Most whole-home standby generator projects in our area land between $12,000 and $16,000 installed. Here's the fuller picture: Essential-load or smaller standby system: about $9,000–$12,000 installed. Covers the circuits that matter most — heat, refrigeration, well pump, sump pump, lighting, internet. Typical whole-home 18–24 kW system: about $12,000–$16,000 installed. This is where most homes land. Larger 24–26 kW or more involved installation: about $14,000–$20,000+, typically driven by longer gas and electrical runs, difficult access, or heavier loads like central air and a pool. Large luxury homes, liquid-cooled units, and highly complex systems: $20,000 and up. What moves the number most is site conditions rather than the generator itself — distance from the panel and gas meter, whether your gas service can carry the load, propane tank requirements, and permitting. We'll give you a firm written price after a free on-site consultation, and financing is available. Call (774) 563-4219.
