Keep Your Generator Running at Peak Performance

A reliable generator is only as dependable as the maintenance behind it. Whether you're protecting your home from unexpected outages or powering a critical commercial operation, regular generator maintenance ensures your system is always ready to perform.

Why Generator Maintenance Is Essential

Over time, generators are subject to wear and tear—oil degrades, batteries weaken, and internal components can corrode. Without scheduled maintenance, even high-end models are at risk of failure when you need them most. Our expert technicians provide thorough inspections, diagnostics, and tune-ups designed to keep your unit running efficiently and safely year-round.

Storm-Ready install package

$2,000 off a generator install. While supplies last.

It only comes off the units on our floor, so when they're gone, it's gone. New air-cooled Generac installs come with a free 10-year warranty, and financing is there if you want it. Permit timing depends on your city or county. The install itself is usually one day.

Maintenance plans: once a year is what we recommend

We recommend a full maintenance service once a year. Our Shield Protection plans are twelve-month plans sized to your generator, and every level includes 24/7 remote monitoring. Call (713) 467-1125 for plan pricing.

01

Silver: the yearly plan we recommend

Silver includes one annual maintenance service, 24/7 remote monitoring and a free home electrical and generator safety inspection. For most homes that is the right fit: the generator gets a full service every year, and if it reports a problem between visits, we see it on the monitoring side before you need it in an outage.

02

Bronze: monitoring, maintenance as you go

Bronze gives you 24/7 remote monitoring and pay-as-you-go maintenance. It suits owners who want us watching the generator but prefer to book and pay for each service visit when it is due. We still recommend scheduling that service once a year so the oil, filters, battery and transfer switch get checked.

03

Gold: two services a year plus a load test

Gold adds a second maintenance visit, so the generator is serviced every six months, plus a yearly load test and the free safety inspection. It makes sense for generators that run often, homes with medical equipment, or owners who simply want a second check before storm season and before winter.

04

Platinum: maintenance as needed and storm priority

Platinum covers maintenance as needed, a yearly load test, first-call storm priority, a 48-hour service guarantee, 10 percent off electrical services and the free safety inspection. It is built for owners who want the generator handled completely. See the Shield Protection page for the full plan details by generator size.

Why Standby Generators in Houston Need Regular Maintenance

A standby generator can sit quietly for months and still wear out. Houston weather makes that worse, not better.

01

A generator that sits still is still aging

Oil breaks down over time even when the engine barely runs. Batteries lose strength sitting in a hot enclosure. Rubber hoses, belts and seals dry out and crack. Wiring connections loosen with heat cycles. None of that shows up until the unit is asked to run for days in a row, which is exactly when you need it most.

02

Heat, humidity and storms are hard on equipment

Houston summers bake the enclosure, and humidity works its way into connections and control boards. Storms push debris, standing water and wet leaves around the base of the unit. A generator near the coast or by a sprinkler head sees even more corrosion. Annual generator maintenance is how we catch that wear while it is still small.

03

The weekly exercise is not maintenance

Most standby generators run a short self test every week. That exercise keeps the engine lubricated and confirms it can start. It does not change the oil, test the battery under load, check the valve clearance or confirm the transfer switch moves the house over. A unit can pass its weekly test and still fail in the first hours of a real outage.

04

Long outages add up fast

During a big storm, a standby generator can run around the clock for days. That puts more hours on the engine in one week than it sees in normal weekly tests for a long time. After an extended outage, the oil, filters and spark plugs may be due no matter when the last visit was. Call us once the grid is back and we will check it.

Generac Maintenance Schedule and Annual Generator Service

Generac, like every standby manufacturer, publishes a maintenance schedule in the owner's manual. We follow it for your model.

01

How the Generac maintenance schedule works

Generac sets service intervals by run hours and by time, whichever comes first. For most homes that weekly testing is light, so the time limit comes first and the unit is serviced once a year. Homes that run the generator a lot during storms may reach the hours limit sooner. The model number on the data label tells us which schedule applies.

