Our ac broke over the weekend. We reached out to Ams through Yelp but a bunch of other contractors messaged us. Since we were desperate, we let one of them come and look at the system. He told us we would need a new compressor which was on back order and we should probably replace the whole system. This would cost from $4000-$12000. The ac unit had been replaced in 2018 and I thought that seemed aggressive. Then Moshe messaged me back. I wanted a second opinion before I was going to spend thousands on a whole new unit. Moshe came on a Sunday morning and he diagnosed it needing a new capacitor (not a compressor) and he fixed it that day for $800. I was elated. I signed a service contract with him. I've seen this show before with HVAC repairmen. Inexperienced and/or dishonest contractors recommend spending thousands on a whole new unit because they don't know what they are doing or are trying to rip you off. Moshe is the real deal!! Experienced and honest. Don't waste your time and money with anyone else.

What a great experience. Moshe came over within an hour of my call he was only about a mile away and could fit me in on his way home on a Friday. I told him I had just changed the start capacitor. So we checked the wiring schematic and found the problem rather quickly. A dear friend of mine recommended Moshe to me years ago. So glad I reached out. Super honest and dependable.

We have two A/C systems in our house, and both broke down almost same time. We called AMS Air conditioning and Heating. It is a great company and Walter is great. He did amazing job. He is very knowledgeable. He diagnosed the problems accurately and fixed both the A/Cs very efficiently. Also, very nice of them to do the diagnosis of both the A/Cs at the price of one and gave us a new customer discount. Very fair pricing. I would definitely recommend AMS to everybody.

We have been using them for years, and are MUCH better than our old service. They dont try to sell you a new unit unless you absolutely need it, instead he will figure out the problem and fix it if it can be fixed. Their prices are fair, and they do good work. We were able to get 20+ years out of our water heater until it finally needed replaced. I referred them to my neighbor and she has been using them for years now as well. I highly recommend!

Moshe and his team are real pros. They came on time and did outstanding work for a reasonable price. Moshe is very knowledgeable and responsive. Overall I am very pleased with AMS and would highly recommend their services to anyone with HVAC needs.
Follow-up: both times Ive had any questions he shows up the same day to troubleshoot and solve the issue. Im still very impressed and pleased with the level of service.

I had a fantastic experience. The AMS crew were extremely efficient, gave me lower cost options that others did not mention, diagnosed and repaired in a matter of hours what some other people were telling me would take at least couple of days. Would wholeheartedly recommend for no-nonsense efficient and reasonably priced HVAC repair. Will definitely be calling them when my nearly 20-year old system needs replacing!

AMS saved US this past December. Without any warning our heating system went totally out of commission. After contacting AMS, they quickly scheduled a technician to come to our home the next day. The technician was very professional and polite, He diagnosed the problem and the next day provided quotes. I did my market research and his price was competitive and fair.
AMS was able to procure the equipment needed within a day and we had a newly installed system a day later! I am so thankful.
Beware of OTHER companies that lack decent customer service and inflate pricing. AMS provided the system we needed and we are more than pleased.

Moshe responded within minutes to my enquiry (gas furnace not heating), researched the problem (after I gave him the error code) and called me back with the manufacturers recommended solution- which I was able to implement - and this solved the issue. All done over the phone at no cost. He even researched and quoted me in minutes the cost for a new control board (in case it was needed), Went out his way to be so helpful - very polite and helpful guy, highly recommended.

This family owned business is by far the most responsive and timely I have had the pleasure of working with.
I am MD homeowner, and a novice for home repairs. I have relied on their quick service as a primary occupant and landowner for over 7yrs. Two separate AC units installed during that time, both operating VERY well. Any simple question I have is answered within 24hrs. Thank you very much AMS.

I had a problem with my HVAC, I called a company that told me that it need to be replaced.
I decided to take another opinion, and how glad I am that I did it.
In less than an hour the HVAC was fixed.
They saved me a lot of money.
I totally recommend them, honest, reliable and professional.

AMS replaced my 23 yo furnace and AC the next day after I called. Sold me a Bryant Preferred system installed for $7200. Good deal, excellent installation, and fast response. That night, I messed up the thermostat, and Moshe came back after dinner and corrected the problem without charge. Just what you need when your AC dies during a DC summer!

Really really great service, quality of work, responsiveness, AND prices. Installed an AC unit when the old one died at peak of summer at best price and really fast. They were able to get a brand name unit even during peak COVID supply issue times where everyone else was giving me weeks time-frames to fix.
We had a power surge which knocked out a unit, I called on Sunday and they diagnosed and fixed the issue Monday morning. Didn't even expect such fast turnaround. Would give 10 stars!

