The A/C just started reducing and ultimately started blowing hot. At the repair shop, something was identified on top of the dryer as leaking and had let out all the gas. After this there was a little improvement but again within days it started blowing hot again. Another part like a block of metal with a whole was identified as the culprit I don't know what the name is. After that it improved a little but not like the old way it used to work.
