For this evaluation the customer stated the unit was only blowing hot air. I started at the condenser, and I could hear the compressor was trying to turn on but wasn't however the fan was running. I tested the capacitor and it was way out of tolerance, so I put a new one on and the condenser fired up. Due to a lower than target superheat with a piston metering device I believe the unit may be overcharged. I talked to the customer about replacement versus a major repair like replacing the metering device however the customer wants to wait.
