Unit off upon arrival. Turned it on to test operation. Found system low again on refrigerant. Added leak sealant again with R22 refrigerant. Balanced charge to proper superheat. Added locking refrigerant caps for mn code. System is cooling at this time, but system definitely has leak considering unit has leaked refrigerant now again, this is a bandaid fix once again, it may work for a few weeks, possibly a month, it’s hard to say. Replacement will be the next step due to age and condition. Will have Jacob follow up next week to chat about replacement options again.
