[@user-ok4pw9ow6z]

Very helpful!!! I'm about to buy a Mr Cool

[@LindaEldredge]

It's great to know how to do this. I may use this in my next AirBnB unit. Thanks!

[@sunhippie]

Thank you for taking the time to make this video. We're installing a 5 zone in my house and this will help us a lot!

[@TheRenoBros]

So glad you've found it to be helpful! If you have any questions about anything we didn't show in this video, feel free to reach out. We did a 4-zone and a 3-zone in this property!

Hey I appreciate the pace of your videos, I think it provides a more realistic depiction of the steps involved and how long things can take than most other channels- thanks!

[@TheRenoBros]

Thanks for that feedback! I’m glad to hear the pacing was helpful! We’re aiming to provide better value and expectations in this space and it’s great to know that that is showing through.

Hi Watched your video in full few notes I wanted to mention you didn’t do a pressure test or vacuum machine nor you’ve used the thread sealer in case of any leak on high pressure tube pipes I’m amazed according to what you’ve mentioned the pressure nut is running well after 12 months since been installed

[@TheRenoBros]

Mr Cool DIY are precharged with refrigerant and have a proprietary connector. No vacuuming, pressure testing, nor thread sealer needed.

Awesome thanks this is going to help my install. The door casing on your closet made me have a seizure

[@TheRenoBros]

You’re welcome! 😂😂 You’re so right! I sure would love to meet the guy that did that and find out what he was thinking lol

Does the black electrical wire that leaves the outdoor unit and goes through the lineset cover to the inside unit need to have some sort of flexible conduit on it in the area between the outdoor unit and the lineset cover? At 23:28 it is shown exiting the outdoor unit with no conduit and not grommet of any kind to protect it from the metal cover of the outdoor unit. I'm getting ready to install one of these units and I hadn't thought of adding the conduit until I saw someone mention it elsewhere. But it seems like a good idea.

[@TheRenoBros]

Yes! I talk about this in my most recent KZbin video about the Mr Cool. Check it out if you haven’t already. GOOD EYE!

[@TheRenoBros]

@@shanefrank3281 Yes! Maybe you’ve already seen and commented on that one too. I talked about flexible conduit (liquid tight tubing) in that video after someone recommended I use it to protect the control wire from the elements.

[@shanefrank3281]

@@TheRenoBros Ok. Yes I have seen that one, but I must have missed that part when I first watched it. I will watch again. Thanks!

@@shanefrank3281 Gotcha! Yeah let me know what you think when you find it!

Do you have an issue with the angle of the louver (the piece that swings up and down to let air flow) when using Cool mode vs Heat mode? On my MRCOOL, when I'm in Cool mode, the louver stops about half-way down and swings back up. In heat mode, the louver swings all the way down, parallel to the wall, and swings back up, only stopping half-way, and swinging back down again. Do you have this issue or is this expected functionality?

[@TheRenoBros]

Good question! I have had some issues with that as well. I plan to do a review of the system and mention some of the drawbacks I've noticed that could use improvement, and that is one. As far as troubleshooting, Mr Cool has some resources that have helped me (such as their forums or FAQ), and Ingram's Water and Air has also been super helpful answering questions.

Not sure that these are the Panasonic internals, if so you may need a firmware upgrade as mine was doing some weird things. Ended up with a firmware upgrade... All good now.

You sure that lineset didn’t get Kinked? Pushing it down that hard? That would restrict the refrigeration flow. I would recommend a copper tube bender next time to avoid that. Tightening the fittings on the lineset needs to be done with a torque wrench per specifications of the manufacture in the manual. And also coiling up the Line set vertical can cause oil traps. They need to be coiled horizontally. You won’t get oil back to the compressor and it will damage the compressor in the outdoor unit. I’m an HVAC instructor just throwing out helpful advice for future projects.

[@TheRenoBros]

Thanks for the advice! Could you elaborate on the oil item you mentioned about the coiled lineset? I didn’t quite follow. Also, the bending method I used is recommended by the manufacturer since the line sets are pre-packed in their protective weatherproof sleeve. You wouldn’t be able to use a tube bender for these properly. As for the torque wrench, that may be a good extra step for peace of mind, but I got a good seal on it with the manufacturer instructions alone, which recommends a specific process as well as a check.

[@olivert2549]

I definitely agree, and you can always cut that uv wrap/ insulation and just zip tie it back together to check for kinks. Better to be safe than sorry

[@olivert2549]

as an hvac tech this was hard to watch

[@TheRenoBros]

I'd absolutely love to learn your feedback on what should have been done differently! Thanks for the comment!

[@SoCalBruce]

Why was this hard to watch? Some constructive criticism would be helpful. Or are you just afraid of losing business to do it yourselfers?
