Mandeville Commercial HVAC Services

Servicing Your Business's AC & Heating Systems

Are you experiencing issues with your commercial HVAC system that require professional repair? At Nu-Air Heating & Cooling, LLC, we have more than 20 years of industry experience, providing effective HVAC services to owners of light commercial properties.

 Our Mandeville commercial heating and AC team knows that problems can be extremely inconvenient for your business, which is why we work hard to be available when you need us most. Whether you need minor repairs and maintenance or a full replacement of your existing system, our family-owned and operated company is only a phone call away.

When you reach out to us for help, we take time to understand how your building is used, how many people occupy the space, and the comfort issues you face during our hot, humid Louisiana summers and cooler winter months. This allows us to recommend the right equipment size, airflow, and control options so your system runs efficiently without wasting energy or causing hot and cold spots. As a commercial HVAC company, we can also coordinate work around your business hours to minimize disruption for your staff and customers while still delivering thorough service.

Because commercial properties in areas like Mandeville, Covington, and the rest of St. Tammany Parish must meet local building and mechanical code requirements, we also pay close attention to proper ventilation, fresh air needs, and safe equipment clearances. We can walk you through general considerations related to code compliance, indoor air quality, and long-term operating costs so you can make informed decisions when planning repairs or replacements. Our goal is to keep your systems dependable and efficient, so you can stay focused on running your business.

Hear From Our HappY Customers

    I trust Edgar.
    “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.
    Immediate & honest service.
    “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
    I know we're in good hands!
    “Edgar Mejia and Nu-Air have gone over and above in catering to our HVAC needs on the Northshore. As a Property Manager with a new property in Mandeville, it's great to have such an efficient, attentive, and reliable company on our team! I know we're in good hands!”
    Ruth W.
    I love their hassle free process.
    “Amazing customer service! I love their hassle free process. Definitely recommend them!”
    Anna
    Edgar is truly a dedicated and rare find.
    “Finally, after 4 years of dealing with incompetent air conditioner repairmen I have found a truly knowledgeable technician in Edgar Mejia, owner of Nu-Air Air Conditioning Repair.”
    George H.
    The crew was polite, clean and well presented.
    “They are extremely professional and knowledgeable. I was very impressed with their extensive knowledge of the unit, product and professional standards. The crew was polite, clean and well presented. They were even the lowest quote but provided thorough knowledge that exceeded their competition.”
    Denise
    Edgar is the kind of man that makes the world a better place. He made me a lifetime loyal customer in one visit.
    “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
    The quote he gave was half the price I'd previously been quoted.
    “When he first arrived, he was able give me a quote for a broken coil and added some Freon to the system as a quick fix. The quote he gave was half the price I'd previously been quoted. On top of that, the other company didn't even bother to temporarily fixing the issue, which was a big deal because air conditioning is all about comfort.”
    Ronnie
    If there were more stars, I would give them.
    “If there were more stars, I would give them. Edgar and his assistant worked from 9:00 in the morning until 5:00 in the New Orleans heat to get my OLD unit working like it was new. They did an excellent job and were so courteous. AND, not only cleaned up there mess, but made sure the floor was swept better than I could do. I would DEFINITELY recommend them to anyone.”
    Stanley D.
