Thermostat Installation Companies in Santa Monica, CA

"Shai was super professional, extremely courteous, and very well prepared with a thermostat to fix my faulty heating and A/C system. I am very grateful for his prompt response and clear communication. I would not hesitate at all to 100% recommend Shai."

"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."
