Arrived to troubleshoot a Mr cool mini split with an error code for refrigerant leak detected. We looked inside and out for the leak but was unable to find it, client approved us to add refrigerant to restore cooling and would like an estimate to replace the mini split. The system serves a 200sq foot insulated shed in the yard that is being used as a home office. It’s currently a 115v Mr cool wall mounted on the exterior of the shed. After we added 2 lbs of refrigerant, restored cooling and dropped supply temp from 72 down to 39 degrees, system cooling. Call complete.
