Hello, I've noticed there's a film of oily stuff on the bottom of the line set valve cover, and a good amount of it under the flare connection. I ran my finger under the connection and the substance is very sticky.
Do I have a leak or did the contractor go crazy with Nylog and squeezed a whole bottle of it?
The system (3-month-old Fujitsu 24K minisplit) is working and keeping my house at 65 (mid-30s outside). But I've noticed the indoor fan is on high all the time blowing lukewarm air. About 2-3 weeks ago we had a discharge temp error and the contractor came out and found two service adapters that were left on the machine during installation and supposedly added more refrigerant.
Thanks in advance!
