I love working with DNA Heating & Cooling! Andrew is fantastic—he really knows his stuff. He's professional, always on time, get the job done and incredibly reliable. I'm a property manager for 68 units, and he services our building monthly. It's been a smooth experience every time. Highly recommend!

Andrew and his crew are fabulous! They all have a desire to do the best work possible and make sure you are completely satisfied. Andrew is very personable and honest not overselling his services like other HVAC companies. Their pricing is extremely fair and reasonable and the work is excellent. There is no need to waste your time with other companies. I live in condo building and 2 other owners who used him are also happy. I will be recommending them to all my friends and family without hesitation.

Andrew, Bruce, and Jacob at DNA Heating and Cooling were amazing! They were punctual, honest, and extremely diligent in fixing our AC drain issue. They went above and beyond to make sure everything was perfect. They didn’t just fix the issue, they made sure everything was running smoothly and even took extra steps to prevent future problems. Their professionalism and commitment to doing the job right is rare these days, and I am truly grateful for their outstanding service. I highly recommend this Company and their professional team!

Paid $1500 for drain job on our hvac system the previous folks of our place didnt do. Our ceiling was low so they had to make a makeshift drain. Overall the job was done and it works. Its not the best job, but it does work.

Gas Furnace / Forced Air Heating System - Repair
Our experience with DNA was excellent. As soon as I contacted them, Andrew called and visited us. He quickly inpected our attic, which had had a major rat infestation and extremely old heater ducts. He gave us a reasonable estimate for cleaning and sanitizing the attic, replacing the old insulation, and installing new ducts. The crew of Ivan, Andrew, Amanda and Denicio worked quickly and were very personable, reliable and efficient. They kindly removed all the old boxes stored in the attic which was not part of the original work. We especially liked that Andrew followed up with us after the job was completed, to ensure we were satisfied, and offering to come and fix any problems we might have. We could not be happier with DNA and highly recommend them for any heating issues.

Andrew came to my house same day I called. Kept me apprised of when he would be here and arrived right on time. Very courteous and careful. Did great work. Price was more than fair. I thought his work would cost much more. I will definitely use him again should the need arise.

Worked with Andrew. Had an excellent time talking about my goals for the project and he gave me a couple options. He recommended some additions that were very relevant and not upsells. The crew that arrived was great and finished their work quickly. They cleaned up well and I canâ t tell they were ever here. Andrew was on site at the beginning to brief the crew on the job. I had an opportunity to make sure that the scope of work was understood and my questions were answered. Iâ m so happy to have a new contractor to rely on, theyâ ll be doing my hvac work going forward.

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.
