AC TECH Auto Repair & Service

AC TECH Auto Repair & Service has kept Pasadena vehicles running reliably since its founding, backed by mechanical engineer Emiliano Bertazzo and a team of ASE-certified technicians. The shop holds a 4.9-star average across 34 verified reviews, reflecting two decades of consistent customer satisfaction. Located at 717 N Lake Ave in central Pasadena, the facility serves drivers throughout the San Gabriel Valley including Altadena, San Marino, and Arcadia neighborhoods. Their Saturday hours until 2pm accommodate commuters who cannot visit during the weekday window.

What distinguishes AC TECH from neighboring repair facilities is their willingness to tackle unusual challenges. Reviewers document work on rare rotary engines, vintage Mercedes V12s, and plug-in hybrid transmissions, vehicles that many area shops decline to service. The shop maintains state-of-the-art diagnostic equipment and performs every repair in-house, from engine rebuilds to transmission replacements, without outsourcing complex work to third-party specialists. Their transparent pricing structure means customers receive itemized estimates before any repair begins, eliminating the surprise charges that erode trust at dealership service departments.

Customer experiences reveal the team's approach to high-stakes repairs. When Tom S's Honda Clarity required a full transmission replacement, technician Emiliano managed the entire process with daily updates and completed the work efficiently enough that the customer regretted not visiting first. Andy Klein describes the shop as the rare mechanic where he 'never has that uneasy feeling of being overcharged or sold services you don't need.' Marlon Lerman specifically notes their capability with both domestic and import makes, emphasizing that foreign or domestic vehicles present no problem for the certified team.
