A window air conditioner doesn’t just cool the air — it can also become a source of contamination if not properly maintained.
Inside every window AC unit, there is:
- moisture
- dust
- warmth
👉 the perfect environment for mold growth.
Why Mold Forms in AC UnitsThe main reason is poor drainage and moisture buildup.
This issue became widely known with Midea units, but in reality, it affects all window air conditioners.
If:
- water does not drain properly
- the unit is not tilted correctly
- the system is not cleaned
👉 mold growth is very likely.
Health Risks of Mold Exposure
Mold releases spores and toxins into the air you breathe.
Possible effects:
- coughing and throat irritation
- allergies
- asthma flare-ups
- headaches
- fatigue
- eye and skin irritation
Why You Should Service Your AC Every Season
After months of inactivity, your AC:
- accumulates moisture
- collects dust
- may develop bacteria and mold
👉 Turning it on without cleaning means circulating contaminated air indoors.
Do You Need to Replace the Drain Plug Every Year?
👉 Not always — but it must be checked.
Replace or install if:
- water is not draining
- bad smell appears
- you hear bubbling
- moisture builds up inside
