Arrived for ac check today. Started at furnace and checked static pressure, it’s running under the max rating. I found the blower wheel was dirty, the indoor coil was very dirty, the drain pain is dirty, and the ducts were dirty. My field supervisor, Rainer, is coming down to go over best solutions for you. At the outdoor unit compressor and fan amps are good. Capacitor tested good. Refrigerant levels are showing low, but this could be caused by the dirty system. You would need to get system cleaned then recheck levels. System is running upon departure. Thanks for choosing LBA.
