Can I rely on the placement discussed during the sales visit?

Recent reviews show installation teams have later claimed agreed placements cannot be done due to trunking size, despite no detailed measurements taken at the initial walkthrough.

What happens if I find a problem after installation?

Customers report difficulty reaching the sales agent and being directed between staff. One technician demanded photos instead of attending an on-site assessment for a post-installation odour issue.

Are there hidden costs after I sign up?

Yes. One customer was charged an extra $300 (later $200) for pipe overages after installation was quoted, with unclear justification and no prior measurement offered.

What recent reviews say

Most reviewers praise technicians like Sky, Ah Boon, Jackson, Kwang, and sales staff for patient guidance, clean workmanship, and timely service. However, recurring complaints show gaps: installation teams ignore agreed placements, after-sales support is hard to reach, and customers face surprise charges without clear justification. Recent 5-star reviews focus on installation quality, while older 1-star complaints centre on communication breakdowns and poor follow-up on defects.

Recent shift: Recent 5-star reviews (last 10 months) consistently praise installation quality and sales patience. Older 1-star reviews (1–2 years) cite after-sales and billing issues. No clear resolution of the underlying communication gaps between sales commitments and installation realities.

All 15 reviews award five stars. Customers consistently praise named technicians (Bala, Mazedul, Khin, Aru, Vana, Thana) for finishing jobs in under 15 minutes, arriving early, and explaining work clearly. The business asks for photos and assesses jobs before quoting. One reviewer noted competitive pricing; another accepted higher cost for professionalism. No complaints appear in the sample.

Aircon Astiquer Pte Ltd

5.0(2)

Kevin runs a hands-on diagnostic service grounded in 20+ years of troubleshooting skill. Two five-star reviews credit him with spotting hidden problems (clogged water pump misdiagnosed as compressor failure) and saving customers from unnecessary equipment replacement through unconventional methods and honest phone support.
