Changed air filter and added plasma pure air cleaner to the furnace. Did Maintenance check on 2013 amana ac unit. The unit looks like it may have been hit with a mower or something at one point. The unit is sitting a little cockeyed and a couple metal fins are bent up on one side, also the liquid line on line set is a little bent up going into the block foundation. Initially had some issues with suction line frosting up. Tried adding a pound of refrigerant but suction pressure did not change. I went in a found about 8 vents closed off in the home. Opened the vents and increased fan speed for cooling to high speed. This helped with the line frosting over but refrigerant pressure still seems off. Removed the pound I put in and we are waiting to see if ac gives customer anymore issues once it gets warmer. Left a quote to removed refrigerant and pull vacuum but that is not a guaranteed fix. Also leaving quote to replace Evap coil and refrigerant line set.
