After calling around with no luck, we reached out to Dyno Heating and Cooling, and they were incredible from start to finish. Kristy, the receptionist, was so helpful and reassuring when we called in our panic. She quickly arranged for Mike to come out to help us and made the whole process stress-free. Mike arrived at our house within 45 minutes of our late-night call (at 10:30 pm!). Despite not having worked with us before, he treated us like loyal customers. He quickly diagnosed the problem, replaced the broken part, and even stayed an extra 20 minutes to make sure everything was running perfectly before leaving. The service was professional, fast, and extremely reasonably priced--especially for an emergency call so late at night. Both Kristy and Mike went above and beyond to take care of us. We highly recommend Dyno Heating and Cooling and will absolutely be calling them again for any future heating or cooling needs. Thank you for turning a stressful situation into a great experience!

When I saw a negative Yelp comment (about clean up), I couldn't have imagined how easy it would be…read moreto call the contractor to address anything minor like that. The comment made me a bit nervous to settle a contract -- and I told Dave to please pay attention to the wiring in the attic (which was my concern). After the AMAZING experience my family had with KinTech, I wanted to leave my first-ever comment on Yelp for Dave and his company. I am not an easy customer :). KinTech is a local Long Island company and its service (both its job and customer service) felt local/neighborly. When Dave (the somewhat hard-to-believe soft-voiced manager I had talked to on the phone) stopped by for the estimate visit, my wife and I were taken aback positively for his relaxed, friendly dealing (he had a new kind of tea with us :), while sharing details and options). In response to our situation of having already dumped too much money on prior upgrades, he found an affordable configuration for our transition from baseboard heating only to central heating/cooling, including the latest tech and conveniences. But our 5 stars are not just for the quality of mateiral and work and the professionalism of the people who came in our house (Dave sent the most friendly pair of men we've had working in the house). Dave is different. Dave communicated in the most professional and friendly way among maybe 20 contractors we've worked with in the past decade on Long Island as home owners (he reminded us of the genteel South, without the occasional lack of experience with diverse customers LOL). We didn't sense any dishonesty (very common in most home repair/service businesses esp. up here in New York) and that made us very comfortable with Dave. He did ask for a few extra days when he had to juggle different projects, including his gramdma's house that needed urgent attention. But he didn't play games with us, didn't treat us like however the "market demand tells" (as one contractor blurted out recently), and he LISTENED. This guy is something. Give him a chance, and if the project at our home was an exception, share a different perspective. The project was finished on time, pitch perfect, and Dave said he's even willing to come back and calibrate the air flow and add an extra vent. We were already surprised when he sent his guys to double check and clean up. So, I guess customers should communicate our demands and give hard working people a chance to rectify small things after they do all the major and difficult work right (it's a different matter if someone messes up major things or uses a generally problematic approach). As a Long Islander, it makes me proud to see people like this reflect our culture -- not the weirdos especially of the older generation who take customers for granted (I've come across a bit too many of those, including among the younger business owners). I would love to see KinTech grow and to maintain the very, very, very friendly professionalism that Dave has established. KinTech and Dave and the two friendly guys all get 5 stars and a big invisible smiley for the phenomenal job in December 2021.
