Generator Repair in New Orleans — Don’t Get Caught Without Power

When a Louisiana storm knocks out the grid, the difference between a house that keeps running and a house that goes dark is a generator that actually works when you need it. If yours is not starting, is not transferring power, or is throwing a fault code you do not understand, Rob’s Air has fixed it before. We are your neighbors in Harvey, and we have been keeping New Orleans homes powered for 35+ years.

Fast, Dependable Generator Repair for New Orleans Residents

Louisiana weather does not wait for a convenient time to knock out the power. Hurricane season brings outages that can last hours or days, and a standby generator that fails right when you need it is not just an inconvenience. It is a real risk for your family, your food, your medical equipment, and your home.

Rob’s Air technicians repair whole-home standby generators and portable units across the New Orleans metro area, including Harvey, Metairie, Kenner, Chalmette, and the Westbank. We are licensed, we know Louisiana’s climate and the way it wears down equipment, and we show up ready to diagnose the real problem instead of guessing.

Same-day service is available for most generator repair calls. We know how it feels to sit through a summer afternoon with no air conditioning or a stretch of stormy nights with no lights, so we move quickly to get your system back online.

Common Generator Problems We Fix in Louisiana

Generators in New Orleans work harder than most, between the heat, the humidity, and the salt air near the Westbank and the river. Here is what we see most often on service calls:

Failure to start. Often a dead battery, a worn starter, or a fuel delivery issue. Plain English: the generator’s starter motor works like the starter in your car. If it wears out, the engine will not turn over.

No power transfer. The automatic transfer switch is the part that moves your home from utility power to generator power. When it fails to engage correctly, your home stays dark even though the generator is running.

Fuel system problems. Old fuel, a clogged fuel filter, or a fuel line issue can keep the engine from running smoothly, or from starting at all.

Battery and charging issues. A generator’s battery charger keeps the starting battery topped off between uses. If that charger fails, the battery can go dead right when a storm hits and you need it most.

Control board and sensor faults. Modern generators run on a control board that monitors the engine. When a sensor sends bad data, the unit can shut itself down or refuse to start, even if the engine is fine.

Exercise cycle failures. Most standby generators run a short self-test on a set schedule. If that test fails quietly, homeowners often do not find out their generator is not working until the power actually goes out.

Whatever the cause, our technicians walk you through what they find in plain language, what it means for your system, and what it will take to fix it.

Why Is My Generator Not Starting? Troubleshooting Tips

Before you call, there are a few things worth checking that can save you a service visit.

Check the switch position. Make sure the generator is actually set to Auto and not Off or Manual. It sounds simple, but it is one of the most common reasons a generator sits quiet during an outage.

Look at the fuel supply. Whether your unit runs on natural gas, propane, or diesel, confirm the supply valve is open and the tank or line has fuel.

Check the battery. A generator’s starting battery is a small 12-volt battery, similar to a car battery. If it is more than two to three years old, it may be time to replace it.

Look for a fault light. Most control panels show a code or a blinking light when something is wrong. Note what you see. It helps our technicians diagnose the issue faster, whether over the phone or on-site.

Listen for the exercise cycle. If your generator has not run its scheduled self-test recently, that is a sign something may already be wrong.

If you have checked these and your generator still is not starting, it is time to call in a licensed technician. Some issues, especially anything involving the transfer switch or the electrical connection to your home, are not safe for homeowners to troubleshoot on their own.

FAQ

Why is my generator not starting when the power goes out?

The most common causes are a dead or aging battery, the switch being set to Off or Manual instead of Auto, or a fuel supply issue. If you have checked those and it still will not start, give us a call and we will get a technician out for same-day service in most cases.

How much does generator repair cost?

It depends on what is actually wrong, whether it is a battery, a transfer switch, a fuel issue, or something with the control board. We will diagnose the problem first and walk you through what it will take to fix it before any work begins.

Do you repair all types of generators?

We repair whole-home standby generators and portable units for homeowners across New Orleans, Harvey, Metairie, Kenner, Chalmette, and the Westbank. Give us a call with your generator’s details and we will let you know how we can help.

How often should I have my generator serviced so it does not fail during a storm?

Most standby generators should be checked at least once a year, ideally before hurricane season. Regular maintenance catches battery, fuel, and sensor issues before they turn into a no-start situation when you need power most.

What is a transfer switch and why does it matter?

The transfer switch is the part that automatically moves your home from utility power to generator power during an outage. If it fails, your generator can be running fine and your house will still stay dark. It is one of the most common repair calls we get.

Do you offer same-day generator repair in New Orleans?

In most cases, yes. We know a generator problem does not wait for a convenient time, so we prioritize same-day service for generator repair calls across the New Orleans metro area.
