How do I choose the best generator installation & service contractor in Dayton?
Look for contractors with specific experience in commercial electrical (not just residential). Verify their state license, insurance, and bonding, and confirm they're certified and experienced with your electrical system. Check reviews from similar commercial properties. Ask about their workmanship warranty and their typical response time for follow-up issues.
How long does generator installation & service typically take?
The timeline depends on the size and complexity of your electrical system and the scope of work. Simple repairs often complete in a few hours. Larger installations and replacements may take several days to a few weeks. Emergency service typically stabilizes the problem within hours even when the permanent fix requires returning with materials.

Contact your insurance provider and ask specifically about coverage for your electrical system. A documented inspection report strengthens any claim you file.
