Carrier Considerations
Downtime diagnostics and common repair requests we manage along the industrial corridor for Carrier systems:
- Run capacitor bulge on outdoor units
- High discharge temperature (scroll compressor overload)
- PCB relay sticking
- Capillary bypass tube vibration leakage
Hitachi Considerations
Downtime diagnostics and common repair requests we manage along the industrial corridor for Hitachi systems:
