Most homeowners invest between $5,000 and $25,000 for a fully installed whole house generator, with installation costs varying significantly based on your specific setup. The right number for your home depends on the size of your generator, your home's electrical needs, and any panel upgrades required. We're happy to walk you through a free, no-obligation quote so you know exactly what to expect.
It depends on what you want to keep running. To determine the right generator size, list the essential appliances and electronics you'd like to keep powered during an outage and add up the total wattage. A generator's power output is measured in kilowatts, and larger kilowatt ratings mean more of your home can run at once — whether that's everything, or just the circuits you can't live without. Our electricians will calculate your home's actual load and recommend the right fit — no guesswork required.
In most cases, yes. Generator installations typically require wiring and fuel line work that must be handled by a licensed electrician or HVAC technician, along with permits that account for setbacks from property lines, windows, and doors, plus local noise ordinances. We handle the permitting and inspection process for you, so it's one less thing on your plate.
Placement matters for both safety and performance. Most standby generators must be placed at least 5 feet from the house and 18 inches from windows, with enough clearance for airflow and access for future maintenance. Our team will find a spot that satisfies code, keeps noise manageable, and still works with your landscaping.
That depends on the type of system you choose. An automatic standby generator senses an outage and switches on within seconds — no action needed from you. A portable generator, on the other hand, requires manual setup and startup each time. If hands-free reliability matters to you, standby is the way to go.
A transfer switch safely reroutes your home's power from the utility grid to your generator, preventing backfeed that could endanger utility workers or damage your equipment. Without one, you can't legally or safely connect a standby generator to your home's electrical panel. We install transfer switches that meet local code and ensure a smooth, automatic transition the moment the power goes out.
A few warning signs point to repair: the unit fails to start during a scheduled self-test, runs but doesn't reach full power, or throws an error code on the control panel. If your generator is well past its expected service life and repairs are becoming frequent or costly, replacement may make more financial sense. Our electricians can diagnose the issue and give you an honest recommendation either way — no upselling, just what actually makes sense for your system.
With regular maintenance, a quality standby generator is built to last for years of dependable service — many manufacturers reference maintenance intervals around 200–500 hours of continuous use before an oil change or service check is required. Staying on top of routine maintenance, like the plans we offer, is the single biggest factor in how long your system lasts and how well it performs when you actually need it.
