“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.”

“"Wow wow wow! What a fantastic company. A&S Nathan saved us from baking last week during the biggest weather challenge of the Summer so far! They arrived earlier then the time frame quoted and then they expertly installed a high efficiency A/C system that replaced our original 35 year old unit, which required considerable redesign to connect the new system to the existing duct work. Their workmanship was excellent. Thanks to Jake, Heather, Mark, Paul, and everyone else for a job well done. We all will sleep cool this Summer and many Summers to come!" PS: The dog's are happier than we are!!!”

“The crew did an excellent job during my conversion from oil to propane. The work was of the highest quality and they completed it in a timely and organized manner. Their attention to detail was impressive, and I was particularly pleased with the way the front office managed the project from beginning to end. The crew was a pleasure to work with, and they were always courteous, communicative, and professional. I would not hesitate to recommend them to anyone considering a similar project. Thank you again for your excellent work.”

“The AC stopped working on the hottest day of the year at my business. I figured I would never find anyone to come out same day. I spoke with Allen and had them come out within 2 hours of my call. They quickly figured out what the problem was and even took the time to show me why it was causing the problem. They had it fixed quickly and then showed me how to tell which zones are doing what. I'm so grateful to have found them and really appreciate how quickly they came out.”
