Business data from Google Business Profile, checked 2026-09-15.
Recent five-star reviews highlight responsive technicians, clean installations, and fair pricing. However, older reviews document a pattern of missed appointments, staff rudeness, and service inconsistencies. Response times and communication remain common concerns, though the business appears responsive on recent jobs.
Based on limited recent reviews, so treat this as low-confidence.
Coolmax builds strong repeat business through on-time visits, clear explanations, and technicians who work efficiently without pressure to oversell. One customer reports a troubling experience where different technician teams gave conflicting diagnoses, leading them to seek second opinions elsewhere; most others credit years of reliable service and fair pricing with keeping them loyal.
Hassan, Siva, Kelin, Yew, Ah Xian, and Lee consistently turn jobs around quickly. Reviewers praise chemical cleaning results, friendly communication, and pricing they consider fair. But three 1-star reviews raise concerns: one claims the team damaged a condenser during routine maintenance without taking responsibility; another calls pricing excessive; a third alleges pushy practices on coolant refills. These outliers sit against 93% five-star ratings, yet warrant attention if you have warranty concerns or prefer a clearly documented service protocol. Their website lists repair, maintenance, chemical cleaning, residential, commercial, and installation across Singapore. Staff often send before-and-after clarity, and regular maintenance clients report consistent performance. Most recent reviews highlight prompt turnaround and value.
Staff arrive fast and charge fairly for clean, careful work. Hassan and his team communicate well and show up on time for most jobs, from aircon servicing to cabinet carpentry. One customer hit a surprise bill and cited poor communication, but this is rare in the 147-review sample.
