“I had annual service done on my HVAC systems today. The guys did a great job! They arrived on time and were very friendly and professional. They explained everything to me and gave me my options to keep everything working as efficiently as possible!”

“A&S Nathan is a great company, and I highly recommend them for any and all heating and cooling needs. From the office staff to the installation crew, everyone was respectful, professional and helpful. We had a big job to convert to propane and remove our old water heater and oil tank, and everything went smoothly. Thank you to Ian, Toni and everyone at A&S!”

“After having an issue with our thermostats and heat, we needed to get HVAC out to help. A&S had the best reviews, and I had seen them highly recommended on Shelton's local facebook group. On top of that, our electrician said they are his go-to company! Ian and Colton came out today during the estimated appointment time (they send you a text when your tech is on their way), and they immediately got to work. I was impressed with how quickly they worked-- not rushed, but with intention. They were able to solve the problem in no time, educated us on what was going on, labeled our wires and helped organize them a bit better, and also had thermostats on hand they were able to install. We were very impressed with their professionalism and knowledge. Will absolutely be using them as our HVAC company moving forward!”

“A&S Nathan is quick to respond, work within reasonable budgets, and turned around a furnace replacement IN A DAY (in a very cold January week!). Throw on top, they're very nice people top to bottom, there's no other choice for me in the area. Will continue to do business with them, and always recommend A&S Nathan for years to come.”

“I am completely satisfied with the way your company conducts its business. I am in the building industry as well and I know how important customer service is as well as the quality of your work and products. Your response time from the onset as well as the turn around time for the install was excellent! I felt so fortunate that you made my situation a priority. Your techs/installers were totally professional and considerate as well as efficient and your office staff couldn't have been more helpful in the scheduling and the financing assistance they provided. All in all...I will most certainly recommend your services to whomever is in need of any repairs or installs. Thank you again for an amazing experience under a stressful circumstance.”

“Craig came to service our furnace and he was excellent. He identified an issue we were not aware of, explained it thoroughly and took care of it. We recently moved into our home and the initial service was done by another company. We will stick with Craig going forward. A routine annual service turned out to be a bit more involved and he handled it professionally and efficiently. I recommend A&S Nathan based on today’s experience, and Craig specifically!”

“Excellent experience from start to finish. Jake and his team of HVAC technicians are experts at their craft. The installation of our new heating system is a work of art. The guys left the area spotless and to top it off, the cost was extremely competitive. Highly recommend A&S Nathan. If you live in the area, it's no mystery why you see their trucks everywhere. P.S. The office staff is very helpful and friendly too!”
