When a storm knocks out power across the Upstate, a standby generator can bring essential circuits back automatically. We handle the load review, equipment, electrical work, fuel connection, and startup.
Generator help when you need it
Schedule a generator planning visit. We'll review the power you want to keep on, the fuel source, the site, and what the installation will take.

Backup Power Should Match Your Priorities
Duncan neighborhoods include established homes and newer communities near SC 290. The right backup plan starts with the home's service, the loads you want available, and how larger equipment starts.
One household may want refrigeration, lights, and Wi-Fi. Another may also need cooling, a well pump, or other critical equipment. We help you choose the circuits that matter instead of treating every load in the home the same.
Hurricane Helene showed how widely a regional outage can disrupt Upstate homes. A standby generator cannot prevent storm damage, but it can automatically restore power to the circuits selected for backup after utility service drops out.
Food can spoil and indoor temperatures can become uncomfortable as an outage stretches on. Remote work, schoolwork, security, garage access, and communication can also be interrupted. Backup power keeps a hard day from becoming harder.
Air conditioning, pumps, and other motor-driven equipment need extra power when they start. Several large loads coming on together can overwhelm a generator that looked adequate on paper. We account for that behavior when we size the system.
STANDBY POWER + COMPLETE PROJECT SUPPORT
For a Duncan-area home, we confirm the electric service, backup loads, and available fuel before equipment is selected. Then we coordinate the generator, transfer equipment, electrical work, placement, and startup as one system.
Generator Brands We Install, Service & Repair
The RightFirst Standard
You should not have to coordinate an electrician, gas contractor, equipment installer, and permit process on your own. We keep the complete standby installation under one accountable team.
The generator, transfer equipment, service capacity, and fuel supply all affect the final design. We plan those pieces together and make sure the supported loads match what your household expects during an outage.
Every lot has limits. We account for required clearances, exhaust direction, service access, gas or propane routing, and the electrical path back to the home before the pad and equipment location are finalized.
At startup, we run the generator and verify automatic transfer operation. We show you the normal controls and exercise cycle. We also provide maintenance and repair support after installation.

Generator Questions
We size a generator around the loads you want available during an outage. Heating and cooling equipment, pumps, appliances, and other motor-driven systems can affect the needed capacity as they start and run. We use your household priorities instead of relying on a square-footage rule.
Whole-home backup can fit a home when generator capacity and electrical demand support it. Selected critical-load backup focuses on the systems you decide matter most, such as refrigeration, lighting, internet, cooling, or a well pump. We help you compare both approaches against your expectations during an outage.
A properly installed automatic transfer switch senses an outage and moves supported loads to generator power. It moves those loads back when utility power returns. It also keeps generator power safely separated from the utility connection.
Natural gas and propane are common standby-generator fuel options. We verify natural-gas availability and supply capacity at your address rather than assuming either. If propane is considered, we discuss the tank location and fuel-supply needs for the property.
A standby generator belongs outdoors. We select a location with manufacturer clearance requirements, code considerations, exhaust direction, service access, and the property layout in mind. Tighter sites and homes with community rules may need additional review before we select a location.
Permit and inspection requirements depend on the work involved and the property’s exact location. For a Duncan-area address, we confirm whether Town of Duncan or Spartanburg County requirements apply. We then follow the current permit and inspection requirements for the work involved.
At startup, we run the generator and confirm that automatic transfer operates as intended. Most standby generators run scheduled exercise cycles. They still need routine maintenance based on manufacturer guidance, operating conditions, and model requirements. Regular service can identify concerns before an outage.
We provide maintenance, service, and repair support for installed standby systems. We evaluate the generator’s age, condition, maintenance history, and available parts before recommending repairs. That evaluation helps us explain what the system needs.
