Today we visited because the air conditioning is not working. We learned the compressor is the issue. The unit uses R-22 refrigerant, which is now phased out, and the inside unit has a severe mold/mildew issue. The ductwork has mold/mildew growth and seems to be original to the home. Also, there is a vent completely void of ductwork that is open to the attic. Since the system requires thousands of dollars in repairs and uses R-22 Freon, the system will need to be replaced. **This is a rental property owned by Edward and Kimberly Zerka, we will need homeowner authorization before a replacement can be made.
