DNA Heating & Cooling, Inc.

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!

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!

Bruce was great - friendly, knowledgeable, punctual, communicative, fast and great with kids (just an added bonus when you have babies and toddlers running and crying through your worsite). I recommend DNA to everyone that asks! Ours was a huge fire risk that required a new motor and electrical. Bruce didn't try to upsell; he tried fixing it without a new part, explained it all to me, showed me what he tried, but it didn't work. It feels so good to work with an honest team!

Andrew came out today 11/21/25. I have to say top notch service. He was able to get our heater working the way it used to. He was very knowledgeable and even gave me some extra pointers. I would recommend anyone who needs their heater working for these So.Cal cold nights or the blistering heat in the summer, DNA Heating and Cooling is the way to go!! Their logo says it all because HVAC is in their DnA!
