Arrived for AC maintenance today. Started at furnace and checked static pressure, temperature splits, drains, filter, blower wheel, blower motor. Static is failing at this time, a field supervisor will be out to discuss. Put in our high velocity filter to ease some of the pressure. Wheel is starting to collect dust and could be cleaned. At the ac unit refrigerant was good. Capacitor is reading within specs. Running amps are good. I rinsed coil clean. System is running upon leaving. Thanks for choosing LBA.
