Arrived for ac check on 3 systems. Checked static pressure, the main floor and the upstairs systems are failing static. The master bedroom system is passing. All blower wheels are clean. Motor amps are within specs. Temp splits are all at 20 degrees which is good. Changed all filters. At the condensing units all systems have good pressures and charge. All the electrical components are running within manufacturing. I clean out the inside of the units and rinsed coils clean. All systems are running upon departure. Thanks for choosing LBA.
