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

Home standby generator installation cost is confirmed after an in‑home assessment because equipment size and project scope vary by home. The biggest driver is generator capacity and whether you power the whole house or only essential circuits. Our licensed electricians have deep DMV experience delivering safe, code‑compliant installs. We size for both running load and motor startup surge, not just the label wattage, so the system doesn’t stumble when big appliances kick on.

Key cost drivers include:

• Power capacity (kW) and whole‑home vs. essential‑loads configuration
• Fuel type (natural gas vs. propane) and any gas piping or tank work
• Transfer switch choice (automatic vs. manual) and panel/wiring upgrades
• Placement, pad, ventilation clearances, and trenching or conduit runs

A current site offer provides $500 off any complete standby generator installation with code 500STANDBY, subject to listed conditions and expiration.
