Cummins Reviews

Cummins home generators are sold through authorized dealers and select online retailers. Dealers can help with sizing, pricing, installation estimates and ongoing maintenance. To get started, you can use the dealer locator on Cummins’ website to find a dealer near you.

A local dealer can assess your home’s power needs, recommend a generator size and provide a quote. Dealers typically handle permitting, installation, warranty service and ongoing maintenance.

Cummins doesn’t offer direct-to-consumer installation services. All purchases and installations are handled through its dealer network, so your experience may depend in part on the dealer you choose. It’s a good idea to read local reviews and get multiple quotes before committing.

Cummins offers a range of residential generator solutions designed to keep your home powered during outages. The company's lineup of products and services includes:

• Home standby generators: Cummins home standby generators are installed permanently outside your home and connected directly to your natural gas or propane supply. They start automatically when the power goes out and shut off when utility power returns. Models range from 13 kilowatts (kW) to 20 kW for most residential applications, with larger units available for bigger homes.
• Portable generators: Cummins also offers portable generators for temporary power needs. These units run on gasoline and provide power for essential appliances during short outages or for outdoor use. Portable models are less expensive upfront but require manual start-up and fuel storage.
• Transfer switches and accessories: Cummins standby generators come with an automatic transfer switch that safely disconnects your home from the utility grid and switches to generator power. This prevents dangerous backfeed to utility lines and allows the generator to power your home safely.
• Mobile Link remote monitoring: Cummins offers the Mobile Link remote monitoring system, which lets you check your generator’s status, receive maintenance alerts and track run history from your smartphone. The system connects via Wi-Fi or cellular.

Cummins dealers typically list home standby generators between $3,000 and $5,000 for the unit alone, depending on output capacity. Installation adds $3,000 to $5,000 or more, depending on whether you need a new gas line, transfer switch or electrical panel upgrades. Total installed cost commonly falls between $6,000 and $12,000. Portable generator models are significantly less expensive, generally ranging from a few hundred to a couple of thousand dollars.

Cummins doesn’t sell home generators directly to consumers, so pricing is set by authorized dealers. Your final cost will depend on the unit size, installation complexity and your location. To get accurate pricing, you can request a free quote through an authorized Cummins dealer, who will assess your home’s power needs and provide an itemized estimate.

Operating costs during an outage depend on your local natural gas or propane rates and how much power you draw. Natural gas standby generators are generally inexpensive to run because they connect directly to your utility supply and don’t require separate fuel storage. Annual maintenance, which is required to keep your warranty valid, typically costs $150 to $300.

If you use propane, you will need a properly sized propane tank on your property. Tank rental or purchase costs vary by supplier and region. Some utility companies and state programs offer rebates or incentives for backup generator installation, so it’s worth checking local options before purchasing.

Cummins recommends annual professional maintenance for its home standby generators regardless of how often the unit runs. This keeps the generator ready for outages and is typically required to maintain your warranty.

Annual service typically includes an oil and filter change, spark plug inspection, air filter replacement, battery test and a full operational check. Cummins standby generators also perform a weekly self-test cycle automatically, running for a few minutes to keep the engine conditioned and alert you to any issues before an actual outage.

If you have a propane-fueled unit, you should also monitor your tank levels and schedule refills before winter or storm season. Keeping your tank at least 20% filled helps ensure the generator can run through an extended outage.

You can schedule maintenance through an authorized Cummins dealer. The Mobile Link monitoring app can also send service reminders and alert you when the generator detects a fault, making it easier to stay on top of upkeep.

Cummins home standby generators come with a limited warranty. Its 13-, 17- and 20-kW models include a five-year or 2,000-hour limited warranty, while larger 25- to 125-kW models include a two-year limited warranty. Automatic transfer switches come with a two-year warranty.

Extended warranty options may be available through authorized Cummins dealers. Some extended warranty options can provide coverage for up to 10 years, but availability and terms vary by model and dealer.

For full warranty terms, exclusions and claim requirements, ask your local authorized dealer before purchase.

Yes, Cummins can be worth it if you’re looking for a home backup generator from a well-established brand. Its standby generators offer relatively quiet operation and turn on automatically during an outage.

The main trade-off is cost. Cummins generators sit in the mid-to-upper price range compared to some competitors. But if you prioritize brand reputation, quiet operation and a national dealer network, Cummins is worth considering. Its generators are most cost-effective for homeowners in areas with frequent or prolonged outages where the convenience and reliability justify the upfront investment.
