I went to a call Friday afternoon, the work order said customer needs a charge of freon. Got there to find that the homeowner had installed a dual zone mini-split. Said that he just needed to charge it up. I said they usually have the charge in the condenser, and that it just needs to be released. He said that he already did that, but the system isn't cooling. Soooo, we go into the house. What he had done was, he only ran one line-set to one of the evaporators, teed off that line to the other evaporator. Went out to check the condenser, and there was the other zone for the other line-set untouched. I just felt so sorry for this guy. He must have spent the whole week running the one line-set, knocking holes in his walls, and feeding the teed-off line-set through the 14" attic to the other evaporator. So now he's out all the time and effort and money to try to save a few bucks. Now it's going to cost him more money to have somebody come and clean up this mess, than it would have cost to just have a professional install it from the beginning.
The funny thing is that he pressure tested the lines before he pulled a vacuum. (Vacuum pump borrowed from a friend)
