Mandeville AC Maintenance

NATE-Certified Service for Residential & Light Commercial Systems in St. Tammany Parish

Mandeville summers push air conditioning systems hard. Temperatures regularly climb past 90 degrees Fahrenheit, and the humidity never lets up, which means your equipment runs longer and works harder than it would almost anywhere else in the country. At Nu-Air Heating & Cooling, LLC, we provide air conditioning maintenance in Mandeville for homeowners and light commercial clients throughout St. Tammany Parish, including Covington, Slidell, and Madisonville. Our NATE-certified technicians service all makes and models, and our founder brings over 20 years of hands-on HVAC experience to every job we schedule.

Call us at (985) 288-2445 to schedule air conditioning maintenance or enroll in a maintenance plan.

What Regular AC Maintenance Does for Your System

A central air conditioning system is a significant investment, and scheduled maintenance is one of the most reliable ways to protect it. Some manufacturers require professional maintenance to keep the equipment warranty in effect. Even when it isn’t required, preventive maintenance supports better performance and helps catch developing problems before they become costly repairs.

Schedule regular preventive maintenance to enjoy:

Some tasks, like changing your air filters regularly, are easy to handle on your own between visits. A full inspection and tune-up, though, requires a trained technician with the right tools and diagnostic experience. Our NATE-certified technicians complete ongoing training to stay current on advances in equipment technology, so they’re prepared to service all types of equipment regardless of brand. Members of our maintenance plans also receive a 10% discount on all parts and labor, along with priority scheduling for any repairs that come up.

Maintenance for All Equipment Brands in Mandeville

We offer comprehensive air conditioning maintenance for Mandeville and the surrounding St. Tammany Parish area. Our comfort team inspects the full system, not just the obvious wear points, so developing issues can be identified before they turn into breakdowns.

Our maintenance service includes:

  • Inspecting and adjusting the thermostat
  • Fully checking all electrical components
  • Air leak inspection
  • Drain line blowout
  • Cleaning the evaporator and condenser coil
  • Inspection of the blower motor assembly
  • Refrigerant pressure monitoring
  • Compressor voltage and amperage check
  • Inspecting and adjusting all other working components

If a problem is discovered during the visit, our comfort team explains what was found, what repair is needed to help prevent a breakdown, and provides a quote before anything is scheduled. No surprises.

A Maintenance Schedule That Fits Your Needs

Most equipment manufacturers recommend professional maintenance at least once a year. We recommend twice-annual visits: once in the spring to prepare the system before peak cooling season, and once in the fall to confirm everything held up through the summer and is ready for any remaining demand. That second visit matters here in St. Tammany Parish. The cooling season is long, and systems accumulate more annual run-hours than they would in a more temperate climate.

We offer several maintenance plan options to fit different equipment needs and budgets. One-time maintenance services are also available for clients who aren’t ready to commit to a plan, and we can build a custom plan around specific requirements. Plan members receive a 10% discount on parts and labor and priority scheduling for repairs throughout the year.

To enroll in a maintenance plan or schedule a visit, contact us online or call (985) 288-2445 to speak with one of our comfort team members.

    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.
    They are reliable, the work was done when promised and they cleaned up the work area.
    “Edgar and crew installed a new electric panel at my house, they also moved a/c return and a few other things. They are reliable, the work was done when promised and they cleaned up the work area and even swept my floor. Thanks for the great work.”
    Lorena
    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
    Professional, knowledgeable and most of all very honest.
    “The owner, Edgar, repaired my a/c. He was very professional, knowledgeable and most of all very honest. I highly recommend using NU-Air for all of your heating/cooling needs!”
    Michael
    I tried 5 different HVAC contractors over 24 years in this house but in the future I will call Edgar Mejia first.
    “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
    Fantastic service
    “Fantastic service, amazing attention to detail, very honest!”
    Wayne A.
    Thank you Edgar!
    “He really took his time explaining all of its features and what to expect from him and his service team.”
    Elizabeth G.
    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!”
