National Air installed heat and air conditioning in 3 of the 4 units in this raised shotgun double. Christine and Maria, in the office, and Jony the technician, have always given us great service. If we have a problem or need maintenance, Jony can take care of it. Very satisfied. I just wish Freon was less expensive.

We had a great experience with National Air LLC for our air conditioning installation. The team was professional, on time, and very knowledgeable. They explained everything clearly and completed the job efficiently. Our new system works perfectly, and we’ve already noticed improved comfort, especially dealing with this southeastern Louisiana weather. I highly recommend their services.

National Air is wonderful; they installed my new AC unit and ductwork during the horrible summer of 2023. I immediately signed up for their maintenance programs, and the maintenance techs, like Robert, are fantastic. So knowledgeable and helpful. The office staff is an absolute delight as well; I trust them implicitly. Highly recommend!
