Multi Air Service LLC

Multi Air Service LLC, founded in 2015 by licensed contractor Ricardo Ortega, has spent over a decade earning the trust of Pasadena and Altadena homeowners. The company holds a 4.9-star average across 30 verified customer reviews, a rare achievement in the trades that reflects consistent execution rather than occasional excellence. Serving the broader San Gabriel Valley, the firm handles everything from routine AC maintenance to complete furnace replacements, positioning itself as a full-spectrum residential HVAC partner for a region where summer temperatures routinely exceed 90 degrees and winter nights can dip into the 30s.

What distinguishes Multi Air from neighboring contractors is Ricardo's unconventional background. Before launching his own firm, he spent nine years designing beer systems and refrigeration equipment for commercial clients, work requiring precision airflow engineering that most residential HVAC technicians never encounter. This experience translates into diagnostic rigor. The company also offers home energy audits, helping Pasadena homeowners identify thermal leaks and ductwork failures that drive up utility bills without obvious symptoms. For property managers seeking documented efficiency improvements, this audit-based approach provides actionable data rather than vague recommendations.

Daniel Spooner's review captures the company's diagnostic philosophy. When called for a routine checkup, Ricardo identified multiple shortcuts previous installers had taken, incorrect refrigerant charges, undersized duct runs, and poorly located vents that compromised airflow across multiple zones. Rather than simply performing the requested tune-up, he presented a ranked list of interventions, explaining which issues required immediate attention versus those that could wait. He provided a line-item estimate allowing the homeowner to prioritize repairs over time. Raina Bonthoux notes Ricardo's same-day response capability, a practical advantage during Pasadena heat waves when AC failures create genuine emergencies.
