Florida Storms Don't Wait.
Neither Should You.
Northeast Florida averages more than a dozen named storms per hurricane season. When the power goes out — and it will — a whole-home standby generator keeps your family safe, your AC running, and your food from spoiling.
Double A has been installing and servicing generators across St. Johns, Flagler, and Duval County since 2003. As a Generac Authorized Dealer, we provide factory-backed warranties, certified installation, and lifetime service support.
What We Do
Complete Generator Services
From new installation to annual maintenance and emergency repair — we cover every aspect of generator ownership.
Standby Generator Installation
Whole-home and partial-home standby generator installation with automatic transfer switches. We install Generac, Kohler, and Briggs & Stratton systems sized precisely for your home or business.
Automatic Transfer Switch
An ATS detects an outage and starts your generator within seconds — automatically. No running outside in a storm. No manual switching. Just seamless, uninterrupted power.
Generator Maintenance
Annual tune-ups, oil changes, spark plug replacement, load testing, and battery checks. Preventive maintenance keeps your generator ready when a storm rolls in.
Generator Repair
Fast diagnosis and repair for all generator brands and models. We stock common parts to minimize downtime and get your backup power restored quickly.
Residential Generators
Protect your family, HVAC system, refrigerator, medical equipment, and home security systems. Never lose power during a Florida hurricane or tropical storm again.

What Customers Say
Real Reviews from Real Customers
“Double A installed a Generac 22kW whole-home generator for us before hurricane season. The installation was clean, professional, and permitted. When the next storm hit, we didn't lose a single appliance. Best investment we've made in this house.”
“My husband is on oxygen and we needed a reliable backup power solution. Double A walked us through the options, installed the right generator, and set up the automatic transfer switch. Peace of mind is priceless — I can't thank them enough.”
“Great experience from quote to installation. They handled the permit, the gas line connection, and the electrical hookup. Everything was done in one day. Highly recommend Double A for any generator work.”
“We got three quotes and Double A was the most thorough. They came out, assessed our panel, sized the generator correctly, and explained everything. The install crew was on time, clean, and professional. Five stars without hesitation.”
