Best for
Customers needing complex fault diagnosis on existing units, not new installations.

Business data from Google Business Profile, checked 2026-11-15.

What do recent reviews say?

Strong spots and serious gaps mix here. A long-term customer praised their ability to fix old units and diagnose complex wiring faults, while another reported Ah Wei quickly found and corrected a cross-wiring installation error. Yet installation defects dominate complaints: one household endured repeated water flooding for months after a new install with no fix; another paid over $500 for outdoor cleaning and refrigerant top-up without proper pressure measurement, leaving units still inadequately cold; a third saw an undiagnosed gas leak cost over $100 with no real resolution.

Based on limited recent reviews, so treat this as low-confidence.

  • Expert troubleshooting on complex wiring and installation issues
  • Long-standing customer relationships
  • Friendly staff attitude
Watch-outs
  • Water leaks after installation not resolved despite multiple visits
  • Refrigerant work done without proper pressure gauges or measurement
  • Poor communication and unresponsiveness after problem arises
  • Installation errors go undetected at handover

Reviews split sharply. Many customers praise the sales staff for patient explanations and the install crews for neat, professional work. Several others describe poor installs, gas leaks, and weeks of unanswered calls after the sale. Praise centres on named staff like Rajan, Crystal, and Hester, and on the Jurong East and IMM showroom team. Complaints cover wrong unit placement, faulty fittings, and a few reports of repeat servicing calls customers did not want. Read recent install reviews carefully before booking.
