Complete 1 system a/c repair and preventative maintenance check. Cleaned outdoor coil and checked all components. Systems filter needs to be changed but I do not have one in stock. Removed filter to check pressures. The system looks to be a little low on R22 and I also had to manually start an outdoor fan motor. System 15 year old and recommend replacement. Dennis wants to try to get some money from home warranty company and then quotes on replacing the system.
