Pressure switch was stuck open due to water getting inside. Cleaned out switch. System heating properly.
Complete 1 system a/c repair and preventative maintenance check. Found duct had come off plenum. Reattached duct. Ducts are old and drenched. Need to be replaced and need to add a UV air purifier to the system.
Broken a/c repair call. Checked and found the system frozen due to low charge and leaking. The customer had to add several charges last year. Due to the system's age, poor conditions, and leaking charge I recommend the customer upgrades the system and does not repair. Customer need estimates. The office will schedule asap.