02

Air-cooled and liquid-cooled units

Most home standby generators are air-cooled, and their service centers on oil, filters, spark plugs, the battery and valve checks. Larger liquid-cooled units add coolant, hoses, belts and a radiator to the list. The visit takes longer and has more parts to inspect. We tell you which type you have and what that means for its upkeep.

03

The maintenance reminder on the controller

Many Generac controllers show a maintenance reminder or alert when service is due by the clock or by hours. It is a reminder, not a failure. The unit will still run, but it is telling you it is time. We service the unit and reset the reminder as part of the visit.

04

Why storm season timing matters

The best time for generator annual maintenance is before hurricane season, when there is time to order a part and fix it calmly. Once a storm is in the forecast, every technician in Houston is busy. Planning your yearly service in the spring keeps your unit ready and keeps you off the waiting list.

What You Can Do Between Service Visits

Owners do not need tools to help a generator stay healthy. A few look-only habits catch problems early.

01

Keep the area around the unit clear

Leave clear space around the enclosure for airflow and service access. Trim shrubs, keep mulch and leaves away from the base and do not stack anything against it. Watch for fire ant mounds, wasp nests and rodent signs near the unit, because they move inside and chew or short wiring. Never spray water or chemicals into the enclosure.

02

Watch the weekly exercise and status lights

Know what day and time your generator exercises, and listen for it now and then. Check that the controller is in AUTO and that the status light shows ready. If it shows a warning, missed its test or sounds different, write down what you saw and call us. A note now often prevents a repair later.

03

Use Mobile Link if you have it

Generac Mobile Link lets you see the generator's status, exercise history and alerts on your phone. Many owners hear about a problem from the app before the unit is ever needed. If you share access with us as your servicing dealer, we can see faults too. Ask us about setting it up on an existing unit.

04

Keep propane topped up

If your generator runs on propane, keep an eye on the tank level, especially before storm season. A low tank is one of the most common reasons a generator stops during a long outage. Natural gas units do not need refilling, but tell us if the gas company has changed your meter, because supply changes can affect how the unit runs.

Generator Won't Start: How Maintenance Prevents It

Most failures we see during outages trace back to something a maintenance visit would have caught. If your generator will not start right now, our generator repair page walks through the safe checks.

01

Battery testing and replacement on schedule

A weak battery is the top reason a standby generator will not start. Batteries age in the heat whether the generator runs or not. During maintenance we load test the battery and check the charger, so a tired battery gets replaced on a sunny day instead of failing during a storm.

02

Oil level, oil condition and low oil shutdowns

The controller shuts the engine down to protect it when the oil is low. Old oil also gets thinner and less protective in the heat. Fresh oil and a full level at every service keep the engine from tripping a low oil alarm in the middle of an outage. We also look for leaks that would drop the level between visits.

03

Pests, debris and wiring

Rodents and insects like the shelter of a generator enclosure. They nest in it, chew wire insulation and block air intakes. During a maintenance visit we open the enclosure, clear out debris and look over the wiring and connectors. Finding a chewed wire during maintenance is a small fix. Finding it during a hurricane is a long night.

04

Spark plugs, air filter and fuel connections

Worn spark plugs and a dirty air filter make an engine hard to start and rough under load. Fuel line connections can loosen or corrode. Each of these is checked during the annual service and replaced when it is due, which keeps hard starts from turning into no starts. We also look for signs that the engine has been running rough, such as soot or oil residue, which can point to a problem worth fixing early.

Generator Maintenance for Every Brand and Every Install

You do not need to have bought your generator from us to have us maintain it.

01

Generac maintenance from a Prestige Dealer

Wired is a Generac Prestige Dealer. We use Generac parts and follow the factory maintenance schedule for your model. That matters for performance, and it gives you a clear service record if you ever need to show one to a warranty provider.

