What our clients say about us!

  • I would like to recommend Harold from Unitech Air Co. extremely highly! Not only does he do an excellent job, but I have had to call him on a Sunday evening and he comes out and fixes the problem immediately. I have already referred him to many friends and family. Thanks so much for being there!

  • In December of 2007 I had an air conditioning unit installed in my house by Unitech Air Co. The company was recommended to me by a friend, who is an air conditioning professional. I myself cannot recommend them highly enough. The work was completed promptly and with great professionalism. My unit was not easy to install since it had to be placed on the roof. My garden is heavily wooded and we needed the help of a crane. The crane company Mr. Diaz hired was extremely careful with my plants and did not damage my garden at all. We are very satisfied with the service Unitech Air Co. provided us. On a scale of 1-10, I would definitely give them a score of 10.

  • Living in South Florida, we tend to take our air conditioners for granted. When we moved into our house several years ago, we couldn’t figure out why our electric bill was so high, and why our bedroom always seemed to be at a different temperature than the rest of the house. Our old unit broke down a few times and I’ve always relied on Unitech. Unitech has always responded quickly and efficiently to our calls. Eventually, Harold performed a complete replacement of our entire A/C system, the positive results were dramatic. The installation and workmanship of the ducts is superb and the Trane CleanEffects filter system that he recommended has helped relieve many of our recurring allergies. Our bills have gone down and our comfort level has gone up. It doesn’t hurt to know, that if anything goes wrong, Unitech will be there. Unitech’s professionalism, customer service standards and integrity make it a few cuts above the rest.

  • We have used Unitech Air Co. for our air conditioning needs for many years. Their personal, professional, timely and honest way of working and conducting business has made our lives easier than ever. Living in South Florida, you need a reputable company like Unitech. I highly recommend them for your air conditioner needs.

  • I have been using Unitech Air Company for about 1 year and am extremely satisfied with the service. I have called at night and on weekends and received a phone call back within 30 minutes. The service on my air conditioner was fixed within hours. I recommend Unitech Air to all my friends.

  • Two years ago, a construction project at our home offered us the chance to relocate our 10-year old A/C unit. A friend recommended Unitech Air as a new company with customer services and cost savings priorities. They evaluated our system which worked well, but wasn’t efficient. Instead of relocating, we installed a new, energy-efficient Trane system that featured better control of humidity levels in the home, making it feel cooler at the same air temperature. After about a month of usage, they then helped “tweak” our A/C’s performance settings, and instructed us on basic, easy homeowner maintenance. We now have experiences two years of reliable indoor comfort as well as lower costs of operation. Unitech did our job faster, better, and cheaper than we had expected. We are entirely satisfied, and will continue to do business with them.

  • We needed new air conditioning in our older home last year. Good friends recommended Harold Diaz and his company. From the first visit/estimate to the last days of installation, it was one of the most professional, competent work experiences we have had in Miami. Harold (and his people) are reliable, knowledgeable, fair priced, on time and extremely hard working. (Actually going above and beyond by staying later than contracted and cleaning up after themselves!)

    Our friends did us a service by recommending Unitech and I would not hesitate in doing the same for anyone needing Air Conditioning Sales and Services. Miami needs more decent, reliable companies list Unitech. Good luck.
