We had such a great experience with Landry Mechanical! Our mini splits hadn’t been working properly and they were able to come out quickly, troubleshoot the issue, and actually take the time to explain what was going on and how our system works. They were responsive, kind, and so easy to work with.

We also have a garbage disposal issue we need taken care of, and I love that they can help with that too. It’s honestly refreshing to find a company that can be a one-stop shop for so many things around the house.

Being in real estate, I’m always looking for reliable people I feel comfortable recommending to my clients, and Landry Mechanical is definitely going on my referral list!

Huge thank you!

I had a fantastic experience with Sam and Nick from Landry Mechanical Inc Plumbing HVAC & Electrical. 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!

I had an odd job to fix a bathroom fan installation that was not venting properly to the available outside ducting when the bathroom fan was changed as part of a bath remodel. It had been vented to the outside several years ago as part of a Mass Save house insulation upgrade project. Through the Angie website, they recommended Landry Mechanical and they took the job, communicated well, scheduled a visit within two days, and fixed the problem! Mike pulled out the fan and connected it correctly to the ducting. I mentioned about checking if it's now really venting to the outside like it should. He offered to take a look at where it vents outside to see if the louvers were open when the fan is running and they barely were. Wondering if the ducting was even connected correctly, Mike then went into the attic to take a look at the ducting, which was underneath cellulose insulation we had blown in as part of a Mass Save insulation job a few years ago. He said there were bends in the ducting that would cause resistance free to air flow, so not ideal. He didn't have the proper tools for doing rigid ducting work (as his specialty is electrical), but said he'd check with the HVAC part of the company to see if there's anything they could do, so waiting on that, but I was happy just to get someone in who's willing to do that kind of job when it doesn't fit neatly into the company's specific areas of expertise and the price was quite reasonable and took the time to answer all my questions and made sure I was satisfied! I am considering changing to using them for their AC/Heat/Plumbing/Electrical annual service program when my exiting contract with another company expires.