02

Kohler, Briggs and Stratton and other brands

We maintain Kohler, Briggs and Stratton, Champion and other standby generators too. The basics are the same from brand to brand: oil, filters, battery, ignition, fuel supply, controller and transfer switch. Tell us the brand and model number when you call, and we bring what the unit needs. Each manufacturer has its own schedule and parts, and we follow the one for your unit.

03

Units that were installed by someone else

If your generator came with the house or was installed by a company that is no longer around, the first visit is a catch-up. We check the condition of the unit, the pad, the gas line and the transfer switch, and we tell you what is overdue. From there it goes on a normal yearly schedule.

04

Shield Protection plans

If you would rather not track service dates, a Shield Protection plan puts the visit on our calendar for you. Plans include monitoring and storm priority. See the Shield Protection page for what each plan covers, or ask us when you call. A plan also means someone else remembers when the battery is getting old or when a part was flagged at the last visit. It is the easiest way to make sure maintenance actually happens every year.

Commercial and Diesel Generator Maintenance

Businesses depend on their generators in a different way, and larger units need a deeper service.

01

Commercial standby generators

Offices, clinics, churches, restaurants and small facilities often run larger liquid-cooled generators with bigger transfer switches. Downtime costs money, and some sites need records for an inspector, a landlord or an insurer. We schedule maintenance around business hours. Larger units may also need service more than once a year, depending on run hours and how critical the load is. We set a schedule that matches the site and the manufacturer's guidance.

02

Diesel generator maintenance

Diesel units need more than an oil change. Fuel stored in a tank ages and can grow algae or collect water, which clogs filters and hurts injectors. Coolant, belts and block heaters also need attention. We check fuel condition, change fuel and oil filters and inspect the cooling system as part of a diesel service.

03

Load testing and transfer testing

A generator that only runs with no load is not proven ready. For commercial sites, a transfer test with your approval confirms the generator carries the building and the switch moves back to utility power properly. We schedule it with you so the brief power interruption does not catch anyone off guard.

Generac Maintenance Plan or One-Time Service: How to Choose

You can book a single service visit whenever you need one, or put the generator on a plan so it gets done without you thinking about it. Both work. Here is how they compare.

01

A one-time annual service visit

A single visit suits owners who like to schedule things themselves. You call, we book a technician, and the generator gets the full service on the checklist above. The catch is remembering. Many generators that fail during an outage were simply never serviced after the first year. If you go this route, put a reminder on your calendar for before storm season every year.

02

A Shield Protection maintenance plan

A Shield Protection plan takes the remembering off your plate. Service is scheduled for you on the interval your plan covers, the generator can report to us through remote monitoring, and plan customers get storm priority when the Gulf gets busy. For most Houston homes, the yearly plan we recommend is the simplest way to keep a generator ready without tracking it yourself.

03

Who each option fits

A plan fits families who rely on the generator for medical equipment, people who travel or own a second home, and anyone who knows a reminder will get lost. A one-time visit fits owners who keep good records and do not mind booking it each year. Either way, the generator needs a full service at least once a year to stay ready.

04

Moving your generator to Wired

If another company maintained your generator before, or nobody has in a while, you can move it to Wired at any time. Tell us the brand, model and the last service date you know of. On the first visit, we bring the unit up to date on the factory schedule, check the battery and transfer switch, and start a clean service record from there.

After the Visit: Reports, Repairs and Records

A maintenance visit should leave you knowing more about your generator than before. Here is what happens once the technician is done.

01

The summary report

After every service, you get a summary of what was done and what the technician saw: oil and filter work, battery test results, the condition of the enclosure and wiring, and how the transfer test went. If something is starting to wear but does not need attention yet, the report says so. That way nothing about your generator comes as a surprise later.

02

When the technician finds a problem

Maintenance sometimes turns up a part that is failing, like a weak battery, a worn starter or a loose gas connection. The technician explains what it is and why it matters, and we tell you what the repair involves before any work is done. Small items can often be handled on the same visit. Bigger ones get scheduled with you.

