Our History

First Response was founded in 1999 by owner Ivan Rosas. With a decorated career in the HVAC industry, Mr. Rosas gained valuable knowledge and expertise before deciding to launch his own company to serve Yorba Linda and the surrounding community. Over the years, First Response has been able to assemble a strong team of licensed technicians who are dedicated to solving any problem no matter how complex. 

Some of the reasons we stand out and have lasted so long:

  • Fast response times
  • 24/7 availability 
  • Safety first approach 
  • High-quality equipment used 
  • Exceptional service at competitive rates 
  • Friendly and professional staff
  • Licensed and experienced technicians 

We call ourselves First Response because we want to be the first company that you think of when your indoor comfort has been compromised. You can rest assured that we will respond swiftly to make things right. For over two decades we have been serving Orange County and finding the perfect solution for your home or business HVAC needs and don’t plan on stopping anytime soon.
