Arrived for maintenance on 3 systems. I first checked the old Lennox that cools the basement. It’s low on R-22 refrigerant. You did not want anyone out to discuss replacing, you are running it until it’s done. At the other two furnace running amps are good. Blower wheels are clean. There are 20-21 degree temp splits. At the condensing units all pressures and charge are good. All electrical components are running within manufacturing specs. I rinsed all coils clean. Systems are running upon departure. Thanks for choosing LBA.
