Found package unit running ok for age at 24 years old. Found the low voltage control wire for power had no insulation on it for about 8â€. Taped it up so it doesn’t cause a short. Blower wheel is a little dirty but not bad. Capacitor for compressor and outdoor fan at minimum specs. Split Trane unit is running ok. Could not see any cracks on heat exchanger. Recommend exploring replacement options on package at least due to age and R22 refrigerant.
