When The Power Goes Out,
Your Home Keeps Running.
A standby generator is permanently installed outside your home and wired into your electrical panel. When the utility drops, it starts on its own within seconds, whether you're home or not.
No extension cords, no gas cans, no scrambling in the dark. Heat, sump pump, well pump, refrigerator, medical equipment, internet and lights all stay on.
Handyside handles the whole project: sizing, permits, the concrete or composite pad, gas line, automatic transfer switch, electrical connection, startup and testing.
Schedule your free in-home estimate and we'll size the right generator for your house and your budget.
Properly Sized For Your Home
We walk your home, review your panel and your must-run circuits, then recommend a generator that actually carries the load, not one that's oversold or undersized.
0% Financing For 36 Months, Subject To Approval
Approved homeowners can spread the investment across 36 months at 0%, so backup power fits the budget before the next storm arrives.
Turnkey Installation, Permits Included
Licensed electricians, gas connection, transfer switch, inspection and a full startup test. We hand you a system that's ready before you need it.
Why Homeowners Install Standby Power
What A Standby Generator
Protects.
Outages in Harrisburg and York rarely arrive at a convenient time. Here's what backup power keeps safe.
Heat & Cooling
Your furnace or AC keeps running, so pipes don't freeze and the house stays livable.
Sump & Well Pumps
No power means no sump pump. A flooded basement costs far more than a generator.
Food & Refrigeration
A full fridge and freezer stay cold through multi-day outages.
Medical Equipment
CPAP, oxygen concentrators and mobility equipment stay powered without a thought.
Work From Home
Internet, computers and lighting stay up so an outage doesn't cost you a workday.
Security & Peace Of Mind
Lights, cameras and alarms stay live, and the system starts automatically when you're away.

Dad's Promise
A Generator Should Come With More Than A Warranty. It Should Come With a Promise.
When Bryan Handyside started the company in 1996, he built it around the standard he would expect for his own family. That same standard guides every installation today.
If we wouldn't accept the work in Bryan's home, we won't accept it in yours. We respect your home, explain before we install, do the work right and stand behind it.
That's Dad's Promise. And it's behind every system we install.
- Locally owned and operated
- All technicians background-checked & drug-tested
- No overtime charges, ever
- Upfront pricing before work begins

"Austin and Sean are great technicians. They did an excellent job first diagnosing what the house needed and then installing a whole house dehumidifier with an air purifier. The house's air quality and comfort level, even in this extreme humidity, has never been better."

"Devin did a great and thorough job replacing our old toilet and installing a new one. He came after hours and had the job completed in no time. Especially considering he also replaced a few other things to ensure the job was done correctly. We were very happy with his service."
