I am a highly skilled and experienced home service professional. I recently completed a routine maintenance job on an air-conditioning system. During the inspection, I verified that the airflow was adequate and that the amps were within the acceptable range. I also checked the outside amps and the capacitor and found them to be functioning properly. I then moved on to the refrigerant side of things and discovered that both units were low on refrigerant. I filled them with approximately half a pound of refrigerant and inserted a dye check to monitor the system's performance over the next two weeks. If the dye is still present in the system after two weeks, it indicates a leak that needs to be addressed.
