When a storm knocks out the power, a generator is the difference between a minor inconvenience and a freezer full of spoiled food and a dark, cold house. But which type is right for you — a portable unit or a permanent standby system?
Here’s an honest comparison of cost, power, and convenience to help you choose the right backup for your home around Berryville and Clarke County.
Why backup power matters in our region
Summer storms and winter weather across Northern Virginia and the panhandle regularly cause outages. Backup power keeps your heating and cooling, refrigerator, well pump, sump pump, and medical equipment running when the grid goes down — which is about more than comfort.
Portable generators — pros and cons
Portable generators cost less up front and can be moved or stored. The trade-offs: they must be started and refueled manually, run on gasoline that you have to keep on hand, sit outside in the weather, and power only what you can safely connect. They should never be plugged into a regular outlet to backfeed the home — that’s a serious hazard.
Standby (whole-home) generators — pros and cons
A standby generator is permanently installed outside and wired into your home through an automatic transfer switch. When the power fails, it starts on its own — usually within seconds — and runs on natural gas or propane, so there’s no refueling. It costs more to install but delivers hands-off, whole-home backup. As an authorized dealer, we install and service standby systems.
Sizing: what do you actually want to run?
The right generator size depends on what you need to power. Some homeowners only want the essentials — refrigerator, furnace fan, a few lights, and a sump or well pump. Others want the whole house, including central air. A licensed electrician calculates the load so your generator is neither undersized nor overpriced.
The transfer switch — don’t skip this
A transfer switch safely connects your generator to your home’s wiring and prevents backfeeding power onto the utility lines — which can injure or kill line workers and damage your equipment. Standby systems use an automatic transfer switch; portable setups can use a manual transfer switch or interlock. Either way, this must be installed by a licensed electrician.
Installation, permits, and placement
Standby generators require proper placement away from windows and doors, a fuel connection, the transfer switch, a permit, and an inspection. We handle the full installation and coordinate the fuel and electrical work so the system is safe and code-compliant.
Maintenance and safety (carbon monoxide)
Every generator produces carbon monoxide and must run outdoors, well away from the home — never in a garage, even with the door open. Standby units self-test and need periodic service; portable units need fuel stabilizer and regular run-ups. We offer maintenance to keep your system ready when you need it.
Frequently Asked Questions
How long can a standby generator run?
On natural gas, it can run for days because it’s connected to your gas supply. On propane, runtime depends on tank size. Portable units run only as long as you keep adding fuel.
Can I plug a portable generator into my dryer outlet?
No. Backfeeding through an outlet is dangerous and illegal. You need a proper transfer switch or interlock installed by a licensed electrician.
What size generator do I need?
It depends on the loads you want to cover. We perform a load calculation and recommend the right size — no guesswork.