Easiest five star rating ever. Could not be more thankful for Moshe and the AMS Air team. We recently bought a new A/C and heat furnace and we could not be more satisfied. Customer service and communication was outstanding, the pricing was very competitive, and the delivery and install happened without delay. A+++ all the way around. We are AMS Air customers for life.

Had a new HVAC system installed with AMS last month. Moshe was prompt, professional, and to the point - no pressure, no upselling, no fluff. After extensive research, his quote still came below those with comparable experience and reviews. His team was also prompt and respectful. After the installation, I mentioned my concern about a particular fitting; it was actually my misunderstanding, but they came first thing the following morning and replaced it, no questions asked. The house has been consistently cool despite the heat waves. Will certainly work with AMS in the future.

I have been a customer of AMS for air conditioning and heating services for almost 15 years for the reasons that they are professional, responsive, honest, reliable, prompt and deliver high quality service at reasonable prices. They have helped me with replacement of an air conditioner unit and a furnace and I rely on them for the servicing of both systems. In addition they have helped me in emergencies during heat-waves in summer and freezing weather in winter. Mr. Moshe Shem-Tov, the owner has been a highly respected specialist in the air conditioning and heating business for decades and the high marks are well-deserved.

Its hard to find a contracting company that is going to be responsive, honest, and reasonable, but I finally found one. I service my AC regularly and have had a couple issues. Prior to finding AMS, I used 2 other AC service providers who did not take the time to identify issues and had me waiting for hours for their arrival. AMS' Moshe is punctual, professional, and thorough in finding out what the issues are, if any. I will continue to use AMS and highly recommend them to anyone who needs AC service.

I used AMS services at least 4 times. AMS employees are both knowledgable and competitive. They constantly responded to my calls regardless of the time. They work quickly and efficiently and always leave my home clean after they are complete with the job. I highly recommend AMS Home Improvement to anyone looking for a contractor.

We worked with AMS Air-conditioning for over 20 years and received a very professional and successful service every time.
Today AMS technician replaced the condensation pump after identifying that this was the core reason for a whole bunch of problems we were experiencing. He showed up on time, did the service and thoroughly explained to me what the problem was and how it effected other parts of the heating system.
We recommend AMS to all everybody who asks us for reference info.

I have been a customer of AMS for quite a number of years. They are my go-to HVAC contractor. I have replaced four complete systems with AMS in four separate houses. Two were renovations, one was a rental property and one my personal residence. Each time the service was prompt and reasonably priced. When a problem came up that caused the system to stop working they came quickly and diagnosed the problem correctly while minimizing my down time.

Last summer, on a miserably hot day, my AC went out; and this winter, on a miserably cold day, I lost my heat. For both events AMS responded quickly and fixed the problem at a reasonable cost. I admit, I don't have much experience with other heating/AC places; but with the excellent service I got from AMS, I have no need to look for anyone else!

It is not easy to come by today in what is AMS providing while other companies (that I will not mention their names) are charging you extra fees for nothing or using the fact that you might be no so educated and selling you services or parts that you really dont need.
At AMS you really cant find this type of service!!!
But you can find the following:
Skills, Honesty, reliability, best customer service, lots of options to choose from.
Moshe will be your best choose for Air Conditioning because there is no other that provide services like that, he is the best that can be found in this area.
Sincerely,
Avraham

We've been using AMS for almost 15 years. They are very reliable and either show up as per the arranged schedule (90% of the time) or call to reschedule. They've provided various services for our cooling/heating systems. They've fixed a leak in the cooling system; a furnace that wouldn't ignite on its own (an emergency repair on a snowy weekend with a short notice); a humidifier that stopped working, and most recently, brought back to life a heat pump that died due to a short circuit - that's a tough one to fix, given the gazillion of wires in the system. After adding space to the house, they replaced the units with a higher capacity system. If we can't get a live person on the phone, we get a call back within a reasonable time frame. We'd use them again, if needed - so should you!

AMS installed a high efficiency HVAC system in our house about 20 years ago. With prompt services and adequate maintenance the system still works just like a brand new one.
Service calls are returned immediately, service is excellent, and utility bills are very low.
I recommend him and his company as your reliable HVAC company, because you will never have any worry about your heating or air conditioning

AMS is an air conditioning and heating business with a soul. Unlike the huge, faceless and often voiceless HVAC companies who are often hard to reach and take a long time to address your problems, AMS provided us immediate assistance when our igniter went out, bringing much needed warmth to us and our 3 young children. On other occasions, AMS has provided us with phone diagnostics at no charge and helped us address the problem at no cost. If you want a responsible, personable solution to any HVAC needs, AMS should be your first stop.
