Can I Run a MrCool DIY Line Set Down an Interior Wall? - Ask the Expert Episode 233

Today's question comes from Timothy. "Hey Dan, I'm looking to install a MrCool DIY Multi Zone mini split in my house. One unit is going to be placed on the interior wall and I was going to have the MrCool DIY line set run down the interior wall and then under my crawl space to the condenser unit. My house was built around the 1930's, so it's a true 2x4 wall framing. How tight of a bend can the MrCool DIY line set be manipulated to make this work? Or will I have to find an alternative solution?"

Can it be installed that way? Yes, it can be, but it's going to be a little more difficult that a normal DIY installation. If I'm understanding what you're saying, the line set is going to have to go straight down through the interior wall. So, that means you're going to have to bend that line set a full 90 degrees, which could cause problems. You are going to have to be really, really careful to make sure you don't have any kinks or creases in that line set. Ideally that should be done by somebody who has done it before. You may want to ask someone you know who has.

If you do it wrong you could really mess up the MrCool DIY line set.

    Yes you can easily with DIY LINES but be sure to wrap the lines with the cloth tape which helps it slide easier. Just be careful, I used a rope to feed one end while the other person feeds other end
