Quickly shipped, only took a week even crossing the border, to get to me in Vancouver BC. Had a couple of questions that were quickly resolved…..

Thanks for the kind words!
Cool mini split was awesome, bought the universal unit and it was the cheapest when taking into account no tax. The unit got here with in two weeks. They use a third party freight company, but item arrived in good condition. The staff was very responsive and helpful. I will definitely buy from them again and will recommend them.

Very nice experience dealing with this company. Alex was very informative and helped me get back on track with my project. Shipping was fast even though they had some tech issues. Would do business with them again.

After three weeks of asking just one question and even contacting the owner of the business for an answer there is still no answer. The question was that they claim that no special tools are required to install the system. My question was if no special tools are needed then what is the best way to bend the copper tubing to make a 90 degree turn to fit through their elbow fixture of the lineset covering. Bear in mind that if you so much as get a kink in the pipe the warranty is void. My question still goes unanswered but I am led to believe that a real customer service rep is looking into this. This rep also stated that she would look into why I was called at 5:30 in the morning and apologized for that. The rep contacted me 5 days ago and there is no answer in sight to this simple question. Read their on site reviews and you will readily see how very poor that is. At last I got a response but not from Mr Cool but rather another company who sells the lineset cover. After I posted a complaint Alex contacted me and then went through my posts to find my problem. It was Alex who provided the answer and I am thankful for the response telling me that not only can the copper tubing be bent by hand and if it went wrong the warranty would not be voided I was also provided with a you tube video to watch. Great customer service from an individual who went the extra mile. Thank you so much Alex I very much appreciate your work and more importantly your answer

Hello Michael, my name is Alex from cool-minisplits.com and I just saw that you left a 1-star review on our trustpilot page however I think this is a mistake. After checking your order #91316, you only ordered from us a line set cover for $129. I also had a look at your trustpilot profile and noticed in your other review that you purchased your complete DIY system from Ingram's Water & Air which is not our website (cool-minisplits.com) so you probably spoke with their customer service and not ours. I also checked our phone record to see if we had any calls with you and we do not. I'm so sorry you had a bad experience with one of MRCOOL dealers and this doesn't reflect our customer service as you can see all our other positive reviews. To answer your question, the copper tubing can be bent carefully by hand. Refer to this YouTube video https://youtu.be/swNb_OuvYmE or the MRCOOL YouTube channel for installation tips. By the way, breaking a line set will not void the warranty, you can just replace it with a new one. I hope I answered all your concerns, please reach us on our direct line if you have any more, thank you. (302) 385-6142 Alex.
