Neighbor had National Air replace their system and mentioned how smooth it went. We were on the fence about replacing ours but when it finally gave out in July, we called them first. Quick quote, fair price, system installed within a few days. No regrets.

Reviews
Tech came to look at a unit in our duplex in the Marigny. Older system with some non-standard ductwork modifications. Assessed it without immediately jumping to replacement, found the actual cause of the problem, and fixed it same day. That diagnostic approach is what keeps us coming back.
National Air came out quick, and all the personnel we've dealt with are courteous and professional. They are informative and feel trustworthy. We've recently dealt with some shady sales pitches and information (and not great maintenance calls) from another a local company, and National Air really helped us out. I highly recommend them from their recent services.
