When You Need a Standby Generator
Jacksonville sits on the Atlantic coast and faces hurricane season every year from June through November. Tropical storms, lightning strikes, and grid overloads during summer heat waves can leave neighborhoods without power for hours or days. A standby generator eliminates the stress and discomfort of extended outages by keeping your air conditioning, refrigerator, lights, and security system running without interruption.
You need a standby generator if:
- You have experienced extended power outages during Jacksonville storms
- You rely on medical equipment that requires continuous power
- You work from home and cannot afford downtime
- You have a sump pump or live in a flood-prone area
- You want to protect your family during Florida's hurricane season
- You are tired of dealing with portable generators and extension cords
- You want to increase your home's value and appeal to buyers
An automatic standby generator is the most reliable form of backup power available for your Jacksonville home. Unlike portable generators that require manual setup and constant fuel management, a standby unit is permanently installed outside your home and activates automatically when the power goes out. Within seconds of detecting an outage, the generator starts and your automatic transfer switch routes power to your electrical panel. You do not need to be home, flip any switches, or run extension cords.
Our Standby Generator Installation Process

- Free on-site evaluation: We visit your home, assess your electrical load, inspect your panel, and recommend the right generator size
- Generator selection: Choose from Generac, Kohler, or Briggs & Stratton models based on your power needs and budget
- Permitting: We pull all required City of Jacksonville electrical and mechanical permits

Most standby generator installations are completed in one to two days once the permit is approved and the equipment arrives.
Choosing the Right Size Standby Generator
Selecting the correct generator size is one of the most important decisions in the process. An undersized unit will not keep up with your electrical demand, while an oversized generator wastes money on capacity you do not need. For most Jacksonville homes, the choice comes down to two options:
- Essential circuit coverage (10kW to 14kW): Powers your refrigerator, lights, a few outlets, Wi-Fi router, and one or two window AC units. This is a budget-friendly option that keeps the basics running.
- Whole home coverage (20kW to 26kW): Powers your entire electrical panel including central air conditioning, kitchen appliances, washer and dryer, and all lights and outlets. This is the preferred choice for most Jacksonville homeowners because losing AC in Florida's heat and humidity is not just uncomfortable, it can lead to mold growth and health risks.
Our electricians perform a detailed load calculation during the free evaluation to recommend the right size for your specific home. If you are planning future additions like an EV charger or pool equipment, we factor that into the sizing as well.
Standby Generator Fuel Options in Jacksonville
Standby generators in the Jacksonville area run on natural gas or liquid propane. If your home is connected to TECO Peoples Gas, a natural gas generator is usually the best option because the fuel supply is continuous and you never need to worry about refilling a tank during a multi-day outage. For homes without natural gas service, a propane generator with a dedicated tank provides dependable backup power. Our team helps you evaluate both fuel options and coordinates with licensed plumbers for the gas connection.
Standby Generator Cost in Jacksonville
Every standby generator installation is different, and the final cost depends on several factors specific to your home and property. These include the generator size and brand, fuel type, distance from the gas meter to the install location, electrical panel capacity, permit requirements, and any site preparation like concrete work or trenching.
Because of these variables, we provide a free on-site evaluation where we assess everything in person and give you a detailed written estimate with no surprises. This way you know exactly what you are paying for before any work begins.

Frequently Asked Questions
What is a standby generator and how does it work?
A standby generator is a permanently installed backup power system that sits outside your home and activates automatically when utility power is lost. It connects to your electrical panel through an automatic transfer switch that detects outages within seconds. The generator starts, powers your home, and shuts down when utility power returns. No manual intervention is needed.
How long does standby generator installation take?
Most installations in Jacksonville take one to two days once the permit is approved. Permit processing typically adds a few business days before the installation date.
Do standby generators need regular maintenance?
Yes. Annual maintenance includes oil and filter changes, spark plug inspection, battery testing, and coolant checks. Most units also run a weekly self-test cycle automatically to stay ready for the next outage.
Can a standby generator power my air conditioning?
Absolutely. A properly sized 20kW to 26kW standby generator can power your entire Jacksonville home including the central air conditioning system, which is essential during Florida's hot and humid summers.
