Mandeville AC Installation & Replacement

Upgrade for Improved Efficiency & Comfort in St. Tammany Parish & Beyond

Louisiana summers are notoriously brutal, as anyone living in the Mandeville area well knows. At Nu-Air Heating & Cooling, LLC, we understand that you depend on your AC system to keep your home cool and comfortable when the temperature rises. If your air conditioner is having trouble keeping up with the demand for cool air or frequently needs repair, it may be time for an upgrade. We offer AC installation and replacements in Mandeville, St. Tammany Parish, and beyond using products from the best brands in the industry.

Our comfort specialists can inspect your air conditioning system to determine if it needs to be repaired or replaced. When the time comes for replacement, we can help you choose the best system for your home and ensure that it is safely installed for reliable performance.

Give us a call today at (985) 288-2445 to have your air conditioner inspected.

When Should You Replace Your Air Conditioner?

One of the most frequent questions our customers ask when there is a problem with their air conditioning systems is when to replace it. Age is one factor when deciding whether to repair or replace air conditioning equipment.

There are five main signs that you may want to consider replacement. These include:

  • Old age – A system that is 10 to 15 years old is near the end of its life and may need to be replaced
  • Frequent repairs – It may be worth replacing a system that is in need of frequent repair
  • Increased utility bills – As equipment ages, it becomes less efficient and requires more energy to operate
  • An expensive repair – Replacement may be cheaper if you are facing a very expensive repair
  • A system that uses R-22 freon – Newer systems do not use R-22 and, while your system is still in compliance, this freon will become increasingly expensive and eventually cost prohibitive

Our NATE certified technicians are focused on keeping you comfortable in your home. We can inspect your air conditioning system, explain the options for repair or replacement, and help you decide if now is the right time to upgrade to a system with better energy efficiency and performance.

Hear From Our HappY Customers

    Superior service!
    “I have an emergency outage. Edgar came right away. He diagnosed the problem and got us working in less than an hour, while testing the system to make sure there were no other issues. Excellent! Thanks again!”
    Mike
    Professional, knowledgeable, fast, great communication
    “Professional, knowledgeable, fast, great communication and the best price. If you want great service this is the place.”
    Jeff M.
    I have stuck with him as a loyal repeat customer.
    “I was referred to Edgar by my sister over 7-8 years ago. At that time he was with a larger company and I began to request him and him only to come out and service my A/C. He recently branched out to begin his own business and I have stuck with him as a loyal repeat customer. He is always on time and easy to get a hold of. I appreciate his honesty more than anything. He is very thorough in his work, he won't just come in and look at one thing, he will survey the entire unit to make sure everything is working properly. I would highly recommend him!”
    Ronald
    Great service, lowest price and easy to work with.
    “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.
    USE THIS COMPANY ONLY IF YOU WANT EXEMPLARY SERVICE!
    “Best customer service I've ever received and would never consider any other HVAC service. Edgar is very honest and doesn't try to "over sell" his customers. He was very easy going, said to call him when I made my decision...unlike the other companies that were high pressure sales. Edgar has been in the business for 20 years - his honestly and on-site as a manager service is outstanding. USE THIS COMPANY ONLY IF YOU WANT EXEMPLARY SERVICE!”
    Lori B.
    I highly recommend this HVAC contractor.
    “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
    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
    The best service!
    “Thanks NU-Air Heating & Cooling, LLC and Edgar Mejia for your quick, reliable service, expertise and professionalism installing my new AC/heating unit. So happy I had someone I could trust to do the job while I was at work.”
    Peggy
    I love their hassle free process.
    “Amazing customer service! I love their hassle free process. Definitely recommend them!”
