Coverage
Warranty and service
There are two separate warranties on any installed generator: the manufacturer covers the machine, and the installer covers the installation. Knowing which is which saves you a lot of time when something needs attention.
The manufacturer warranty
The air-cooled Connect range — RS13A, RS17A, RS20A and RS20AC, plus their extreme cold weather versions — carries a 5 year / 2,000 hour limited warranty as standard. Whichever limit you reach first ends the term.
Coverage inside that period is not uniform, and the difference matters: parts are covered for the full five years, while travel and labor are covered for the first two. A failure in year four means the part arrives at no cost, but the visit does not.
The RA automatic transfer switch carries its own separate 2 year warranty. It is a distinct product with a distinct term, so a switch fault in year three is not covered by the generator warranty even though the two were bought and installed together.
Extended warranty options are available, and they are worth pricing at the point of sale rather than after something has failed.
Buying through an authorized dealer is what makes any of this valid. Gray-market equipment from an unauthorized reseller frequently is not covered, and owners usually discover that at the worst possible moment.
The liquid-cooled range is different, and materially so. RS25 through RS150 carry a 2 year standby base warranty, not five. If you are comparing a 20kW air-cooled unit against a 25kW liquid-cooled one, that gap belongs in the comparison alongside the price. Extended warranty options are available on both and are worth pricing at the point of sale.
Air-cooled figures come from the Cummins specification sheet for the Connect range (NAS-6254-EN). Liquid-cooled figures come from the individual RS-series sheets published by Cummins. Diesel terms are still unconfirmed — do not quote them until you have checked the dealer portal.
Our installation warranty
We warrant our own workmanship: the gas line, the electrical tie-in, the transfer switch installation, the pad and the commissioning. If something we installed fails because of how we installed it, we come back and fix it and there is no invoice.
This is the practical argument for buying equipment and installation from the same company. When the sale and the install are split across two businesses, a fault becomes a question of whose fault it is, and you are the one holding both phone numbers.
What voids coverage
Skipped maintenance is the leading cause. A standby generator needs oil, filters and an annual inspection on a defined interval; documented service is normally required for warranty claims. Unauthorized modification and improper fuel are the other two common causes. See what a service visit covers.
Who to call
Call us first, at any time, for anything. If it is a manufacturer warranty matter we open the claim and manage it. If it is an installation matter we handle it directly. You should not have to work out which category your problem falls into — that is our job.
Questions
Does buying from an online reseller void the warranty?
Buying from an unauthorized reseller frequently means the manufacturer warranty is not honoured, and self-installation or installation by an unlicensed party can void it as well. If a price online looks materially below what authorized dealers show, that is usually the reason.
Do you service generators you did not install?
Yes, subject to inspecting the existing installation first. We need to see how it was put in before we take responsibility for how it runs.
What does maintenance cost?
It depends on the unit and the interval. We quote maintenance plans at handover and you are never obligated to buy one from us — but you do need the work done by someone, and documented, to keep coverage intact.
