Leaky Minisplit Heads
Has anyone had any quality issues with Fujitsu units? Trying to determine if this is a known issue, just really bad luck, or something else going on specific to my situation.
I have three Halcyon units that are only 4 or 5 years old. For a couple of years, my upstairs unit (a slim duct) has developed a very slow refrigerant leak. A friend of mine moonlights with HVAC and he would come out, check for leaks, would not be able to find anything, pump me up with refrigerant again and things would be fine for 6 months or so, when it would be out of refrigerant again. This past winter, one of my downstairs ductless units started doing the same thing, but this leak was quicker to drain the refrigerant. Finally pumped the lines up with nitrogena and found that on both units there were leaks in the indoor coils. For the ductless unit, there was a big hole in one of the copper coils (where it loops out and then back in). For the slim duct, all up and down both sides, where the copper loops are, there were leaks everywhere on both sides.
What could be going on here?
