I was called to a home to repair a broken air conditioner. Upon arrival, I found that the breaker in the disconnect was bad and had to be bypassed to get the cooling system working. I also noticed that the previous company had added 3 lbs of 410a refrigerant to the system, which was not the correct amount. I performed a pressure test and found that the pressures were good, so I proceeded to replace the bad breaker and add the correct amount of refrigerant. I also provided a quote for a new 4-ton system to the homeowner.
