Upon arrival, I found the customers straight cool, condenser and furnace that supplies the downstairs not cooling properly due to a low refrigerant charge, causing the case coil to freeze over. The system is a 2012 with R 22. Refrigerant. I was able to find a leaking condenser coil and filter dryer. I sent a repair estimate via email, but I highly recommend saving that money and putting it towards a new system which wouldn’t be much more than the repair. The customer agreed I will get a proposal sent with options on a new system install as well. I left the system as it was when I arrived. .
