I went on a no cool call yesterday to find the residential split system a/c was completely out of refrigerant.
After easily finding the leak in the evaporator I informed the customer I would be able to repair the evaporator coil.
Normally i wouldn't braze on an evaporator, but the leak was on the head tube and appeared to be caused by friction from the galvanized cover.
After I made all the repairs I began to put the galvanized doors back on. I noticed the door would spark when I hit the evaporator tubing a certain way.
I turned all power off to the equipment outdoor a/c and all and it still would short out.
I then informed the HO the cause of the leak was an electrical ground.
Told HO to call electrician to have the short found before I complete my repairs.
HO then told me he had wired up some new receptacles and lights.
My bill was right at $500.00 dollars. Electrician charged $225 to locate the short and repair.
HO had a hot touching a metal box searhing for ground in a mobile home.
He could have had the receptacles and lights installed for less than $725.00.....
Don't think you know how get some one who does. If a pro should mess up you can hold him liable.
