Meet The Owner
Moshe Shem-Tov
The youngest of 8 children, Moshe had to learn early on how to keep his COOL even when the HEAT was on. Is it any wonder that he has been a HVAC maven for the past 24 years, bringing comfort & relief to families & businesses, large & small? Passionate about soccer, dancing & most of all, his family, Moshe’s goal is to provide the best HVAC performance to his customers, with a focus on energy efficiency. He is best known for his masterful diagnostics as well as his personable & highly responsive service.


Great, quick, effective service as well as a good person to work with when deciding on the new system for my house. I share AMS with everyone I know. They're cool people! 😉


Moshe is so easy to work with, came in at a MUCH lower price, and work was done quickly, and his team did a great job cleaning up after they were done.


Great service. Came quickly and got my AC working in no time. Pricing very reasonable as well.


AMS has saved us on multiple occasions. He is responsive, knows exactly what he is doing and each time has fixed our AC quickly and affordably. Call AMS. Simply the best.


Moshe has installed new systems and serviced systems for me. He is very professional and to the point. I would not use anyone else for HVAC work.


My system stopped working on one of those cold days. I called AMS and they came right away. Fixed the problem and the charge was very reasonable.


Quick response, quality work, reasonable prices. Just replaced our entire dated HVAC and did it on time and on budget.


AMS did a great job with my AC install last summer. Good communication, fair price, no nonsense, accommodating of my schedule, and quality work. Highly recommended.


Moshe has been my HVAC go-to person for 20 years for this old house. He is very skilled, knowledgeable, and reliable. Would never call anyone else.
