Generac Generators — Dealer, Installation & Service in Houston
Generac Prestige DealerGenerac's highest dealer designation. We sell, install and service Generac home standby generators.
Generac generatorsGenerac Dealer in Houston: What Prestige Dealer Means for You
When you search for a Generac dealer near me, you will find stores, online sellers and installers. A dealer that sells, installs and services the unit is a different thing from a place that only sells the box.
Sales, installation and service under one roof
As a Generac Prestige Dealer, Wired sells the generator, installs it with our own licensed electricians and services it after it is running. You have one company to call for the sizing, the permit, the install, the yearly service and any repair. That matters during a storm, when you want the same people who put the unit in to be the ones who answer the phone.
Trained on Generac equipment
Generac standby generators have their own controllers, alarms, transfer switches and setup steps. Our technicians work on this equipment every week, so they know where to look when something goes wrong and how to set it up right the first time. Getting the install right is the best way to avoid service calls later. It also means fewer return trips, because the tech arriving at your house already knows the unit in your yard.
A local showroom in Tomball
Our showroom at 13910 Alice Road in Tomball lets you see Generac units in person before you buy. You can look at the size of the enclosure, hear what one sounds like and ask questions face to face. Many people find it easier to choose after they have stood next to a few models. Call ahead at (713) 467-1125 if you want someone ready to walk you through the units when you arrive.
Generac Guardian Generator Sizes and Models
People often ask what size Generac generators come in. The home standby lineup covers a wide range, from units that back up the essentials to units that carry a whole house.
Air-cooled Guardian home standby units
The Generac Guardian series is the air-cooled home standby line most houses use. It runs from smaller essentials units up to whole-home models in the 26 to 28kW range. You can see the models we carry on our generator pages, including the 18kW, 22kW, 24kW, 26kW and 28kW units. Each one runs on natural gas or propane and starts on its own when the power goes out.
Liquid-cooled Protector series for larger homes
Very large homes, homes with several big AC systems and light commercial buildings sometimes need more than an air-cooled unit can give. Generac's liquid-cooled Protector series covers those larger loads. These units are bigger and are planned differently, so we look closely at your service, gas supply and placement before recommending one. If an air-cooled unit with load management can do the job, we tell you that first.
What is the smallest Generac whole house generator?
The smallest home standby units are made to back up essential circuits, not every appliance at once. They can be a good fit for a smaller home or a tight budget, as long as you know what they will and will not run. We explain the tradeoff plainly, so you are not surprised when the AC does not come on during an outage.
How a Generac Standby Generator Works
A standby generator is built to work without you. Here is what happens from the moment the grid goes down.
The automatic transfer switch
The transfer switch watches the power coming from the utility. When it drops, the switch signals the generator to start, then moves your house from the grid to the generator once the engine is ready. When utility power comes back and holds steady, it moves the house back and the generator cools down and shuts off. You do not have to flip anything.
Weekly exercise and quiet test
A Generac standby generator runs a short exercise cycle on a schedule to keep the engine and battery ready. Many models run this test at a lower speed so it is quieter. If you hear your generator run briefly once a week with the power on, that is normal and it is a good sign. If it stops running its test, or shows a warning afterward, that is the time to call.
Mobile Link and checking status from your phone
Generac Mobile Link lets you check your generator's status from your phone, see when it last ran and get alerts if something needs attention. It is useful when you travel during storm season. We can help you set it up during the install so you are not doing it in the dark. If the app shows a fault, send us a screenshot and we can often tell you what it means before a visit.
Is Generac Any Good? Generac vs Kohler and Other Brands
These are fair questions, and we would rather answer them straight than sell around them.
Why we install Generac
Generac is the most widely installed home standby brand, and parts and support are easy to get in the Houston area. That makes a difference after a storm, when parts for less common brands can take longer to arrive. We chose to be a Generac dealer because we can stand behind the equipment and service it quickly. Being a dealer also means we can handle warranty claims on the Generac units we service.
Generac vs Kohler
Kohler also makes good home standby generators, and some homeowners prefer them. Both brands make reliable units when they are sized right, installed right and serviced on schedule. Those three things matter more than the badge on the enclosure. We install Generac, and we also service Kohler and other brands if you already own one. If you are deciding between brands, ask us anything. We will tell you what we know and where we would send you for the other side.
