Get matched with top thermostat installers and replacers in Van Nuys, CA

"Service was great and pricing very competitive. Nick Knuth was very knowledgeable when he came to do an assessment of the work to be done, and answered all my questions I'm a very clear way. The techs worked pretty quickly and efficiently when installing the new unit. Deisy and Emma from the office always made sure that things were taken care of and went above and beyond with follow-ups and updates. I would definitely recommend them to anyone who needs this service."

"Guillermo replaced our HVAC unit (heat pump and condenser) several years ago. He also recommended a particular app that controls the thermostat and room temp sensors to control the temperature in varying rooms. He has a great personality and very competent. He is now my goto guy for all HVAC services."

"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 thermostat stopped working and I thought that was all that needed replacement - but the tech tested it and found the drip drain was clogged which turned off the thermostat. He cleaned it out and I had him replace the thermostat anyway. He did a great job and cleaned up afterward. He showed up on time. He explained all work & quoted price before completion. All working great!"

"They did a great job! They were able to guarantee me the job being done 100% and they did just that. They also went out of their way to assist me in minor replacements of bulbs. Definitely would hire them again. Very professional and their time management is on point."

"I was satisfied with their work, but I felt they really were unfair and excessive with their pricing. I was told their $59 charge to come out would be credited to the final charge. Mind you they replaced a thermostat [which on Amazon was priced at $38]. The gentleman was here no more than 25 minutes. When he handed me the bill I was stunned! It was $269, and that was taking into account I was suppose to receive a $59 credit. So we're talking $328 to replace a $38 thermostat and 25 minutes time. Sharon Davis"

"Marco is amazing. Installed my sink and was kind, thorough and I would hire him again."

"The worker arrived on time. He seemed overwhelmed. He stated: "this is a lot". I explained the projects were clearly listed prior to his arrival. I requested that he place the Ring camera on the garage facing the back entrance. He started muttering that he probably could not do this. I explained there was ample wiring in the garage, He never went into the garage to check. Rather, he placed the camera at the back door, merely replacing the light that was there. I think he spent 5 minutes doing this. This was the most important job. The payment is rigged. It is hourly or half-hourly. The worker obviously worked very slowly, taking 2 hours to replace a ceiling fan, not needing to rewire anything. He added an extra half hour at the end, claiming that he had begun a new half hour (had not). I made the decision not to have him check the gutters, as he very obviously had no expertise."
