Signs Your Generator Needs Repairs

Generators often give subtle warnings before a major breakdown occurs. You might notice slow startups, inconsistent power output, unusual noises, or even a burning smell near the unit. Other signs include visible corrosion, fuel leaks, or the generator struggling to stay on during operation. These issues can signal worn components, clogged filters, or electrical malfunctions. If you notice any of these warning signs, scheduling prompt service with Landry can prevent larger problems and ensure your system is ready when the next outage hits.

Common Generator Issues We Repair

Generators are complex systems with mechanical, electrical, and fuel components that must work together perfectly to deliver consistent power. Landry Mechanical Inc Plumbing HVAC & Electric provides complete generator repair services to restore safe and reliable operation. Our team handles all types of generator problems with precision and care to ensure dependable performance in every season.

Engine and Motor Repairs

If your generator struggles to start or runs unevenly, the issue may lie in the motor or engine. We clean, tune, and repair engines to improve performance, prevent stalling, and ensure smooth operation during extended use.

Fuel and Oil System Repairs

Fuel contamination, leaks, or low oil pressure can lead to major system failures. Our electricians and technicians inspect lines, filters, and tanks to restore proper flow and prevent future damage.

Electrical Component and Wiring Repairs

Faulty wiring, damaged control boards, or corroded connections can cause power interruptions or complete system shutdowns. We test and repair these components to ensure your generator delivers stable, safe power output.

Automatic Transfer Switch Testing

The transfer switch controls when your generator activates during a power outage. We inspect and test this mechanism to confirm it engages seamlessly when needed, keeping your home powered without delay.

Samyson was an absolute superstar - after being without hot water for a few days, he swooped in to save the day (and wouldn't quit when faced with a bit of rust/bolts that refused to budge!) Highly recommended and our dogs loved that he would throw a ball for them anytime he had to go back to his van

I recently had some electrical work done, as well as all of the smoke detectors. Everything went well, then a few weeks later they started going off on the second floor. I called and they sent someone right away. It was a defective alarm. Thank you Landry for sending someone right away.

5 stars to Landry Mechanical. The scheduler got me setup for service next day. I received a text message confirming I was on the schedule the morning of service. Then they sent me photos of the electricians with verified background checks that would be servicing my exhaust fan issue. Mike Dowd and Nick Chappelle were FANTASTIC and resolved my electrical issue and set me up with a new Panasonic bathroom exhaust fan which is much quieter and brighter. Mike and Nick were timely, professional, friendly and very helpful in resolving my problem and answering my questions. Great experience with Landry - thank you!

Had an issue with our water heater on Easter. The tech, Jose, arrived in a timely manner and was professional and courteous, and the issue was resolved quickly and we were provided with various estimates and options for moving forward with dealing with the old water heater. Would definitely recommend.

I had an emergency with my shower pipe coming from behind the wall which corroded at the fittings and it blew the shower head off the wall spewing water everywhere. I turned water off and called Landry. They came immediately the next day and told me via text on arrival time. The technician was absolutely pleasant to talk to and his service was perfection 🥰 I will be calling again for upstairs apartment as soon as possible.
