In order of frequency based on thousands of service calls in the South FL region — the most common issues first. Your Davie technician will diagnose the real cause in under 30 minutes.
Tripped breaker

When Davie homeowners should replace instead

- Repair is under $1,500

- Rest of the system is healthy
