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.

    I would definitely recommend Edgar and his company to friends and family.
    “Everything was amazing. The time it took to the service I would definitely recommend Edgar and his company to friends and family.”
    Lydia
    A master of his craft.
    “He is a truly honest person. He was the head mechanic at his previous company and everyone I know went to him. He is always on time, polite, and extremely professional. His work ethic is phenomenal, he will make sure everything is correct and he never disappoints. He will always tell me exactly what the problem is and never tries to sell me a new unit or part that I don't need. He cares about his work and his clientele. He is well educated in the HVAC field and a master of his craft.”
    Donna C.
    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
    Edgar went above and beyond my expectations in his service.
    “Edgar does Fantastic work! My employer had us get three price quotes on the work to be done at our store. NU Air gave us a more than fair offer to perform the work. Edgar went above and beyond my expectations in his service. In fact he was out in the rain installing our roof mounted Central Air! Thank You! I would highly recommend NU Air for commercial and residential.”
    Lee A.
    He has been taking care of my family's heating and cooling needs for years.
    “Edgar is fantastic! He has been taking care of my family's heating and cooling needs for years. I am not an easy customer, as I am very particular with how I expect things to be done. Edgar continues to exceed my expectations! Today he performed the seasonal maintenance for both the upstairs and downstairs units. In addition, he installed the REME-HALO Advanced Environmental Air Treatment System on both units. Edgar recommended this to us, as we have two dogs, two cats, and a rabbit (a lot of paws per square inch in our CBD residence)... The installation was very clean and seamless. The condo already smells better/cleaner (no pet odor at all), and my son's allergies seem much better (no sneezing, no coughing)... Edgar even took the time to register the purchase with the manufacturer to satisfy the warranty requirements. That is service above and beyond! Extremely profession, knows his craft, and always honest... Please do not hesitate to message me, should you require more detailed information. I highly recommend NU-Air Heating and Cooling!”
    Michael B.
    Extremely knowledgeable, professional and very honest!
    “I spoke to Edgar on Wednesday a.m. , explained we were told we needed a new HVAC system. I felt a second opinion was needed. Edgar scheduled to meet that afternoon. After checking the system, he immediately told us the furnace was very good and did not need replacing, he expected it would survive at least another 10 years. He explained a/c problems and they could be repaired with parts . Due to cost of replacement parts and age of unit, we felt it prudent to replace instead of repair. We discussed the brands we were interested in. Edgar had tremendous knowledge on each brand and was thorough in his explanation of each. He didn't try to rush us through our questions. Later that evening he sent quotes on the four we spoke about. The prices were very fair. His crews were booked through mid part of following week. During our initial conversation, I mentioned we had out of town guest coming for the weekend. He was concerned and said he would come by Friday evening or Saturday a.m. to add Freon to get us through the weekend. Thursday evening Edgar called to say he had our parts and he would install Friday morning! We were very happy and impressed that he was concerned for our comfort and weekend company. Edgar completed the job mid afternoon. He left the house immaculate and the house is cool again! He is truly a professional and a great guy. Very happy we found Edgar and we highly recommend Nu-Air!”
    Sherry
    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!!”
