I want to acknowledge Ismael and Justin for the excellent job done in my home. I am a 1st time homeowner(woman) and did not have a clue on what could be wrong with my a/c. I was given a professional answer and cause of my A/C breakdown. I felt 100% comfortable with Ismael's recommendation. He was upfront about the cost of repairs, which helped elimintate the factor of surprise. The following day, Justin came to install up-to-date thermostats on both floors of my home.
Having a failed a/c system in the heat of July was unfortunate and at times miserable. DNA helped me get my air back serviceable in a quickly manner. They gave me their undivided attention and made me feel as if I was a VIP client.
Thank you guys ! I appreciate your service. -

WHEN YOU WANT IT DONE RIGHT: There's absolutely no comparisons to the product and service D n A provides. They will always be my GO-TO for my Heating and Air services; HANDS DOWN. My rental property’s utilities were over 250.00 a month on average. I had several companies give me estimates wanting me to upgrade to new equipment, but when D n A came in Ismael assured me it wasn’t an equipment problem and recommended a restructure utilizing the existing equipment saving me 6K easily. After the repair the utilities went from 250.00 a month to 95-110.00 still holding-9 years later.
PHENOMENAL ENGINEERING: now my Home, because of a few bad experiences, I am a hard sell; critical when it comes to spending/wasting money on poor performers. While home in the attic trying to understand why my utility bill was not meeting Georgia Power’s energy costs suggestion, and why we had this sinus pressure and headaches, and the threat of energy cost increasing. Well, I called Ismael and he found the problem. NO LIP SERVICE, he conducted a thorough assessment, calculated the entire house inside and out; from the ceiling’s heights, room size, carpet, or hardwood on the floors, to the number of windows in the house and house humidity; to window R Values, and wait, which way my house faced during utility peak hours…too much to list. He is by far more than a technician but an Engineer. I value his opinion; I know his craftsmanship and what to expect. I made the right decision especially during these unpredictable inflation times.
Before I made this post, I wanted to report some results. I can control my energy usage during peak hours, no nose bleeds or dryness. It sounds a little silly when I can set limits on how much energy the Power company is charging and be comfortable too.
D n A’s service plan with a 10 year full replacement warranty, AWESOME!
