Leaking Minisplit Heads
Hi all, We have a Midea mini split mounted on an indoor wall. Behind this wall is an unconditioned entry hall to a 4 unit building. The suction lines and drain line run inside the wall aprx 15 feet to an exterior wall where the outside unit is. It has been leaking water down the wall cavity/wall behind the indoor unit for months. The drain is completely clear. We have checked it multiple times. We took the plastic cover off, and with a flashlight were able to see condensation (a lot) running down the lines (which appeared to be insulated but maybe just wrapped in black tape). The lines run up from the unit before heading towards the exterior. Behind the wall unit we see there is a large opening in the drywall…presumably made during the installation. We have had this unit looked at by 4 reputable hvac companies who can’t seem to get beyond “a clogged drain line” to trouble shoot the real problem. The freon level is fine. Could the large opening the drywall behind the unit be part of the problem? Should we remove the whole unit from the wall and check all the insulation? Any suggestions? We are at our wits end. Thank you!
