Generator Service & Repair in White Settlement
We service and repair standby and portable generators, from weak batteries and stuck transfer switches to engines that crank but won't catch. You get a clear diagnosis and a repair done to code. Then we check in once the next exercise cycle has run to confirm the fix held.
Keeping a backup generator ready to carry your home
A standby generator spends most of its life sitting still, and that is where trouble starts. Batteries sulfate, oil breaks down, spark plugs foul during short weekly exercise runs, and insects move into a warm enclosure. None of it shows until the utility drops and the unit tries to pick up your home's load.
Our generator service and repair covers the engine and controller, plus the electrical side many mechanics skip: the automatic transfer switch, the breakers feeding it and the connections at your panel. For portable units, we check the inlet box, the interlock kit and the cord that tie the generator to your home.
When the work is done, we don't just latch the enclosure and leave. We follow up once the next scheduled exercise run has happened, walk you through the status lights and fault history, and explain what to watch between visits.
What a generator service visit covers
- 01
Battery and charger testing
We load-test the starting battery instead of only reading its voltage, because a battery can show 12.6 volts and still collapse when the starter pulls. We also confirm the built-in charger is actually charging. A Texas summer inside a metal enclosure can take out a battery well before its date code suggests.
- 02
Engine tune-up
Oil and filter, air filter and spark plugs, gapped to the manufacturer's spec. On liquid-cooled units we check coolant condition and hoses. On air-cooled units we clear the cooling fins and intake screens so the engine doesn't overheat under load.
- 03
Transfer switch inspection
We confirm the automatic transfer switch senses the utility loss, signals the start, transfers cleanly and retransfers when power returns. We look for pitted contacts, loose lugs and heat discoloration on the terminals.
- 04
Fuel supply check
For natural gas and propane units, we inspect the regulator, flexible fuel line and sediment trap. A restricted supply can let a generator start fine and then stall when the air conditioner kicks on. If the gas piping itself needs changes, we tell you plainly so a plumber can handle it.
- 05
Controller and fault history
We read the event log, fix the cause before clearing old faults, and confirm the clock and exercise schedule are set correctly so the weekly run happens when you expect it.

A red light or fault code
Common codes include low battery, overcrank, low oil pressure and overspeed. Each points to a different cause, so clearing the code without fixing the problem usually brings it right back.
The weekly exercise stopped
If you no longer hear the generator run on its scheduled day, the controller may be in off mode, the battery may be too weak, or the clock may have reset during an outage.
Hard starting or surging
Long cranking, rough running or engine speed that hunts up and down usually means fouled plugs, a clogged air filter or a fuel pressure problem.
Power doesn't reach the house
If the generator runs but your home stays dark, or lights dim hard every time the compressor starts, the fault is likely in the transfer switch or the load the unit is being asked to carry.
Ants or nests in the enclosure
Fire ants are drawn to energized contacts and can pack a relay or terminal block until it fails. Mud daubers and mice chew wiring and block air intakes the same way.
How a generator repair visit runs
- 1
Review symptoms and history
We ask what you've seen and pull the controller's event log before touching anything. The log shows whether the failure happened during exercise, during an outage or at transfer.
- 2
Isolate and test
We set the controller to off, disconnect the battery before working near moving parts, and test components one at a time: battery, starter, ignition, fuel, sensors and transfer switch. You hear what failed and why before we replace anything.
- 3
Repair and run under real load
With your approval we make the repair. Then we simulate an outage by opening the utility disconnect so the generator starts, transfers, carries your home and retransfers while we watch voltage and frequency at each stage.
- 4
Walkthrough and care notes
We show you the status lights, how to check the exercise schedule and what to keep clear around the enclosure, and leave written notes on what we serviced.
- 5
Check back after the next exercise
A week or two later we follow up to confirm the unit ran its scheduled exercise with no new faults. If something changed, we set a time to come look at it.
What affects the cost of generator service
We price the work once we've seen the unit and found the cause, and we explain the repair before we start. Routine maintenance and a single worn part cost far less than a controller board or transfer switch replacement. These are the things that move the number.
- Generator type and size
- Liquid-cooled units have more fluids, belts and hoses to service than air-cooled ones, and larger engines take more oil and parts.
- Which parts failed
- A battery or set of plugs is a small repair. A starter, voltage regulator or control board is a larger one.
- Age and parts availability
- Older units sometimes need discontinued parts. When a repair no longer makes sense, we say so and walk you through generator installation as the alternative.
- Access and enclosure condition
- Tight placement against a wall, corrosion or pest damage inside the housing add time to the visit.
- Related work we find
- Loose lugs in the panel or missing surge protection are listed separately so you can decide. Surge protection and torque and cleans are often done on the same visit.
Generator service questions
How often should a standby generator be serviced?
Most manufacturers call for maintenance once a year or at a set number of run hours, whichever comes first. A long outage piles up hours quickly, so the unit may need service sooner. We read the hour meter and tell you where you stand on the schedule.
Can you work on a generator someone else installed?
Yes. We service standby units and portable generator connections regardless of who installed them. While we're there, we look at the transfer switch wiring and bonding too, and if something isn't to code we explain what it is and why it matters.
Why does my generator pass its weekly test but fail in a real outage?
Most exercise runs happen with no load, so they only prove the engine starts. A weak battery, a fuel supply that can't keep up or a transfer switch fault can hide until your home's load arrives. That's why we test with your circuits actually transferred.
What should I do between service visits?
Keep plants, mulch and stored items away from the enclosure vents, and glance at the status light once a month. Listen for the weekly exercise on its scheduled day. When a long outage ends, give us a call so we can check oil level and battery condition.
Should I repair or replace an older generator?
If the engine is sound and parts are available, repair usually makes sense. If the controller is obsolete or the engine is worn and burning oil, repeated repairs add up. We give you a straight answer with the reasons behind it.
Get your generator ready before the next outage
Tell us what your generator is doing, or not doing, and we'll set up a service visit to find the cause. Once the repair is done, we check back to make sure it keeps running on schedule.
