What recent reviews say

Crystal, Prabhu, and service technicians like Mahbub and Abbas earn consistent five-star praise for patience and skilled work. Yet repeated complaints paint a stark picture: gas and water leaks within days of installation, piping done poorly enough that a recheck five years later revealed mismatched insulation and inadequate taping, and installers who ignore customer instructions, demand hidden charges mid-job, and dismiss concerns with hostility. Sales promises do not survive into the field.

Follow-up after problems is spotty or absent. Customers report being ignored for weeks after raising issues, receiving servicing vouchers they bin, and being pestered by sales calls after explicitly refusing them. One reviewer summed the pattern: "Display can be misleading." The company's trophies and promises do not match the experience delivered. A site survey before work begins is not standard practice here.

Praised for
  • patient, knowledgeable sales staff (Prabhu, Crystal)
  • skilled installation teams (named technicians praised for neat, efficient work)
  • responsive support staff in problem resolution (Charles)
  • professional servicing technicians available
Watch-outs
  • gas leaks and water pipe leaks after installation
  • poor installation workmanship (slipshod piping, misaligned insulation)
  • lack of follow-up after poor service or complaints
  • aggressive upselling and harassing sales calls about servicing
  • communication gaps between sales promises and field execution
  • hidden costs and unexpected charges
  • unprofessional, dismissive installer attitudes
  • no site survey or planning before installation
  • staff dismissal of customer concerns during installation

Think twice if: Installation quality is unreliable; gas and water leaks are recurring. No site survey standard. Expect communication gaps between sales and field work, hidden charges, and difficulty reaching management after problems.

Strengths

  • individual sales staff (Prabhu, Crystal) known for patience and product knowledge
  • named installation teams that deliver neat, efficient work when motivated
  • professional servicing technicians on staff

Worth knowing

  • Salesperson Prabhu (IMM) praised for explaining Daikin System 5 features and repeat-customer loyalty
  • Installation team Rajan, Johnny, Naing complimented for efficiency and neatness in one 5-star review
  • Support staff Charles manages problem escalation but follow-up timelines slipped (promised Monday, nothing by Saturday)
  • Technician Mahbub delivers servicing to professional standard
  • Gas leaks and water-pipe leaks documented within first night to one week of installation
  • Five-year-old installation opened for unrelated repair showed 'Frankenstein' piping with mismatched insulation pieces and black tape
  • Charging $80 to reuse customer's existing 16mm piping instead of upgrading; $180 bracket cost discovered mid-installation; $100 'consultation fee' for pre-installation site discussion that was not communicated to field crew
  • Harassing monthly calls for servicing after customer asked to be removed from contact list

What reviews say by service

Highly variable: praised for neat, on-time work by repeat customers; panned for gas leaks, water leaks, poor piping, ignored instructions, hidden charges, and rude dismissals of concerns.
Aircon Servicing & Repair
Professional technicians (Mahbub, Abbas) lauded for standards; but aggressive upselling via monthly harassment calls, generic servicing (vacuum and cloth wipe, $160 with voucher), and poor follow-up on complaints.

Common questions

Are their installation teams experienced?
Mixed. Reviewers name praise for Prabhu, Rajan, Johnny, Naing, and Abbas when work goes well. However, repeated complaints cite poor piping, ignored instructions, and lack of site survey beforehand. One five-year-old installation was found to have 'Frankenstein' piping with mismatched insulation pieces.
What if something goes wrong after installation?
Follow-up is unreliable. Several customers report no response to messages for weeks after raising issues. One customer was promised management follow-up on Monday and heard nothing by Saturday. No formal after-sales support process is evident.
Do they charge hidden costs?
Yes. Reviewers were surprised by $80 to reuse existing piping, $100 consultation fees for site discussions, and a $180 bracket discovered mid-installation. Sales staff do not itemise these upfront.

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.