03

Service records and your warranty

Warranty providers can ask for proof that a generator was maintained. Keep the summary report from every visit in one place, along with your model and serial number. We keep records of the service we do as well. If you are not sure what your warranty requires, check its terms or ask us, and we will help you read it.

04

Bought a house that came with a generator

Houses across the Houston area often come with a standby generator already in the yard. If yours did, book a service visit soon after you move in. You may not know when it was last maintained. We check its condition, help you set up Mobile Link if the unit supports it, and show you how the controller and weekly exercise work.

What annual generator service includes

A standby generator can sit idle for months, and the parts that wear out when it is not running are the ones that fail on the night you need it.

01

Oil and filter change

Oil breaks down over time even if the engine has barely run. We drain the old oil, replace the oil filter, and refill to the level the manufacturer calls for. Fresh oil protects the engine during a long outage, when it may need to run for many hours at a stretch. We also look at the oil for signs of contamination, record the hours on the unit, and note anything that should be watched before your next visit.

02

Battery test and replacement

A weak battery is one of the most common reasons a generator fails to start. We test the battery, clean the terminals, and check the charger. If it is near the end of its life, we replace it during the visit rather than leave you with a surprise at the next outage. Heat is hard on batteries in Houston, so one that tested fine last year may be weak now. Replacing it on a planned visit is far less trouble than finding out it is dead after the lights go out.

03

Air filter, spark plugs and engine inspection

We check the air filter, spark plugs, belts, hoses and fuel connections, and look for leaks, corrosion, and signs of pests in the enclosure. Worn parts get replaced on the schedule the manufacturer recommends, not guessed at. A clogged air filter or worn plugs make the engine work harder and start less reliably. We also check that the vents and louvers on the enclosure are clear, because a generator needs airflow to run safely.

04

Test run under load

A generator that starts is not the same as one that carries your house. We run it, watch it take the load through the transfer switch, and check voltage and frequency while it runs. You get a clear report of what we found and what needs attention. Anything unusual, such as a rough start, a slow transfer or a warning on the controller, goes in the report so you know exactly what we saw.

05

When to schedule it

Before storm season is the best time, so any parts that need replacing are handled before an outage or a storm. If your generator has not been serviced in over a year, or has run through a long outage, book a visit. If you have a Shield Protection plan, the visit is on our calendar for you. If not, call (713) 467-1125 and we will find a time that fits before the weather turns.

Generator will not start, or shows an error code

When a generator misbehaves, the cause is usually one of a short list. Here is how we think about it.

01

Generator will not start

A dead battery, a closed fuel valve, low oil, a tripped breaker on the unit, or a failed sensor can all stop a start. If you hear it cranking but not catching, fuel or spark may be at fault. If nothing happens, think battery or controller. Do not keep cranking, which can drain the battery and damage the starter. Note what the controller shows and whether the unit made any sound, then call. That information helps us decide what to bring and whether a repair visit can fix it in one trip.

02

Error codes and warning lights

Most standby generators show a code or a light on the controller when something is wrong, such as low oil pressure, overspeed, a failed start, or a battery fault. Write down the code and the date, then call us. The code narrows the search, and we bring parts for the common ones. Please do not clear a code and carry on, because the history helps us find an intermittent problem. If the generator has shut itself down, leave it off until it has been looked at.

03

Runs, but the power does not come on

If the generator is running and the house is still dark, the problem may be the transfer switch rather than the generator. A switch that does not move, or a tripped main breaker on the generator, can cause this. We test the switch and the wiring between the two. A transfer switch is part of the system and gets checked at annual service, so a switch that has not been tested in years is a common culprit. We can test it and repair or replace it.

04

Runs rough, surges or shuts down

A generator that surges, stalls under load, or shuts down after a few minutes may have a fuel problem, a dirty filter, or a sensor fault. Fuel that sat through a long summer can be part of it. A service visit usually finds the cause. Do not keep restarting a unit that keeps shutting down. Repeated attempts can hide the cause or damage parts. Write down what happened before it stopped and call us with the details.

