Home Generator Repair FAQs
Frequently asked questions about Home Generator Repair
Questions San Dimas, CA homeowners and businesses ask most about Home Generator Repair — and clear, honest answers.
Talk to a real personWhat is the difference between a standby generator and a portable generator?
A standby generator is permanently installed, runs on natural gas or propane and starts automatically when the power fails. A portable generator is moved by hand, runs on gasoline or propane, and you start it and connect it yourself.
Why does my generator run but the house has no power?
The usual causes are a failed transfer switch, a tripped breaker, a damaged outlet or a failed voltage regulator. Because it involves your electrical system, it should be checked by a qualified person.
Why does my generator surge or stall?
Surging is often caused by dirty fuel, a clogged carburetor or filter, or a fuel supply problem. Stalling can also come from low oil, an overload or a failing sensor.
Can I run a generator in a garage or near the house?
No. Generators produce carbon monoxide, which can kill. Never run one indoors, in a garage or in a partly enclosed space. Keep it outside and well away from windows, doors and vents, and install carbon monoxide alarms in your home.
How do I get started?
Call (877) 884-0342, describe your generator and what it is doing, and ask about an estimate and availability for your area.
