Ac check. Used refrigerant sniffer to check indoor coil for any issues. Small indications of possible leak. Cycled system. Checked pressures and temps. System was slightly over charged. Used megometer on compressor, tested a bit low, but ok. Capacitor is lower than tolerances a low to pass. Split was 19. Average life of this system is 14 years. This system is 20+ years old and in poor condition. Future failure is expected. Second opinion recommended. No charge for this call. Job complete.
