FAQs
Why do homeowners and businesses in Graysville need a standby backup generator?
Graysville experiences severe thunderstorms, occasional tornado activity, and grid outages caused by aging infrastructure. A standby generator automatically powers your essential circuits—lights, HVAC, refrigerators, medical devices, computer servers—within seconds of a blackout, preventing safety risks, costly downtime, and property damage associated with spoiled food, frozen pipes, or lost data.
What size generator do I need for my property?
Proper sizing depends on the total running and starting wattage of the equipment you want to support. A typical 2,500–3,000 sq ft home in Graysville usually requires a 14–22 kW air-cooled unit to cover critical loads. Larger homes with multiple HVAC systems or commercial sites may need 30 kW–150 kW liquid-cooled models. We perform a free on-site load analysis, calculate surge currents, and recommend a generator that balances capacity, efficiency, and budget.
How often should my generator be serviced, and what does maintenance include?
Standby generators should receive preventive maintenance every 6–12 months or after 200 hours of run time—whichever comes first. Service includes oil and filter changes, spark plug replacement, air-filter cleaning, battery inspection, coolant checks (for liquid-cooled units), fuel system examination, software/firmware updates, and full operational testing under load. Regular maintenance ensures warranty compliance and maximizes the generator’s 20-30 year life expectancy.
What fuel options are available and which is best for Graysville?
Most residential units run on natural gas or propane (LP), while larger commercial systems may use diesel. Natural gas is the most convenient in Graysville where municipal lines are available; it offers continuous supply and cleaner emissions. Propane is ideal for rural areas without gas mains, providing long shelf life and easier storage than diesel. Diesel delivers higher power density and is preferable for mission-critical or off-grid applications but requires on-site tank compliance and winter additives.
How quickly will the generator start when the power goes out?
Our automatic transfer switch (ATS) senses utility loss in less than one second and signals the generator to start. The generator reaches operating speed and voltage in 5–10 seconds, after which the ATS transfers your electrical load. You experience a brief, 10-15 second interruption versus several minutes—or hours—of darkness with portable units.
Are permits required in Graysville for installing a standby generator, and do you handle them?
Yes. Walker County and the City of Graysville require electrical and, if applicable, gas plumbing permits. Systems over 15 kW may also need zoning approval for noise and setback compliance. Our turnkey service includes permit applications, site drawings, utility coordination, code-compliant concrete pad installation, and post-installation inspection scheduling, so you don’t have to navigate the process yourself.
