Completed Full inspection of both upstairs and main level furnaces and air conditioning systems. Found numerous issues including the upstairs level system leaking refrigerant and causing it not to cool, the main level furnace having a cracked heat exchanger and not safe to run, along with other code issues. Ultimately based on price of repairs, I would recommend to replace the upstairs AC unit along with the main level furnace. The ductwork on these systems are not up to current insulation value standards and it would be best to also replace ductwork.
