Hi, I have an a/c which I have been using these last two years and lately, after around 2 hours of usage on cool at a temperature of 22 degrees Celsius, large drops of water start dripping from the A/C vents and keep on dripping on and off until I switch it off.
Can someone tell me what the problem is and whether I can solve it myself ? Thanks

Your metal boxes in the wall that the duct is attached to are probably not insulated. If you find this to be the case then there is a simple solution, buy some fibre glass duct wrap from a supply house or hardware store and wrap these fittings. Mike
