Exhaust Fan Repair
Troubleshooting and Repairing Exhaust Fans
Common Exhaust Fan Problems
Exhaust fans operate in warm, humid environments that can gradually wear down components. Common issues include the following:
- Fans that fail to start or lose power intermittently
- Reduced airflow or poor ventilation performance
- Loud rattling, humming, or grinding noises during use
- Faulty switches or wiring connections
- Motors that overheat or stop responding
If left unresolved, these problems can lead to moisture buildup, mildew growth, and reduced indoor air quality.
Our Diagnostic and Repair Process
MAD Energy NW performs thorough inspections to identify electrical or mechanical faults within the fan system. Using proper diagnostic tools, we test voltage, airflow, and wiring continuity to locate the root cause of the malfunction.
Our process includes the following:
- Checking for power at the breaker and switch
- Testing motor function and fan blade movement
- Inspecting wiring for corrosion or heat damage
- Replacing worn switches, motors, or connectors
- Verifying quiet and stable fan operation after repair
All repairs are completed according to Washington State electrical codes and manufacturer specifications for ventilation systems.
Preventive Care for Long-Lasting Performance
Regular maintenance helps prevent exhaust fan failures and ensures steady airflow throughout your home. Cleaning fan housings, tightening connections, and testing controls periodically keep the system efficient and reliable.
Our electricians can also upgrade older fans to modern, energy-efficient models that provide better noise control and moisture removal.
