UPDATE 11Aug2026:
The Landry team came to my house for the annual plumbing, HVAC, and electric servicing.
Anthony, Randy, and the other person with him (I don't remember his name, sorry) were fantastic - they showed up on time, did thorough reviews of the electric systems and plumbing and gave sound recommendations for improvements and fixes.
Tory performed the HVAC system service and she was amazing. She spent a considerable amount of time checking the system and found leak that needs to be repaired. I cannot recommend this team enough!

Landry Mechanical is the best! We used them to replace our entire HVAC system and we couldn't have asked for a more professional, friendly, knowledgeable, and diligent team. They made sure everything went perfectly from start to finish. Katie is the most incredible point of contact- she patiently answered the multiple questions i had. She also helped me with the Mass Save rebates. The techs who came to our house were polite, friendly, patient, and did a fantastic job installing our system. It’s perfect. Landry will be my "go-to" company from now on. I cannot say enough good things about this company. I highly recommend them!

October 14, 2022 - Landry was once again called to fix broken spigots on the outside of my house. Paul fixed those and also found a pipe that would have burst had he not replaced it when he did. Not only did Paul go above and beyond repairing what I had requested he originally fix, he ALSO found that my dryer vent was incorrectly installed, which would have resulted in my house eventually catching fire. Paul saved my house from both eventually flooding and/or burning down, thus literally saving my family's life. Again, I cannot recommend Paul and Landry enough!

We had one of their electricians, Mike, at our house to figure out why the ceiling fan would go faster while the water kettle was on and how that made the aquarium lights in the next room flicker. Also needed two new 50A circuits installed, a ghost 40A (hot, hidden in a wall) terminated and additional 20A circuits installed in the kitchen. Mike did excellent trouble shooting, fixed the problems and gave us a quote for the whole job same day with work done next day. We have a 1951 industrial install in private residence situation that multiple electricians have simply walked away from. Sometimes you are just grateful that someone is capable, does what it takes and not more and gets it done. Largest part of the quote was wire and parts…

I had Evan Schwartz help with a small problem with my indoor mini split, which was intermittently leaking water all over the wall. He identified the problem, walked me through what it would take to fix it, and got it sorted in under an hour. No more leak! He was a total professional and I will be coming back to Landry again for my other plumbing and HVAC needs in the future!

Evan was fantastic! We couldn’t have asked for a nicer or more professional engineer. He went and beyond in making sure our air conditioning unit was up and running in the sweltering heat! He was a pleasure to work with and very attentive. Thank you

This is the second time I’ve used Landry Mechanical, and both times I have been impressed with the service and with personnel. On this occasion we had a plumbing issue, Randy and Alex arrived two hours after I called, and both were excellent! They found the problem, fixed it right away, and gave me options and cost estimates so I could select what was best for me.

I would give Randy and Alex more than five stars if I could!! I would use them again without a doubt.

I had scheduled a couple of jobs with Landry. Mikey came out and worked on my electrical, and went above and beyond to explain what he was doing and what was needed. Drew came later and was excellent - knowledgeable and patient on HVAC. Later, I had a leak (unrelated and unexpected!) and placed an emergency call to Landry. They dispatched Randy and Ricky, who worked hard to find the source of the leak and fix the problem.
I would not hesitate to use Landry again - each of the techs that came out were professional, knowledgeable, and personable.

Landry Mechanical Associates did an excellent job during my annual maintenance checkup. Jose Viveiros and Anthony were knowledgeable, courteous, and professional. They clearly explained everything they were doing, provided a detailed list of recommended repairs with priorities, and followed up with a thorough summary email that gives me a clear plan moving forward. Thank you!

I had a tremendous experience with my mini splits installation. JT, Marcus, Donny and Dimitri were great. They arrived on time, were friendly, made sure to clean up after themselves and worked very efficiently. JT and Marcus were even kind enough to remove the 3 window AC units for me and bring them down to the basement after the installation of the mini splits was complete. I’ve used Landry for a long time for many different services, and there’s a reason I keep coming back! They always do excellent work.

Owning an older home means repairs are just part of the deal. Over the years, I've called Landry Mechanical several times, and they've consistently done excellent work. Their team is licensed, knowledgeable, professional, and easy to work with.

Most recently, Hunter and Austin replaced a faucet, cleared a couple of slow drains, and installed new kitchen sink baskets. They were efficient, courteous, and did quality work.

If you own an older home, it's worth having a company you can trust. I highly recommend Landry Mechanical.
