The best standby generator installation comes down to correct sizing, a code-compliant automatic transfer switch, properly sized gas, and safe clearances — all permitted and inspected. The generator brand matters far less than whether the load calculation and the transfer switch were done right. That's where good installs separate from the ones that trip, starve for fuel, or fail inspection.
This is a homeowner buying guide. At the end, we cover the kind of website and lead system we build for generator and electrical contractors.
Whole-home or essential circuits only. Essentials often need 10–14 kW; whole-home for an average house is commonly 18–26 kW. A real load calculation should come before any quote.
An automatic transfer switch disconnects from the grid and starts the generator safely. It's the heart of a code-compliant install and protects line workers from backfeed.
Natural gas or propane, sized so the unit gets full flow under load. An undersized gas run is a common reason a generator runs rough or shuts down.
Manufacturer and code distances from windows, doors, and the structure, on a level pad with proper exhaust routing. Inspectors check this closely.
A permanent standby generator is not a DIY install — the transfer switch ties into your main panel and the unit needs a gas connection, both licensed and permitted. Here's the honest DIY line:
If a portable unit and an extension cord cover your needs during rare outages, you may not need a standby system at all.
A standby generator is a high-ticket, considered purchase — homeowners research for weeks before they call. A page like this, plus fast lead capture, is how you win that research phase. Here's what installers say.
We don't post stock testimonials. On a 15-minute call we screen-share the real dashboards behind our own businesses — live leads, rankings, and the exact page that produced each one. See the proof →
Plans start at $249/mo for a hand-built site plus AI lead capture and hosting, $597/mo with the SEO content engine and lead attribution, and from $1,750/mo for the full CRM and reputation stack. Month-to-month, you own it, one company per market. We run our own cleaning and HVAC companies on the same stack. See electrician website design, electrician SEO, and the AI receptionist.
Essentials only often run 10–14 kW; whole-home for an average house is commonly 18–26 kW. The right answer comes from a load calculation, not a rule of thumb.
Not the full job. The transfer switch ties into your main panel and the unit needs a gas line — licensed, permitted work nearly everywhere. Backfeeding without a transfer switch is dangerous and illegal.
A whole-home standby system typically runs $7,000–$15,000 installed. Gas run length, panel upgrades, and site work move the price the most.
