As a homeowner who has dealt with every home repair and replacement there is I can honestly say that my experience with ADI Heating and Air Conditioning was the best customer experience I have ever had. The ADI team spent a great deal of time analyzing and measuring our existing system as well as designing the new system. I vetted 3 quotes and ADI pricing was the most competitive. As all homeowners know It was obvious throughout the end-to-end process that Mr. Chazoom and the ADI team take great pride in installing “the right” solution. ADI was the only vendor who proactively informed us of the rebate program that we qualified for and then walked us through the paperwork. ADI took the time to inform us of all of our service plan options and answered all of our questions. I cannot recommend ADI enough. And I look forward to working with them in the year to come.

At the recommendation of several people, we had ADI Heating & Air Conditioning replace the entire HVAC system in our home in the summer of 2007. This is a two zone system and the work also required the relocation of some ductwork. We were well educated by Mr. Chazoom, the owner of ADI, on the various manufacturer’s and their systems and guided in a direction that has turned out to be an excellent choice for our needs. ADI was very competent and thorough throughout the work performed. They worked well with our general contractor; making themselves available when needed and also worked quickly in an effort to cause the least amount of inconvenience. We plan on using ADI for our annual service. It was a pleasure working with Mr. Chazoom and we would highly recommend his company.
As a recent customer of ADI Heating and Air Conditioning, I would like to point to the outstanding service I received. This was not just in the initial installation of the heating and air conditioning system, which itself was professionally carried out, but in the full follow-up, service provided. ADI in my experience assures that any equipment or system they install performs as expected and will undertake any adjustments or repairs necessary to make sure that this is the case at no extra expense to the customer until everything is working properly. They make themselves available promptly. and provide nothing but the finest service. This company has my highest recommendation as a consumer.
Mr. Chazoom and his company ADI Heating and Air, provided and installed six heat pump units, three propane furnaces, and all the ductwork for my home located in Laytonsville, Maryland. (My home is over 9,000 sq feet.) The quality of work was incredible. My architect did not provide a rough-in sketch for the ductwork, therefore Mr. Chazoom provided me with his design of the system, which I accepted. The work was completed quickly and flawlessly per his proposal.
Lonergan Homes, Inc. has utilized ADl Heating & Air Conditioning, LLC since January of 1999 for the installation of our heating and cooling systems. They have consistently performed extremely well, including meeting our construction schedules, and responding promptly to any service calls that have arisen. We are very pleased with their performance and 1 recommend them highly.

We had an opportunity to use ADI this past summer for the very first time when our air-conditioning unit failed. We could not have been more pleased. They showed up on time, their truck was fully-equipped, and they had us up and running that same day.
The Abrams Family
We first started using ADI over 13 years ago and could not be happier. From minor repairs to the installation of our new furnace last year, there is no one we’ve come to trust more!
Could not have been more impressed with ADI Heating and Air. Was looking to convert from oil to gas after many years of debate and ADI facilitated the process from start-to-finish. They treated my home with respect, offered the most competitive pricing for the work, and carefully explained the job in full detail right from the start.
The Dailey Family
We’ve had the pleasure of using ADI Heating and Air-Conditioning’s services in our home since first moving to Olney over 10 years ago. First to replace the old air-conditioning unit that came with the home, and then for annual maintenance checks ever since. We are always impressed with how thorough they are in their work, and how tidy they are in our home. We highly recommend ADI to all of our neighbors.
