“I have been using A&S for over ten years plus for regular annual service as well as new installs. They have installed new A/c units , new HW heater and new gas furnace over the years. Today, I had a new H/w heater installed at my new home as the old one quit on me and the response was excellent. had a new unit up and running within 24 hrs of my initial call to them Prices were very reasonable, and installation was without any issues. Highly recommend.”
Customer Reviews
“I had my first experience with A&S Nathan HVAC on April 29, 2025. Making the appointment was a breeze. Received cordial service over the phone.
On the day of the service (tune-up and cleaning of 2 C/A units and also oil furnace) the technician Dave M. arrived on time and was very pleasant. He was neat and efficient. I call the office and ask that they give him a raise as they needed to retain him as an employee!!
I am VERY happy with the service that I received and will use this company every year going forward for all my HVAC needs.

“In this day and age, it can be challenging to find a company that is responsive, reliable, competitive in pricing, and does OUTSTANDING work. A&S Nathan LLC is simply the best in the business. Jake (the handsome business owner) and his staff added an additional heating/cooling zone to my newly built colonial without a bump in the road. When I first notified A&S of my need, Jake quickly came out to assess the project and formulated a plan of attack. Not long after, the A&S team arrived on the job and took care of business in only a few hours! BOOM! 5 out 5 all day long. The founder of the company, Allen has established themselves as the ELITE in the HVAC world. It should also be noted they legitimately look out for your best interest.”
“We called A&S Nathan Heating & Cooling LLC after-hours and they contacted us back within minutes to help us with our issue
Their staff is very professional, friendly, and helpful.
We recommend them highly.”
“Of course A/C always breaks on the hottest most humid day of the summer. I have not previously been a customer and called based on the recommendation of a friend. I left a request on the website at 7:00PM. Got a response within an hour promising a tech first thing in the morning. Sure enough, John showed up at 8:00AM sharp. Clearly a very knowledgeable professional. Diagnosed the problem and replaced bad parts (he had the replacements on the truck) and was gone at 9:30.
It doesn’t get any better than that!”
“Technicians were great. Really focused on preventative maintenance. Tested airflow temperature differential, belts, checked water chases to ensure no clogs were forming. Great job. 40 minutes for 2 unit service.
I will definately use Nathan for my annual service. -LZ fairfield CT”
“I just wanted to say is on Friday October 31, 2025 we needed service done on our oil burner. Your technician Mr Craig & I forgot the other gentleman name. They did an awesome job doing a tuneup on our oil burner. Our neighbor recommended A&S Nathan. Your company did an awesome job on Friday thank you so much.”
“We finally decided to switch to natural gas in our house and we were looking for a heating and cooling contractor to do it all! Gas in the house, furnace, central air and an on-demand water heater. I knew this would be a big job. As soon as I began looking, I immediately saw many recommendations to use A&S Nathan Heating & Cooling LLC. I did get a few other prices for the job, but once Jake from A&S came by, I immediately felt he understood exactly the system that we needed. With their competitive price, I was hoping that the install would go smoothly and the system would be installed in a timely matter. I HAD NO REASON TO WORRY! The A&S Team showed up right when scheduled and went to work. They actually worked on a few different areas at the same time. Their work was always neat, the yard and house were always clean. Heather and the rest of the incredible office staff is on top of everything and they make you feel like a valued client. With this recent heatwave, we've really had an opportunity to try out our new central air! It's unbelievable. I would highly recommend Jake and the team at A&S for all your heating and cooling work. They are professional, kind, and Incredibly experienced! JOB WELL DONE!”
“Quick response and spot on with repairs and all very resonable!!!”
“I've been using A&S Nathan since i moved into my home 11 years ago for all heating and Air Conditioning Services. From the office staff to the technicians they are a A+ business!!!”