Generac vs Briggs and Stratton, Cummins and portables
Other standby brands exist, and each has its own dealer network. Portable generators from brands like Honda, Westinghouse or Predator are a different product. They power less, need gasoline or a tank and have to be started and refueled by hand. They can work as a budget backup with a proper transfer switch or interlock, but they are not a replacement for an automatic standby unit.
Generac Generator Service, Repair and Parts Near Houston
Buying a Generac is the start. Keeping it ready is what makes it pay off when the next storm comes through.
Generac generator maintenance
Generac standby generators need oil and filter changes, spark plugs, battery testing and an inspection on a regular schedule. Most owners book once a year, ideally before hurricane season, and more often if the unit has run a lot. We also check the transfer switch and read the controller's fault history so small issues get caught early. Keeping service records also helps if you ever need a warranty claim.
Generac generator repair
If your Generac will not start, shows a fault on the controller or runs but does not power the house, call us. Write down any code on the display before you call. Our phones are open 24/7 at (713) 467-1125, and we tell you when a technician can be there. Do not open the transfer switch or the panel, and do not keep cranking a unit that will not start, because that wears the battery and starter.
Generac parts near me
Batteries, filters, spark plugs and common wear parts are part of normal service. Bigger parts such as controllers and transfer switch components are ordered for the specific model. As a Generac dealer, we can source factory parts for your unit and install them correctly. Using the correct part for your model matters, because a near match can cause new faults. Tell us your model and serial number when you call and we can check what you need.
Buying a Generac Generator in Houston: What to Expect
From the first call to the first test run, here is the path most homeowners follow.
Free sizing visit
We come to your home, look at your electrical panel, gas meter or propane supply and the spot where the generator can sit. We ask what you need to keep running, such as AC units, the fridge, medical equipment, a well or a sump pump. Then we recommend a Generac model and give you a written estimate. The visit is free, and there is no pressure to decide on the spot.
Permits, install and startup
We pull the permits, set the pad, run the gas and electrical connections, install the transfer switch and schedule the inspection. After the unit passes, we start it up, test a transfer and walk you through how it works. You will know what normal looks like and what to do if a light comes on. We also leave you with the paperwork for your records.
Why buy from a dealer instead of a big box store
You can buy some Generac units at big box stores or warehouse clubs, but you still need someone to size it, install it, permit it and service it. Buying from a dealer puts all of that with one company. If something goes wrong later, you have one number to call instead of a store and a separate contractor. A dealer can also handle warranty claims on the unit.
Generac Warranty and Shield Protection Plans
Buying from a dealer is also about what happens after the install. Here is how warranty and service work with Wired.
Free 10-year warranty on new air-cooled installs
When Wired installs a new air-cooled Generac home standby generator, it comes with a free 10-year warranty. Air-cooled units are the Guardian models that cover most Houston homes. Ask us how the warranty applies to the model you are looking at, and what it covers, before you sign. Liquid-cooled Protector units for larger homes carry their own terms, and we explain those on the visit.
Warranty registration at startup
A warranty only helps if it is on file. We register your generator at startup, so you are not left to fill out forms after the crew leaves. Keep the paperwork we hand you with your other house records. If you ever sell the house, the permit, the registration and the service history make it easier to answer a buyer's questions about the generator.
Shield Protection maintenance plans
A Generac is an engine, and engines need oil, filters, spark plugs and a battery check. We recommend service once a year, ideally before hurricane season. Our Shield Protection plans put that service on a schedule, so the reminder comes from us instead of from a failed start during a storm. Ask about the plan levels when you get your estimate or call about an existing unit.
Service for units already in your yard
You do not have to have bought from us to get help. Wired services Generac generators installed by other companies, and Kohler units too. If yours shows a warning on Mobile Link, will not exercise or did not start during the last outage, call (713) 467-1125. Our phones are open 24/7, and a licensed technician can come out to find the problem.
Where We Install and Service Generac Generators
Our showroom and shop are in Tomball, and our crews cover Houston and the surrounding areas.
Tomball and northwest Houston
Tomball is home, so the communities along Highway 249, FM 2920 and the Grand Parkway are close by. Many of these neighborhoods sit under long, tree-lined power lines that can take a while to restore after a big storm. If you live nearby, you can stop by the Alice Road showroom to see Generac units in person before the sizing visit.
