My sister is a thousand miles away and I can't go look at her problem.
She had her evaporator (apparently an A coil in the furnace?) replaced with the home warranty, of course there were all sorts of extra non covered charges, but it stopped cooling.
So then they told her the condenser needed to be changed out too, another visit charge plus another set of non covered charges.
Now, in the list of extra charges here, they have to send an electrician to change out the 30 Amp breaker for a 25, because if the condenser pulls more than 25 amps it will burn out and be destroyed.
Say what? Really? Plus they're claiming they need to pull a separate permit for the electrical work which will cost her an extra couple hundred bucks.
My BS detector is going off here. I work in an engineering department. But my section doesn't do residential anymore and I don't know enough.
