Nancy and the installation team earn trust through upfront site inspections and straightforward advice; Ah Wai and colleagues work efficiently and complete the job to standard. One dispute over gas-refill logic clouds an otherwise consistently positive record, but 95% five-star ratings suggest isolated incident.
Two reviewers praised thorough servicing and honest guidance on unnecessary work; two others reported serious issues: unresolved problems after servicing went unanswered, a loose wire reconnection was blamed on parts failure, and charges exceeded quoted rates. Evidence is limited but sentiment is sharply divided.
Most customers report prompt, professional service and clean work. Technicians like Leong and Harid earn individual praise, and some clients have used LK Brothers for eight years without issue. However, a pattern emerges: several customers were quoted or charged for major work (chemical overhauls, condenser replacement, part replacements) that was either not previously identified, not clearly authorised, or did not resolve the stated problems. One customer reported their unit leaking weeks after routine service, only to be told expensive further work was needed. Another was charged for chemical wash despite not authorising it, and had their calls blocked when requesting clarification. </ the texture is one of reliable day-to-day servicing undermined by pricing surprises and scope creep. Promotions advertise steep discounts (chemical wash $210 for 3 units versus $80/unit usual), but multiple reviews suggest customers end up paying significantly more than quoted after on-site diagnosis.>
U Sin delivers reliable air-con work across servicing, installation, and chemical wash. Reviewers consistently praise punctuality, professional technicians by name (Sanny, Raja, Edmund), and clean workmanship especially on trunking. One complaint: a technician vacuumed rather than removed a blower during a $35 service; the firm offered a refund but response was slow. Strong suits are patience during long projects, transparent pricing with no unnecessary add-ons, and hands-on coordination from office staff. Installations span HDB flats to full-home systems. Most reviewers return for maintenance after installation, signalling trust in both workmanship and ongoing care.
