What Our Customers Are Saying

  • A military veteran that holds true to his integrity and customer service. Edgar was prompt and honest with us right up front. It turned out to be a simple fix but he did a complete check of both units and didn't try to take advantage of us or our situation. He left us with a lot of knowledge for when the time comes to replace our aging units. Thanks Edgar! Chris|Mandeville, LA

  • Edgar was quick to respond and provided us with options on a new system which were more competituve than the quotes we received. In 36 hours we were financed and cool with a system with the system we wanted for AC and heat. Samantha|Mandeville, LA

  • I called Edgar after 6:00 on a Friday night and he came by immediately and had my AC up and running in less than an hour. He was extremely professional and honest, even reviewing a previous invoice from another company for work that we had done to ensure we hadn’t already for what for he completed. I will absolutely call him again and will recommend him to friends and family. Chrissy|Mandeville , LA

  • Edgar and Nuair completed a new system in my home. Edgar was very knowledgeable, reliable and completed an overview of system ,prior to finishing the complete install. I was very impressed with Edgar, his employees and his company. I would recommend Edgar and Nuair to everyone. GREAT JOB EDGAR!!! Fred|Mandeville, LA

  • As a single mom, one of my biggest worries is being taken advantage of when it comes to home repairs that I know NOTHING about. Edgar is possibly the most honest and knowledgeable professional I have ever met. He not only came the same day I contacted him, but he quickly diagnosed the problem with superior knowledge and skill, and assured me that I did not need a new AC unit when I was convinced I did (and ready to shell out thousands of dollars to replace the whole unit!). I won't even consider using anyone else in the future. The charge for his services were beyond reasonable -- and far less than I've ever been charged in the past. Edgar is the kind of man that makes the world a better place. He made me a lifetime loyal customer in one visit. CMB|mandeville, LA

  • I am a meticulous DIY handyman myself and I was completely satisfied with the work that Edgar did for me. He replaced the evaporator coil, transition, plenum box and first 25 ft of duct for the ground floor system. He also lined (and sealed) the return air passage. While he made several work scope additions during the job, Edgar made no attempt to increase the agreed upon price. Edgar approached my project as if he was working on his own system. I highly recommend this HVAC contractor. Marvin

  • I needed a new a/c for my home. I received 4 quotes and Nu-Air was the lowest. Edgar came out to give the estimate himself and returned the following day to start the install. No salesman. Deal directly with the owner. Probably how he keeps the cost lower. I will need my second a/c replaced soon. I won't shop around next time, I will just call Edgar. Keith D|Mandeville, LA

  • Edgar, the owner, came out originally to diagnose one of my A/C units not working. He quickly diagnosed the problem as a damaged circuit board, which he was able to retrieve from his supplier and replace within a couple of hours. However, while examining the unit, he found that the evaporator coil was leaking. He recommended replacing it, and said he could come out in a couple of days to do that job. In the quote he provided, he included a free charge of freon to the system to get through the next couple of days as long as we used him to replace the coil. In the meantime, I checked pricing from another HVAC company, and it was slightly less than Edgar's quote. Edgar showed up with an assistant on Thursday morning as promised and had the new coil in within about 3 hours. I was very pleased with the work and professionalism. John W.|Mandeville, LA
