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.

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.

Permit requirements for whole-house generator installations vary by municipality. Because installations include electrical integration and may include gas piping, our technician will confirm any needed permits or inspections during your in-home assessment. Roman provides turnkey installation by certified electricians, including transfer switch work and full system integration. We install and service Briggs & Stratton and Generac systems, with natural gas or propane options. We serve Milwaukee, Racine, and nearby communities. Timelines depend on site conditions and local approvals.
