What recent reviews say

Most installations earn consistent praise for neat trunking, skilled execution, and patient communication. Named technicians like Sanny, Edmund, and Ah Wen are recognized for detail and adaptability on complex jobs. However, two serious complaints reveal cracks: a customer left without aircon for four days after a new system failed, met with "fully booked" dismissal; another paid for servicing only to have the blower vacuumed rather than properly removed. While customer service later made amends on the servicing complaint, the gap between installation excellence and emergency response has shaken loyal customers.

Staff like Sanny stand out for technical knowledge and two-year project patience. Servicing feedback splits between those praising honesty and cleanliness, and those citing skipped steps. Installation typically runs on time, coordinated well, and includes thoughtful details-running pipes neatly, patching gaps, scheduling second trips carefully. Yet the business appears stretched when systems fail within weeks of handover.

Mix of honest, timely servicing and one case where technician skipped blower removal, later acknowledged as fault.

LK Brothers Engineering Pte Ltd -Aircon Servicing Singapore

4.9(1457)✓ Google-verifiedPublishes prices

Most reviewers report consistent, reliable servicing over many years. Technicians like Leong and Wilson are noted as professional, explain problems clearly without pushiness, and work efficiently. One recent complaint raised concerns about unmentioned problems appearing only at a final inspection, though this stands against hundreds of positive multi-year relationships. Their website lists promotional rates and covers most of Singapore. Gas top-ups, chemical cleaning, and yearly contracts feature prominently in positive feedback. The business maintains strong retention across West, Central, North, and East zones.

Most customers praise Chan Brothers' technicians by name for speed, professionalism, and candid explanations of problems. Elvin, Mr Teng, Mr Koh, and others earn consistent mention. One long-term customer, however, reports years of aggressive upselling and repeated unnecessary gas top-up recommendations, including on a brand-new system only six months after installation-a pattern that destroyed their confidence. The tension is real: five-star reviews celebrate fair quotes and thorough work, but the dissenting voice flags a systematic pressure to add charges. Prospective customers should ask for written quotes upfront and seek a second opinion before authorizing refrigerant top-ups or chemical cleaning, especially early in a system's life.
