"We had an ac unit put in two years ago. It never worked quite right. He came to check situation a couple times last summer - being it was a new unit - said to leave on auto/70 and should be fine. Still would not work correctly, hot days wouldn't work at all. This year was not working at all, only HOT air would come out. Once again came this summer, added more freon, stating there must be a leak somewhere. They couldn't find leak, told us we need to replace all the copper piping to fix the not even found leak. Wanted to charge insane amount money to fix a recent unit they installed that never worked in the first place! I tried calling the business a few times with not a single call back to speak with me. Thankfully i was forced to get it checked by someone else - it was an EASY fix! The flares were never tightened and there was a welded area that we were never told was done in first place. Do not trust this place; horrible customer service, unreliable, and afraid i was almost scammed!"

"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."
