Not enough recent reviews yet to synthesise a reliable sentiment read for this business.
Based on limited recent reviews, so treat this as low-confidence.
A single review from seven years ago alleges the business misdiagnosed a leaking grille, applied a coating that failed to resolve the issue, then refused a refund citing the non-refundable nature of the treatment. The account raises concerns about both technical competence and aftercare fairness.
Single five-star review reflects a customer satisfied with work delivered, though limited feedback prevents full picture. Specializes in anti-condensation and mold removal for commercial spaces.
Most reviewers praise CosyCool for honest technicians who refuse unnecessary work and explain aircon conditions clearly. Multiple named staff (Aung, Lucas, Jay, Sky) earn specific mention for professionalism and patience. However, several long-standing customers report recent frustration with unexplained price increases, communication delays, and charges that appeared without prior notice. One extended complaint details a botched service that required multiple visits and left the customer unhappy despite eventual resolution. Detail is limited by review age; most praise comes from 2-3 years ago, while recent complaints centre on customer service and billing clarity.
