Get matched with top thermostat installers and replacers in Simi Valley, CA

"We had a new smart thermostat installed. Shai was very flexible in scheduling a visit as we were working around the local fires and the electrical shutoffs. He arrived on time, made the installation in the time allotted and helped us set up the app on our phones. We also discussed some future maintenance needs and will be scheduling when the time comes. Very reasonably priced. I would definitely recommend this company."

"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."

"My wall heater had not been working for 3 yrs and I could not find anyone to fix it. This young man and his brother came out when I called checked out my situation and explained everything to me and my husband. They were very knowledgeable and professional came out the next day on time and replace my whole heater. They protect my floors, cleaned up and now my home is warm and the new heater looks great."

He’s now my go to guy for any and all AC & Heating issues. Oh and he showed up exactly at the time he told me he would. Amazing"
