Arrived for ac maintenance today. Started at furnace and checked static pressure, it is running at its max rating. Checked blower speeds and adjusted them to match the outdoor unit. Blower wheel is clean. I changed furnace filter. At the condensing unit all pressures and charge look good. All electrical components are running properly. I rinsed coil clean. My field supervisor will be out later today to go over airflow and cleaning options. System is running upon departure. Thanks for choosing LBA.
