Titan Air Conditioning

Titan Air Conditioning has earned a 4.9-star average across 447 reviews while operating 24 hours a day, seven days a week from its Brea headquarters. Owned by Mark Fisher, this family-run contractor serves Diamond Bar, Fullerton, La Habra, Yorba Linda, and surrounding Orange County communities. Licensed and established locally, the company handles everything from routine residential maintenance to commercial buildouts, bringing a neighborhood presence that national chains cannot replicate.

What separates Titan is owner Mark Fisher's hands-on involvement in every job. Multiple reviewers note that Fisher personally visits properties rather than delegating entirely to crews, a practice that lets him explain system mechanics directly to homeowners. The company emphasizes educating customers on how their equipment actually functions rather than steering them toward expensive replacements. This consultative approach consistently earns praise in reviews as refreshingly honest compared to competitors who push unnecessary upgrades.

Doug called Titan after a wall-mounted mini-split in his ADU began leaking condensation down interior walls. Technicians Brandon and Matthew arrived on schedule, presented several repair options, and resolved the issue in under an hour. Doug was so satisfied he enrolled his primary residence in the annual service plan that same day. When another reviewer's furnace failed, Mathew and Freddy visited the following morning, diagnosed the problem quickly, and completed the repair at a charge one reviewer described as very reasonable. Both scenarios illustrate the rapid response and transparent pricing that repeatedly surface across Titan's customer feedback.
