When I arrived the blower motor was running with no call. This is a 454b system. I checked the evaporator for any signs of a leak and did not locate anything. I started the system back up and reset the sensor in the control board ran the system in heating and cooling. I received a 22 degree temperature split on the cooling side and the pressure at the out door unit within range. Tested system in heating and function also and it was all within limits. At this time everything is running as it should be
