4.9(1292)✓ Google-verified

Tommy, Brian, Jun and other Amyth technicians earn repeated five-star praise for arriving on time, explaining work clearly, and leaving spaces tidy. Customers value their honesty; one long-term client notes Tommy refuses to upsell and gives genuine advice after years of trust-building. The company publishes prices openly and confirms charges before starting. One reviewer flagged an expensive pipe replacement quoted that didn't solve their condensation issue; a simpler trunking hole fix worked instead. This suggests scope creep can occur, though it remains uncommon in the dataset.

Reviewers split sharply: five-star customers praise quick turnarounds, Mr Sim's team professionalism, and chemical cleaning results; others report shallow servicing (filter-only in under 20 minutes), inflated charges well above advertised prices, and diagnostics only attempted after payment. The company's aircon courses attract praise for practical depth but complaints of rushed delivery, missing materials, and mismatched course duration versus price tag.

5.0(483)✓ Google-verifiedPublishes prices

Named technicians Kelson, Shun, Din, Dean, and Lee dominate positive reviews for reliability and knowledge. One household reported a damaged bathroom door, contested upselling on gas refill that inflated costs, and staff refusal to take responsibility. Most customers praise these teams for speed, tidy installation, and taking time to explain maintenance and meter readings. Fair pricing and attention to detail stand out across repeated engagements. The single-star complaint, however, flags a serious service dispute that warrants caution.
