How much does it cost to install a standby generator at home?

The cost to install a home standby generator is confirmed after an on-site assessment and varies with generator size, fuel setup, electrical work, and permitting. The biggest driver is the generator’s capacity and any gas line or meter changes needed to supply it. Most installations take 1–2 days, with about 4 hours of planned power downtime, and city permits typically add about 4 weeks lead time. Our team routinely manages permitting and inspections across the Garland area.

Key factors that drive price:

• Generator capacity (kW) and Kohler model selection
• Gas line or fuel supply work to meet demand
• Electrical scope: automatic transfer switch, panel/meter upgrades, surge protection
• Installation complexity: pad, placement distance, and wiring run length

All installs include a 5-year parts and labor warranty, plus the first year of service; a 5-year maintenance plan is available. Current offer: $500 off Generator Installation.
