"Got referred to this business from a friend when I had issues with my furnace. They were able to inspect, find the issue, give me an estimate, and fix the problem as soon as I agreed to the work all in the same day. I would recommend them to anyone else having problems with their HVAC system."

"When my heating system broke, multiple HVAC companies quoted me outrageous prices for parts. However, Andrew and Daniel quickly identified the real issue, which was a connection problem, not broken parts. They explained everything thoroughly, fixed the issue promptly, and charged a fair price. I definitely trust their skills and highly recommend them!"

"My AC was leaking in my bathroom so I was looking around for someone reliable to come fix it without charging an arm and leg. Was referred by a friend to Yang's Mechanical - the guys were on time, professional (they brought their own shoe covers!) and identified and fixed the issue very quickly. Would highly recommend to folks in the LA/OC area for any HVAC issues if they're looking to support a small, trustworthy local business."

"Had an amazing experience with this business! They replaced our entire downstairs AC unit, and the entire process was seamless from beginning to end - from walking us through the installation to completing it in just a few hours. The AC is working great now and we finally wont be melting every summer!"

"Always hard to find a reliable refrigeration company. Glad I came across these guys, very knowledgeable and don't try to upsell you. They also follow up with you as most don't. Highly recommended to anyone!"

"Excellent service! Thank you Yang for providing quality HVAC services. It's so hard to find a responsive and reliable company. I called several different places and they said they would get back to me, but never heard back. Yang called me personally and came out the same day. He checked out our furnace which was blowing inconsistently to each room and he pointed out that they had built it inefficiently and had vents going out from the side instead of from the end where the air was directly blowing out from. He said can do a complete overall which would have cost more or he could adjust the dampers and redirect the air for cheaper. I really liked that he gave me options and didnt just tell me that I had to do the more expensive thing and had no choice. I am a real estate broker so I know its hard to find a company that really tries to help you and not just trying to make the most money they can. We went with the lower cost option for now and its working great. I will definitely keep Yang's Mechanical in my phone and tell my clients about him.!"

"So happy and relieved that we found this company. Our heating system was not working well and the thermostat needed to be replaced. We got quotes from several places and Yang's was the most reasonable, plus the way they explained to us what needed to be fixed was simple and straightforward no upsell on any services we didn't need. Our home is wonderfully comfortable now and I love the new thermostat. Thank you Yang's Mechanical for your professionalism and your honesty, and for sincerely caring about your customers."

"Outstanding experience with Yang’s Mechanical. Andrew was able to schedule us on the same day I called. He was professional, prompt, and very knowledgeable. From the initial consultation to completion of the work, the service was very smooth and top notch. He explained everything very clearly and make sure our AC work probably before leaving. The price was much cheaper than the other two quotes I received. I highly recommend them to anyone needing HVAC service."
