Client Testimonials

During the winter of 2000, we decided to add a humidifier to the furnace. One of my coworkers recommended AMS and Moshe was the one who did the installation. I guess he has left a very positive impression on me. Fast forward 20 years later, our furnace blower started to make squeaky noise and few days later, it stopped completely. So I called Moshe in the evening and got an appointment at noon the next day.

Since both the furnace and air conditioner were old, it was really no sense to put more money on them. We ended up getting a furnace/air conditioner combo at a very reasonable price. On the next day, Moshe and Walter, the technician arrived punctually and installed the system in about 7 hours, leaving the job site neat and clean. Moshe is prompt, courteous and knowledgeable. I highly recommend him for HVAC needs.

We purchased entire electric heating and cooling unit (condenser and inside airflow coil unit) from AMS. We had renovated our basement prior to our system went down. It turns out our wire got damaged, which was discovered by AMS during the installation. They fixed it free of charge. They were professional and charged a reasonable price. I appreciate the professionalism, which is extremely difficult to find in this industry. I got 6 other quotes before choosing AMS. Some of them were downright crooks. I’m glad that I made the choice. I plan to use them for my maintenance.

I am not one to write reviews but AMS deserves to recognized. They are responsive, dependable and just good at they do. I called on a Friday morning around 7 am and they got back to me promptly. They were at the house around 9 am and fixed the problem after thoroughly checking the system. AMS is our go to!

Moshe arrived as scheduled for all appointments. Job was completed on time and no surprises from the quote. Team and owner were professional and worked effectively. We had a full ac & Furnace installation, and would be happy to recommend AMS for any residential AC service.

I rarely give feedback. But, I have to share how much integrity and excellent service Moshe and his team provides. I have used them three times for different issues and they always exceed my expectations with prompt and thorough service and treat me with complete fairness. They are simply excellent.

Great choice! Called on a weekend when our outdoor compressor died and AMS was there right away. Within minutes, the problem was fixed (and compressor was cleaned) for a very reasonable price. Extremely happy I called AMS!
