Saint Augustine’s Most
Trusted
Generator
Installer

In Saint Augustine, whole home generator installation typically ranges from $7,000 to $20,000+ depending on generator size (11kW to 36kW+), fuel type (propane is most common in St. Johns County; natural gas via TECO Peoples Gas where available), and site specifics. Historic district addresses and coastal flood-zone properties along Anastasia Island require additional engineering for placement and elevation, which affects project cost. GenerX provides free in-home estimates with exact pricing—no surprises. Because we employ our own licensed electricians and gas fitters in-house rather than subcontracting, we offer competitive pricing without sacrificing quality.

Yes. Whole home generator installations in Saint Augustine require permits for the electrical work, gas line connection, and generator pad. Historic downtown addresses also require Historic Architectural Review Board (HARB) approval for any visible installation. The permitting authority depends on your address:

• City of Saint Augustine: City of Saint Augustine Building Department + HARB for historic district
• Unincorporated St. Johns County: St. Johns County Growth Management
• Saint Augustine Beach: City of Saint Augustine Beach Building Department
• Ponte Vedra, World Golf Village, Palencia, Nocatee: St. Johns County

GenerX handles all permit applications and inspections on your behalf, including HARB submissions for historic district properties.

From order placement, most Saint Augustine installations are completed within 30 to 60 days. The timeline includes permit approval from St. Johns County or the City of Saint Augustine, equipment delivery from one of our local facilities, site preparation, and professional installation. Historic district addresses requiring HARB review and coastal addresses on Anastasia Island requiring elevation engineering may add 1–3 weeks to the overall timeline.

For most Saint Augustine-area homes, a 22kW generator runs the entire house including air conditioning—critical during Florida summers and during the multi-day outages that follow major hurricanes like Matthew (2016). Smaller 11–14kW units power essential circuits. Larger 26–36kW units are ideal for homes over 4,000 sq ft, multi-HVAC estates in Marsh Landing, Palencia, or World Golf Village, or homes with heavy pool and outdoor loads. GenerX provides a free load assessment to determine the right size for your specific home.

No. GenerX employs its own licensed electricians, gas line specialists, and installation technicians in-house. We do not subcontract any part of your installation. This matters especially in Saint Augustine’s historic district, where workmanship quality is scrutinized by HARB and where subcontractor variability can compromise approvals. Every technician who touches your Saint Augustine project is a GenerX employee trained to our standards.

GenerX offers a 12-year warranty on installations—the longest in Florida. This covers both equipment and workmanship. We can offer this because of our financial stability, 20,000+ installation track record across Florida, and statewide service network with 8 warehouses and the largest service technician fleet in the state. No other dealer serving the Saint Augustine market can match this coverage.

Yes. GenerX is an authorized service provider for both Generac and Kohler generators. We serve Saint Augustine through our Florida statewide service network and regional parts inventory, providing annual maintenance plans, emergency repairs, and warranty service. During Atlantic hurricane season, our statewide fleet deploys to Northeast Florida to meet surge demand—critical coverage when Matthew-scale storms cause record flooding in St. Johns County and overwhelm local single-location dealers.

Most Saint Augustine-area HOAs allow whole home generator installations. Master-planned communities like World Golf Village, Palencia, Marsh Landing, Nocatee, and Sawgrass have architectural review committees that typically require: placement out of primary view from the street (usually side or rear yard), screening via enclosure or landscaping, and compliance with community noise ordinances (generally 55–65 decibels at the property line).

Historic downtown properties face a separate layer: the Historic Architectural Review Board (HARB) must approve any visible installation, and typically requires placement hidden from public view with period-appropriate screening. GenerX has experience submitting HARB applications and can advise on approvable placement before you commit. We can help you pick the best unit and make sure it is HOA compliant.

GenerX installs both natural gas and propane standby generators in Saint Augustine, and we are here to help you choose the right option for your home. Saint Augustine homes with natural gas service through TECO Peoples Gas, which serves portions of the City of Saint Augustine and select nearby areas, can connect directly to the utility line for unlimited runtime. Most St. Johns County addresses, including Palencia, World Golf Village, Nocatee, and Saint Augustine Beach, run on a propane tank, typically 500 to 1,000 gallons for several days of hurricane runtime. During your free GenerX estimate, we confirm what is available at your address and walk through both setups so you can pick the option that fits your lot, your budget, and your expected runtime.
