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.

Matt Stagliola was fabulous. We still have a clogged drain, but Matt was so thoughtful and methodical in his approach. Very professional, personable, knowledgeable and polite. He explained everything he was going to do. He gave us multiple options, but advised less invasive options before more expensive and aggressive fixes.

Landry completed a project where they converted my oil burner heat and hot water system to heat pump and electric water heat installation. In one week they had a team of people come in to remove oil tank and furnace, install the mini-splits, and the water heater. Extremely efficient and we did in winter time and I lost heat and hot water for maybe 4 hours. Everything was organized and completed on time and on schedule. Sammy was excellent and made sure all the line out were well covered and the mini-splits were placed in areas where they were less noticing. Landry worked with mass save to get me the rebates and the salesman Tim was very helpful answered a lot of questions. Prices were very competitive I had several quotes and the mini-splits were less expensive but Landry was the only one that could remove the tank , install heat pump and water heater. They exceeded my expectations and was very smooth transition. Repaired the hole where the boiler exhaust was and ensured any openings to the outside was sealed. They left a small area of drywall opening but that is typical of most plumbers. The opening was in the garage to access the plumbing and they covered with wood.

Their customer service is great that’s why I went with them. They’re a bit overpriced and they do not accept military / Law-enforcement discount. I also asked for $500 off because I seen a coupon online and they said it was only for water purification systems. I didn’t fight them on this and I paid a little more than 12,000 for a replacement HVAC system.

Both Joe Viveiros and Corey Menard were fabulous. We have no issues at all with the service provided, and are greatful to have heat today. We do feel that your communication system is highly flawed. On our 5th day with no heat, we made three calls 2 hours apart between each call, and did not receive any calls back until my husband finally called and spoke to Gabby directly (who was excellent). All we wanted was a status update. We were not asking for an appointment time. We wanted to know if parts had been ordered and if so when they were expected in. I don't know if your answering service is actually staffed by Landry, but receive zero communication almost made us call Garabedian instead. Your actual technitains were great. Your communication was horrible.
