How do I verify the age and efficiency rating of an AC system?
The AC unit itself usually has a manufacturer label or data plate on the exterior condenser that shows the brand, model number, and date of manufacture. You can look up the serial number online using manufacturer databases to confirm the age. The SEER rating, which measures efficiency, is also often listed on the data plate or available through the model number lookup. You can review the seller property disclosure statement for information the seller provides about the system, and check for any service records or maintenance receipts. The specifics depend on your situation and a licensed home inspector should confirm the condition, age, and efficiency of the system during your inspection period, and Jon can connect you with one.
