Generator Service & Repair in Dalworthington Gardens

We service and repair standby generators and the transfer switches that connect them to your home. One small crew diagnoses the fault, explains it, fixes it and tests the unit under real load, so it starts when the power goes out.

Keeping a standby generator ready to start

A standby generator can sit for months, then has to carry your home within seconds of an outage. Most failures we find come from that long wait. Common causes are a weak starting battery, old oil, a fouled spark plug, or a transfer switch that has never been tested with the house on it. Our service covers the generator, the automatic transfer switch and the wiring between them.

The same people stay on your visit from first look to final test. The electrician who reads the controller history is the one who replaces the part and watches the unit run afterward. Our electricians are licensed and insured, and the work is done under a Master Electrical License.

Sometimes a unit is not worth another repair. When that is the case, we tell you plainly and can talk through generator installation or home battery backup systems as the next step.

What our generator visit includes

Starting battery and charger
A weak battery stops more generators than anything else. We put the battery under a load test, clean and snug the terminals, and check that the trickle charger keeps it at proper voltage.
Engine maintenance
Oil and filter, spark plugs and air filter are changed or checked against the manufacturer's schedule. On liquid-cooled units we also look at coolant, belts and hoses.
Transfer switch inspection
We check the contacts and the torque on the lugs and look for heat discoloration. Then we simulate an outage to confirm the switch moves your home to generator power and back again cleanly.
Controller and settings
We read the event log and any stored fault codes, then confirm the weekly exercise schedule and settings are correct.
Enclosure and connections
We clear out insect and rodent nests, check for chewed or corroded wiring and look over the conduit and clearances around the pad.
Repairs and parts
When something has failed, such as a starter, voltage regulator, breaker or control board, we price the repair in writing before we replace it.

When to have your generator looked at

  • The scheduled test run has gone quiet

    Your generator is set to start itself for a few minutes on a routine, usually once a week. When that routine stops and the yard stays silent, the unit has a fault or has lost its settings.

  • Warning lights on the control panel

    A yellow or red light on the panel is the controller logging a problem. Some faults put the unit into lockout, which means it will not start when the power fails.

  • Hard starts or uneven running

    Long cranking before the engine catches, speed that rises and falls, or lights that flicker while the generator powers the house usually trace back to fuel, ignition or the voltage regulator.

  • Stuck on generator after the grid returns

    The switch should hand your home back to utility power once the outage ends. If it lingers on the generator, or never picked up the load at all, the switch or its control wiring is where we start.

  • Heavy use or a missed annual service

    A long outage after a summer storm or a hard freeze can put enough hours on the engine to bring oil and filters due early. If a year has passed since anyone serviced it, it is due regardless.

How a service visit runs

  1. 1

    Book by phone

    Tell us the make, model and what you have noticed. That lets us set aside the right time and bring the parts most likely to be needed.

  2. 2

    Look before we change anything

    We read the controller history, test the battery and go over the enclosure and transfer switch. We want the cause first, not a pile of replaced parts.

  3. 3

    Explain and agree

    You get photos of what we found and a written, line-item price for any repair. Nothing beyond routine maintenance happens until you approve it.

  4. 4

    Repair, test and tidy up

    After the work, we simulate an outage and let the generator carry your home while we watch voltage and frequency. Then we reset the exercise schedule, clear the area and leave you notes on what was done.

What moves the cost of generator service

Routine maintenance and a repair are priced differently, and we keep them separate on your estimate. You get a written price before any repair work begins, so you know what you are approving.

Unit type and size
Liquid-cooled generators have more fluids, belts and service items than air-cooled units, so their maintenance takes longer.
Which parts have failed
A battery or spark plugs is a small job. A control board or voltage regulator costs more, and some brands only sell those parts through their own suppliers.
Maintenance history
A unit that has gone several years without service often needs more than one fix at once, such as old oil, a worn battery and corroded terminals.
Transfer switch condition
Loose lugs or pitted contacts in the switch add time and parts to the visit, and we price that work separately from the generator itself.

Generator service questions

Something not covered here? (682) 327-0474

How often does a standby generator need maintenance?

Once a year is the usual interval, or sooner if the unit has logged a lot of run hours. The exact schedule for your model is in the owner's manual. Many people book it in spring so the unit is ready before the stormy months.

Can you work on my brand of generator?

We service common residential standby generators, both air-cooled and liquid-cooled. Tell us the make and model when you call. We'll tell you honestly whether it is one we can work on, and we'll bring the likely parts.

My generator runs, but the house has no power. What's wrong?

That usually points to the transfer switch, a tripped or failed breaker on the generator, or the control wiring between the two. We test each one in order until we find the fault, then show you what failed.

What if the problem is the gas supply?

We check what we can at the unit, including whether it is getting enough fuel to run under load. Work on the gas line itself belongs to a plumber or your gas utility. If that is where the problem is, we'll tell you so and note what we measured.

Is the repair covered after you leave?

Our repair work carries a 1-year workmanship warranty. Parts come with the manufacturer's own coverage, and we hand you any paperwork that comes with them.
