Came out to install a new thermostat back plate and perform an AC check. I removed the original stat plate and placed, leveled, and secured the larger one in its place. With the AC check, I detected no leaks at this indoor coil. Electrical components tested okay. The capacitor is starting to weaken. The fan bearings are good yet. However, I did have to remove a rodent nest. A full cleaning is recommended due to the gap from previous maintenance and condition of the outdoor coil. AC clean and tune
