1. Blowing hot instead of cold air
Dirty air filters often restrict proper air movement through the air conditioner, which causes strain and results in hot or warm air to be blown out instead.
2. Unusual noise
In most cases, this may be due to loose parts or an unbalanced fan with dust buildup.
It may also signify that the condenser coil requires cleaning.
3. External vents covered in mould
Often a sign of internal mould buildup. It results in the release of harmful spores and could cause undesirable effects ranging from itchy eyes to long-term lung damage.
4. Filter covered in dust and dirt buil-up
Common sign that your air conditioner requires cleaning!
5. Bad Odour
Over time, the drain pan of your air conditioner may get clogged up from all the moisture removed from your environment, resulting in mould and mildew growth.
