MRCOOL 50ft Line Set Coupler Kit for DIY Single Zone and Multizone 24K, 36K & 48K Air Handlers - 3/8" x 5/8"

The line set and coupler seem ok but after installation I find my DIY Mr Cool is low on refrigerant and it will cost me to have it charged. Mr Cool says sometimes these line sets are a few ounces low and have to be topped up. Mr Cool does not want to take any responsibility for this even though they sold a DIY unit. I would not recommend Mr Cool for this reason.

Worked as Advertised

I have installed 8 Mr Cool diys and they are all still running without issue.
