What do customers say?
Most recent reviewers describe smooth jobs from first enquiry to finished install. Site visits came before the work, quotes matched the final bill, and crews tidied up afterward. Rating sits at 4.7 across 178 Google reviews, with 94% of the last 16 at four or five stars.
Installation is the main story here, with Mitsubishi Electric Starmex and Daikin systems, plus condo and BTO jobs. Several reviewers name Raymond as site manager and Najib, Tawhid, and Alam among installers. Servicing with a chemical wash also gets positive notes. One older one-star review disputes a Samsung piping fix and is not repeated in recent reviews.
