The system wasn’t keeping up to the set temperature. I arrived to diagnose the system. I found the refrigerant pressures off. I found the filters dirty. I removed the filters. I recommended replacing them as soon as possible. The evaporator coil is clean. The condenser coil is clean but I gave it a quick rinse. I adjusted the one damper going to the dining room to half open. It was shut off completely. The pressures stabilized at 365/140 in correct range per manufacturer specifications with 10 subcool. The temperature dropped to 71 during the visit which is the customers set point. The 45/5 run capacitor is in correct range per manufacturer specifications. The compressor amps are 6.18 in correct range per manufacturer specifications. The condenser fan amps are .63 in correct range per manufacturer specifications. The system is working properly at this time.
