Arrived and the customer stated earlier the system was frozen. It has been off and thawed out. She washed the filters and tried it again but the same thing happened. The system has a history of a refrigerant leak. Gave the customer options to search for the leak and either replace the coil that is leaking or repair it. Also gave pricing g for a replacement due to the age of the system being 10 years old. The customer will look over the estimates and will get back to us when she decides what to do.
