Wayne did an excellent job identifying our AC problem. He went above and beyond to get our Air Conditioner fixed in one day. National Air has installed 2 air conditioning units for us. They do an incredible job installing and are very professional. Roy, the owner, is conscientious and is dedicated to make the customer happy.

Excellent is the word I would use to described this company . They are professionals and does not take short cuts in their installation. I’ve learn a lot about how bad my old unit was as well as how poorly it was installed from watching their 2 best installers(Joel and Oscar) who worked on our house. I like the fact that, whatever price you see on the receipt is what you’re going to pay(no hidden cost). In fact we love the company so much, we ended up changing our 4 central unit instead of just 2 that we originally planned. So If you’re in a market for a new AC, I would highly recommend checking

We contacted National Air over a month ago to look at our freezing air conditioner. At the time they replaced a capacitor. A few days go by and it continues to freeze. We ask them to come back.
The technician spends an hour here and leaves without a plan on how to fix it. I call them the next day and they say they’ll call me back with what they planned to do. After not hearing from them again I call the next day, they say they’ll call back. Before they close I call them again and they tell me they ordered a part that will be here in 3 weeks. I ask them to send a text explaining why they decided

A year ago we purchased an entire TRANE system, including duct replacement. Nothing but problems since the install. They have been out to the house 14 times since installation, fixing various problems. And it is a real struggle to get them out. Currently today A/C is not working again. The owner Roy won’t return our calls but why should he, he’s got our money. You will not be a priority with this company if there are warranty issues.

My upstairs unit isn’t cooling like it should. I called national air because I have used them in the past. Let me say that i called once last week and again yesterday. Have not received any information - a call, an email, text, NOTHING!!! If they can’t find my old quote, the thing to do is call and schedule to come and see the unit again. Apparently my hard earned money isn’t good enough for them.

Worst company I’ve ever worked with. We had an air conditioning unit installed less than a year ago and have had nothing but problems. They have come out to our house 4-5 times and nothing has been fixed. We just keep getting the run around. No accountability whatsoever. The original consultant who gave us his card never answers or returns your calls.

We have been very pleased with National Air in all the years dealing with them. This weekend was especially pleasing when we needed help on a Saturday, while preparing for a large family gathering to take place on Sunday for Father's Day. We discovered a hot downstairs around 11:am and realized no cold air was coming up from the registers. I… called their number and was advised by a friendly call service that someone would be calling to make arrangements soon. In minutes, an appointment was made for that afternoon. Jared came over and identified the problem. He advised us on how to get the