I am especially pleased with my newly installed HVAC system designed and installed by Mr. Ronen Chazoom and his assistant Jose of ADI Heating & AC, LLC. Mr. Chazoom engineered a customized and right-sized complete whole-house HVAC system to bring my 72-year-old Cape Cod style house in Silver Spring Maryland up to 21st century standards incorporating the highest energy efficiency and performance components for heating, cooling, humidification, dehumidification, and air filtration all at a superb value. The whole system is controlled and monitored for maximum comfort and efficiency by a high-tech slim-line comfort module thermostat, which floats on the wall. He even installed a European-style super high efficiency ductless supplemental heat pump system to solve a unique heating and cooling weakness in my second floor master bedroom, which now for the first time since I have lived in this house keeps this room wonderfully comfortable with quiet efficiency. ADI do their own sheet metal fabrication so on installation day they provided custom-built components to transition from my new (smaller) system to the existing ductwork based on pre-installation measurements (it looks so nice). Not only was I impressed by Mr. Chazoom’s craftsmanship, expert skills and attention to detail, and ability to adapt to unanticipated issues during the installation but he also exhibited a strong sense of honesty, trustworthiness, and integrity that instilled in me a confidence that this system would hold up and perform superbly for many years going forward. Just to recap: After six weeks of detailed research and obtaining multiple bids from highly regarded competitors I could not be more pleased with the performance, efficiency, and value of my new whole house HVAC system engineered and installed by ADI, and am confident it will meet my needs for at least the next two decades.
I have been using ADI for many years first for repairs and then later for a whole new system. ADI is dependable and responsive and its prices are reasonable. Their workmanship is quality and they will advise the most cost-effective approach using the best industrial equipment. I highly recommend ADI for heating and air conditioning needs.
Ronen is reliable, honest, and professional. He is always available to answer questions or come by to check on things. We have always been super happy with his service!!
Professional, dependable, and first-class sales and service!
I love the professional and courteous service of the guys at ADI!
I would recommend ADI Heating & Air Conditioning to everyone, when I lost my air conditioner due to a storm, the owner came out immediately and gave me an estimate to submit to my insurance company, the insurance company contacted him and we were able to move forward quickly. My home is now cooler than it ever was and with the system that he installed we can turn down the air while in bed with our cell phones. You know that being without air conditioning in 90 degree weather can be pretty tough, we were up and running in no time. Thanks to ADI Heating & Air Conditioning. Do yourself a favor if you need any repairs to your unit give them a call.
Excellent service and good prices. Installed a 16-seer system in my home plus upgraded the ductwork. Much more efficient than my old system.
Excellent, prompt, reliable and clean service.
I have been very satisfied with the service provided by ADI for the past 6 years. He goes above and beyond to be helpful and is very responsive!! Thanks so much!!
Great service, the technicians were on time, professionally gave us a fair price to replace the part, we got our a/c back at no time. We definitely will recommend them.
We used ADI to install two HVAC units, came on time, were fair price, honest, we will definitely recommend them.
Very experienced and reliable HVAC Co. in both residential and commercial installations. Prompt response and competitive prices. They will also get you the rebates from the local utilities to save you, even more, $$
Great customer service and workmanship. I needed a new air conditioner and furnace and got them installed in less than a week. In the middle of summer. Very nice job and extremely clean. Highly recommended.
Right in the midst of an extreme heatwave, our A/C began to fail. We called ADI heating and cooling the next morning and Ronen showed up in less than an hour. He identified the problem within 10 minutes and he had the needed part right on his truck. The A/C began to cool the house within 1/2 hour of his arrival. He was a total professional, very friendly plus his fee for the part and labor was very reasonable. We also feel like we have a trusted friend to help us with any heating or cooling problem.

Highly recommend. Honest, reliable, efficient. I have used them for the past 18 years in many different homes. Answers the call for help quickly and doesn’t try to tell you anything you don’t need. Very happy customer!!
I can not thank Adi Heating, Mr. Ronen Chazoom, enough for the support, genuineness, and professional work he and his crew provided to replace my heating and air conditioner system. He is also a Veteran Soldier!! I initially called Ronen for help with my sudden loss of air conditioning power during the most recent heating spell. He came by my home the same day, taking time out of his busy day to provide an estimate. He recommended the best option that was reasonable and economical for my house and family to replace my 26 y/o unit. He sold me what I needed, not for profit. He undercut the competitor by $2,400, who tried to sell me what I did not need! Even better, Ronen recommended – Amana – Made in the US. It works smoothly and definitely cools my house! He scheduled my installment as quickly and reasonably as possible, considering how busy he was. He even cleaned all the debris and dead rodents that collected around the old unit for so many years! You would be foolish not to call Adi Heating and Air. He will give you an honest no-nonsense estimate and I can assure you, you will be absolutely pleased with his character and professional work! Sincerely, Matt St Laurent
Very dependable and efficient service provider. I am a delighted customer of 20 years!!!
