Find & Compare Generator Installers in Your Area!

Generator installers size, place, and connect standby generators that start automatically when the power fails, including the concrete pad, gas or propane line, transfer switch, and permit. Some also set up portable generator inlets. Visitors are here after a long outage, because someone in the home relies on medical equipment, or because a sump pump or freezer cannot be left to chance.

The electrical connection requires a licensed electrician in nearly every state, and the fuel line typically needs a licensed plumber or gas fitter, with permits and inspection for both. Ask whether the installer is certified by the generator manufacturer (it affects the warranty), what the unit will and will not power, and whether the quote covers the pad, fuel line, transfer switch, permits, and start-up. Ask about annual maintenance plans and remote monitoring. Prices depend on generator size, fuel type, and how far it sits from the panel and the meter. For the wiring alone, see electricians; for battery and solar backup instead, solar installers.
