"Rene and Maurico installed a new air conditioning unit in my home. They negotiated fairly and were responsive to my questions. A team of five arrived for the installation. They worked together like a well tuned machine. Everyone knew what they had to do and when to do it. There were no mistakes. They were here by 8:00 am and were finished by 4:30. They answered all my questioned and responded to my phone calls. They were polite and respectful. They cleaned up after themselves and left nothing damaged. More companies should operate like them. I would highly recommend them"

N H Ross, Inc. is proud to be a locally owned and operated business serving Middle Island and the surrounding community. Since 1971, we’ve been providing expert heating and cooling solutions to keep homes comfortable in every season. From heat pumps and oil-to-gas conversions to new system replacements, mini split installations, and preventative maintenance, we deliver upfront pricing, timely service, and a 100% satisfaction guarantee.

"I have used N.H. Ross in the past, and will continue to use them in the future. They are very professional, extremely well-trained, and knowledgeable in their trades -- As well as genuinely great down-to-earth human beings. Every time I invite them into my house to complete work, they always pay attention to the smallest details and clean up after themselves. I am thoroughly impressed that this company can find such great men and women to represent their brand. This time around, I had a ductless mini-split system installed. Eli and Bryan were able to walk me through every step that they were taking and made sure that any questions I had were thoroughly answered. They care -- they took time to make sure that the exterior lines were routed in a manner that was visually appealing and functional. 10/10 service and I would (and will) call them again for ANY home improvement that they cover."

Practice makes perfect, and Varsity has been at it for over half a century! What began with a Navy veteran’s simple dream — to teach the value of honest, hands-on work to his children — has grown into one of Long Island’s most trusted resource for plumbing, heating and air conditioning services. Varsity’s mission has always been clear: to serve our neighbors with integrity, solve home service challenges with innovative solutions, and provide lasting results. Our dedicated crew is background-checked, rigorously trained in the latest technology, and excited to exceed your expectations. Above all Varsity is here to EARN your trust—not just for today, but for years to come. Let’s tackle your home service needs with the quality and care you deserve!

"We had an emergency after a power surge that fried our furnace. Varsity was at our home first thing in the morning. Ralph went through a thorough diagnostic process with us, went over all of our options with prices, and we ultimately replaced our entire unit. The work was done efficiently within hours. No mess to clean up afterwards, and the techs at Varsity returned our home to the safe, warm environment we needed in preparation for a large winter storm. The techs took proper precautions when entering our home, even going so far as to wearing shoe coverings to protect our floors. The service manager communicated the entire process with us before it was happening, keeping us informed every step of the way. The employees at Varsity treated our family like their family. They made our urgency their priority. Every employee we spoke with was kind, respectful, and thoroughly educated on the situation, even the customer service representatives."

"Masters in AC Installation! I recently had a 4-zone multi-split unit installed in my home in Brooklyn and I couldn't be happier with the entire experience. From start to finish, Weather Masters NYC was a pleasure to work with. I consulted with 4 contractors, and Weather Masters offered the most reasonable pricing. Mr. Sam took the time to clearly explain the system and answer all my questions, which I really appreciated as I?m new to split unit systems. The installation team was punctual, professional, and incredibly respectful of my space. They kept me informed throughout the process and provided thoughtful guidance on the safest and most efficient setup, given the limited space available. Their work was not only technically sound but also neat, clean, and aesthetically pleasing. I felt completely at ease working with Weather Masters NYC, and they?ll definitely be my go-to for any future HVAC needs. I highly recommend them to anyone looking for reliable, high-quality AC installatio"
