“Great service. Very knowledgeable technicians.”

“To anyone that this may concern: I seldomly take the time to write a testimonial. However this company deserves my accolades for their exceptional service. Within the past two weeks I signed on for their 24/7 oil furnace coverage for four individual properties. I have three single family homes in Oxford, Connecticut as well as my own personal residence in Woodbridge. After servicing my rental homes, I made the fourth appointment to service my own personal home in Woodbridge. On the fourth service call, I proudly shared with my Technician (Craig) that my hot water boiler (Weil Mclain) had never given me any issues after fifteen years of faithful performance. Of course the week of my last servicing, the boiler developed major leaking. Thanks to A&S Nathan's receptionist/coordinator (Beth) the entire project was orchestrated through her manager (Heather). My hot water boiler was installed quickly with flawless installation. Installation technicians, Scott and Craig, are truly like having "family member in the business". This company is so thorough and conscientious, Heather was able to have Weil Mclain stand behind their hot water tank after fifteen (15) years of service at no cost to me ! It is without reservation that I recommend A&S Nathan Heating & Cooling LLC as one of the most reputable and trustworthy firms which I have had the pleasure of doing business after fifty years of residing in the Valley. If you seek the best service for your dollar, in addition to people you can trust with your comfort, look no more - A&S Nathan Heating and Cooling delivers on all counts. It is without reservation that I recommend this business without any hesitation what-so-ever. Thank you, yet another grateful customer, Bob Caetano Woodbridge”

“I am a first time customer with A&S and they came highly recommended. My serviceman showed up within the time I was told and actually apologized for not being able to be to my house sooner. He cleaned my furnace in a timely manner and explained a few things I should probably think about repairing next time. He was very thorough and explained everything. I am very satisfied with the work done and the serviceman! I would definitely recommend A&S!”

“Big shout out to A&S! Our fujitsu mini split was blowing warm air, called several shops and got the run around or no call backs. A&S was able to send a tech out the next day, THAT SHOWED UP and on time. Scott went right to work found the issue and fixed. Told us what the issue was and explained if certain things happened what kind of costs we'd see if they happened. Will definitely be calling them back when we want to expand this system to more rooms.”

“I've been using them for years and recently brought my parents on board. The office staff is courteous and professional. Never an attitude for any reason. They show up in the time frame they committed to. Techs are friendly and knowledgeable and honest. Would 100% recommend.”
