Arrived for ac check today. Started at furnace and checked static pressure, it is running over max. We have discussed with you before. Blower wheel is clean. Motor amps are within range. There is a 23 degree temp split. I changed furnace filter today as well. At the condensing unit compressor and fan amps are good. I added a little bit of refrigerant to get pressures and charge correct. When systems are installed in winter, we have to do this sometimes. Pressures and charge are correct. I rinsed coil clean. System is running upon departure. Thanks for choosing LBA.
