They're really knowledgeable and the work was done quickly. I also asked if they could take a look at some outlets in my house that were acting up. Thank God they did! Looks like some of the wiring wasn't done properly so they went ahead and sorted everything out for me. I can't say enough about how professional, knowledgable, clean and tidy and efficient these guys are. I already asked them to quote me on some other stuff! Their price was very reasonable and I would honestly have paid twice as much for what they did.

Mike and his team are some of the most talented plumbing and heating experts on the island…read more After moving into our new house 2 years ago (north shore of LI), we recognized we had a very extensive and complicated boiler room (not to mention quite a lot of bathrooms) that was giving us some problems. We had consulted with a few plumbing companies in the area, including some of the bigger ones, and none were really able to grasp the complications of our boiler system. We finally contacted Mike and Matt, and they were able to coherently explain what was going on and what all of the issues were. When we eventually ran into bigger problems with our wall boilers (a result of the prior owners not taking any care of them for a decade), Tumminello was our choice to revamp the entire boiler room with brand new equipment. They are truly experts at their craft (a lot of the technical aspects go over my head). Mike, Matt and their guys did such a great job and we're super happy with out it turned out. They always showed up on time and didn't leave until the job was done. Our boiler room is now much more efficient and organized and, most importantly, in working order (shoutout to Matt in particular for being a rockstar - he could be a rocket scientist for NASA; he also took the care to make sure everything looked perfect and was super organized). We've also used Tumminello for non-boiler-related issues (e.g., sink installation, leaks, clogs, etc.) and they've always responded promptly (and fairly). Truly a one-stop shop for all things plumbing and heating. Do not hesitate to use Tumminello. Very, very highly recommended!

Every year when we go to test the heat, it doesn't work. And have had a few other issues in between. Last year they came to fix another problem and charged a ridiculous amount of money, and a few hours later the problem started happening again. I called a friend who's a plumber and he fixed it for $100. Company is a rip off and the owner is awful.

Although it took some time to find a competent installation electrician, once I did, it was a breeze. Seriously - this company sent over electricians within hours (not days), had the best price, a very fast install, and incredibly kind electricians. (I was about to invite them in for a beer!). The bill I got was EXACTLY the same as the original quote. Not a dollar extra. This is super rare in my experience. Truly a 10/10 experience. If you need a Tesla charger installed, or probably any electrical work, this is your team.

I will break it down. 11/2024 the came and replaced a transformer on a buzzing heating unit of which I paid $150 for them to come and evaluate earlier. No bill was issue and I was asked to call the office. The same day they confirmed this fee would be applied to the invoice via phone. An invoice was never received so I figured there was no bill. The transformer is $100 online. I contracted with them to do further work for roughly $2,300. Bill was paid the same day. 3/2025 they issued a bill for $430 for 15 minutes of work. Ok but they did not remove the $150 evaluation fee they charge to just come out though they said they would. I responded immediately to the email asking why it took so long for them to invoice and to remove the $150 as the office promised. No response was received. 4/2025 they sent me to collections for this bill. The company is unprofessional in their communication and I would not recommend them though they did decent work. All they had to do was email back or call regarding the invoice.
