All of my interactions from the office to the technicians have been great! The price was reasonable too so all around a good, honest company.”

“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.”

“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.”

“Techs came out to diagnose my oil furnace,Dave M and David S were very patient and explained everything, and corrected all the things that were left from the previous owner, then someone came back to finish up service to make sure everything was working correctly since the oil gauge wasn't working correctly. Highly recommended.”

“Look no further - if you're trying to find the company to use, this is it. Could not have been a better experience. I reached out for help with my furnace situation and setting an appointment was easy and pleasant. CC was added on file which also meant I didn't have to worry about it later for payment, text was sent 20 min before arrival, and arrival window was accurate. Mark came out to fix an issue with my furnace and was fantastic. Everything was quick and easy and they got my thermostat controller issue working enough for my needs while they wait on a part that needs replacement. I also had a ton of questions since my house is old and has some unique issues, and he not only answered everything but gave other suggestions and recommendations. Mark also walked me through the follow up process for when they receive the part and can come out again. Obviously needing help is not always the best because you're dealing with a crappy situation, but they not only turned this into a positive experience but were quick to get us back up and running. Thanks again!!”

“A & S Nathan has repaired and maintained my furnace for several years now and I'm VERY happy with their service, honesty and reliability. They are easy to communicate with and everyone has been so helpful. I had used several other companies prior, and working with A & S Nathan is by far the best experience I've had.”
