Repair of 2 parts for my air conditioning took 3 service calls and questionable charges. The first service call, a capacitor was replaced but the cooling was not fixed. Two days later on the second service call, the repairman said that refrigerant pressure was low, but he did not have a replacement for the leaking drier filter, and an additional $180 was billed for 2 hours labor. Three days later when the drier filter was installed, the work was completed within 1 hour and 20 minutes however the bill was for an additional 4 hours and 15 minutes. The repairman said it was for his time to get the drier part. I questioned charging multiple hours at $90.00/hour to deliver the small part. The repairman replied that this was to be fair to his other customers who he also charged similarly. I also questioned the third service billing of $138.44 for the same capacitor that he had all ready been paid $27.82 for 5 days earlier. The repairman said the second charge for the capacitor was an error
