LK Brothers Engineering Pte Ltd -Aircon Servicing Singapore

4.9(1470)✓ Google-verifiedPublishes prices

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 Air-conditioning Pte Ltd

4.8(183)✓ Google-verified

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.

Chan Brothers Aircon

4.8(713)✓ Google-verified

Chan Brothers delivers strong service when technicians like Kun, John, and Elvin handle the job, arriving on time and diagnosing issues thoroughly. Work quality is usually good, staff are warm and communicative, and customers get appointment reminders. However, a long-term customer downgraded from five stars after re-piping with untidy workmanship, leaks within an hour, and pushy upselling damaged their trust after five years of quarterly visits. The gap between technician skill and installation quality raises concern. Most reviews praise servicing; fewer speak to larger jobs. When installations go wrong, they go badly (poor protection of furniture, high mess, moisture issues, system leaks). Staff turnover or inconsistency may explain the sharp contrast between devoted fans and one high-profile burnout.
