Arrived onsite to customers request of having their ductless minisplit system serviced, customer approved pricing, cleaned outdoor and indoor coils using coil cleaner, cleaned filters, tested condensate drain, found no leaks or issues on condensate piping, tested system, found no issues, with operation. Customer had brought up to me that they occasionally have issues with water leaking from behind the indoor unit unable to recreate any water dripping or leaking. found roughly 8” of uninsulated line set this can cause the piping to condense and drip. Attempted to insulate line using cork tape, access is very tight. Cannot warranty repair made today because of this. Additional charges may be required if problem persists. Thank you for choosing CPI Plumbing and Heating Inc.