Cypress, Katy and the west side
West of Houston, many homes are newer two-story houses in master-planned communities with two air conditioners and an HOA that reviews exterior changes. We size the generator around both AC systems and prepare the HOA package with the site plan. Acreage out toward Hockley and Waller often adds a well pump to the list, and some of those homes run on propane.
Spring, The Woodlands, Conroe and Magnolia
North of Houston, we install Generac generators in Spring, The Woodlands, Conroe, Magnolia and the towns between them. Heavy tree cover in these areas means storm damage to lines is common. Permits may come from a city or from Harris or Montgomery County depending on your address, and we pull whichever one applies so you do not have to figure it out.
Kingwood, Humble, Sugar Land and Pearland
We also cover the east and south sides of the area, including Kingwood, Humble, Sugar Land, Pearland, Richmond and nearby towns. Each city has its own permit office and rules, and many neighborhoods have an HOA review. Wherever you are in Houston and the surrounding areas, the process is the same: a free sizing visit, a written estimate, permits handled and an install by our crews.
Generac Generator Cost, Sizing and Financing Questions
Cost and size are the top two questions we hear about Generac generators. We do not post a price, because the unit, the gas line, the pad and the permit all change the number.
What makes up a Generac generator estimate
The generator itself, the transfer switch, the pad, the gas line, electrical work, the permit and the inspection. Any extras, such as a larger transfer switch or a longer pipe run, change the total. A free visit lets us see the house, the meter and the panel and give a written estimate. Everything is listed in writing, so you can compare it with other estimates line by line.
What size Generac for your house
Sizing starts with what you want to run, not the square footage alone. A 1500 sq ft house and a 3000 sq ft house can need the same unit or different ones, depending on AC tonnage, electric heat, a pool pump or a well. We run the numbers on a free sizing visit. Our online sizing tool is a good start, and the visit confirms it. Choosing too small leaves loads off, and choosing too large costs more for no benefit.
Whole house generator yearly maintenance
A standby generator needs regular service, usually once a year, with oil and filter changes, a battery check and a test run. The cost depends on the model and what is due. Our maintenance page explains what is included. A maintained unit starts when you need it. Skipping service is the most common reason a generator fails to start when the power goes out, so we recommend booking it before storm season.
Financing a Generac installation
Financing is available through our lending partners, subject to credit approval. Ask when you get your estimate and we can show you the options. We do not promise terms here because they change, so confirm them with our team before you decide. Financing details, including plans through Synchrony or Leighton Lending, are available from our team when you ask for an estimate.
Generac Lights, Error Codes and Troubleshooting
If your Generac is not behaving, here is how to approach it before you call. We service Generac and other brands.
What the green and yellow lights mean
The status lights and the display on the controller show whether the unit is ready, running or has a fault. Meanings differ between controller types, so check your owner's manual. A steady or flashing light that you are unsure about is worth a photo. Send it to us and we will tell you what it means. Do not ignore a light that has changed, since it may be an early warning that the unit needs attention before the next outage.
Error codes such as 1100, 1300, 1505, 1600 and 2800
A numbered code points to the kind of fault the controller found, such as a start, speed, sensor or battery problem. Do not keep resetting it to see if it goes away. Write the code down, take a photo of the screen, and call (713) 467-1125. The code helps us bring the right parts. Searches for specific codes are common, but the same number can have different causes on different models, so we read it with the model and history in mind.
Generator will not start, shuts off or keeps blowing a fuse
A low battery, low oil, a closed gas valve, a tripped breaker or a failed sensor can each stop a generator. A fuse that keeps blowing points to an electrical fault that needs a technician. Please do not keep replacing it, and do not jump-start a standby unit. Tell us what happened just before it stopped, such as a storm, a long run or a recent service. That detail speeds up the diagnosis.
Oil or fuel leaks, low oil pressure and Wi-Fi loss
Low oil pressure alarms need attention before the engine is run again. If you smell gas, leave the area and call the gas utility first. An oil leak should be looked at before the next run. A unit that keeps losing its Wi-Fi connection is usually a signal or router issue we can help sort out. Fuel and oil leaks are not DIY repairs. Turn the unit off and call us, and keep children and pets away from the area until it is checked.
