A generator that fails when you need it is worse than no generator at all. Peak Power Systems provides factory-authorized Generac maintenance, annual service, and warranty repairs across Folsom, El Dorado Hills, Roseville, Auburn, and the Sacramento Foothills. We're the local team you call when your unit needs a tune-up before fire season, when the Mobile Link app flags a fault, or when your generator won't start during an outage.
Generac's manufacturer schedule calls for a full service every 200 operating hours or annually, whichever comes first. Sacramento Foothills homes that experience multiple PSPS events per year burn through service intervals faster than the national average, so we recommend an early-spring visit — before Diablo winds arrive.
Problems We Solve
The specific power reliability challenges Sacramento Foothills homeowners face — and exactly how we address them.
Failed self-test alerts
Generac units run a weekly self-test. When it fails, Mobile Link sends a notification — and we come out to diagnose before you actually need the unit.
Old, degraded batteries
Standby generator starter batteries typically last 2-3 years. A dead battery = no start when PG&E cuts power. We replace on schedule, not on failure.
Oil, filters, and spark plugs
Just like a car, generators need scheduled oil changes, filter swaps, and plug replacements. Miss these and warranty coverage can lapse.
Fuel regulator issues
Propane and natural gas regulators drift over time. We test fuel pressure and adjust for seasonal changes so your unit runs clean.
Rodent damage
Foothill properties see mice and rats build nests inside generator enclosures. We inspect and clean during every service visit.
Control board or transfer switch failures
Full diagnostic reads: fault codes, engine sensors, transfer switch operation. We repair on-site when parts are on the truck.
Benefits
Annual maintenance plans
Fixed-price yearly service that includes oil, filters, plugs, coolant check (liquid-cooled), battery test, and full diagnostic.
Priority emergency dispatch
Maintenance customers get 24/7 priority response — front-of-line during PSPS events and heat waves.
Warranty preservation
We register your service with Generac to keep your 5-year manufacturer warranty valid and eligible for warranty repairs.
Mobile Link monitoring
We help you configure Generac Mobile Link so you (and we) get real-time alerts on any fault, low battery, or missed self-test.
Parts on the truck
Common Generac parts — batteries, oil, filters, sensors, regulators — travel on our service trucks so most repairs finish first-visit.
Loaner generators
If your unit needs off-site repair, we can deploy a portable loaner during major PSPS events so your home stays powered.
Our Process
Schedule Service

What a Peak Power annual service includes
Oil and oil filter change (5W-30 synthetic or Generac-spec conventional), air filter replacement, spark plug replacement, valve clearance check on older units, battery load test and terminal cleaning, fuel line and regulator pressure check, transfer switch cycle test, exhaust and enclosure inspection, Mobile Link connectivity verification, and a full fault code read. Total time on-site is typically 60-90 minutes.
When to call for repair (not just maintenance)
Call us right away if your Mobile Link app shows a persistent fault, if the generator fails a weekly self-test, if you hear unusual noise during operation, if the unit runs but doesn't transfer the load, if the AC ripples or trips when the generator starts, or if you smell fuel around the enclosure. These aren't wait-and-see items — they're wait-and-your-generator-fails-during-the-next-outage items.
Emergency repair
24/7 emergency dispatch is available for existing maintenance customers across our service area. Common Generac failures — dead starter battery, oil sensor trigger, low fuel pressure, control board fault — are repaired on the first visit from parts we stock on service trucks. For rarer failures needing a factory-order part, we deploy a portable loaner generator during major PSPS events so your home stays powered.
