“I've been using A&S Nathan since i moved into my home 11 years ago for all heating and Air Conditioning Services. From the office staff to the technicians they are a A+ business!!!”

- Customer Service

“I have used A&S for several years now, mostly for general system maintenance but also for replacement of a tankless water heater. They are always on-time, professional, and do great work. It's difficult to find a quality business with quality emoloyees, but this is certainly one of them.”

“The A&S team is always helpful and professional. They recently took time out of their already very busy schedule to replace my furnace so my family could have a warm house again. The work was swift and neat. We are very happy.”

“Jake provided us with a detailed estimate with options and talked us through it so we could understand how best to match our needs. Ian and his team did a great job installing, showed up on time, kept us informed on progress throughout the day, and finished when they said they would, including a walk-through. Additionally, they did a great job cleaning up. Heather was behind the scenes at the office, answering our many questions efficiently. Overall, a team of professionals!”

- Sarah Duff

“Scott came out right away to check that our system was working efficiently and also upgraded our Prehistoric thermostats. Scott, along with everyone in the office, was friendly and professional. A&S for the win in this heatwave!”

“I used them to do a oil furnice tune up. I absolutely love it 100 percent I will call them this year as well. The guy that came have a really good knowledge of what he had to do. He did everything quick and clean didn't leave no mess at all. Check my furnice and adjust my burner cause I was burning to much. After that he made sure the furnist was burning right. It has been almost a year and no more soot in mu basement at all. And all the filter new as well.”

“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!”