Generac Models, Placement and Accessories
Beyond the big questions, there are many smaller ones about the unit itself. These come up often before an install.
Standby Generac versus portable Generac models
The GP and iQ lines are portable generators that you move and fuel yourself. A Guardian standby unit is fixed outside, runs on natural gas or propane and starts automatically. They solve different problems. Check what we have on our inventory page, or call and we will help you pick. A standby unit also needs a transfer switch, and a portable one needs a safe way to connect, so ask about both when you compare.
Dimensions, placement and noise level
The unit needs clearance from the house, windows, vents and the property line, and a level pad. Dimensions and sound levels vary by model, so look up the spec sheet for the one you like. We check the local rules and the manufacturer's clearances when we plan the placement. Neighbors matter too. We consider where the sound goes and how close the unit is to bedrooms and property lines when picking the spot.
Gas line sizing and the installation process
The gas pipe must be large enough for the generator and the other appliances on the meter. We check that and the gas pressure before the install. We pull the permit, set the pad, run the gas and electrical, and test the unit. The inspection is scheduled before it is final. Natural gas or propane both work, and we help you decide which is more practical for your property and your budget.
Oil change interval, accessories and carbon monoxide safety
Follow the oil change interval in the manual and have a technician do the annual service. Accessories such as exhaust extensions or silencer kits should be approved for the model. Carbon monoxide sensors on a unit are there for safety and should never be bypassed. Generators belong outside, well away from windows. Never run a generator in a garage or near an open window. If you are unsure about an accessory, ask us before you buy it.
Generac Generator Cost, Power and Whole House Questions
The questions homeowners ask first, answered without posting prices.
Generac generator average cost and whole house generator average cost
People search for the Generac generator average cost and the whole house generator average cost, and an average does not help much because every house is different. The cost depends on the unit size, the fuel, the distance from the gas line, the pad, the transfer switch, the permit and any panel work. Wired does not post prices. A free visit gets you a written estimate for your house, and financing is available subject to credit approval.
Generac generator how many watts and whole house generator wattage
Generac generator how many watts is really a sizing question. Home standby units are rated in kilowatts, from 10 to 32 kW in our line. Whole house generator how many watts you need depends on the air conditioners, the electric appliances, the pool or EV charger and what you want running together. Whole house generator wattage is worked out from a load calculation, which we do on the free visit, not from a guess.
Whole house generator vs partial
A whole house generator vs partial setup is a choice about circuits. A whole house unit is sized and wired so every circuit stays on. A partial setup backs up the essentials, such as the fridge, lights, internet, and one or two air conditioners, using a smaller generator and a smaller transfer switch. Think about how long outages last and what you cannot live without, and we will help you pick.
Whole house generator propane usage
Whole house generator propane usage depends on the size of the generator, how much of the house is running, and how long the outage lasts. A bigger load uses more fuel. Natural gas has no tank to refill, while propane needs a tank sized for the outage you expect. We talk through fuel on the visit so you are not surprised.
Whole house generator extension cord
A whole house generator extension cord is not something to use. A standby generator is wired permanently into the house through a transfer switch and does not run on extension cords. Portable generators are different, and even they should connect through a proper inlet. Running cords through windows or doors is risky for carbon monoxide and fire. Ask us about a safe setup.
Generac Generator vs Solar and Batteries
Many homeowners compare a generator to solar. Here is the honest comparison.
Whole house generator vs solar, solar panels and solar battery
A whole house generator vs solar comparison is really about what you need during an outage. Whole house generator vs solar panels: panels make power when the sun is up and usually shut off during a grid outage unless the system is built for it. Whole house generator vs solar battery: batteries hold a limited amount of energy, while a generator runs as long as it has fuel. Many homes use a generator for long outages. We install generators and do not sell solar.
Generac generator vs solar panels and standby generator vs solar battery
Generac generator vs solar panels, or a standby generator vs solar battery, depends on your priorities. A battery is quiet and needs no fuel, but it can run out. A generator can run for days but makes noise and uses gas or propane. A whole home generator vs solar choice is also about how much of the house you need on. Call us and we will go through it honestly.
