Common Issues We Diagnose and Repair
Routine service and timely repairs are critical to the reliability and longevity of your standby generator. Each brand - whether Generac, Kohler, or another - has its own failure modes. Our technicians are trained to identify and correct these issues before they become full breakdowns. During every service visit, we go deep into the mechanical and electrical systems of your unit rather than stopping at a surface check.
- Battery failure: The single most common failure mode on standby generators. We test, clean, and replace batteries as needed.
- Low coolant levels: Liquid-cooled Generac and Kohler units can overheat when coolant runs low. We check, top off, and pressure-test cooling systems.
- Faulty transfer switch: A malfunctioning automatic transfer switch keeps your generator from taking over when the grid fails. We inspect, repair, or replace as required.
- Fuel line issues: Blocked, cracked, or contaminated fuel lines disrupt starting and running. We inspect gas and propane supply from meter to engine.
- Control board malfunctions: The control board is the brain of your generator. We diagnose communication errors, sensor faults, and firmware issues.
- Other issues we see regularly: oil leaks, corroded battery terminals, sensor faults, cooling or exhaust issues, clogged fuel filters, failing alternators, voltage regulators, and worn spark plugs.

Warranty Compliance and Cost Transparency
At GenCo, we work within your generator's manufacturer warranty to cover repairs and service calls wherever possible. As a Generac Premier Dealer and Authorized Kohler Installer, we have direct warranty authority that most electricians do not. Before we perform any non-warranty work, our service team reviews the scope with you and provides a clear breakdown of any added cost. You make informed decisions - no surprises on the invoice.
Why Service and Repairs Matter Along the Atlantic Coast
The Atlantic Coast - including Northeast Florida and Southeast Georgia - is defined by seasonal weather changes and severe storms, especially during hurricane season. Regular service and timely repairs make sure your standby generator is ready to perform when you need it most.
- Readiness for hurricane season: A generator that has not run in a year is not a dependable generator. We verify storm-ready status well before the first named storm.
- Preventative maintenance: Regular service catches small problems before they become expensive repairs. Ask about our maintenance plans.
- Longevity of your investment: Routine service and timely repairs extend the usable life of your generator by years.
- Energy security: A well-maintained unit delivers the peace of mind you bought it for - your home or business stays powered.
- Compliance with safety standards: Regular servicing keeps your generator performing within manufacturer and code specifications, reducing the risk of unsafe conditions.
