Tech performed PTU. Upon arrival homeowner stated mini split inside pool house was not heating. After further inspection tech found mini split void of refrigerant. Tech spoke with homeowner and would like a field supervisor to get in touch with homeowners to give them the best possible solution versus system replacement or repair. Tech informed homeowner repairing a leak on a 2 ton mini split can get really pricey. Also depending on were the leak is, sometimes it is non repairable. Tech also installed surge protector after homeowners approval. Homeowners are selling home and declined ESA.
