“Heather is so knowledgeable and easy to work with!”

“I reached out for help with my AC unit that wasn’t cooling, and they came out the same day to diagnose the problem. Mark, the technician, was very knowledgeable and took the time to explain the issue clearly. I highly recommend their services to anyone.”

- Carlos Caraballo

“Would give even more than 5 stars. When the boiler kicked it in November we got a couple quotes and then were referred to A&S. They were out on a Sunday to see the system and what needed to be done. Because there was no heat in the house they prioritized the job and even arranged 0% financing for the whole thing without holding up the project. We were up and running in just a few days and just take a look at the quality of the work. The basement's never been so clean....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!!!”

- Martin Goldschmidt

“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 has been great in the past servicing my Boiler, but this was the first time for my AC split system. Scott the service technician had and impressive knowledge of my AC unit. He had a great attitude and he explained while working the problem needing repair. He checked and verified the repaired unit recommending I schedule a future system cleaning next spring to improve the system air quality and prevent another breakdown. Scott exceeded all expectations.”
