Why does the Window Air Conditioner Smell Musty?
Musty smells cause bacterial growth increase, which set up on the duct, evaporator coil, or
in the leak pan or drain line of your air conditioner. The window air conditioner smell
musty when the evaporator coil is in an airless and dark position, so all types of must and
mold can rise, which causes that irritating, musty smell. There are some steps you need to
take to find the source of the musty AC smell and how to fix it, including:
Check if your AC drain hollow is full
Check for numb evaporator coils
See if there is too much moisture in your vents or ducts
Recognize if there is a blockage in your condensate line
Dictate if your AC unit is not the right size for your home
Five Reasons Why Your AC Smells Musty
As you wait for your window air conditioner trainer to come, it is helpful to analyze the
problem to guide them to where the potential problem is present. It will speed up the
activity and make sure your HVAC unit is repaired the first time accurately and your
home smells fresh once again.
Here are five common reasons your AC has a musty smell and where you can see to decide
if that is the issue.
1: The Drain Pan is Full:
Because your AC unit erases steamy air from your home, it causes water droplets to fall
into the drain and drip pan. This part of your HVAC system goes through simple wear and
tear. Which means its functionality will decline over time.
Now, an ineffective drip pan can gather mold. The drain causes the smell in your home
when the unit is working. Your local HVAC trainee can change it with a new one to erase
Where to Look:
The drip pan is present directly below your system’s evaporator coils.
2: Frozen Evaporator Coils:
Your window air conditioner emits warm indoor air; erase the moisture while cooling it.
And it also cycles the air back directly and goes back to vents. Unobstructed airflow is
necessary for this process, so air filters must be clean. Debris
