Automatic standby generator systems sized, installed, fueled, wired, and tested the RightFirst way.
Dave’s handles the whole generator system, from the home load review and transfer switch plan to gas or propane coordination, electrical installation, startup testing, and clean workmanship. Backup power is not just a box in the yard.
The RightFirst way
A standby generator has to match the home, the fuel supply, the electrical system, and the transfer plan. If one piece is guessed at, the system can disappoint you when the outage finally hits. We size it, plan it, install it, test it, and stand behind the workmanship.

Service My GeneratorHow the install gets done
Whole home generator installation should feel organized from the first appointment to the startup test. We look at the home, the loads, the fuel setup, and the transfer plan before we recommend a system. No guessing. No slap-it-in-and-hope.
First appointment
We look at the home, the electrical loads, the fuel setup, and where the generator can be installed cleanly.
The system plan
We plan the generator size, natural gas or propane needs, automatic transfer switch, and electrical work before the install starts.
Install and verify
We install it clean, test the system, verify the transfer, and make sure the setup is ready before you need it.
No guessing. The generator, fuel supply, transfer switch, and startup test all matter when the outage finally hits.

What makes the system work
A standby generator is only as good as the plan behind it. The generator size, fuel supply, automatic transfer switch, and startup test all have to work together. That is where good installation separates itself from a box dropped in the yard.
The system has to match the way your home actually lives, not a rough guess based on square footage.
Natural gas or propane must deliver proper volume when the generator starts and the home is under load.
The transfer switch is the brain of the setup, routing emergency power when utility electricity drops out.
A standby system needs to be started, checked, and verified before the storm hits.

Backup power should feel automatic
When the utility grid goes down, your life should not stop. Heat, cooling, refrigeration, well pumps, and the essentials your home depends on stay live. The system just works because it was planned, installed, and tested before the storm hits.
Dave’s sizes it, installs it, tests it, and stands behind the workmanship.

Standby power is planned before the outage, not after it.
Generator brand options

Upstate generator planning
A standby generator install across Upstate SC is not one-size-fits-all. Some homes have natural gas. Some need propane planning. Some have larger HVAC loads, older electrical equipment, wells, septic systems, outbuildings, or long rural driveways. The right generator plan starts with the property in front of us.
That is why Dave’s looks at the whole setup before recommending equipment.
For homes with natural gas, the generator still has to match the available fuel supply. The meter, piping, existing appliances, and generator demand all matter before the system is installed.
Gas line planning →Many Upstate homes rely on propane, wells, septic systems, and longer outage planning. Tank size, regulator setup, runtime expectations, delivery access, and generator placement can all change the install plan.
Multiple HVAC systems, electric water heaters, older panels, detached garages, and service gear can change how the generator is sized and transferred. The electrical side has to be reviewed before the system is installed.
Main electrical panel planning →Who is doing the work
A whole-home generator is not a quick swap-out. It touches the electrical system, the fuel supply, the transfer switch, and the equipment your home depends on when the power goes out.
Dave’s is built around craftsmanship, communication, and accountability over chasing volume. Bigger is not always better. The work has to be planned, installed cleanly, tested, and stood behind.

Financing + Workmanship
A whole-home generator is a serious home upgrade. It touches the electrical system, fuel supply, transfer switch, and the equipment your home depends on during an outage. Financing can help you move forward without paying for the full project all at once, and Dave’s backs the workmanship with the same RightFirst standard we expect from our own team.
Generator installation is not just setting a unit outside and calling it done. The sizing, fuel supply, transfer switch, wiring, placement, startup, testing, and cleanup all matter. Dave’s looks at the whole system before recommending equipment, then installs it cleanly and verifies the setup before we call the job complete.
Clean Generator Installation: Placement, pad setup, electrical workmanship, transfer switch layout, gas or propane planning, access, and finish details all matter.
Startup Tested Before We Leave: We verify startup, operation, transfer function, load planning, and the setup details that matter before the next outage.
Accountability After the Job: If Dave’s puts its name on the installation, it should be work we are willing to stand behind.
Backup power does not have to be paid for all at once. Financing gives homeowners a way to plan a major generator project without waiting until the next outage makes the decision urgent.
The 3-Year Workmanship Guarantee is about the quality of the work Dave’s performs: the installation, connections, workmanship, startup testing, cleanup, and the install details we are responsible for.
It is not a claim that manufacturer equipment, storm damage, utility power, fuel supply, old electrical equipment, existing gas piping, or unrelated systems can never fail. We stand behind our workmanship.
Schedule a generator estimate and we will look at the home, the fuel source, the transfer plan, and the installation details before recommending equipment.

Generator FAQ
A standby generator is a major home system. These answers cover the basics, and the deeper sizing, brand, repair, and maintenance topics are handled in the generator child pages.
The right size depends on what you want to keep running during an outage. HVAC equipment, refrigeration, kitchen circuits, well pumps, medical equipment, internet, lighting, and other essentials all affect the plan. Dave’s looks at the home, the loads, the fuel source, and the transfer setup before recommending equipment. Learn more in our Sizing & Installation Guide.
Yes, some standby generators can be planned for whole home backup power, but the right answer depends on the home. Larger homes, multiple HVAC systems, electric water heaters, well pumps, and high-demand appliances may need careful sizing or load management so the system works the way you expect.
Most standby generators use natural gas or propane. Homes with natural gas need the meter, piping, and connected appliance load reviewed. Propane homes need tank size, regulator setup, delivery access, and expected runtime considered before installation. Read about our gas line planning services.
The automatic transfer switch watches utility power. When the grid goes down, it allows the generator system to start and transfer power to the circuits or panel setup it was designed to serve. That transfer setup is one of the most important parts of a standby generator installation.
The timeline depends on the generator size, fuel source, transfer switch setup, electrical layout, permitting, inspections, and site conditions. A simple install is different from a larger home with gas upgrades, panel work, load management, or more involved placement needs.

A standby generator that will not start may have a battery issue, maintenance issue, fuel issue, controller fault, transfer switch issue, or another system problem. Dave’s can troubleshoot generator problems and help determine whether the issue is maintenance, repair, fuel, electrical, or equipment related. Contact us for generator troubleshooting.
