill the warranty. Despite following their requirements, I was told that they would cover the unit if only I paid $520 in shipping costs which was later reduced to $410.

I bought this unit specifically for the ease of a DIY install, but the lack of actual warranty support makes this an extremely risky investment. I strongly advise anyone considering this product to look elsewhere. The cost savings of the unit are completely wiped out when you are left to deal with a broken product and no support from the manufacturer. I will not be buying from this brand again.

If they’re going to charge for shipping then they should have an option for local pick up.

I love mini split systems! I love also the fact that they are very easy to install yourself. The only problem is that it's illegal in Florida. Not only illegal but very complicated to get a permit too. So your advertising of mini split systems as DIY is misleading at best.
I am in the middle of huge problem with my mini split system installed 3 years ago. I have to get the permit for it and the city wants a plumber, electrician and mechanical engineer to pull the permits. Please, send me all relevant information about your mini splits 9000-12000 BTU and maybe some ideas how to handle this problem.

I was frankly surprised that MrCool has a warranty this good on their products. My 6 year old minisplit wasn't cooling like it used to and I contacted their support. In a few days, they determined it would be better to replace my condenser unit. They sent me a 4th generation condenser with a higher energy efficiency than the original. It works well.
The support staff seemed genuinely concerned about my unit's functionality and went to great lengths to ensure that my system was working properly. That meant shipping an expensive condenser unit to me.
Granted, did have to pay the shipping and at today's ridiculous fuel rates and with sales tax, that was nearly $400, but that solved the problem.
The only minor nitpick is the new unit was physically different in a few places, so the mounting feet didn't line up with the studs in the concrete pad, and the refrigerant lines were moved back toward the wall, making it much tighter fit causing the lines to be pressed up against the wall. Also the high and low pressure lines were reversed and it took a while to figure that out, but once we did, we were able to finish the installation and get it working.

They are awful. Customer service doesn’t even know or have any knowledge of the products. They send you YouTube links to try to fix issues. It’s the biggest waste of money I’ve ever invested in. Not to mention the DIY isn’t DIY. It’s a scam.

I replaced a failed geothermal HVAC system with a leaking ground loop with a new energy efficient 19 SEER HVAC system. I will be 69 years old in a few months but with the technical assistance of a MrCool service tech (Carnie) , a little hard work and determination the unit is 100% installed and performing great. I saved thousands by purchasing on-line and installing myself! Great customer service!

I’m very satisfied! Their customer service was a huge help; they have excellent service. If it hadn't been for them, I wouldn't have been able to do it. Thank you so much!

Mr Cool phone tech support is top quality, very knowledgeable and helpful. I called tech support because I had an installation question. The first time I called, the wait time was too long for me so I hung up and called the next day and was speaking with a tech within a minute.

New build home, Mr. Cool was professionally installed. Not even the inspector could get it to work. Absolute trash. Don’t do it. Spend your money & buy something that actually works. I’m out of money, so window units for me. Garbage.

Spend the money and buy a better setup. We were out a lot of money with MrCool after two years. Small house, split units stopped working. Very hard to find handymen or HVAC companies that will touch MrCoo because they are DIY and don’t offer B2B support. The warranty means nothing. They weren’t helpful at with support via email or calls for three months in solving anything. They dragged it until we gave up. I would really avoid the headache.

Excellent service support

Tried to call put me on hold.sent my info through email.will.not cool ac guy ran dector on inside coils found leak.just tried to find out if had warranty 2yrs 3 months old.will not by no more mrcool units for me.

We purchased two new AC units for our home July 2023, and we are having probl3ms with one of thwm not cooling for the second time in less than a year. They charge US to ship the warranty parts. We were promised a 30% savings in our electric bill and it actually went up. WOULD NOT RECOMMEND.

Madeline in the Orders/Customer Service department is a joy to work with. She replied promptly (within 30 min.) and sent me the shipping information without my having to ask. Thank you Madeline, for making this first experience with Mr. Cool a fantastic experience!

I own two of these units and friends/family own several as well, due to me recommending them. I recently had a warranty claim. Although the situation that led up to me needing to contact MrCool was frustrating, they took care of my problems and are replacing a damaged unit that was sent out. I have had issues before but MrCool has always been responsive and helpful, standing behind their products.

I tell my friends and family about these mini splits and many comment that they can find a cheaper one on the internet. Yes, MrCool costs more but you get actual support and US based English speaking support representatives and they stand behind their product. I suggest this company to others needing mini splits and other HVAC equipment.
