About Multi Air

Our Story

Multi Air Service LLC is a family-owned HVAC and mechanical contracting company based in Pasadena, California. We've proudly served San Gabriel Valley since 2015, and we're still run by our founder.

Ricardo Ortega didn't set out to run an HVAC company. He actually started out working in the beer systems industry, where he learned the ins and outs of airflow, water-source cooling, and refrigeration equipment.

Watching a mechanic replace a compressor and earn in a single job what Ricardo made in an entire week, he decided it was time for a change. He enrolled at Los Angeles Trade-Technical College, earned his HVAC degree, and became a licensed contractor in 2015. That same year, he founded Multi Air.

In the years since, his company expanded to serve both homeowners and businesses in San Gabriel Valley. We hold a California C-20 HVAC contractor license (#1026812).

Even with our growth, Ricardo still does hands-on HVAC work, rather than staying behind a desk.
