Generator Maintenance Plans: What It Costs and How to Choose a Provider

What's included

Scheduled oil and filter changes, battery testing, exercise-cycle verification (most units self-test weekly, but a technician should confirm it's actually happening), and a pre-storm-season inspection.

Typical cost

$150–$400/year for a basic plan; $400–$800/year for a comprehensive plan including parts.

Actual pricing varies by home, region, and system size, this is a general range, not a quote. Get quotes from at least two or three license-checked local installers for a number specific to your situation.

How to choose

Ask what's covered vs. billed separately (many plans exclude battery replacement), and whether the plan includes priority emergency-repair scheduling — this matters most during storm season when everyone needs a technician at once.

Questions to ask before signing

• Is your license current, and can I verify it independently?
• Who pulls the permit, you or me, and is that included in the quote?
• What does the workmanship warranty cover, separately from the manufacturer warranty?
• What's the expected timeline from signing to completed, inspected work?
• Is the estimate itemized, or a single lump-sum number?

Warning signs to watch for

• Reluctance to provide a license number or discuss permitting at all.
• Pressure to sign the same day, or pricing that's only available "today."
• No written contract, or a contract with no itemized scope of work.
• Requests for full payment upfront, before any work has started.
