Generator Repair & 24/7 Emergency Service
If your generator won’t start, shows a fault code, shuts down under load or fails to transfer power, call (256) 938-4971 any time, day or night. We diagnose and repair standby generators from all major brands , including battery, fuel, ignition, controller and transfer switch problems. See our generator repair services.
Portable Generator Repair & Tune-Ups
Own a portable generator? We repair and tune up portable units too, including hard starting, surging, low power output and fuel-system problems caused by stale gasoline. A pre-season tune-up means it starts when the next storm hits. For a safe connection to your home without backfeeding utility lines, ask about a transfer switch or interlock kit.
Generator Maintenance in Decatur, AL: What’s Included
A standby generator sits idle most of the year, then has to start instantly in the worst weather. Annual maintenance is what makes that start reliable. Our generator maintenance visit includes
- Oil and oil filter change
- Air filter and spark plug inspection or replacement
- Battery load test, terminal cleaning and replacement when weak (a worn battery is one of the most common reasons a generator fails to start)
- Coolant and hose check on liquid-cooled units
- Natural gas or propane line, regulator and connection inspection
- Automatic transfer switch test
- Controller check for fault codes and exercise-cycle settings
- Clearing debris, vegetation and insect nests from the enclosure (fire ants often nest inside generator housings in Alabama)
How Often Should a Generator Be Serviced?
Most manufacturers recommend professional maintenance at least once a year, and sooner after a long outage with heavy run time; your owner’s manual lists the run-hour interval. For Decatur homes, late winter is the best time, before spring storm season. Between visits, your generator should run a short self-test every week or two. If it stops exercising or shows a warning light, call us. Portable generators need a tune-up once a year and a short test run every month or so, with fresh or stabilized fuel.
Why Decatur Homeowners Invest in a Generator
There are several compelling reasons to get a generator, especially if you live in an area prone to power outages like North Alabama, where spring tornado season, summer thunderstorms and occasional winter ice storms can knock out power for hours or days.
- Backup Power During Outages: Keep essential systems running: keep your air conditioner running through humid Decatur summers, plus your heat pump or furnace, refrigerator, freezer, sump pump and well pump. A standby generator with an automatic transfer switch restores power within seconds, even when you’re away.
- Business Continuity: Business continuity: for Decatur shops, offices and restaurants, a generator prevents lost sales, spoiled inventory and downtime during outages.
- Protecting Sensitive Equipment: Work from home and home security: keep internet, computers, security systems and garage doors working when the grid is down.
- Emergency Preparedness: Storm readiness and peace of mind: a generator that starts on its own means no refueling or extension cords in the middle of a storm, and no returning to a warm freezer or a flooded basement.
- Medical Requirements: If someone in your home relies on oxygen concentrators, CPAP machines or other powered medical equipment, a generator keeps it running automatically during an outage.

Standby vs. Portable Generators: Choosing Backup Power
Most Decatur homeowners choose between a permanently installed standby generator and a portable unit. Here is how they compare:
| Home standby (whole-home) generator | Portable generator | |
| How it starts | Automatically, through an automatic transfer switch, within seconds of an outage | Manually; you start it and connect it |
| Fuel | Natural gas (from Decatur Utilities, where available) or propane | Gasoline; some models are dual-fuel |
| What it powers | The whole home or selected essential circuits, including central AC | A few appliances or circuits |
| Connection | Permanently wired to your electrical panel | Cords, or a transfer switch or interlock kit installed by an electrician |
| Upkeep | Weekly self-test plus annual professional maintenance | Owner maintenance and regular test runs |
Whichever you own, we service both: whole-house standby systems and portable generators, from no-start problems to pre-season tune-ups.
Considering the different types of generators, their cost, and the maintenance requirements of each is important when deciding which generator is best for your home. Our licensed electricians can help you choose the generator that meets your needs.
