NWA Auto Repair

I have studied air conditioning extensively, along with training, and updated my tools over the years to better assist customers. Diagnosing A/C issues is my top priority. This customer had their vehicle 'repaired' elsewhere without resolution. Upon reviewing the vehicle, I saw that several new components, such as the compressor, expansion valve, and receiver dryer, had been installed. Due to low refrigerant levels, I pressure-tested the system with nitrogen and identified a leak at the expansion valve. After getting the go-ahead for repairs, I re-tested the system and found it still leaking (not from the expansion valve repair). It turned out the receiver dryer was improperly mounted and sealed with bent lines. Am I the cheapest? Probably not, but I'm not the most expensive either; however, it would have been cheaper if I had repaired it originally.
