Reviewers split sharply: courses and careful service jobs earn strong praise, but routine servicing often falls short of standard practice. Recent complaints cite rushed work, inflated charges beyond advertised rates, and tactics that prioritise payment over diagnosis. Low-cost promos attract customers who report minimal work done.

5.0(490)✓ Google-verifiedPublishes prices

Technicians earn strong praise for knowing their work and explaining what they do rather than just completing jobs. Multiple reviewers name specific staff-Kelson, Shun, Dean, Mr. Din, Mr. Lee-as professional and fast. One unhappy customer reported door damage, disputed upselling, and costs that spiralled to over 600 yuan after a cleaning visit went wrong. The business holds a 5.0 average across 490 reviews, with just 1% one or two-star ratings. Pricing is published by unit count and service type-single-unit chemical wash starts at $90.95, yearly tri-yearly contracts from $160.50 for two units. Service spans all of Singapore from their Kampong Ubi base, and they handle installation, overhauls, gas top-ups, and electrical work alongside routine servicing.
