What recent reviews say

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.

Recent shift: Negative reviews concentrate in the most recent 3–4 years; five-star reviews (mostly aircon courses and positive servicing) cluster around a year ago. Recent one-star complaints centre on servicing depth, overcharging, and diagnostics practices, suggesting either quality slippage or selective customer base changes.

Praised for
  • fast response times
  • friendly and professional technicians
  • chemical cleaning solves cooling issues
  • practical aircon courses
Watch-outs
  • minimal servicing (filter wash only, no fan coil or drain cleaning)
  • overcharging beyond advertised rates
  • shoddy diagnostics and post-payment troubleshooting
  • no accountability for damage
  • courses too short and overpriced
quick-responseprofessional-serviceoverpricedpoor-communicationunresolved-issueskilled-techniciansclean-workmanship
Best for: customers seeking chemical cleaning for leaking or poorly cooling units, or hands-on aircon maintenance training
Think twice if: get a written quote upfront and a second opinion before accepting any major repairs, diagnostics, or gas top-ups; some customers report charges far exceeding published rates

Strengths

  • responsive booking and appointment scheduling
  • Mr Sim and team deliver thorough cleaning on good jobs
  • practical aircon training with hands-on elements

Worth knowing

  • Mr Sim leads technical team and training delivery
  • fast appointment turnarounds
  • advertised servicing under 20 minutes in recent complaint, suggesting minimal depth
  • website lists annual maintenance contracts (wall-mount, 4x servicing per year)
  • courses offered: Basic and Advanced Aircon Servicing
  • several customers report technicians skipping fan coil and drain tray cleaning despite it being industry standard
  • one customer had compressor work misdiagnosed until corrected mid-job
  • charges for R32 gas top-up documented at $200/system vs advertised $50–$150, and chemical wash quoted at $150/indoor unit

Common questions

What does a general aircon servicing include?
According to one recent review, the service included only filter washing in under 20 minutes, with the fan coil and drain tray left uncleaned. This does not appear to meet industry standard. Reviewers who had chemical cleaning done reported better results (full cleaning, fan coil addressed).
Do you offer annual maintenance contracts?
Yes. Their website lists annual wall-mount contracts with four servicing visits, ranging from $170 (1 unit) to $460 (6 units).
What should I ask for before agreeing to gas top-up or repair work?
Get a written quote in advance. Reviewers report actual charges ($200/system for R32 gas) have exceeded advertised rates ($50–$150 range) by 2–4x. Request pressure readings and a detailed diagnosis before payment.

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.

Multiple customers praised Paul's team for patient guidance, timely installation, and protective care during jobs. One long-standing complaint described faulty piping that caused problems within two years and no response from the business. Recent uncertainty clouds the picture: a reviewer reports the Kinex shop location closed without updated information on either website.
