Failures We See on Standby Units
It did not start when the power went out
The most common culprits are a dead battery or a failed controller — both of which die quietly between outages while the unit looks perfectly fine sitting on its pad.
The weekly self-test stopped running
If you cannot remember the last time you heard the exercise cycle, that is the finding. A unit that skips self-tests has already told you it will not be there during the outage you bought it for.
Error codes or alarms on the controller
Low battery, failed sensor, fuel pressure fault, overcrank — the codes narrow it down, but the fix still needs someone qualified on both the fuel side and the electrical side.
It runs but the house never switches over
An engine that starts while the lights stay off points at the automatic transfer switch or the wiring between — a different repair from the unit itself, and one we handle in-house.
Why Standby Units Fail Quietly Here
Central Texas is hard on the parts of a generator you never look at:
Heat eats batteries
Long triple-digit summers shorten battery life well below the label, and the battery is the single most common reason a standby unit no-starts. It fails silently — no outage, no symptom, until the day both arrive at once.
The stakes are seasonal and steep
A summer outage puts a Central Texas house in the 90s within hours; a February event can mean frozen pipes. The time to find a dead unit is before the ERCOT alert, not during it.
Shifting clay stresses the fuel side
A pad that has settled on Blackland clay can strain the gas connection and cause pressure faults. Because we are licensed on the gas side, checking the fuel line is part of our diagnosis, not a referral.
How the Job Works
Full-system diagnosis
Battery and charger, controller, fuel pressure, sensors, and the transfer switch — we test the whole chain instead of swapping the first suspicious part.
Written repair price before work
You see what failed, why, and what the fix costs — approved by you before we touch a wrench. When age makes replacement a fair question, you get both numbers.
The repair, both sides of the unit
Batteries, controllers, and electrical faults on one side; fuel pressure, regulators, and gas connections on the other — one licensed crew covers both, so nothing gets handed off.
Test under load, then a schedule
We simulate an outage, verify the transfer and the self-test cycle, set a maintenance schedule so the failure does not repeat, and back the repair with a 1-year labor warranty.
What Moves a Repair Price
The number is set after diagnosis and approved in writing before work starts. What moves it:
Control side vs. fuel side
Batteries, chargers, and controller work generally price differently from fuel-pressure and gas-connection repairs, which carry testing requirements.
Parts and brand
Generac, Kohler, and Briggs & Stratton parts availability varies by model and age — discontinued components change the conversation.
Transfer switch scope
A fault at the automatic transfer switch instead of the unit itself is a different repair with different parts and testing.
You approve the price before any paid work starts. Diagnosis comes first, then written repair options — no surprise add-ons at the end of the visit.

Straight Answers, Before You Call
Why does my generator fail its weekly self-test?
Usually a weak battery, a charger fault, or a controller issue — the quiet failures. Sometimes it is fuel pressure, especially if the pad has shifted and stressed the gas line. The self-test is the unit asking for help early; ignoring it means finding out during a real outage.
The engine runs but the house stays dark. What is wrong?
That pattern points past the engine to the automatic transfer switch or the wiring between it and your panel. It is a genuinely different repair from a no-start, and it is why a repair visit tests the whole chain instead of stopping when the motor turns over.
Do you work on units you did not install?
Yes. Generac, Kohler, Briggs & Stratton, and most other standby lines. Bring us the model number when you book and we can usually arrive with the likely parts on the truck.
How do I know whether to repair it or give up on it?
Age, parts availability, and what failed. A battery or controller on an otherwise healthy unit is an easy repair call. Repeat fuel-system or engine problems on an older discontinued model often are not. When it is genuinely close, we put the repair number and the replacement number side by side and the decision stays yours.
