They showed up on a Sunday at 3pm, which is impressive. The technician arrived promptly an hour later with the exact part I needed, which I already knew was a replacement. They did the job flawlessly the next day. Out of four quotes I got, theirs was the most competitive. The work was spot on and they ensured both units were working properly. I'll definitely hire them again for any future AC needs or new installations.

Our air conditioning unit stopped cooling. I reached out to National Air Conditioning on a Sunday morning, and George showed up that afternoon. He was very professional and diagnosed the issue as needing new AC coil replacement. The next day, he returned with his team to swap it out. They worked quickly and left everything spotless.

We're thoroughly pleased with National Air's service. Mr George Karumathy arrived promptly within the hour of us calling on a Saturday, which was impressive. Our air conditioning units were installed by another company in 2023, but they didn't do the job correctly - we had a leak that caused our upstairs unit to overwork and lose refrigerant. Mr George quickly diagnosed the issue and fixed it in under two hours, welding the copper coil to stop the leak and adding new refrigerant. His price was fair considering the extra work involved. After he finished, our upstairs unit went from running non-stop for 14 hours a day to about six hours a day. We'll definitely be calling National Air next time we need AC maintenance.

The technician, Thomas, turned out to be knowledgeable, friendly, and got the job done swiftly. My experience with them was overwhelmingly positive from start to finish. They grasped the severity of the situation, especially during Houston's sweltering summer months. Thomas diagnosed a leak in my evaporator coil and promptly ordered the necessary parts, with his team installing it the following day. Given their pricing was very reasonable compared to competitors, I'm glad I went with National Air Conditioning.

Fast and efficient service at a fair cost. The technician who fixed our AC was knowledgeable and offered helpful tips for maintenance. He even worked on a Sunday, which was convenient since it coincided with church services. Overall, great experience. Highly recommend National Air Conditioning and the person who served us.
