"Air-Tech installed a 3 zone Mitsubishi mini-split system in our home this in September. We got quote from five companies for the system and decided on Air-Tech because of Larry’s knowledge and experience. The bid from Air-Tech was competitive. Air-Tech was not the lowest priced bid we got, but quality is worth paying for. I can say that out of all the HVAC companies we have worked with over the years Air-Tech surpasses them all by leaps and bounds. When I say this, I am coming from a place of experience. We have built our own house and we come from a family of architects and builders. We also had just finished working with another company (that shall remain un-named) around the same time to replace a different central air system. That other un-named company completed the job late, charged a higher price than what they proposed, and left our house and property a mess. Air-Tech however was knowledgeable, prompt, clean, trust-worthy, and professional. Larry even went out of his way to get our project done faster than their schedule should have allowed at the time. They were scheduling months out when I called during the big heat wave of the summer, but he got our project done in three weeks anyway. I had explained to Larry that we were without heating or cooling at the moment and really needed help. I did not tell him that the urgency was because my terminally ill mother was coming to stay with us and she needed good climate control. While Larry didn’t know about my sick mother, he was able to understand the urgency in my tone I suppose. Larry put an extra crew on the job and oversaw the work himself. The fact that Larry came through for us made such a difference in our lives at the time. I am sharing this story to demonstrate that at the end of the day Air-Tech is a company of people who want to help people and on top of that they are excellent at doing what they do. PS. I also enjoyed the Holiday Card they sent us this year."

"I had AC Dave preform three jobs for me over the past few years. (1) New ducts a few years ago. (2) Installed a mini-split heat pump in master bedroom this year. (3) Then a few months later I had him remove my old Central AC and replace it with an 18 SEER heat pump and new coil, all the while leaving my old furnace in place as a back up. Dave and his guys did a great job on all three projects, completing each one in a day. Highly recommended."

"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left. "

"My field technician Leath was prompt on time and highly professional. The services were conducted swiftly and Leath was very knowledgeable and gave me a honest assessment of my unit. He provided me with excellent options for continued service and gave me estimates on the cost of replacing the unit would be and what the trade offs of continuing service or replacing would be."

"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."