What a generator repair visit involves

If something has already failed, here is what to expect when you call.

01

The phone call

Tell us the brand and model, what the unit did or did not do, any code on the screen, and when it last had service. Photos of the controller and the data label help. We will tell you when a technician can come out. If you can reach the unit safely, tell us whether the screen shows a code and whether anything has changed recently, such as a storm, a fuel delivery or a recent service.

02

Diagnosis on site

We check the battery, fuel, oil level, controller, and transfer switch, read any stored codes, and test the unit under load. We explain what failed and what the repair involves before we start. Our technicians test before they replace anything, so you do not pay for parts that were not the problem. If the unit is under a manufacturer's warranty, we tell you what we see so you can decide how to proceed.

03

Repair, parts and testing

Where the part is on the truck we fix it that day. If it has to be ordered, we make the generator as safe as we can and return once the part arrives. After the repair we run the unit again to confirm it starts and carries the load. You get a plain explanation of what was wrong and what we did, and we recommend annual service so the same problem is less likely to come back.

04

Other brands and portable units

Tell us the brand when you call. We install and service Generac standby generators, and we will say honestly whether we can work on another make. For portable generators, we can set up a safe, permitted way to connect one to the house. Tell us the brand and the model, and we will say what we can do. Our shop is in Tomball and we serve the Houston area, so call (713) 467-1125.

Our technicians handle generator maintenance Houston homeowners count on, along with Cypress, The Woodlands, Katy, Spring and the rest of the Greater Houston area. If you typed generator maintenance near me, generator service near me, or generator service in my area, the answer is a call to (713) 467-1125 and a visit from our own crews.

02

Generator service Houston and generator service in Houston

Generator service in Houston means different things to different people: an annual visit, a repair after a storm, or a check before hurricane season. We do all of them. Generator service Houston customers book with us includes the same careful inspection whether the unit is new or years old. We also handle electrical service Houston homes need around the generator, such as the transfer switch and panel.

03

Generator maintenance company and generator service company near me

Choosing a generator maintenance company, or a generator service company near me, comes down to who shows up and whether they know your equipment. We are a Generac Prestige Dealer, so Generac is what we work on most, and we service all brands. You get a licensed electrician rather than a call center. Ask for a generator maintenance company near me that answers the phone, and call us any time of day, since our emergency line is open 24/7.

04

Best generator maintenance near me: what to look for

People search for the best generator maintenance near me hoping to find someone reliable. Look for a company that is licensed and insured, has a real shop you can visit, works on your brand, and explains what they did in plain words. We have a showroom at 13910 Alice Road in Tomball, and our crews have serviced generators for years. We would rather earn the call than claim the title.

05

Generator maintenance technician and generator maintenance work

Generator and maintenance go together, and a generator maintenance service visit is more than an oil change. A generator maintenance technician does more than change oil. Generator maintenance work includes inspecting the engine, the battery, the fuel supply, the electrical connections and the transfer switch, then running the unit to confirm it carries a load. Our technicians are trained on the equipment and know the usual failure points. They tell you what they found, what is fine and what is worth watching.

06

Generator installation and service, installation services near me

Some customers want one company for generator installation and service. We install Generac standby generators, set the pad, run the gas and electrical, pull the permit, and then service the unit afterward. If you were looking for generator installation services, or generator installation services near me, see our installation page, and know that the crew that installs it also knows how to maintain it.

Generac Generator Service and Maintenance Schedule

Generac is the brand we know best, so here is how we approach it.

01

Generac generator maintenance and Generac generator service near me

Generac generator maintenance is the planned visit that keeps a standby unit ready. A generac generator service Houston visit covers oil and filter, spark plugs where needed, the battery, the air filter and a test run under load. Generac generator maintenance near me, or generator maintenance Generac, is the same visit. Whether you search Generac generator service, generac generator service near me, generator generac maintenance near me or generator generac service near me, it reaches us: a Generac Prestige Dealer in Tomball.

