Over time, crankcase heater and high-voltage wires can rub against the copper. These can cause all sorts of problems, including the nightmare scenario of an electric short blowing out the copper and leading to refrigerant loss.
On a normal maintenance call, we should check the wire location and look for the rubout potential. If there is rubout potential, we can insulate the copper line to prevent damage from wire rubouts. Of course, that doesn’t address wire rubouts that have already caused damage, but line insulation is a great preventative measure.

I have been doing this and teaching this to our techs for the past 25 years. We also make sure that none of the factory tubing in the unit can vibrate against the frame of the unit or even another tube in the unit. We call that “housekeeping”. It keeps our clients happy and reduces our callbacks dramatically.
