Backup Power for Real Outages

Power for What Cannot WaitWhen Utility Power Is Out

When an outage cuts utility power in Lyman, the refrigerator stops cooling. Heating or cooling can stop. Wi-Fi and charging disappear. Standby power can keep the systems your household cannot afford to lose running.

A refrigerator and freezer start warming as an outage continues. If your home has a well pump, water at the tap can stop. Without heating or cooling, indoor conditions can become difficult fast.

Without power, Wi-Fi, phones, and security equipment may not work as expected. That can interrupt remote work, school, family updates, and access to information during a major storm.

Medical equipment, refrigerated medicine, or mobility equipment may affect which circuits your household considers essential. We account for those loads during sizing and selected-load planning. Because a standby system takes time to start and transfer power, equipment that requires uninterrupted operation needs its own appropriate backup.

Some Lyman homeowners want whole-home backup. Others want selected circuits for the refrigerator, HVAC, lighting, Wi-Fi, and charging. The best fit is the coverage that lets your household function through a long outage.

The RightFirst Standard

A Better Finished InstallationThe RightFirst Difference

Generator installation goes better when one team owns how the equipment, electrical work, and fuel supply come together. We coordinate the whole job so you are not left managing separate contractors.

01

Matched to the Loads You Need

We match the generator to the loads you need and account for the extra demand created when motors start. That helps prevent a system that looks adequate on paper but cannot support the equipment you expected to use.

02

Clean Work from Start to Finish

Our team handles the generator-related electrical work and fuel connection with neat routing and a clean finish. The equipment stays accessible for future service, and the installation looks like it belongs at the home.

03

Support After the Work

Before we leave, we test the system and explain its normal operation in plain language. We also provide service support for the generators we install, so you know who to call when the system needs attention.

  • One-Team CoordinationElectrical work, fuel piping, and equipment setup stay under one roof.
  • Startup & Transfer TestingWe start the system, test transfer operation, and explain how it works.
  • 3-Year Workmanship GuaranteeCovered workmanship is backed in writing.

Generator Questions

Straight Answers Before You Install

How do you determine the right generator size for my home?

We review the equipment you want available and how much power it needs. Air conditioners, pumps, and other motors can draw extra power when they start. That information helps us match the generator and transfer equipment to your actual loads instead of relying on a generic size.

Should I choose whole-home backup or selected critical loads?

Whole-home backup can cover most or all of a home’s electrical loads when the generator and electrical service support it. Selected-load backup keeps the equipment that matters most available without powering every circuit. We help you compare the coverage you want with the capacity your home requires.

What does a transfer switch do?

A transfer switch keeps generator power separate from utility power. With an automatic standby system, it senses a utility outage and signals the generator to start. It moves the selected loads to generator power after the system is ready. When utility service returns, it transfers the loads back safely.

Can my Lyman home use natural gas for a standby generator?

Natural gas can be a good standby fuel when service and meter capacity meet the generator’s requirements. Greer CPW natural gas may serve parts of the area, but availability must be confirmed for your address. If natural gas is not suitable, we can discuss another approved fuel option that fits the equipment and property.

Where can a standby generator be installed?

A standby generator belongs outdoors in a location that meets the manufacturer’s instructions and applicable codes. It needs proper clearance from the home, openings, and other features. Service access also matters. We review your Lyman property before recommending a location.

Are permits and inspections required for generator installation?

Permit and inspection requirements depend on the property’s location and jurisdiction. For properties inside Town of Lyman limits, the town directs applicants to begin with Planning and Zoning. CC&I handles building permits and inspections. Properties outside town limits may follow the applicable Spartanburg County permitting process.

What happens after installation, and how does maintenance work?

After installation, we test the system to confirm its intended operation. We show you the basic controls and what to expect during an outage. The generator needs routine service and regular exercise according to manufacturer guidance and operating conditions.

Will Dave's provide service and repair support after installation?

We provide maintenance and repair support for systems we install. Keeping the unit accessible and following the recommended service schedule can help protect reliability. If a problem comes up, a technician can evaluate the system and recommend the appropriate repair.
