Business data from Google Business Profile, checked 2026-11-15.
Only two Google reviews exist, both five-star and both about three years old. They praise a full strip-down clean and fair pricing. Evidence is too thin to judge consistency.
Based on limited recent reviews, so treat this as low-confidence.
Koomax Engineering earns a perfect 5 average from 31 Google reviews in Bishan. Reviewers consistently praise on-time technicians, careful floor and furniture protection, and fair pricing. Some also say the customer service staff replies quickly and keeps them updated.
Precision AutoMech handles car electronics and installations in Bishan with a soft-spoken owner who prioritizes customer service. One reviewer noted a quality-control miss during BlackVue camera setup at the OEM level, but the shop resolved it immediately via warranty exchange; other jobs turn around in under an hour.
Reviewers describe a steady, long-running service. Several customers say they have used SoCool for years, and many praise the technicians for thorough cleaning and clear explanations of what needs fixing. Named technicians come up again and again, including Brendon, James, Michael and Jackson, and Ah Yao. Customers mention chemical overhauls, gas top-ups, and servicing contracts. Prices are often called reasonable, and a few say the team handled LG units well.
