1. Observe and protect
Document symptoms, limit further damage where it is safe to do so, and collect relevant history.
2. Evaluate the house and site
Electrical panel capacity, transfer-switch placement, fuel source, local permitting, and which circuits genuinely need backup power all shape a sound generator installation plan.
3. Get the scope in writing
Spell out prep, protection, materials, access, permits, testing, cleanup, finish work, exclusions, and change-order pricing.
4. Weigh what's actually proposed
Verify credentials, then compare the reasoning behind each bid, not just the total.
5. Confirm the close-out
Testing, cleanup, paperwork, warranty terms, and ongoing maintenance should all be confirmed before calling the job done.
