Singapore's hot and humid climate makes air conditioning a necessity. However, prolonged and improper use of air conditioning can contribute to mould growth.


1. The Link Between Air Conditioning and Mould Growth

a. Condensation in Aircon Trunking – The Primary Cause

60% of mould issues in Singaporean homes originate from condensation in aircon trunking.

b. Poor Air Circulation

Stagnant humidity in sealed rooms promotes mould growth on walls, ceilings, and behind furniture.

c. Dirty Air Filters

Clogged filters spread mould spores throughout the home.


3. How to Prevent Mould Growth from Air Conditioning

  • Use high-quality insulation around aircon pipes
  • Set air conditioner between 23°C and 25°C
  • Clean air filters every two weeks
  • Schedule professional servicing every six months
  • Install mould-resistant coatings on ceilings and walls

4. When to Seek Professional Mould Remediation
