Upon arrival Property maintenance show me an air handler in a condenser on the roof that was freezing up. The evap coil is clean. indoor fan motor was running went on the roof check the capacitor and everything is running as it should. Put gauges on the system and the Freon is really low. Priced out to do a lease search and customer said they’re going to have the company that installed it come back out. Property maintenance said he is going to add Freon himself. He’s been doing it for the last month of adding 2 to 3 pounds every two weeks. I gave him a price to add 3 pounds of Freon and do a leak search and customer declined. this is a commercial apartment complex please bill
