Great video! I had no experience with mini-splits, but just bought a house filled with them. One of our units was not working prior to moving in, and of course it's in the room that's 75% windows and in Texas and in the summer. I watched this video and did a decent amount of research, and decided it was worth it to risk the price of the kit even if it wasn't the solution. When the kit showed up I quickly learned my pipe configuration was different than the video. I sent a couple of pics in an email and Brian responded almost immediately, and within 10 minutes I had cold air blowing! The kit barely costs more than many techs will charge just for diagnostics. I could not be happier that I stumbled across this video. Thanks, Brian!!!

This kit works! I admit I was a bit skeptical whether it would fix the low refrigerant problem in my Mitsubishi mini split. I'm happy to say that I had zero problems using the recharging kit
and my air temperature went from 61 degrees to 49 degrees. Anyone that's even a bit "handy" can use this kit without issues. Thank you Mr. Niskala for this video and your money saving kit!!

Process was very simple and straight forward. Got my unit recharged in less than 10 minutes which was great. I have MR. Cool mini split. Difference was immediately noticeable. Hoping sealant will fix issue. I do recommend to anyone.

Bravo. My 3 ton unit had been running great for about 3 years but has been struggling a lot these last 5-6 months. It was definitely on the low side and your kit and instructions were easy to follow and got the unit working great again. I'm on the hunt for any leaks now.

I just ordered and got one of these for my mr cool universal. I was not getting much heat. This did the trick. Shipping was super fast and sameday!!! Just goto the website in the description. Try this before anything else. If your heat pump is running more, then it should! Thanks Brian!!

This fix was spot on for me. Unit was displaying PC03 error. I had some trouble at first (all user error), emailed and received a text and a phone call. Brian was super helpful and walked me through the process. Thanks Brian!

Super helpful video. I ended up buying the refrigerant from Brian. He always responded to my emails extremely fast. After I had some additional issues unrelated to refrigerant, he was more than happy to talk to me on the phone and offer his professional level advice. Thanks Brian!

This kit was a life saver! Brian was so quick to email back and the video was perfect for a step-by-step guide. I actually used this on my camper’s unit which did have a refill port. Mine did not require the adapter, but I had everything I needed. It was easy to do and I plan to buy another kit to recharge my Mitsubishi split unit! 10/10 recommend. Last week’s camping trip was nice and cool!

I just had a wonderful experience with Brian. He took time out of his day to allow me to ask him some important questions, Thank you Brian, you are awesome!

Just got my recharge kit today. This is going to be my go to video. Thank you very much!

[TerryDavis-qfus]

Worked perfectly, spoke to Brian and he walked me through it. Saved me a lot of money. Thanks

Thank you for this video and for your recharge kit! I just received mine yesterday and it literally only took 5 mins to charge it up. Output temp was 78° and after charging dropped to 55°! Shipping was super fast too.

Worked on my unit a 12K btu single head senville. Not sure where or what leak was, but started to produce heat like it should. Took whole bottle. I checked pressure on unit after charging and it was right where it should be. Will see how long unit continues to run and recomment if need be. Fittings at compressor were all good, no leaks. Did not check flares and connections from the head unit connections with the line set. If it looses charge will take apart cover and insulation and check for leaks. Unit was originally pressure tested and nitrogen purged when installed. Fittings were all good. If it leaks again might be coil in head or compressor unit. Hope sealant did it’s job. Set to 85 F and unit was putting out 109+ degrees, when set to 70F put out around 88 degrees.

Bought this kit and it worked as indicated in the video. Would highly recommend for the Mrcool diy mini split!😊

I just ordered and hope it makes a difference on it. Thank you for your help and support.

Hi Brian, I bought a kit early in 2024, as my 5 year old mr cool 18k wasnt heating or cooling anymore.. The kit worked great. and has been working well. just today the indoor unit was frozen up solid. I let it thaw out, and it is running again. I just used the gauge that came with the kit, and found that my coolant had dropped below the blue zone and into the top of the yellow.

So my question is, can I order just the canister of R410a without the gauge? If yes then how would I do that?
Thanks, Dan

[naturalstatenversion]

Just purchased the recharge kit from your comutrader store. Looking forward to seeing how it does

[Leoleeartvideos]

Brian, thank you for all the helpful advice and this tutorial on how to use your recharge kit! worked great and shipped quickly! I highly recommend this kit👍 Can I use the gauge over again to measure my other minisplits? is it possible to order just the freon and reuse gauge?

[ffake]

Just got my recharge kit from Brian. 100% vouch for this guy! Fast shipping, followed the instructions, my Mr. Cool is Mr. Awesome Cool now! Worked like a charm. Thanks again!!
