Arrived for ac check today. Started at furnace and checked static pressure, it’s running right at the max rating of .8. Motor running amps are good. There is an 18 degree temp split. Blower wheel is collecting dust. There is bacterial growth on the coil. The ducts are dirty also. At the condensing unit all pressures and charge look good. All electrical components are running within manufacturing specs. I rinsed coil clean. System is running upon departure. Thanks for choosing LBA.
