Sounds like the weak link in your project was the pros in this case. That is a shame. Just make sure and vote with your voice. If you get an opportunity to advise someone about the service and quality that you did not receive, let them know.

In defense of the sweating, that has been one of my biggest issues with the ductless heat pumps. The linesets sweat. But that is no excuse for the pictures you sent. I have a cat that could have done a better job than that.

That sounds like a shameless plug for your business

Yes. Looking back, I do regret not doing it myself. I could have purchased all of the equipment for around 5K. Another 5-6 hundred for a gauge set, vacuum pump, and flaring tool and I could have saved myself a few thousand. Plus, I know it would have looked a lot neater than this. The lineset that I'm realy having trouble with runs up when it exits the house and goes up through the sofitt into the attic. All of the condensation is dripping down these lines and traveling into the wall. However, if they would have made the insulation connectinos airtight like they should be, the problem could have been mostly avoided.

Part three:
Update. The company sent out another crew. They pumped down the system and removed all of the inside units. They installed wall sleeves in the wall penetrations. They wrapped the linesets and drain line in cork tape from the inside unit to the K-Flex insulation. They cut out the tape joints and used contact cement to connect the pieces of insulation together outside. And, they repositioned the wall plates correctly to take the stress of the condensate lines. They seem to drain a lot better now and I haven't seen any problems with the lines sweating. This seems to be the only big mistake this crew performed. That's what happens when you don't properly prepare a plumbing joint.
