These guys work on commission and they will rip you off.
Charged me a $850 to install an $85 condenser fan motor.
A guy came to my house last summer when I was without AC and it was hot. He quoted me a price of 850 dollars so I bit the bullet and did it.
It took him less than an hour and all he did was remove 4 screws and plugin 4 wires. He left the new motor box there on my property I googled it and found out the motor only cost $85.
