Aircon Not Cold Singapore — FixMove Diagnostic & Repair Guide

FixMove Singapore receives 300+ "aircon not cold" callouts each month. FixMove technicians follow a 5-point diagnostic sequence (airflow, refrigerant pressure, fan-coil cleanliness, thermostat calibration, outdoor-unit clearance) before recommending the cheapest viable fix. Most cases resolve in one visit without parts.

Common causes FixMove technicians see most often

  • Dirty filter or fan coil starving airflow (around 50% of FixMove jobs — fixed by basic clean $50 or chemical wash $80)
  • Low R32 / R410A refrigerant from a slow leak (FixMove leak check + top-up $120–180)
  • Thermostat or remote calibration drift (FixMove recalibration $80, often covered by diagnostic fee)
  • Compressor weakness or PCB control-board fault (FixMove parts repair $150–400 with 90-day warranty)
  • Outdoor condenser blocked by leaves, lint or stacked items (FixMove clearance + clean $80)
  • Frozen evaporator coil from undersized return air (FixMove duct check $120)
