Electrical Problems Often Look Like HVAC Problems
Many no-cooling calls begin with a control or electrical failure. The right diagnosis requires checking the circuit instead of replacing components based only on symptoms.
Common Components
- Thermostats and low-voltage wiring
- Capacitors and contactors
- Relays and transformers
- Indoor and outdoor fan motors
- Control boards and safeties
Otis Services uses electrical testing as part of the broader diagnostic process when the symptoms point that direction.
