Today's question is from Eric. "Hey Dan, how many line sets fit in a single MrCool Line Guard?" So, he's talking about the MrCool Line Guard, which is a line set cover kit for your ductless mini split. Though they are from MrCool, they could work for any ductless mini split. If you get a Mitsubishi, a Gree, or Daikin, you can get a MrCool Line Guard and it's fine. It's just a plastic cover that goes outside your house. You put it on the outside wall where the line set comes out. The lines go out, you cover them and it looks neat. So how many line sets can go into a MrCool Line Guard? One. Just one. Each MrCool Line Guard line set cover kit is designed to work with one single zone mini split. If you've got a multi zone mini split unit then you will need to get more. You could try to put more than one line set in the MrCool Line Guard, but I don't think it would work very well. It would probably not be very effective. Any more questions? Just ask in the comments below.
