Air Tech is a great, family run company dedicated to fast, fair and friendly service. I've referred them to my clients and neighbors and today I called on them to repair my own air conditioning system. They diagnosed the problem quickly, picked up the part and came back to fix my system!

Excellent service. Our A/C went out and the service technician was out to our house the next day. The motor on the compressor went out and the part had to be ordered and was replaced within a couple days. The tech, Isaiah, was very knowledgeable and efficient.

Very “on the ball” company. They came out to give me an estimated on a new unit for my house. It was the most affordable of all of the companies that I spoke to. They were at my house exactly when they said they would be and explained all of my options. I will be hiring Air-Tech to install my unit.
