Came out to call. Customer stated that the system wasn’t cooling properly and was constantly running. I checked system over and found the unit low on refrigerant. System is over ten years old and uses R-22. Outdoor system is in rough shape and has had several repairs. I went over repair vs replace options with customer and recommended replacement of the unit, due to age and condition of the unit. Also made her aware that the R-22 refrigerant is no longer being produced and would benefit from replacement than repair. Customer wanted to get system up and running today and wanted a quote for replacement. I added 3.7lbs of R22 to get system cooling properly. Customer is aware that the system has a leak and that this is a temporary fix. No guarantees how long refrigerant will last.
