I have been a customer of Stan Gelber and Sons for many years. While I have no complaints about their technical expertise, their aggressive billing practices have been disappointing. Last year, my boiler (installed by Stan Gelber about 5-6 years ago) started overheating. They quoted me for an Aquasmart well and sensor replacement. When the technician arrived, he replaced only the temperature sensor, which took about 5 minutes, but not the well. The technician was unprofessional, appeared annoyed, and gave curt responses when I asked what was done. I refused to pay for the well replacement that wasn’t completed, and they provided a new quote that I paid in full. Despite this resolution, I’ve since been harassed with calls and letters from collectors. This experience has left me questioning their customer service and billing practices, and it’s a shame because their technical work has always been reliable.

We recently used Stan Gelber & Sons for a seasonal furnace check up and for installation of a new all house humidifier. Everyone who came to the house was polite and professional. Work to be done and work that was done was explained thoroughly. Attention was paid to keep our house clean during work. We worked with Mike Connor and Jose Zelaya for the humidifier installation. Our only concerns were with the phone system. It was difficult to get through to the office at times, and it seems there are various departments or people involved rather than a centralized office like we have seen with other companies.

Jose Castro was a friendly and knowledgeable technician. He diagnosed a an inducer assembly issue. Gelber ordered the needed part. They scheduled an appointment to have him install the part today. He arrived timely. He installed the part quickly. Thank you Jose Castro and Stan Gelber. Problem solved.

I just had an amazing experience with a whole house heat pump installation. Everyone from the salesman, Tony to Jose Zelaya, Miguel Salgado, and the rest of the crew was punctual courteous, and respectful of my time and property. Full disclosure, there was a delay on one of the units, but it was installed on the next business day. The electricians they sub-contracted (Progressive?) were pleasant and competent, but they left the fence open, the old panel behind, and nails in the driveway. I don't even know when they left. I am pleased with the work. The installation is excellent, and I would recommend them.

Not liking the company take-over. Still w/o heat, waiting on a resolution. Stan installed the unit.

Stan Gelber & Sons just installed a new heating system and everything worked out great. Mike Connor was a pleasure to deal with. I would definitely recommend them.

We had a scheduled appointment for 1 PM - 5 PM and at 4:15 they call and tell us that they are not coming because their technician got held up on another job. They offer another appointment, but it has to be in the same four-hour window which is completely ridiculous when you have already wasted four hours on another day. Not the same company since the Gelber Family sold it. Beyond disappointing. If I could give them 0 Stars I would.

I had water damage to my basement when Long Island had the massive rainfall at the end of August 2024. My oil tank line snapped and there was damage to my boiler (including hot water heater) and oil tank. After a month without hot water, we received a lot of estimates and different proposals, but ultimately, we chose Stanley Gelber and Sons. The reason I chose Stan Gelber was the “salesperson” Michael Connor. Michael isn’t a salesperson, he is an expert in HVAC, I should say the leading HVAC expert in the NY area! Changing from an oil heating system is a major change and I had alot of questions and did a lot of research. Michael always answered his phone and gave technical knowledge whenever I asked. He outworked the competition and made educated suggestions based on my HVAC system and family needs. If it wasn't for Michael, I may have chosen another company. His insight, expertise, and reliability were the key factors in choosing Gelber. Knowing the condition of my Boiler, and also the age of my Central Air Conditioning system we decided together that a Heat Pump system was the most efficient way to go. I could have saved a few dollars in the short term on a straight replacement of the oil burner and tank, but after taking everything into consideration the heat pump system (heat pump unit, heat pump hot water heater) and a mini split in the basement would be the best investment for our house. Michael helped with the financing aspect. The financing was very reasonable, and we scheduled the installation. My attic was a mess, and I wound up putting down some new flooring and threw out some old stuff to make the job easier for the Gelber crew. The coordination of the installation went super smooth.It included the removal of the oil tank with oil inside, the oil burner, and scheduling the electrician. I do most of my own work (cutting lawn, carpentry, electric, painting, etc.) and really don’t like a lot of people coming into the home. That changed quickly! The Stan Gelber crew was amazing. They totally transformed my home! The crew led by Oscar was clean, neat, and friendly. They put drop cloths everywhere, and always vacuumed the house upon leaving. Oscar and the guys went above and beyond what was in the contract because they wanted the system to work correctly. I have a long ranch, with a huge attic and the positioning and planning they did has made it go from a junk attic to a major selling feature if I do ever sell. I think Stan Gelber increased the value of my home by 100K, no joke. I can’t thank them enough, Nobody works like this anymore! The new unit outside (Bosch condenser) is the best in the industry. The Rheem heat pump hot water heater is so efficient. And the Lennox AC/Heat mini split unit in the basement pumps heat so quickly! All of Michael’s suggestions paid off. When the job was complete, I figured the process was over, it wasn’t. Michael came back to inspect and has also helped tremendously in working with PSEG to make sure that I receive my full home energy rebate. And it’s a nice rebate!! Stanley Gelber and Sons is amazing. I can’t thank them enough. I don’t do reviews, but the job they did from start to finish has changed my whole home and made it super-efficient. They are the best!

We recently upgraded our 25-year old central AC to a ductless mini-split system, and we couldn’t be happier! The entire team at Stan Gelber & Sons was fantastic to work with. Our sales representative, Mike Connor, was incredibly professional and was always available to address any questions or concerns we had. During the installation, Kevin and his crew did an outstanding job removing the old system and installing the new one, all while treating our home with care and keeping everything tidy. I’m really glad I chose Stan Gelber & Sons, and I will definitely be using their services again in the future!
