Ac was off upon arrival. After turning the ac on I then proceeded with my diagnostics and found that the indoor units filter was completely plugged up. This was preventing any air from flowing throughout the system. I then removed the filter and installed a new one, this allowed the ductwork to move air a lot better. Overall the ac does appear to be low on refrigerant and will not cool the house down properly. With the age of the system and the cost of repairs needed I highly rec omens looking into replacing the entire system. Home advisor visit scheduled for 6-10-2022 at 1 with our home advisor Chris A.
