Generator Service & Repair in Forest Hill
A generator that sits idle for months can quit on the very night the power goes out. We maintain and fix home generators and the transfer switches they run through, test them under load, and tell you in plain terms what needs work now and what can hold off.
Backup Power Only Helps If It Starts
Most generator failures we see are small things left too long. A weak battery. Old oil. A wasp nest in the air intake. A transfer switch that hasn't moved in two years. None of it shows up until the power drops.
We'd rather find those problems on a calm afternoon than during an outage. A scheduled service visit gives you time to budget for any parts, plan the repair, and know the unit will carry your home when the grid goes down.
We work on permanently installed standby units and on the inlet and interlock setups used with portable generators. If your unit is past saving, we'll say so and walk you through Generator Installation or Home Battery Backup Systems as options.
What We Do on a Service Visit
Oil, filters and spark plugs
We swap the oil and oil filter, look at the air filter and replace it if needed, and check the spark plugs. This is where engine wear begins, so it's the heart of regular maintenance.
Battery testing
A dead battery is the top reason standby units fail to start. We put the battery under a load test, clean its terminals and make sure the charger keeping it full is working.
Transfer switch test
We do an actual transfer, shifting your home's load onto the generator and back again, and watch for burned contacts, loose lugs and sluggish switching.
Running under load
We let the unit carry load long enough to confirm steady voltage and frequency, and we record the readings so next year's numbers have something to be checked against.
Controller and fault history
We pull the controller's history, clear stale faults and make sure the weekly exercise run is scheduled and really happening.
Enclosure and fuel hookup
We clean out debris and nests, look over the fuel connection at the unit for wear or leaks, and check coolant on liquid-cooled units. If the gas supply line needs attention, we let you know who handles it.
Signs Your Generator Needs Service
The weekly test run went quiet
Most standby units start up on their own once a week for a few minutes. If you haven't heard that hum lately, a dead battery or a controller setting may be holding it back.
A light is on at the controller
Red or amber on the display means the unit has recorded a fault. Depending on what it logged, the generator may lock itself out and sit still during the next outage.
Long cranking or a rough idle
If it turns over for a long time before catching, surges up and down, or puffs dark smoke, the cause is usually fuel, spark plugs or the battery.
Lights flicker on backup power
Unsteady power during an outage can mean the generator is carrying too much or the voltage regulator is wearing out. That is hard on electronics and motors in your home.
It's been over a year
Hot Texas summers are hard on batteries and oil, even on a unit that barely runs. If you can't remember the last service, it's due.
How the Visit Goes
- 1
You call, we schedule
Tell us the make, the size if you know it, and what you've noticed. We set a time that works and come prepared with the usual maintenance parts.
- 2
Look before we touch
We read the controller, check the battery and look over the unit and switch before changing anything. That tells us whether this is a tune-up or a repair.
- 3
Service and testing
Routine work gets done on the spot. Then we run a transfer and a load test with your home on generator power for a short stretch, and we tell you before we cut over.
- 4
Plain findings and next steps
You get a written list of what we did, what we found, and what we'd recommend. Anything that can wait gets a rough time frame so you can plan for it.
What Moves the Price
A routine service on a unit in good shape is the simplest visit. Repairs depend on what failed and whether the parts are easy to get. We give you the price for the work before we start, and if we find more than expected, we stop and talk it over first.
- Type and size of unit
- Air-cooled units are simpler to service. Larger liquid-cooled models take more oil, coolant and time.
- Parts needed
- A battery or plug set is a small add. A controller board, regulator or starter costs more and may need to be ordered.
- Age and parts availability
- Older or discontinued models can be harder to source parts for. Sometimes that changes whether repair still makes sense.
- Transfer switch work
- Replacing contacts, tightening lugs or swapping a failed switch adds labor inside your electrical system.
- Access to the unit
- Tight side yards, fencing or overgrown landscaping can add time to the visit.
Questions About Generator Service

How often does a standby generator need service?
For most homes, a yearly visit is a sound starting point. If the unit put in long hours during an outage, get it checked after that as well. Spring works well, ahead of the summer heat and storms.
Will you service a generator someone else installed?
Yes, whoever put it in. If we find a problem with the original install, such as an undersized wire or no interlock, we'll point it out and explain what the fix would take.
Who works on the generator?
The work is done by our licensed and insured electricians. That's important, since a generator connects straight into your panel and transfer switch and is more than an engine sitting in the yard.
Do you look at portable generator hookups?
We check the inlet box, the interlock or transfer switch and the cord connections that feed portable power into the house. Engine work on small portables is a job for a small engine shop, and we'll let you know if that's where yours should go.
Should I fix an older generator or replace it?
It can go either way. In our five years in business, we've found the answer mostly depends on parts and engine hours. We'll give you a straight recommendation and explain why.
Get Your Generator Checked Before You Need It
Pick a time that suits you, and we'll test the whole system and tell you where it stands. No rush, no surprises when the next outage comes.
