“Called A&S for no heat on Christmas Eve, they had someone at my front door in 25 minutes. The technician was knowledgeable and efficient and had my heat back up and running within an hour. If you're looking for the best HVAC company in the area, look no further.”

“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.”

“10/10. Amazing Crew from top to bottom got my A/C back up in running same day during the first heat wave of summer.”

- Tommy Lenahan

“I’ve used A&S for many years. Fast, professional and reasonable! Available for emergencies (think New Year’s Eve!). I frequently recommend them to friends, family and neighbors! You can’t go wrong with Al and his team!!”

“Contacted Jake at A&S on a Wednesday that I needed my hot water heater to be cleaned and they told me with the holidays they were 4-6 weeks out. Jake asked if there was a reason he thought I needed it cleaned and I mentioned that my water was coming out brown. Jake dropped everything to order me a new unit and burner and had his crew here on that Friday AM to install it. Knowing this was a last minute ask, I figured the price was the price and potentially even more knowing they would have to move a schedule around - WRONG. The A&S team gave me the best price around with the highest quality work to go along with it. His team completed the job in a few hours and I didn't even know they were here until they pinged me to show me my new unit. I would never use another company for any Heating & Cooling needs.”

“I have been using A and S Nathan heating for a couple years now . Very professional, helpful and on time . Mark came out to my moms at 8:00 on Friday night . Dispatch told me where he was and what time he will be there . Mark showed up early , was very helpful in explaining to my mom what happened . He fixed both problems in a short time . Thank you guys for showing up and fixing everything so fast and helping my mom out on a Friday night !!! Definitely suggest calling if you have any heating problems !”

“Definitely the best HVAC company in the valley. Family owned, the employees are knowledgeable, professional, and had the utmost respect for our home, leaving their area cleaner than when they arrived. I'd refer any friend or family member to them.”

- Thomas McCormick

“I used A&S Nathan to repair my a/c unit. They were there in what felt like a couple of minutes. Mark D was the guy that came out, he repaired my a/c without any problems. He was definitely a stand up technician who knows his stuff , he didn’t mind at all that I was watching and asking questions. Next time I have any boiler or a/c problem I’m calling these guys and requesting Mark”

“Just had a new oil furnace installed in my old house. This company was easy to work with, gave me a fair price, but the install was top notch. The technicians were respectful, answered all my questions, and went over everything I would need to know to keep this unit running perfect. When they were done everything was actually cleaner than when they got there. On the initial fire up of the unit, it was super quiet and warmed up the house much quicker than my 30 year old unit. I highly recommend this company. Since it's not that cold yet, I'll do a follow up as to the brand of furnace and how it goes through the winter.”

“A&S has been doing my heating and AC for many years now. Awesome and quick service, very professional, everyone knows their stuff! Al & Jake are very knowledgeable with all they do. We highly recommend them!!!”
