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.

Very professional very nice took the time to replace an item in my bathroom sink didn’t charge me for it also helped me with a device that was attached to my washing machine that needed to be detached which they didn’t hesitate to help me with, but the biggest thing was when they came into the house And handed me my brother’s wallet that had cash in it. They found it on my driveway You can’t get more trustworthy than that

Jorge Gonzales from Landry arrived on time today to check out the faucet in my shower. I was not getting enough hot water but all other faucets were fine. He quickly found that the rubber gasket on the cartridge had deteriorated, replaced it, and left my shower as clean as he found it. Jorge was courteous, friendly and professional. I would not hesitate to have him come and do additional work for me. Landry is lucky to have him!

I cannot say enough how happy I am for choosing Landry. Sam Reynolds and Josh Clough came out one day to look at an electrical repair, gave me an estimate then came back the next day to do the repair. Sam and Josh worked in 15 degrees weather, did a great job, frendly and accommodating, I would recommend them to anyone. Thank Mike Massauro

Outstanding Service!! Our company had a main drain clog, and it was important that we get the line open so we could use the building. Within 1 hr. they had a team over lead by Matt S. and he walked us through the entire process. We even got to look through the pipe camera to see the condition of the pipe after it was cleared. And no, it did not cost us an arm and a leg! Considering the quick service, not losing down time from work and the work they did, it was reasonable. We would highly recommend them and will use them in the future. The staff at Gurney Water Treatment, Sutton MA.

What I like about Landry Mechanical: 1. They have dedicated staff to take your call or you can book online. They are VERY proactive about calling you back. 2. Both times I used them they booked me quickly. 3. They actually show up when they say they are going to and send you a photo of the person coming, which is nice for security reasons. 4. They do good work! My last technician was so personable as well! UPDATE: I'm now on my third visit from them. I have an old house with old plumbing. My review is the same - a very positive experience. They are responsive and fit you in!

Another great experience with Landry Mechanical. I use them for plumbing, HVAC and electrical needs, and they are always fast to respond and exceptionally professional. Today I had some plumbing done on an emergency basis based on a leaking toilet that was flowing from an upstairs bathroom down to the lower floor. Randy Kyle showed up on Sunday afternoon and quickly assessed the situation and within a few hours had a new toilet installed, a new shut off valve and left the entire bathroom area spotless and ready to go! Thank you, Randy you are a Wonderful brand ambassador for Landry Mechanical, and I hope I am fortunate enough to have you back in my home for any future plumbing needs!
