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.

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.

Aaron from Landry was friendly and informative, and much less pressure than Heritage. He gave a second opinion on my furnace at no cost.

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.

I had a fantastic experience with Sam and Nick from Landry. Both were highly professional electricians who went above and beyond.

They took the time to clearly explain the safety benefits of arc fault breakers, which was incredibly helpful. Their expertise was proven almost immediately when one of the new breakers tripped, signaling a real issue in my home's wiring. Sam and Nick quickly troubleshot the problem, identified some poor workmanship from a previous contractor, and fixed it on the spot. Once repaired, the breaker worked perfectly.

They also moved an outlet over to another wall for me and did a beautiful, seamless job. I highly recommend Landry Mechanical, and specifically Sam and Nick, for any electrical needs in the Worcester area!

We came home from vacation to find that our hot water heater had died and was leaking all over our utility room. I called up Landry, and they had a technician come out within about an hour, and we had a new hot water heater a few hours later! They were extremely professional and thorough, and left our house clean. We will definitely use them again!

They are experienced in what they do, but I wish they would do something about how you call on. I spent 10 mins try to get to talk someone live that could help.

Landry have done absolutely outstanding work again. I've written prior positive reviews, so I won't go into detail here. Landry replaced two large pressure tanks in our water treatment system. In summary: Extremely pleasant trustworthy reliable workers. This time they threw in replacement of a leaking water intake pipe - copper with brass fittings - for free.

Landry Mechanical just wrapped up the installation of a heat pump at my home. Normally, I’m not a testimonial giver, but I was so pleased with the team who came and the service I received that I felt compelled to do it this time. Wonderful transparency throughout the entire process – – from assistance with paperwork through scheduling, and then through the installation itself…. And then, before they left, ensuring I was comfortable with the equipment, including how to use the new thermostat.

The entire time the crew was on site, they were incredibly focused on delivering a quality product along with a quality installation, and took great care to ensure they kept our home clean of debris, both inside and out.

I’m not planning on a second heat pump for the other zone in my house, but if the need does arise, I know I will be calling Landry Mechanical again.

I had technicians Nick and Ricky at my house today to install hot water heater. These gentlemen are first class, extremely courteous, very nice to work with. And in my 130 year old house they were thrown curveball after curveball and knocked it out of the park every time. These guys did a great job.I recommend Landry Mechanical any day of the week.

Landry helped to resolve a problem with my boiler quickly. The initial evaluation showed the new boiler was working fine but lacked the electrical connected needed to fire up. Thankfully, Landry offers electrical services too so another tech was able to quickly wire a new connection and get us fired up in time for the cold. Thanks for the great service! Both technicians were friendly and knowledgeable