Whole house generator solar powered and tax credit
Is a whole house generator solar powered? No, a standby generator runs on natural gas or propane. A solar powered whole house generator is not something we install. On the whole house generator tax credit, or the whole house generator tax credit 2025, we are electricians and not tax advisors, so we cannot promise any credit. Ask your tax professional before you count on one.
Is a Generac Generator Good or Bad?
Honest answers about the brand we sell and the brands we do not.
Generac generator good or bad
Is a Generac generator good or bad? We are a Generac Prestige Dealer, so you should weigh our view accordingly. What we can say is that Generac is the standby generator we install every week, parts and service are easy to get, and a generator that is installed properly and maintained each year is far more likely to start when you need it. Call and ask us anything, including the downsides.
Kohler generator vs Generac pros and cons
A Kohler generator vs Generac pros and cons conversation is common. Both are well-known brands. We install Generac, and we service Kohler. Compare size, fuel, warranty, and who will service the unit near you. We would rather you ask local installers about parts and support than choose on a spec sheet. We will talk it through plainly.
Whole house generator brands to avoid
Whole house generator brands to avoid is a question we get. We do not name brands to avoid, but we suggest asking any brand three things: is there a local dealer, can a technician reach you quickly, and are parts available. A generator with no local service is hard to keep running. We install Generac and service all brands.
Generac Generator Troubleshooting
These are the problems that bring most calls. For any of them, call us at (713) 467-1125.
Generac generator just stopped working
If a Generac generator just stopped working, check that the controller is set to Auto, that the unit breaker is on and that the fuel supply is open. Note the code or light shown. Do not open the transfer switch or panel. Then call us. A dead battery or a fault the controller is showing are common causes, and a technician can find which.
Generac generator keeps shutting off
A Generac generator that keeps shutting off is trying to protect itself or the house. It can be low oil, an overload, a fuel supply problem, a sensor fault or a loose connection. Write down the error code or the lights before you call. We read the controller, check the unit and tell you what needs to be fixed.
Generac generator leaking oil or gas
A Generac generator leaking oil needs a technician. A Generac generator leaking gas is more urgent: if you smell gas, move away from the unit, shut off the gas if you can do so safely, and call your gas utility. Then call us. Do not run the generator until a leak is found and fixed.
Generac generator RPM sensor loss
A Generac generator RPM sensor loss message means the controller is not seeing engine speed. The cause can be a sensor, a wire or something on the engine. It may stop the generator from starting or make it shut down. A technician tests the sensor and the wiring. Call us with the code.
Resetting a Generac 22kW generator
People search for resetting Generac 22kW generator steps when it shows a fault. Clearing the fault without finding the cause hides the problem. You can turn the controller off, wait, and try Auto again, but if it comes back, stop and call. We read the code, fix the cause and reset it properly.
Generac Specs, Placement and Parts
Reference questions about the unit itself.
Generac generator oil capacity, oil type and capacity chart
The Generac generator oil capacity chart and the Generac generator oil type and capacity depend on the model, because air-cooled and liquid-cooled engines differ. The manual and the label inside the unit list the oil type and the amount. We use what the manufacturer calls for at every service. If you are unsure, tell us your model.
Generac generator battery charger location and voltage regulator location
The Generac generator battery charger location and Generac generator voltage regulator location vary by model. Both are inside the unit, behind panels that should only be opened by a technician. The charger keeps the battery topped up, and the regulator controls output voltage. If you suspect either is failing, call us.
Generac generator noise level chart and quiet muffler
A Generac generator noise level chart gives decibel readings for each model, measured under set conditions. Real noise depends on placement and what is nearby. A Generac generator quiet muffler can reduce noise on some units. We think about neighbors and bedroom windows when we choose the spot, and we tell you what to expect.
Generac generator gas pipe sizing chart
A Generac generator gas pipe sizing chart ties pipe size to the generator rating and the length of the run. We size the line for the unit, the distance from the meter and the other gas appliances in the home, and the gas utility may have to confirm the meter can supply enough. This is work for a licensed professional, not a chart you follow alone.
Generac generator installation video, quick start guide and tune up kit
A Generac generator installation video can show the idea, but your site decides the details. A Generac generator quick start guide helps you use the controller after install, and we go through it with you. A Generac generator tune up kit has the parts, but our technicians do the tune-up for you during maintenance.
