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

    Only person I would ever trust on my systems.
    “He is the only person I would ever trust on my systems. Edgar is incredibly professional, knowledgeable, willing, patient and exceptionally trustworthy. I am in perfect hands with whatever Edgar says needs to be done to any of my 3 systems. When he leaves the house I know he has done the work perfectly and that he has gotten the job done that needed to be done. Working with Edgar is an exceptional experience because he takes exceptional pride in all that he does. And I am not easy to work with.”
    Jackie B.
    I would highly recommend Nu-Air!
    “I would highly recommend Nu-Air! Called them on a Sunday morning when our A/C stopped working and thankfully Edgar came to check out it out. He had the part to us the next morning by 10am. He and Diego worked quickly to get our AC back up and running. They were very polite, respectful and professional! I have learned my lesson, forget the expensive home warranty (that came with the sale of the house) that in the end does not pay for itself. Instead, set up yearly maintenance with Nu-Air at 1/2 the cost of the warranty and catch any issues ahead of time. Thank you Edgar and Diego!!”
    Kelly H.
    Customer for life...thank you.
    “A friend recommended Edgar to me, couldn't do another year without air conditioning. He worked around my hours gave me different options. Very knowledgeable and professional explained everything to me. I decided to replace old system best decision I made!! I would highly recommend him to anyone if you want fast and wonderful service! Customer for life...thank you.”
    Dana H.
    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
    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
    Trustworthy and the only call I would make.
    “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
    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.
    A true professional in our industry.
    “A true professional in our industry. The representative is knowledgeable,informative, and a pleasure to do business with.”
    Mark
    May the forth be with you.
    “My A/C stopped A/Cing on a Saturday. I called Edgar and he arrived first thing Sunday. I watched as he dismantled equipment and diagnosed the many problems. By Wednesday new equipment was installed, my home was cool, and my neighbors likely are appreciating my whisper quiet Trane A/C instead of the beast i had before. Thank you Edgar. Nothing is of course free but spending dollars for quality and tradecraft professionals is money well spent.”
