I got quotes from several HVAC contractors to replace an old system, and National Air stood out immediately.Roy Calante did the most thorough inspection by fargoing into the attic, tracing every run, and catching an access issue the others missed. He included the fix in the scope without me having to ask.He spent hours ensuring the system was properly sized and came back the next day to walk through the quote and technical details in person. It was only after that visit that I learned he was the ownerhe never mentioned it. He later reviewed the contract with me line by line over the phone until I was completely comfortable.The installation matched that same level of quality. Daniel and Simon did a fantastic job. They completed everything in a single day and went above and beyond to ensure it was done properly. Jony, the Quality Control Manager, followed up with a thorough inspection, confirmed that the job was completed to high-quality standards, and offered helpful recommendations to keep my unit running efficiently for years to come.Maria, the project manager, kept everything running smoothly and coordinated all the moving parts behind the scenes.Across the entire team, the professionalism, communication, and attention to detail were exceptional. Its clear they take pride in their work and are committed to delivering a high quality experience for their customers.If youre in the market for a new HVAC system in the New Orleans / Metairie area, National Air should be your first choice. Ask for Roy.
