Bravo, @Rand!
You saved yourself several hundred dollars by repairing it yourself and as BITOG regular, I am certain that your workmanship exceeded the HVAC technician's quality.
Based on what????
There are many excellent technicians out there... no need to slam a whole trade group because a guy saved some money.
There were a couple in this thread that were offering to let him use their accounts.
What do you do for a living?
