Heating & Air Conditioning / HVAC near Syosset

“My technician Nick was so helpful, endured heat that was totally uncomfortable, in order for me to have a working AC system in the current heatwave we are experiencing. I couldn't have had a better experience with a knowledgeable and very polite rep for the company. Thank you for the excellent service and fair pricing.“

“Have been a customer for 8 years. They are always on time. Always do a thorough job, (from fixing the problem to clean up). Always good communication. My a/c when down yesterday evening. They had it working by noon today! I love these guys❣️“

“Sean did a great job diagnosing the issue with our boiler. He explained everything very thoroughly and answered all of my questions. It was clear he was an expert in the field. Thank you Sean and Tragar for the great service. Our service contract has been more than worth it!!“

“Joanna was great, explained everything well and offered up a lot of different options.“

“Our basement had old, damaged pipes that created a horrible flood and soaked and ruined our whole carpet. The basement was almost like a swamp. This plumber showed up on fairly short notice and ended this catastrophe very quickly. Completely solved our problem and did so quickly. Thank you so much.“

“Very personable and professional service by Mike. Arrived during the stated time period. Wore ‘booties’ when he entered the house, keeping my floors and rugs clean. No nonsense approach. He assessed the situation,offered the solution then priced it out. Gave us an estimate of the time and manpower it would take then asked when we’d like the work done. We said ASAP since it wasn’t an active leak, he could have a crew here in 3 days. We agreed and the job has been scheduled.
Part 2- 3 days later and Mike and Nick showed up on the earlier side of the promised window. Again, entered our house with the booties on. They originally said it would take about 4 hours when they came for the estimate but they wrapped it up in a little less than 2. They replaced a rusted sewer line and several feeds to it that were also rusted. We had just painted the room white and sealed the floor after some minor flooding in the basement. To look at the space, you never would have known they had been there. They had brought drop clothes with them and set those up everywhere. When they were finished, I couldn't find a single spot on the walls or the floor. Super clean workmanship. Theirs is a number we are keeping in our go to repair book. I highly recommend them. I can see why there are so many 5 star reviews. They earn them everyday.“

“I just wanted to thank you for the excellent work you recently completed at my home. Your team was professional, punctual, and efficient from start to finish, and the entire process went smoothly without any issues.

It’s a pleasure to work with a company that takes pride in its work and delivers exactly what was promised. I truly appreciate your effort and attention to detail.

I will gladly recommend your services to others.“

“Extremely professional and knowledgeable. Came on time and did a fantastic job. Andrew and his team were great; very polite and very respectful of our home. I highly recommend this company.“

“River responded to our emergency call same day, fixed the leaky pipe within minutes, and showed us a video clip of the piping system to reassure us no additional fixes were needed. ⭐️“

“Had an oil issue today at my house and Andrew of Oilex was able to help me out in a very professional manner. Oilex delivered to my house an hour before the promised time. Super happy with the entire process with Oilex Fuel of New York.“

“Service persons were friendly and personable. They were very efficient and did the maintenance fast.“

“Excellent service. Quick and efficient dryer vent cleaning. Would definitely recommend and will be using this company again in the future.“

“The service man (Roberto) was very nice and knew his job. We needed to replace the circulator pump in the basement and replaced the thermostat on the second floor. System is up and running.“

“We have used Brian as needed. Not only is he kind, he shows up when he says he going to which that it itself is amazing. We’ve had horrible experiences being put off until another day by repairmen and Brian has never Done that. He is excellent at troubleshooting and then completely the repair. Afterward, everything is put back and you would never know a repair was done. Highly recommended !!!“

“Joe did an exceptional job for us. 5 different companies came and gave us the run around and took our money.

Joe came and spent 3 hours looking at the air handler, thermostat, running to his truck and fixed the unit and we finally have our air conditioning back!“

“Our HVAC didn’t work. A guy came (not from Universe) misdiagnose the issue. We contacted Universe and the service tech came right away within a day (free estimate) to diagnose the issue. Service tech knew exactly what was the issue. Came quickly! Efficient ! Problem resolve within 2 days!! Price is affordable compare to other businesses in Long Island. Highly recommended! Thank you Anthony !“

“I just signed up for Homeserve yesterday, and am still in the ten day waiting period before the contract begins. Due to a poor distribution of heat affecting our main living areas, I called Homeserve this morning to see if they could dispatch someone on an emergency basis before the big storm this weekend. They were so helpful and got a technician in within 3 hours of my call! John was really thorough, kind, and did his best to address the issue. Turns out we have a major airflow problem, and there will be work needed in the future. He was able to quickly diagnose and rectify the problem for the time being. Thank you for coming to the rescue! Before calling homeserve, we had other people whom we had called who either could not make it due to distance and weather, or who made the original problem a bit worse. I am glad I signed up!“

“I highly recommend L. Graziose for AC replacement! Nestor and Chris provided exceptional service with their professionalism and efficiency throughout the entire installation process. Nestor went above and beyond by identifying the root cause of my old AC's failure.

The office staff deserves recognition too - Nicole and Christine were extremely responsive with scheduling and maintained a friendly attitude throughout our interactions.

If you need your AC replaced, L. Graziose Plumbing, Heating & Cooling is definitely the way to go!“

“Awesome company and the staff are even more awesome. From beginning to end Marianne and Brian did an exceptional job. The install was done such professionalism by all. I have personally used them 3 separate times for HVAC needs and have recommended them to several people. If I could give them 10 stars I would!!!!“

“We had a leak coming from the unit, they found the source and fixed it. They were in and out in half an hour, great job! Stephanie is the best!“

“I have been a customer of them for years. They are always reliable. Explain everything that they’re doing. And reasonable in their prices.“

“This past Sunday, during the coldest winter that we’ve had in years, our burner conked out. I have a premium service contract with Slomin’s and they came the next day. They sent a kid who wasn’t sure what the problem was and he said that I probably needed an inducer motor, which would cost me $575. I asked Slomin’s to send an experienced technician but they refused. My son in law, Trio Sheet Metal, recommended Ryan Anthony. A technician came today and found the problem immediately. There was a clog in the inducer. I didn’t need an inducer motor like Slomin’s said. I’m so thankful to Ryan Anthony, not only for their skilled service, but also for their honesty. Thank you.“

“I had a good experience with cool solutions installing a central AC system. Jim and his staff were on time, courteous, and extremely knowledgeable. I highly recommend them.“

“Chris was awesome he came to my father’s house to check his heat, explained everything clearly, was friendly and honest. Highly recommend asking for Chris, thanks again!“

“Manish Patel came to service my system today. He was very Knowledgeable and Professional. Was able to discuss my problem and clearly explain the procees to solve the issue.“

“Mike and his team are some of the most talented plumbing and heating experts on the island. 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!“

“I had a ductless system replaced last year and Joe and his team were a pleasure to work with. The new system works great !“
