“Had Mark at my house for service. Up and running better than ever.”

“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.”

“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.”

“We have been using A&S Nathan for several years for yearly furnace cleaning and this was our first need of emergency furnace service. On 9/23, I called A&S Nathan at 913am as our furnace was leaking water. The phone staff were so reassuring to this frantic caller and promised to send a technician ASAP, between 10a-2p. Mark, the technician, arrived at 1022 am. He quickly and throughly assessed the situation, stopped the leaking water and determined what would need repaired. Mark was professional, knowledgeable and patient with my multitude of questions. He made sure we had hot water until they return next week to complete the repair. Thank you, Mark! With much appreciation to the entire A&S Nathan Family, Kathy S”

“I set up an appointment with Debbie, who was very kind and had two excellent techs out to the house. They repaired and performed maintenance work on my A/C in a professional and timely manner. I was completely satisfied with the service and the value I got for my money. I trust A&S with my home repairs and would recommend them to do the same for you.”
