About scope and pricing
Is the transfer switch included in the quoted price, or billed separately? Does the quote include permit filing and inspection scheduling? What's covered if a panel upgrade turns out to be necessary once work starts? Getting clear answers here is what actually makes quotes comparable across contractors.
About licensing and experience
Is the installer licensed for both electrical and gas/propane work, or do they subcontract part of the job? How many similar installations have they completed in your area, where local permitting quirks are already familiar?
About warranty and ongoing support
What's the manufacturer warranty, and does it require a specific maintenance plan to stay valid? Who do you call if something goes wrong after installation — the installer, the manufacturer, or a separate service network?
About references and past work
Can they provide references from recent, similar installations in your area — not just a general portfolio? Asking to see (or at least hear about) a completed project of similar scope and site complexity gives a more concrete sense of what to expect than marketing materials alone.