02

Generac generator maintenance schedule and standby generator maintenance schedule

The Generac generator maintenance schedule follows the manual for your model, and the usual pattern is a yearly service with attention sooner if it runs a lot. A Generac standby generator maintenance schedule also includes the weekly self-test the unit runs on its own. A standby generator maintenance schedule, or generator maintenance schedule, should be written down so nothing is missed. We keep track and call when yours is due.

03

Generac generator yearly maintenance and yearly service

Generac generator yearly maintenance means one thorough visit each year. The Generac generator yearly service covers the fluids, filters, battery and a test of the transfer switch. Generator yearly maintenance, generator yearly service and generator annual maintenance all describe the same idea. If your generator runs through long outages, ask us about an earlier visit, since hours of running time matter as much as the calendar.

04

Generator maintenance frequency

Generator maintenance frequency depends on the unit and how much it runs. For most home standby generators it is once a year, and sooner after a long outage, because oil and filters work hard when the generator runs for days. Follow the manual for your model, and call us if you are unsure. We would rather check a generator that is fine than miss one that is not.

Standby and Whole House Generator Maintenance

A generator you depend on deserves a routine.

01

Standby generator maintenance and whole house generator maintenance

Standby generator maintenance keeps the generator ready for the next outage. Maintenance for whole house generator owners is the same set of tasks: fluids, filters, battery, connections and a test under load. A generator for house maintenance plan makes sure the unit starts, the transfer switch moves, and the house gets power. Whole house generator maintenance near me, or standby generator maintenance near me, brings the same answer: call Wired.

02

Whole house generator service, tune up and service near me

Whole house generator service and a whole house generator tune up are what we call an annual visit. Whole house generator service near me means a technician who can reach you from Tomball, and standby generator service near me means the same. A tune up replaces wear items, checks the engine and verifies the output. A standby generator service visit finishes with a test, and we show you the result.

03

Standby generator maintenance checklist

A standby generator maintenance checklist includes checking the oil level and condition, replacing the filter, inspecting the air filter and spark plugs, testing the battery, looking for leaks, cleaning around the unit, confirming the fuel supply, and running the generator with the house load transferred. Generator daily maintenance checklist sheets are written for commercial or continuous-duty units. Homeowners do not need daily checks. A yearly visit and a quick look every month are plenty.

04

Gas generator maintenance and generator fuel maintenance

Gas generator maintenance means looking at the natural gas or propane connections, the regulator and the pressure. Generator fuel maintenance matters more for propane tanks and diesel units, where fuel level and quality must be watched. For a gas generator we check for leaks with the right equipment and make sure the fuel supply meets what the generator needs. If you ever smell gas, leave the area and call your gas utility.

05

Generator battery maintenance and generator maintenance oil

Generator battery maintenance is one of the main reasons a generator fails to start, so we test and replace the battery as needed. Generator maintenance oil work means changing the oil and filter on schedule using the type the manufacturer calls for. Fresh oil protects the engine and a good battery starts it. These two items cause many of the no-start calls we see.

06

Generator electrical maintenance and generator set maintenance

Generator electrical maintenance covers the connections, the controller, the breaker on the unit and the transfer switch. Generator set maintenance is the broader term, meaning the engine and the alternator together. Loose or corroded connections cause trouble, and they are easy to find on a planned visit. We tighten, clean and test, so the generator set delivers clean power when it counts.

Maintenance Plans, Reports and Repairs

What you get at the end of the visit, and what happens when something is wrong.

01

Generator maintenance plans near me

Generator maintenance plans near me can mean a yearly contract or a single scheduled visit. We keep it simple. We schedule your annual service, remind you when it is due, and handle the visit. Ask about plan options when you call, and we will tell you what is available for your generator and how the visits are scheduled.

