    Great work. They found the outside air conditioning unit needed a capacitor changed. Quick and inexpensive. I'm very happy with their work.

    5.0 Kris M. Madison, NJ

    I was fortunate enough to come across JJ Air Plus for a hvac replacement. Juan was very courteous and professional from start to finish. He made the whole process of updating my hvac system extremely easy. Juan was quick, reliable, and honest. So far I am very pleased with the new system and most importantly finding JJ Air, which will be my new go to company from now on.

    5.0 Doug H. Florham Park, NJ

    Neat and clean during and after the installation of the condencer and evaporator/blower.

    5.0 Carol R. Fairfield, NJ

    I needed to replace my old compressor and coil. Juan responded immediately, came the next day and gave us the best options. He was courteous, friendly, very knowledgeable, and explained everything so we could make the best choice. He was very honest about what we actually needed, gave us a very reasonable quote, and was very fair about payment options. He came on time the next day and finished the installation in a few hours. He and his men were neat and efficient. They even cleaned up some things left undone by the previous contractor! Juan is an honest, trustworthy professional who does outstanding work - on time with no hidden extras - at a very fair price. I am so happy I found him and highly recommend this company.

    Juan replaced HVAC (22yrs old) when it stopped last Oct and today replaced my water heater (10yrs old). He is on time, responsive and does a clean job. Also, give you tips on keeping up with maintenance and doesn't not add any hidden items when job is being done. Always followed up next day and made sure I register product with serial numbers for warranty

    5.0 Jeyson Z. Boonton, NJ

    I needed to fix an A/C. Juan was very courteous and showed up the next day. He started to give options, always trying to look out for his customers to give the best / cheapest price. I’m glad there’s still some people that really care about giving the best service before anything else.

    5.0 Tom S. Morristown, NJ

    Wonderful experience. Honest, showed up early and did high quality work!

    5.0 Bob M. Mount Tabor, NJ

    I needed a new compressor and coil installed to repair my aging central air system. Juan was prompt, adapted his schedule to get my project done quickly, gave a reasonable quote and got the job done with no extra costs. He was on time and within budget, and the system is working perfectly. I will hire him again as heating season approaches to install a humidification system. Happy to have found JJAir Plus!

    Very fast , very professional .

    5.0 Jian W. Flanders, NJ

    My AC unit stopped working during a heat wave, I called Juan in the morning and he came to my house early in the afternoon. Juan fixed my AC unit within 10 minutes, he did not try to tell me to replace anything unnecessary, gave me an estimate if I want to replace the whole AC system. The price was very reasonable for the repair work. We sat down and chatted a little afterwards, Juan is very friendly. If you look to get any HVAC work done, look nowhere else, Juan is the one.

    1. Verify Trade License
      HomeAdvisor checks to see if the business carries the appropriate state-level license.

      As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

      We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
