24/7 Emergency Generator Repair in Houston
Power out and the generator quit? Call or text 832-418-7218 any hour, any day. A technician will be dispatched to diagnose the failure and get your backup power running again as quickly and safely as possible.
When Your Backup Power Fails at the Worst Moment
Generators are supposed to save the day during an outage, which is exactly why a failure feels like a crisis. The food is warming, the house is heating up, the sump pump has stopped, or a business can’t open its doors. JaWilly Services provides emergency generator repair in Houston around the clock, so when your unit quits you can reach a real person who will send help.
Call or text 832-418-7218. Our team supports residential standby and portable generators as well as commercial and industrial units, and our priority is to restore your power safely while keeping you informed at every step.

What Counts as a Generator Emergency?
If you depend on generator power right now and it isn't available, that's an emergency. Call for 24/7 generator repair when you see any of the following.
- The generator fails to start when utility power goes out
- It shuts down unexpectedly in the middle of an outage
- Strange noises, smoke or burning smells from the unit
- Visible damage, or fuel, oil or coolant leaks
- Alarms or warning lights on the control panel
- The engine runs but the house or building has no power
- Someone at home relies on powered medical equipment
- A business, refrigeration or security system is without backup power
Things that can wait for a weekday appointment: a missed exercise cycle while the grid is up, a maintenance reminder, or a code that cleared itself. Book those through our generator diagnostics service instead.
Stay Safe While You Wait
When a generator failed during a power outage, the urge to improvise is strong. These steps protect your household while a technician is on the way.
Carbon monoxide kills quickly and without warning. It is colorless and odorless. Never run a portable generator inside a home, garage, carport, shed or crawl space — even with doors or windows open. Following U.S. Consumer Product Safety Commission guidance, keep portable units at least 20 feet from the house with the exhaust pointed away from doors, windows and vents. If anyone feels dizzy, nauseous or weak, get to fresh air and call 911.
- Never backfeed. Do not plug a generator into a wall outlet or dryer receptacle. Power can flow back into the utility lines and injure line workers or neighbors. Only connect through a transfer switch or approved interlock.
- Shut it down if something is wrong. If you smell fuel, see smoke or hear grinding, turn the unit off at the controller and keep people away from it.
- Don’t refuel a hot engine. Let a portable generator cool before adding gasoline, and store fuel away from living spaces.
- Keep water away. If the unit sits in standing water after flooding, don’t touch it or try to restart it.
- Prioritize loads. If you’re using a backup source, run refrigerators, medical devices and fans before anything else.
What to Tell Dispatch When You Call
A few details help the technician arrive with the right tools and parts — and often shorten the repair.
- Your address and a call-back numberInclude gate codes or where the generator is located on the property.
- Make, model and fuel typeNatural gas, propane, diesel or gasoline. The data plate is usually on the enclosure.
- What it's doingWon't crank, cranks without starting, starts then stops, or runs with no power to the building.
- Codes and lightsRead any message on the display, or snap a photo and text it.
- Anything that changedRecent flooding, a storm, a freeze or a recent service visit.

What the Technician Does on Arrival
Our emergency response is built around getting you back on power safely — not just restarting the engine and leaving.
Make it safe
The technician checks for fuel leaks, damaged wiring, water intrusion and exhaust hazards before touching the controls.
Diagnose under pressure
Battery, charger, fuel supply, ignition, sensors and the transfer switch are tested to find the actual point of failure.
Repair on the spot
We carry common parts and tools so many fixes — batteries, filters, plugs, connections — can be done on the first visit.
Plan B if needed
When a major part must be ordered, we explain the timeline and explore temporary power options to minimize downtime.
Before leaving, the technician runs the generator, confirms the transfer switch changes over and walks you through what happened. If a component needs to be ordered, our parts replacement team sources an OEM-approved replacement.
Storm Season and Demand Surges
The Atlantic hurricane season runs from June 1 through November 30, and Houston has learned hard lessons about long outages — Winter Storm Uri in February 2021 and Hurricane Beryl in July 2024 both left large parts of the region in the dark. During events like these, every generator that was skipped for maintenance gets tested at once, and calls for after-hours generator service spike across the whole metro.
We work through emergency calls as quickly as conditions allow, but we won’t promise a specific arrival time when roads are flooded or blocked. The best protection is getting your unit inspected and serviced before the season starts. Our hurricane season generator checklist covers what to do in May, not in the middle of a storm.

After the Emergency: Preventing the Next One
Once power is restored, it’s worth asking why the generator failed in the first place. Most emergency calls trace back to a handful of causes: a battery that was already weak, fuel that sat too long, a filter overdue for replacement, or a transfer switch that hadn’t been tested in months. Each of these shows warning signs well before an outage.
A few habits make a repeat call much less likely:
- Let the generator complete its scheduled exercise cycle and pay attention when it doesn’t
- Keep the area around the enclosure clear of plants, debris and stored items
- Book routine maintenance before hurricane season rather than after it
- Have recurring warning lights checked through a diagnostic visit instead of resetting them
- Replace aging batteries and worn parts proactively, before they fail under the stress of a long outage
After a repair, our technician will point out anything else that looked marginal so you can address it on a normal weekday schedule instead of at midnight during the next storm.

Frequently Asked Questions
Do you really answer at night and on weekends?
Yes. Emergency generator support is available 24 hours a day, 7 days a week, including holidays. Call or text 832-418-7218. Routine, non-urgent appointments are scheduled Monday through Friday, 8:00 AM to 5:00 PM.
How fast can a technician get to me?
We dispatch as quickly as we can and aim for a prompt arrival, but we don't promise a specific time. Arrival depends on your location, road and weather conditions, and how many calls are open, which can climb sharply after a hurricane or freeze.
Is it safe to run a portable generator in my garage with the door open?
No. An open garage door does not prevent carbon monoxide from building up, and the gas can drift into the house. Run portable generators outdoors only, far from doors, windows and vents, and use battery-powered CO alarms inside.
Can I plug my generator into a dryer outlet to power the house?
Never. This is called backfeeding and it can send electricity into utility lines, endangering line workers and neighbors and damaging your equipment. A home should only be connected to a generator through a properly installed transfer switch or interlock.
What if my generator can't be fixed on the spot?
Our technicians carry common parts and tools to make on-site repairs whenever possible. If a major part has to be ordered, we will explain the timeline, keep you updated and talk through temporary power options to reduce downtime.