Extremely responsive and capable contractor. Has performed HVAC system maintenance and troubleshooting and is always effective. Highly recommended.
I had ADI install an HVAC unit in my home 5 years ago. It has been running great since then. I couldn’t be happier. If I ever have a question, I call Ronen and he always helps me. Highly recommend.
Installed a new HVAC for me a couple of years ago, and just signed a service agreement for this winter and the coming summer. Extremely friendly and informative about my system, and excellent price. Would recommend it to any friend that needs a new HVAC. The new system has saved me hundreds throughout the year and has provided a very comfortable environment.
Ronan and his crew were fantastic. Prompt, professional, and polite, everything was left in great condition and we love our new unit.
ADI has been our trusted HVAC service provider for 3 years. They provide excellent customer service, pricing, and recommendations on how to properly to maintain the system. Highly recommend.
Honest and knowledgeable. I highly recommend this company…..
We have used ADI (Owner: Ronen) for various repairs to our HVAC system in the past. He has always been prompt, reliable, thorough, and honest. Recently, we chose him to put in an entirely new HVAC system. He clearly explained the various options for different units, as well as rebates and how to finance our replacement. He also gave us some valuable additional recommendations for how to improve our heating and cooling systems, including some structural changes to our home that will make a difference. We have nothing but great things to say about ADI and Ronen, and the work he has done for us. We absolutely recommend him without reservation!
The whole process of selecting and installing 2 high-end dual fuel systems for us was top notch! The crew showed up on time, and was professional, courteous, and immaculate. Those systems have worked perfectly for the past 4 years saving us $$$ on our utility bills.
We have used ADI for over 15 years and Ronen is the best. We will never use anyone else. He is professional and knows his stuff. Thrilled to be his customer. You will not go wrong with Ronen and ADI!!
We have been using ADI Heating and Air for years and have always been happy with the services provided. Quality products combined with expert installation & maintenance keep us cool in the summer and warm in the winter.
The team did a fantastic job!! They provided a few options to fix the problem – which was really helpful. I went with a replacement – the difference is so obvious. Quieter and more comfortable. They were really respectful of my time and home. I will definitely go back to them if I ever need anything in the future!! Truly appreciated
Excellent workmanship Very skilled and professional staff. Just update my HVAC system, they installed last one 20 years ago and not one single problem. I would recommend them.
Excellent and friendly service! My Heating was not working properly. I called ADI and he arrived within an hour and fixed the problem in 30 minutes. A++
Our recent experience with ADI Heating & Air was terrific. The owner prepared the estimate personally and gave us a detailed written quote shortly after his visit. He was very responsive in answering all our questions. Once we signed the contract, he oversaw the installation of our new HVAC system himself. His employees were professional and hardworking. We love our new system. We will use ADI in the future for all our HVAC needs.
I wish I met Roman from ADI years ago. Not only he is professional, smart, and helpful, he knows what to do and what not to do. I had an addition put onto my house and they replaced the heating and AC unit 4 years ago. The installation was poor, cut corners, and I have had issues every year. A friend of mine introduced me to Roman from ADI and he has been the first person to figure out what is wrong. He doesn’t do patch jobs, he fixes the root issue. I am confident that if you meet Roman from ADI, you will trust him as I do and know that he is leading you in the right direction. There is no one better in the area who works on HVAC systems. Thank you from the Wise family for your awesome service and support.
ADI provided immediate assistance on a Sunday. Ronen got my home AC system back online. Very happy with the service and professional technical skill it took to diagnose and repair my AC.
