During an Outage

What Cannot Go Without PowerKeep Home Life Moving

Greenville outages can follow heavy wind, winter weather, or severe Upstate storms. Then the lights go out, the refrigerator stops cooling, and the systems your household relies on stop working.

Without power, the refrigerator stops cooling and rooms go dark. Most households want refrigeration, lights, phone charging, Wi-Fi, and a few outlets available so food and communication do not become another problem.

Medical equipment can lose power. Refrigerated medications can warm. When these needs are present, they belong on the list of loads the generator is sized to support.

Many heating and cooling systems need electricity to operate. A well pump does too. If they are not included in the backup system, the household can lose heat, air conditioning, or water during an outage.

An established home near the West End in Greenville and a newer house outside the city may put very different demands on standby power. The electrical service, cooling equipment, well pump, and daily routines all affect what should stay on. We build the backup plan around the household instead of forcing every property into the same package.

Standby Power for Your HomeBuilt Around What Matters

We size standby backup around the equipment your Greenville home needs during an outage, then match the electrical service, fuel supply, and property layout to that plan.

The RightFirst Standard

The RightFirst DifferenceOne Capable Team

At Dave's, we believe a generator installation comes out better when one capable team matches the loads and completes the electrical and fuel work. We keep the workmanship clean and stay with you after the install.

01

One team for the full installation

A standby generator crosses electrical, fuel, and equipment lines. We coordinate the work as one project, make sure each part fits the system, and give you one team responsible for the finished result.

02

Clean work that fits your home

We route wiring and fuel piping neatly, protect the home around the work, and leave the equipment accessible for future service. The installation should look deliberate and finished, not like an afterthought.

03

Follow-through after the install

We stay available after the install. You have the same team to call with system questions or when future service is needed. That makes the finished installation easier to live with over time.

  • Startup & Transfer TestingWe start the system, test transfer operation, and explain how it works.

Generator Questions

Straight Answers Before You Install

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

We list the equipment you want to run and calculate how much power it needs. We also account for motors and other equipment that use extra power when starting. That tells us which generator can carry the selected loads without overloading.

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

Critical-load backup covers selected circuits such as refrigeration, lighting, internet equipment, medical equipment, or a well pump where applicable. Whole-home backup can support much more of the home, but it requires enough generator capacity, electrical equipment, and fuel supply. We explain what each approach can realistically keep running.

What does an automatic transfer switch do?

When utility power fails, an automatic transfer switch moves the home to generator power. It keeps generator power separate from utility lines, which helps prevent dangerous backfeed. When utility service returns, it moves the home back to normal power. The switch must match the generator and backup setup.

Can my generator run on natural gas or propane?

Many standby generators use natural gas or propane. We verify whether natural gas is available at your address and whether the service can support the generator. If it cannot, propane may be the practical option. The selected loads and expected run time also affect fuel requirements.

Where can the generator be installed?

A standby generator must be installed outdoors with clearances required by its manufacturer and applicable codes. We evaluate access, utility connections, exterior layout, and the home’s appearance so the location works for the system and the property.

Will permits and inspections be needed for generator installation?

Generator installation can require electrical, gas, or other trade permits and inspections. The exact path depends on municipal jurisdiction and the work involved. The City of Greenville requires permits for regulated trade work, while applicable Greenville County properties follow the county process. We coordinate the required permit and inspection steps for our work.

What happens after installation, and does the generator need maintenance?

After installation, we test the automatic transfer function and show you how the system responds when utility power fails. Standby generators need regular exercise and maintenance under their manufacturer’s schedule. The service interval depends on the model, operating conditions, and use.

Can Dave’s help with generator service or repairs later?

Yes. We can inspect a standby generator and discuss service or repair options. What is possible depends on the make, condition, available parts, and the issue. Regular maintenance can reveal battery, oil, and operating concerns before an outage.
