DNA is the best company with the best service! They rebuilt my home central air system so it is efficient and I’m saving money on AC and heat. Andrew and Carlos are always responsive and friendly and knowledgeable. They come out for filter changes and they do DUCT CLEANING which is very important in LA after the fires. I could not recommend them more. Hire them, you won’t regret it!
DNA did an amazing job! I needed my older wall heaters updated with a new remote thermostat and they really came through. Very professional and I would recommend them to anyone. Thank you guys! Thomas
Working with DNA was a seamless experience from start to finish. Their communication was timely, clear, and professional. They provided a prompt and transparent quote, ensuring I understood every detail. The job was completed with precision and care, and they went above and beyond to make sure everything was clean and orderly before they left. Their professionalism and attention to detail did not go unnoticed. I highly recommend them and wouldn’t hesitate to hire them again.
The company is reliable, worthy trust. They keep their promise to every detail. Their craft is perfect. The boss and employees are very nice. They answer every question and concern. I paid less than 4 big company quotes and got the best workmen and impeccable installation of a Bosch BVA-36WN1_M-15 . Thank Andrew, Ivan, Denicio and Carlos for their beautiful job.
