The most common reasons a Generac standby generator won’t start are simple to check first. In Milwaukee and Waukesha homes, our technicians most often find battery or setup issues.
- Weak battery or corroded battery cables.
- Unit not in Auto mode.
- Worn spark plugs (replace annually).
- Low oil or coolant, or visible leaks.
- Dirty air intakes or exhaust areas.
- Transfer switch not sending the start signal.
- Dirty/damaged AC wiring or connections.
- Unit out of level or casing damage.

"The installation was quick and sharp." — Dennis M.
Change the oil in your standby generator once a year. Our Generator Annual Visit Program includes a complete oil change, plus annual oil filter and spark plug replacement. We also inspect for leaks, perform battery and transfer switch tests, and clean the unit to keep it outage-ready. Service is available in Milwaukee and nearby cities. Note: the annual plan does not cover battery replacement costs.

Standby generator repair pricing is finalized after an on-site diagnosis because parts, labor, and generator size drive total cost. Our team services the Milwaukee area and supports automatic standby systems we install and maintain, including major brands we carry. A licensed technician will check fuel, oil, and controls before quoting work.
Typical cost variables include:
- Battery replacement or charging-system repair
- Control board, sensor, or wiring faults that require OEM parts
- Fuel system issues on natural gas or propane lines
- Engine, alternator, or transfer switch repairs
Repairs suit single failed parts; consider replacement for repeat failures or major engine or alternator damage. Home Protection Plan members receive 10% off services and repairs. If your generator shows alarms, won’t start, or trips during transfer, book a diagnostic visit before the next storm.

The cost to install a home standby generator is confirmed after an on-site assessment because equipment size, fuel type, and installation needs vary. The biggest driver is the generator’s kilowatt capacity required to handle your home’s loads. Roman Home Services offers Generac and Briggs & Stratton options and provides certified, turn-key installation including gas piping, so your quote reflects the complete system, not just the unit. Our team regularly installs and services standby systems across the Waukesha area. If you’re in our Home Protection Plan, members receive 5% off major equipment installations.
Your final price typically depends on:
- Generator size (8–60 kW options)
- Fuel source and piping distance (natural gas or LP)
- Transfer switch and electrical upgrades
- Site location, pad, and venting clearances
Book a sizing visit to get a clear, fixed price in writing before any work begins.
