"The original job was performed to my satisfaction, and I rushed to Judgement to give a favorable review! After that I had an issue a few weeks later and just kept ignoring my calls and texts. I tried 10 days ago to reach out about a Non-Emergency pin hole leak and Craig asked when I am available and I gave him a 7 day schedule because I had 2 doctors appointments last week but I am a retired senior so my schedule is 90% free and STILL NO ANSWER! I then reached out to his associate Alex who ALSO IGNORED MY TEXTS! NEVER DO BUSINESS WITH THIS CLOWN ORGANIZATION AND CRAIG IS A TOTAL FLAKE WHO ALL OVER THE PLACE AND 1,000% UNRELIABLE!!!!!!!!!!!!

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."
