Ying Yau shows wide splits in customer experience. Some praise fast work and solid installations, particularly with Daikin units. Others report aggressive pricing, refusal to honor warranties, and staff who brush off problems once paid. The business appears indifferent to poor reviews, making consistency a real gamble.
Based on limited recent reviews, so treat this as low-confidence.
Perfect five-star rating across two reviews, though review detail is limited. The business claims over ten years' experience in installation, repair, and servicing for Klang area customers.
Review evidence is limited for this business. Their website claims to offer aircon installation, repair, chemical cleaning, and maintenance across Klang and surrounding suburbs, but no customer review text is available to verify experience or quality.
Both reviewers praised fast callout and competent work. One solved a 3hp commercial unit that others had failed on; the other noted neat installation alongside electrical wiring, both at fair rates. Evidence is limited to two five-star reviews.
