Generator Repair & Maintenance in Sioux Falls, SD
Keep your system ready for the next outage — and we'll come fix it if it isn't.
A Generator Only Helps If It Starts
Standby generators sit outside year-round through South Dakota heat, snow, and everything in between — which means batteries, air filters, and oil need regular attention or the system won't start when you actually need it. We service existing units regardless of who installed them, and we prioritize active outage calls.

When to Call for Generator Repair
Won't Start During an Outage
If your generator failed to kick in the last time you lost power, don't wait for the next outage to find out why.
Weekly Self-Test Errors
Most standby units run a short self-test weekly — an error code or failed test is an early warning sign worth checking.
No Maintenance in Over a Year
Skipped annual service is the most common reason a generator fails right when it's needed most.
Why Sioux Falls Homes Need Backup Power
Outages in Sioux Falls tend to hit when they hurt the most. The May 2022 derecho knocked out power across the city and surrounding towns, some for days. Winter blizzards and ice storms bring down lines when it's 20 below. Spring storms and the thaw cause outages just as sump pumps are working hardest to keep basements dry.
Without power, a gas furnace stops because the blower motor needs electricity. Pipes can freeze within hours, and a finished basement can flood once the sump pump quits. A standby generator restores heat, the sump pump, the fridge and the well pump on its own within seconds.
Common Problems We Fix in Sioux Falls
Cold-start failures
Weak batteries and thick oil cause most winter no-starts. We load-test batteries and fit cold-weather kits where they are needed.
Snow and ice damage
Drifting snow, ice on the enclosure and rodents nesting in for winter can block airflow or chew wiring.
Transfer switch faults
A generator that runs but leaves the house dark usually has a transfer switch or controller problem.
Annual maintenance
Oil and filter, spark plugs, air filter, battery test and a simulated outage, best done in fall before winter storm season.
Most repairs run $150 to $600, and annual maintenance usually runs $200 to $350. We work on Generac, Kohler, Briggs & Stratton and Champion units. Need a new system? See whole-home generator installation or Generac installation in Sioux Falls.

Frequently Asked Questions
When should I service my generator?
Early fall is best, so the unit is ready before blizzard and ice storm season. Once a year is enough for most homes.
Why won't my generator start in the cold?
The most common causes are a weak battery and thickened oil. A battery replacement and a cold-weather kit usually solve it.
Do you repair generators you didn't install?
Yes. We service Generac, Kohler, Briggs & Stratton and Champion standby units, no matter who installed them.
