Five-star reviews consistently mention fast, neat installations and repeat business over years. Staff handle technical problems well and advise on cost-effective solutions.
Based on limited recent reviews, so treat this as low-confidence.
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.
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.
Not enough recent reviews yet to synthesise a reliable sentiment read for this business.
