    Technician Abdul was prompt professional and also competent. He insured that He only tackled the necessary issue my ac unit was presenting. I called for service on a Friday and they were available to come out the very next day. I am very satisfied with the company and will assure I use them in the future and refer them to family and friends.

    I called Diagnostic Heating and Air Conditioning LLC company after my house was flooded from top to the basement. My AC was not working and most of my wall sockets weren't working as well.
    The company came out and helped fix all the problems and was kind enough to find someone cheaper to help me with fixing the dry wall.
    Mr Abdul is a good, honest, and reliable man. His service was prompt and professional. I will definitely call him with any future heating or AC services.
    I HIGHLY recommend him to anyone who needs heating or AC services.

    My husband and I were very pleased with the service we received last night. Our upstairs A/C wasn't working properly and we couldn't figure out what the problem could have been. I found Diagnostic online through a simple Google search, called in the morning and was able to make an appointment for a tech to come out later that evening. My husband worked with the techs to figure out the problem, which wasn't anything major, and to also get some solid information on other potential problems we might have with both of our A/C systems. My husband told me he really liked the way the techs worked. They even wore booties over their shoes so as to not track dirt into my house. The cost was minimal, I was expecting a lot more, but was pleasantly surprised. I would recommend this company to all of my neighbors.

    Abdul was very professional and did excellent work. Highly recommended.

  • *****

    After multiple issues with my AC and bad service from other heating and air companies I called Diagnostic Heating and Air Conditioning. My experience with Diagnostic was by far the smoothest I have had in years with any service company. Abdul arrived on time, he was honest about the work that needed to be done and there was no price gouging! Diagnostic fixed the source of the problem and did such a great job that I asked them to come back to do some additional work on another area of my home. I will definitely call Diagnostic again for any heating and AC problems.

  • *****

    I would highly recommend Diagnostic Heating and A/C. I originally used another company that told me I needed to replace my A/C. Abdul was able to fix and save me money, He is very knowledgeable and a great person to work with.

    Abdul came by within 1 day of my request to look at my HVAC..it wash during one of the cold snaps..he arrived on time diagnosed the problem and fixed it with a courteous and professional manner..the price was reasonable and I highly recommend their services

    Abdul was prompt, courteous and professional. He explained what he was doing and made the repairs.

  • *****

    We were very pleased with Abdul. During a very busy time of the cold season, he came late on a Friday evening within the promised time frame after our home insurance provider called several other HVAC technicians who did not respond. He also made no issue about servicing our furnace in the crawlspace after another technician had refused to do the job claiming it is inaccessible. Abdul was prompt, helpful and very diligent and professional in getting the job done. We were very satisfied with his work and the results. We recommend him to others and plan to request his service again the next time we need HVAC work.

  • *****

    very happy with their work and the issue was fixed
