Excellent experience with Landry’s Mechanical!
Bill did an outstanding job with my EV charger installation. From the beginning, he was friendly, professional, and took the time to clearly explain the quote and the work that needed to be done. The price was very fair, and there were no surprises.

The installation was completed quickly, and the workmanship was excellent. Everything was done perfectly, and I couldn’t be happier with the finished installation. Bill made the entire process easy and stress-free.

I’m extremely happy with the work and would absolutely recommend Bill and Landry’s Mechanical to anyone looking for quality electrical work.

I had a fantastic experience with these guys. The entire team was incredibly friendly and professional from Tim, the person who came out to give my quote, to Julian and Marcus and the rest of the team who did the work. They were very kind, professional, patient in educating me and accommodating my specific requests, and they were all super respectful of me and my home during the job. The units themselves have transformed my home with their quiet and efficient cooling. Thank you so much to the whole team at Landry!

Fantastic experience. Propane furnace install be another company a couple years ago. Went thru 3 igniters in the last year and was serviced by techs that were obviously not trained on this unit. Contacted Landry and a tech named Louis showed up. Went right at the unit, located the actual problem that was issue and solved it within a day, including getting a new heat exchanger from Hartford. No issues since and the whole house now has more hot water than ever due to the crud in the old unit. VERY HAPPY with Landry. Cudos to Louis !!

Very professional, honest, and quick. We replaced our 26 year old AC unit with a Heat Pump and new condenser. Landry was very professional but their quote was a little higher than some others that I had. But when I drilled into everything that Landry was including, that the other companies were not the price was spot-on. I just felt more comfortable doing business with Landry. The installers were very knowledgeable and I loved that the office sends you an email with the installers photo and names in advance. This is more than just a "nice" email, it's peace of mind knowing who is coming into your home. From the day I had my initial quote from Ed to when installers Garret, Kyle, and Dimitri completed the job was a span of 9 days. And Ed was very helpful in helping do the MassSave Heat loan. Many thanks Landry team!

If I could give Landry Mechanical 10 stars I would have. Always great service at a great price. Jose and Jack came by today and did the annual water heater flush. Also, they took time to answer my questions as all their technicians do when the job was completed. Thanks for all you guys do :)

I had Landry install a washer/dryer power and plumbing upstairs in my house. The craftspeople were knowledgeable and thorough and cleaned up well. I think it was a bit more expensive than it could have been but the job was well done. I've also used them for my HVAC service - they're very thorough and professional, and scheduling service is easy, I think because they're a big company. Again, I think they're probably somewhat more expensive than average but the service is worth it to me.

She did a checkup on our air conditioning unit and it was done well and it was a good report. Very thankful for the work that Landry and company do!

If there was a 10 star I would give it. Joe and Jack were absolutely fantastic. They arrived by 8, were done by a little after 9 and my new toilet looks fabulous. The bathroom is as clean as I left it. They took the old toilet away too. Couldn't be more impressed with these tradesmen. Thank you Gentle men!!
