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.

Wonderful experience with Landry from start to finish. Scheduling was easy, reminders were helpful (& not overwhelming). Rosalie was professional, knowledgeable, friendly & courteous. She explained everything post service, gave me some education/advice/options and did so without making me feel like she was trying to sell. One of the best tech experiences I’ve had in 30ish yrs. 10s across the board!

The technicians replaced my gas water heater and related plumbing. They initially provided several estimates, based on the equipment to be updated. Once I chose an estimate, they kept me updated about the installation progress. They were both professional and congenital and stayed to insure everything was working properly throughout the house. This was my first time using Landry but it won't be my last!

Prompt arrival and quick remediation. My outdoor hose was fused to spout. Provided options that helped me decide course of action based on cost and outcome. Provide advice for how to prevent future problems. Brass on brass/don’t forget to remove hose before winter. I would recommend Landry Mechanical and Plumbing to friends.

Ivan came to my house to do my fall maintenance service. You can't ask for a better person! He explained everything he was doing as he did it. Felt more at ease with him testing the part of the systems he was checking, knowing the values that the systems need to run at, and making sure they are working.

I will be asking for him from now on to service my system.

What did I pay? I pay $20 a month for a service contract and get 2 maintenance checkups, per year, free. Also an emergency call is a flat fee of $299 or $399 each call (Can't remember which one it was). If you have the contract, you pay $99 for the call, plus whatever work and parts they need.

Great company as long as they have people like Ivan. I only gave him 5 stars because i was prevented from giving him 10 stars.

Working with Landry was very easy. I most appreciate that they send a picture of the technicians, along with a background check clearance before anyone comes to the house. Friendly, professional, and thorough. Cost is given up front with no surprises.

I had a leaking connection on my water heater. The technician came and assessed and gave me options to repair or replace but said I could probably get a few more years out of the tank. He provided 3 quotes. Repair only. Replace with new tank. Replace with a tankless water heater. No push to go with. Full replacement which I appreciated. Friendly, professional, respect for my property. All things I look for.
