Arrived for ac check today. Started at furnace and checked static pressure, it is failing. Heat exchanger is starting to rust and has hot spots all over. Blower wheel is caked in dust. Motor amps are good. Temp split was only 16 degrees, 20 is where it needs to be. At the condensing unit the coil was caked in debris, I cleaned it. pressures and charge looked ok. Electrical components are running properly. Unit is out of level. Contactor is burnt. System is running upon departure. Thanks for choosing LBA.
