“We purchased and had a new Water Heater installed. I can't say enough great things about he company. They were on-time, did the job well, and at a better cost than others. I would hire them again in a heart-beat!”

“My furnace kept going in and out on a cold day . Even though they couldn't fix my old furnace (30+ years old) on the initial service call , the tech was very thorough in diagnosing . Concerned about having no heat at first but they came out first thing next day to install a new furnace . Nice and professional installers did a clean job and even pointed out a few other suggestions . Price was very reasonable for a furnace install”

“I very rarely write a review for a company but this is my SECOND review for A&S NATHAN… From the office people to the techs themselves, there is always a feeling of family and professionalism when you need them…I want to particularly send thanks to Mark who is very meticulous and conscientious…. Mark is my assigned and requested tech and has always fixed or corrected our issues on the 1st trip and as economical as possible… He is a definite asset to the company and to us as well… BLESS HIM!! Yesterday I needed them for a thermostat replacement and I thought I had the correct location, Mark arrived promptly and advised me that the opposite wall would be a better location and explained why… This is what I am trying to express, they just don’t do the job, they do the job correctly with courtesy and without cutting corners!! I have used A&S for my A/C, Furnace & boiler, and Oil tank replacements as well as all service and am completely satisfied… Jake, Heather, Toni, Joanne, Mark and the rest have always been fast to respond and fair in what the company charges.. And quite honestly, you get what you pay for!!! There are a lot of HVAC contractors out there, A&S is the best!!!”

“I live in Florida and I needed to have my old heating system replaced in Stratford, Ct. I needed a company that I could trust to do the job. A&S Nathan Heating provided that. They were easy to work with and did a wonderful job. I recommend them highly.”

- Philip Michitsch

“We’ve been customers of A&S Nathan for some time so the decision to use them was easy when it came to replace our boiler. The process was easy and the installation was quick and seemless. The staff was professional from start to finish. Thank you!”

“7pm on a Saturday night & my furnace goes out. Who did I call? A&S Nathan of course. The tech was there promptly. Clean & professional. I had heat in less than an hour. These guys rock. I will need a new furnace & hot water heater soon and I can't think of anyone else to do it. Thanks again to Al and your professional staff.”
