At Titan Air, we’re more than HVAC technicians. We're part of the community. Founded by Mark Fisher, a La Mirada local who still answers phone calls and checks in on jobs, Titan Air was created to bring neighbors the kind of service he’d expect for his own family. When your comfort is on the line, you deserve more than quick fixes; you deserve expertise with heart, and that’s exactly what we deliver.

FLEXIBLE FINANCING? ABSOLUTELY

Whether you're trying to beat the summer heat or warm up on a chilly winter night, our team is here to keep things running smoothly, efficiently, and reliably. No gimmicks. No runarounds. Just honest work, done right.

We Care

At Titan Air, giving back is part of who we are. With every installation, repair, or tune-up, we support causes close to our hearts, locally and nationally. We partner with organizations like Habitat for Humanity and MyFace, which helps children with craniofacial conditions. Because serving the community means making a difference, one good deed at a time.

The Titan Air PROMISE

We’re committed to your 100% satisfaction. It’s not a catchphrase, it’s how we do business. Our values guide every job:

  • Be completely honest, every time

  • Support our communities

  • Always do the right thing

  • Leave every customer smiling

If that sounds like a good fit, we’d be honored to serve you. But if you’re looking for shortcuts or sales pitches, we might not be your crew. We’d rather lose a sale than lose your trust.

“...He came out to our house at 8:30pm in a Friday night when it was still 100 degrees and got us up and running in no time. He was straight forward and honest throughout the process. I received text messages for when he would would arrive, when he was in route, when he was finished with the job, when the invoice was available (exactly the quoted price he gave up front), was able to pay via credit card on my phone, received an email receipt and couldn’t be happier. This is how a business should be ran! Will recommend him to everyone I know.”

“We had an ongoing issue with our air conditioning that 2 other HVAC companies could not fix. Chip came out and diagnosed the problem (float valve) and had it fixed within an hour.
This company is different. They are truly professional.
Setting the appointment was easy. I was sent email confirmations, arrival status updates and a payment receipt. ”
— Dave C. (YELP)

“Did not want to bother you during your vacation, I just wanted to let you know your installers were awesome, they have the white glove down to perfection. They were on time, respectful and totally cleaned after themselves. Patient with me trying to install app on my phone. (I still have to learn how to schedule) but I can access and turn temperature up and down. I was impressed and I am demanding!”
— Maggie Vigil

“Excellent service. I got an appointment with a tech within two days and Chip was great. He texted me to let me know he was on his way, he was spot on time, explained everything he was doing, had all the needed parts, made countless trips up to the roof unit in our condo, and made the necessary repairs to take care of the problem. Mark was great getting me scheduled so quickly and Chip was outstanding as the tech who solved our problem. I highly recommend this company. Great customer service!!!”
