He finally solved the issue -- a problem so rare that even my HVAC‑specialist friend couldn't diagnose it. I'm truly grateful for the outstanding work David did. He was a real life‑saver. And just a note: if he doesn't pick up your call right away, don't worry. It simply means he's busy, and you can trust that he will always keep his promises, fix the problem, and make sure your home stays warm and comfortable.

Ruh-rohhhh.The motor on our air handler died in August. It was only a 89 degree day, and a super…read morehot week. We come to find out the system is around 35 years old. It's old enough to have a family, a career, a mortgage... Uhh. Time for a replacement. After speaking to 7 companies and getting 3 quotes, I landed on Nick's company. Almost immediately after reaching out, he was asking questions, requesting pictures, and really trying to get an idea of my space. He was kind, thoughtful, and extremely communicative. Unlike one company I dealt with, he was also open to giving me multiple options. There were no pushy sales tactics. He definitely isn't a salesman, he's an installer. Replacing your entire HVAC system is not cheap, and honestly, it is intimidating if you don't know a darn thing about SEER ratings and tonnage. I can research just about anything, so I really appreciated being given the information and having the opportunity to take it back and analyze it for myself and compare. The entire install went great, the team was courteous, respectful and seem to work well with Nick! They were joking around like old friends while working their tails off getting the install done. FYI he is not located on long Island any more, but that doesn't stop him from providing excellent service. He is on the island all the time. We're extremely happy with everything so far and we couldn't have picked a nicer person to do it with. Ps: if you need further proof that he's an all around great guy, he loves animals, too!!

Absolutely amazing overall! My AC stopped working, and instead of immediately trying to charge me…read morefor a service call, Nick took the time to troubleshoot the issue with me over the phone. He figured out exactly what was wrong, told me which motor to purchase, replace the capacitor and patiently explained how to replace both and get everything working again all without ever having to come to my house. He was extremely knowledgeable, honest, patient, and genuinely cared about helping me. It's rare to find someone who provides this level of customer service and doesn't try to take advantage of you. I highly recommend him to anyone who needs AC repair. Nick definitely knows his stuff and will be the first person I call for any future HVAC issues or new purchases!

I reached out anyway because of the great reviews. I sent a message and did not hear back from them. I sent a follow-up message checking to see if they got my message and if they could test my system that week to find what the issue is. I received a text back that said "no sorry yes," and nothing else. I messaged back saying " great," when can you come by? I never heard back from them. Many companies pay for positive reviews nowadays, and I believe that's what this company is doing. Use someone else.

Kevin dispatched Paul and his team to remove, clean (off-site because our building required it), and re-install our PTAC units, and I could not be happier.

The units are now squeaky clean; I don't hear a sound! The price was reasonable and honest. I'm happy I found a trustworthy, thorough and meticulous company to care for our PTAC needs.

We were doing renovation on our house and wanted to put in central air. I was told to contact Stan…read moreGelber and Sons by a friend that uses them. They came out, went over options and they figured out it was going to be too expensive to put in a new central air. They recommended ductless units. We decided to go with that for air and primary heat. Their crew came to install early on the morning we were scheduled. They werr friendly, efficient and cleaned as they went. At my wife's insurance, they made sure all the outside piping was kept as close to the molding and base of the house as possible. They did a beautiful install. They came back when my wife was unhappy with one of the units not being level. They adjusted it the way she wanted. Turns out our house is not entirely level. They had to come out one more time. It seemed that the fan for my chimney wasn't working. Our electrician traced the line and the power ended at one of the units. He said that the line probably got cut during install. I called Staj Gelber & Sons to let them know. They said that they didn't think they could have done it but would come out to make sure. They met my electrician, had to drain the unit of refrigerant, take the unit off of the wall and wait while the electrician checked. It turned out that the wife was indeed cut during install. It had been buried in the wall and inside spray insulation so the crew couldn't have really known. After the repair, the crew put the unit back on the wall, filled the condenser up with refrigerant, tested all the units attached to that condenser and they cleaned up everything. I am incredibly pleased with how the units work and the service we have received from everyone at Stan Gelber & Sons.
