My American Standard AC, installed in 2015, stopped working for cooling two weeks ago. I first contacted a local HVAC repair company, which had 5-star reviews across Google. Their guy did appear quickly, but for some reason my AC was back running, so he didnt really do anything. Anyway I paid the visit fee, while he tried to get me signed up annual maintenance plan for my two AC units; but what really made me feel not right is the moment he recommend replacing this AC unit. Two days ago the temperature was in high 80+, the AC stopped working again. So I googled again, and found Duo Dragon. Tyler, the owner of this company, is totally professional and amazing. He arrived quickly and was able to diagnose the root of cause and made the fix quickly. His knowledge, as well as his patience to explain and share detail, is totally awesome and helpful. His charge is fairly reasonable, compared with other vendors. I highly recommend him if anyone need a professional licensed HVAC expert. read more

My home had an early 90s HVAC system that finally gave up the ghost; Tyler Nguyen of Duo Dragon responded the same day I listed my project. He inspected the old system and recommended complete replacement of the old system. He explained what was needed explicitly stating that the old system would be quite more expensive due to the availability of the replacement parts needed. His crew showed on time and went right to work. The cost quoted was extraordinarily reasonable especially considering my neighbor had a similar replacement at several thousand dollars more. I THROUGHLY RECOMMEND DUO DRAGON HVAC. read more

Tyler with Duo Dragon HVAC was incredible! He was able to get our HVAC fixed right when the heat wave hit, and we honestly couldn't be more thankful. Super professional, friendly, and easy to work with from start to finish. What really stood out was his honesty, he gave us straightforward advice about our HVAC system and only recommended what actually needed to be fixed. No upselling, no high-pressure sales tactics, just genuine help and quality work. A huge bonus was that he came out on a Sunday when most companies wouldn't even answer the phone. Highly recommend read more

We noticed a strange smell coming from our vents whenever the AC or heat was running. Tyler came out the very next day for a consultation and took the time to walk us through the entire system and explain how everything works. He was extremely knowledgeable about HVAC systems and provided clear, effective solutions to address the issue. We really appreciated his professionalism and honesty throughout the process. I would definitely recommend Duo Dragon HVAC. read more

Tyler Nguyen gives the personal touch and really knows his stuff. After a frustrating experience dealing with a McHVAC company that tried to oversell us on a fix we didn't need, Duo Dragon was a breath of fresh air. Prompt, honest, transparent. He came the same day, got the job done efficiently and explained everything to our satisfaction. Says 95% of his jobs are fixed on the first visit since he carries most parts on his truck. Highly recommend. read more

He kindly explained the issue and how he was going to make things even better than before, as well as being upfront about the cost. His experience and knowledge are obvious, and he was able to get me back up and running within days. Highly recommended, and will absolutely come back to him in the future. read more

Tyler is the absolute best! He came in and assessed the issue and said what I needed. Something didn't sit well with him so he checked again and found a MAJOR problem with the thermostat (something burt out). Because he did not catch it the first time he ONLY charged me for the original issue he found. I appreciate his honesty and if I ever have an issue again, I WILL be calling him again if needed! KUDOS to you! read more

Refilled old freon. Tyler's a nice guy, intelligent, honest demeanor, knowledgeable, helpful, and conscientious. He was quick to arrive and even though my A/C system is older, he had all needed supplies right on hand, no return trip needed, which I see requires a larger van (more insurance, more gas, more supplies) and yet... the maintenance was at a good price too. read more
