Standby Warranties and Service Plans, at a Glance
A whole-home standby generator carries a manufacturer's warranty whose length and coverage vary by maker — so the document that came with your unit is the one that counts. This guide explains that warranty, extended coverage, and yearly service plans, plus why a professional install keeps your warranty valid, how registration and records protect you, and which parts are covered defects versus wear items like the battery. There's a printable 29-page version up top.
Common Questions
1 How long is a standby generator's warranty?
It varies by maker and model, so a number quoted here could be wrong for your unit — your own warranty document is the authority. It typically covers defects in the engine and generator parts, not routine upkeep or wear items. Read the coverage length and the conditions, and keep the booklet where you can find it.
2 Does installing it myself void the warranty?
Usually, yes. Most makers require a qualified, often authorized, installer, and the electrical and gas work must be licensed and permitted regardless. A do-it-yourself install risks both your safety and your coverage — it's never the place to cut a corner.
3 What's the difference between a warranty and a service plan?
A warranty is the maker's promise to fix covered defects for a set time. A service plan is a yearly arrangement — usually with your installer — to perform the routine maintenance the unit needs. They work best together: the plan keeps the unit ready and documents the upkeep many warranties require.
4 Is the starting battery covered?
Typically not. The battery is a wear item and a common failure point, so plan to replace it over the years as part of normal ownership rather than a warranty claim.
5 Do I need to register my generator?
Yes — treat it as a must. Registration links the unit's model, serial number, and install date to you, and many makers expect it for full coverage. It takes a few minutes and makes any future claim far smoother. Keep the confirmation with your records.
6 How do I make sure I don't lose my coverage?
Install it right through an authorized, licensed, permitted job; register the unit; keep your receipts, permit, and a service log; and have it maintained on the maker's schedule. Our maintenance guide covers the upkeep itself in plain English.
Would You Rather I Just Help?
Warranties and service plans are exactly the kind of fine print I love to make plain — I don't sell generators or coverage, so it's just honest help. I'll read your documents with you, get the unit registered, and set up a simple records folder so nothing slips. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
