AC Repair. Performed VIP spring maintenance on two 2014 Lennox straight cool with furnace systems. Before performing system check I cleaned both condensers with water. Both units were coated with dust, dirt, and hair. After cleaning condenser coils I performed system checks for both systems. The unit for upstairs is having its TXV freeze up as well as the compressor is making a metal on metal noise. The unit for the downstairs was low on Freon and is making TXV freeze up as well. I suspect the unit for the downstairs to have a leaking coil because of the low Freon level.