02

Generator maintenance report, service report and log sheet

After a visit you should know what was done. A generator maintenance report or generator service report lists what we checked and replaced and anything we recommend. A generator maintenance log sheet is a running record of oil changes, tests and service dates that makes the next visit easier and helps with warranty questions. Ask us for the paperwork when we finish.

03

Generator maintenance and repairs, generator service work

Generator maintenance service near me covers planned visits, while repairs fix a failure. Generator maintenance and repairs are different jobs, but they go together. Maintenance prevents most breakdowns. If something has already failed, our generator service work includes diagnosing the problem, replacing parts and testing the unit. We repair generators we did not install, and parts are ordered if we do not have them on the truck.

04

Generator maintenance parts and tools

Generator maintenance parts include oil, filters, spark plugs and batteries. Generator maintenance tools range from a multimeter to load testing equipment, and a technician carries them. You do not need to buy parts or tools yourself. We bring what the visit requires, use the correct parts for your model, and leave the generator ready to run.

05

Generator repair shops and generator service at home

Many people picture a generator repair shop where you drop the unit off, but a standby generator cannot be moved. Our shop is in Tomball, and our trucks come to you. Generator service at home is how we work: a technician arrives at your house, diagnoses the generator in place and repairs it there. Portable units can also come to the shop.

06

Kohler and Other Brands We Service

We install Generac, and we service all brands.

01

Kohler generator service, maintenance and service company near me

We service all generator brands, Kohler included. Kohler generator service Houston owners ask for, such as Kohler generator maintenance, Kohler generator maintenance near me or a Kohler generator maintenance schedule, is work we do. If you are looking for a Kohler generator service company, a Kohler generator maintenance company, a Kohler generator service company near me, or the best Kohler generator service near me, call us and tell us the model. We do not sell Kohler units.

02

Kohler generator shutdowns, low voltage and frequency errors

A Kohler generator engine speed low shutdown, a Kohler generator low frequency shutdown or high frequency shutdown, a Kohler generator under frequency error and a Kohler generator under voltage shutdown all say something specific about what the controller saw. A Kohler generator keeps shutting down, or a Kohler generator not turning on, can trace to fuel supply, a voltage regulator (a Kohler generator voltage regulator location is behind panels a technician opens), the battery or a loose connection. A technician reads the controller and tests the unit. Call us with what the display shows.

03

Kohler generator exercise cycle

The Kohler generator exercise cycle is like most standby generators, which run a short weekly exercise cycle on their own. That cycle keeps parts moving and shows if something is wrong. If your generator skips the exercise cycle, shows a fault, or will not start, it needs a look. We check the schedule and settings during a service visit.

Generac maintenance and annual generator service

A standby generator sits for months and has to start the one night it matters. Annual maintenance is how you make sure it does.

01

Generac maintenance

Oil and filter, battery test, a look at the belts, hoses and fuel connections, and a test run under load. Generac asks for service on a schedule, and we do it the way the manual says.

02

Generator annual maintenance

Once a year, before storm season. We write down what we found and tell you if anything needs attention before it becomes a repair.

03

Skip the reminder: Shield Protection

Shield Protection plans put the visit on our calendar for you, with monitoring and storm priority. See the plans.

Questions we get every week

Ask us anything. These come up most.

How often does a Generac generator need maintenance?

Once a year at minimum, and sooner if it runs a lot during storms. The annual visit covers oil, filter, battery and a test run.

Is a maintenance visit the same as a repair?

No. Maintenance is the planned visit that keeps it ready. A repair is when something has already failed. Maintenance is how you avoid most repairs.

How often should I have my Generac generator serviced?

Once a year is the usual answer for a home standby generator, and sooner if it ran for a long outage. Follow the manual for your model, and call (713) 467-1125 if you are not sure.

How much does generator maintenance cost?

