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.

Evan from Landry Mechanical came last week to do our yearly heating plant review. He explained what he was doing as he proceeded, and completed review and, happy to say, everything was fine.

Update Aug 22, 2026:

We had three separate services completed yesterday and, as we've now come to expect from Landry, every technician was professional, knowledgeable, and courteous. Eddy Russell handled our HVAC maintenance and did a thorough job, explaining what he was doing along the way, adjusting his work order a bit, and completing the job in a timely fashion. Jose Viveiros took care of our plumbing service efficiently, fixed two issues he discovered (Kitchen sink & Bathroom shower), and left everything clean and in great shape. Jonathan Torres installed two mini-split dongles and he and his teammate were prompt, detail-oriented, and made sure everything was working properly before they left. Great communication, quality work, and a smooth experience overall. The only issue I have with to report is not related to the work that was done, but rather the fact that it took many many months for the dongles to be installed. I would have expected some kind of consideration for the prolonged delay. Having said that, I do highly recommend Landry Mechanical.

We engaged with Landry Mechanical and several other HVAC providers in November ‘22 to get bids to replace our aging AC system. The decision to go with Landry was beyond easy, it was a classic no brainer. Between their obvious depth of comprehensive HVAC experience, their knowledge of how to integrate the MASSSAVE incentives into the project, and their commitment to minimizing environmental impact I readily made the decision to leave my long time HVAC provider.

Because of their high value consultative sales approach (Ryan) we ended up contracting with them to replace not just the AC but to install a hybrid ((ductless (mini-split) and duct (heat pump)) system that was completed today under the direction of Jason and with the help of MANY of their team as they worked miracles to complete the install around our hectic holiday schedule. And to top it off, they have guided us through the MASSSAVE process every step of the way so that our actual out of pocket expenses are in part subsidized and part financed at 0%.

In short, without question they have exceeded all my unreasonable expectations from the point of initial engagement to the installation itself. Great team, great customer sensitivity, and now we are fully expecting great reduction in our environmental imprint.

My tankless hot water heat exchanger corroded and failed, called Landry for repair, Landry sent the technician on the same day. Technicians came on time and looked into the issue and worked with manufacturer to get the part overnight shipped under warranty, came next day and replaced the part. Great service.

It starts with the professionalism and courtesy from Anthony and Nick. Not only did they do a great job, but they clean any mess they make. (I know that sounds simple, but you’d be surprised how many contractors miss this point) They kept the noise down to a bare minimum out of respect for my neighbors. They also were working to complete the job from the minute. They came in till the minute they left. Very impressive

The installation crew for a water heater and water tank arrived today. They explained everything they were going to do and answered all my questions. The work was very well done and the duo that completed it were helpful, friendly, and extremely competent. This is the second time I have used Landry's. I highly recommend them. I will certainly use them again.

Drew was excellent. He was timely, polite and very knowledgeable. He identified our problem which was atypical with his thorough examination. Even gave us a plan B if the issue should happen again. We greatly appreciated his expertise as well as his teaching. We will definitely be keeping Landry as our provider of choice for HVAC service and products.
