📍 Serving Greater DFW & North Texas
Sunnyvale sits on the quieter eastern edge of DFW — lower density, larger lots, and the kind of neighbourhood where people settle and stay. What eastern Texas weather systems bring, though, isn't quiet: ice storms and sustained wind events that can knock out power for days at a stretch. A generator changes that equation entirely.

Sunnyvale is in Dallas County, served by Oncor — a provider we coordinate with on every installation we complete in eastern DFW. We know the permit process, the utility requirements, and the range of lot configurations you find in a city that includes both standard subdivisions and larger acreage properties on its edges.
Every installation is performed by a licensed master electrician — not a subcontractor. We are a Generac PowerPro Elite+ dealer for all three major brands.
The same crew that gives you the assessment handles permits, installation, and ongoing service. No handoffs, no subcontractors — one point of contact from the first call to the first automatic test run.
Sunnyvale's larger lots and lower-density homes range widely — from 2,500 sq. ft. properties to bigger custom builds on acreage, some on propane rather than natural gas. Generator sizing here typically lands in the 22–48kW range. We carry all three brands and configure each system for your home's load and fuel source.
America's #1 generator brand. Generac's 22–36kW units cover most Sunnyvale homes, with the liquid-cooled Protector series for larger acreage properties. Available in natural gas and propane, with strong parts and service support across East DFW.

Engineered for demanding homes. Kohler standby units run quietly and reliably under sustained load — well-suited to Sunnyvale's larger lots where a generator may run for days through an ice storm. Available in natural gas and propane across the 20–48kW range.

Sunnyvale's larger lots mean homes vary widely — from 2,500 sq. ft. properties to bigger custom builds on acreage. Sizing depends on square footage, HVAC zones, outbuildings, and whether you're on natural gas or propane. Most installations land in the 22–48kW range, and the free assessment captures the full picture.

Yes. We service all major brands — Generac, Kohler, Champion, Briggs & Stratton and Cummins — regardless of who originally installed them.
Yes. Larger Sunnyvale properties off the natural gas main often run propane, and all three brands we carry offer propane-compatible standby units. We assess your tank capacity and supply line during the home visit to confirm they'll support continuous generator operation, and we'll advise on tank sizing if needed. Larger lots with well pumps or outbuildings may also call for a higher-capacity liquid-cooled unit, which we size during the assessment.
Yes. A natural-gas standby generator runs continuously for as long as the gas supply holds — effectively indefinitely on a utility line. A propane unit runs as long as the tank lasts, which is why we size tank capacity to your expected runtime during the assessment. Either way, the system starts automatically within seconds of an outage and runs until the grid recovers. This is precisely the multi-day scenario standby generators are built for.