It depends on the generator size and type, what the manufacturer calls for, and whether any parts need replacing. Wired does not post prices. A free visit gets you a written estimate.

What is the generator operating cost?

Generator operating cost depends on the fuel type, the size of the unit, how much of the house it runs, and how long outages last. We cannot give a single figure. We can talk through your generator and your usage on a free visit.

Do you offer generator service near me in Houston?

Yes. We serve Tomball, Houston, Cypress, The Woodlands, Katy, Spring, Magnolia, Conroe, Humble, Fulshear, Memorial, Jersey Village and the rest of Greater Houston. Call (713) 467-1125.

Do you service Kohler generators?

Yes. We install Generac and service all brands, Kohler included. We do not sell Kohler units.

What is the generator maintenance frequency for a Generac?

Plan on one full service each year, plus a quick look now and then. Heavy use after long outages calls for an earlier visit.

How often should a Generac generator be serviced?

Generac sets intervals by hours and time, whichever comes first. For most homes that means once a year, and sooner after heavy storm use. We follow the schedule in the manual for your model.

Can I do my own generator maintenance?

Owners can keep the area clear, watch the weekly test, check the controller is in AUTO and keep propane topped up. Opening the enclosure for oil, plugs and valve work involves a live battery, an automatic start and connections to your home's power. For safety and a clean service record, leave that to a trained technician.

What does the maintenance light on my Generac mean?

It usually means service is due by time or run hours. The generator still works, but it is asking for its scheduled maintenance. We service it and reset the reminder. If the light is red or shows a fault code instead, write the code down and call us.

Does annual maintenance include a new battery?

The visit includes testing the battery and charger. Replacing the battery is a separate part when it is needed. We tell you if it is weak before we replace anything.

Will you service a generator you did not install?

Yes. We maintain Generac, Kohler and other brands whether or not we installed them. The first visit catches the unit up and then it goes on a yearly schedule.

Why does my generator need service if it runs fine every week?

The weekly test only proves it can start and run briefly with no load. Maintenance replaces worn oil and parts, tests the battery under load and checks the transfer switch, which is what keeps it running for days during a real outage.

Do you offer generator maintenance near me?

Wired is based in Tomball with technicians serving Houston and the surrounding area. Call (713) 467-1125 any time. Phones are open 24/7.

Will regular maintenance keep my Generac warranty valid?

Following the factory maintenance schedule and keeping records of each service is the best way to protect your warranty. Warranty terms vary, so check yours. As a Generac Prestige Dealer, we follow the Generac schedule, use Generac parts and give you a summary after each visit that you can keep with your records.

What happens if the technician finds a problem during maintenance?

The technician explains what was found and why it matters, and we tell you what the repair involves and costs before any work is done. Small fixes can often be done on the same visit. Larger repairs or parts that need to be ordered get scheduled with you.

Is a maintenance plan better than paying for one visit at a time?

Both keep the generator serviced. A Shield Protection plan schedules the service for you and adds benefits like monitoring and storm priority, so it suits people who would rather not keep track. Paying per visit suits owners who are good about booking service every year before storm season.

I bought a house with a generator. What should I do first?

Book a service visit, since you may not know when it was last maintained. We check the battery, oil, wiring and transfer switch, set it back on the factory schedule, help you set up Mobile Link if the unit supports it, and show you how the controller and weekly exercise work.

What does it cost to run a standby generator?

It depends on the fuel (natural gas or propane), the size of the unit and how long and how hard it runs during an outage. Maintenance is the other part: a yearly service visit keeps it ready. We can walk through both for your generator on a free visit.

Do you repair generators near Tomball and Houston?

Yes. We service and repair Generac standby generators across the Houston area, from routine maintenance to a unit that will not start. Call (713) 467-1125 and tell us the model and any error codes or lights you see.

How often should a standby generator be serviced?

At least once a year, and before hurricane season is a good time. Check your owner's manual for your unit's schedule, and call us if the generator has not run its weekly exercise cycle or shows a warning.
