Standby Generator Maintenance & Repair

A generator that hasn’t been serviced is a generator you’re hoping works, and hope isn’t a plan when it’s -20F and the power’s been out for six hours. We service and repair standby generators across the Mat-Su Valley, whether we installed yours originally or not.

Why Generator Maintenance Matters More Here

Alaska winters are hard on equipment. Cold starts, condensation, long stretches of sitting idle between real outages, all of it takes a toll on a generator that isn’t getting regular attention. Most warranty coverage (Cummins included) requires documented annual maintenance to stay valid, so skipping service doesn’t just risk a failed start, it can cost you your warranty too.

What Our Generator Service Includes

• Full operational testing, running your unit under load, not just a startup check
• Battery inspection and replacement when needed, a dead starting battery is one of the most common reasons a standby generator fails to kick on
• Fuel system inspection, checking lines, filters, and connections for gas, propane, or gasoline-fueled units
• Transfer switch testing, confirming your transfer switch is switching cleanly, since a generator that runs fine but won’t connect to your panel doesn’t help you
• Oil and filter changes on units that require them
• Diagnostic repair for generators that are failing to start, tripping, or running rough, whether it’s a Cummins unit or another brand

Cummins Warranty-Compliant Service

As an authorized Cummins dealer, we service Cummins units to the standard required to keep your extended warranty intact, and we’ll tell you honestly if something’s under warranty versus an out-of-pocket repair.

We Service What We Didn’t Sell, Too

If another company installed your generator and you’re not getting the service or the callbacks you deserve, we’re happy to take over. A lot of our maintenance customers came to us after being let down elsewhere, that’s a big part of why we take this seriously.

How Often Should You Service Your Generator?

We cover this in full here, short answer: most standby units need annual service at minimum, with additional checks recommended after any extended run during a real outage.

Frequently Asked Questions

My generator won’t start, is that a maintenance issue?

Do you service generators you didn’t originally install?

Yes, we service most standby and portable generator brands, not just the Cummins units we sell.

How much does generator maintenance cost?

It depends on your unit size and whether repairs are needed beyond routine service. We’ll give you a clear quote before any work begins.
