Arrived for ac check today. Started at furnace and checked static pressure, it is failing. Motor amps are high, but still under max. Blower wheel is dirty. The indoor coil is coated with debris. There is a 22 degree temp split. I changed furnace filter. At the condensing unit all pressures and charge look good. All electrical components are running within manufacturing specs. I rinsed and cleaned coil. System is running upon departure. Thanks for choosing LBA.
