"Their technician, Justin came out and assessed the situation, quickly discovering the true source of the problem: the wire bundle that connects the system with the thermostat on the wall and been chewed through by rodents apparently, and this was causing the system to quit. He offered to replace the wiring and do a service on the roof mounted AC condenser unit, which we agreed to. Total cost was a fraction of what we had paid the previous company to not even discover or fix! We would wholeheartedly recommend the services of this excellent company."

"Air-Tech is one of the most professional companies I have ever dealt with. My first contact with the office was exceptional. They had Jose at my house the next day. Jose did a great job of trouble shooting the problem with my furnace and showed me which part was defective. He had to special order the replacement parts which took a few days. Soon after he left, someone dropped off two space heaters to keep our house warm until the parts arrived. Jose then installed the new parts and checked out the entire furnace to see if there were other problems. He took photos to help show what the problem was. He was efficient, conscientious, polite and thorough. The office staff and Jose kept me up to date on when he would arrive at my home. I wouldn’t hesitate to use Air-Tech again if the need arises. They are top notch. "

"I own a laundry and needed two new swamp coolers. I called DNA and Andrew came out and from our first meeting was very professional. He was knowledgeable and able to answer all my questions which put me at ease. These guys did a bang up job. They were clean and made short work of removing my old units and installing of the new ones. I would highly recommend DNA for future work."
