Why Does My Air Conditioner Smell Musty? | Kitchener ON

During the hot months from December to February, air conditioners are just like angels descended from heaven, ushering in cool and calm comfort to inhabitants. Thinking of a hot summer day without an air conditioner can be a nightmare for many of us. Over time, these units require proper maintenance and care. If ignored, you might face some health issues along with spending hefty amounts on repairs.

You might smell a musty odour while turning on your air conditioning unit. This smell can be an indication of the growth of mould and mildew. These result in multiple health issues – especially respiratory ones. Let’s dive deep into various reasons for the musty smell coming out of your air conditioning unit and different ways to eradicate it.

1) Filled Drain Pan

The air conditioning unit takes the inner hot air and draws it outside. In return, via vents, it draws the cold in to create a cool, clean temperature inside. The moisture removed from humid indoor air fills the drain pan with constant tipping. An ineffective drain pan becomes a hot spot for mould growth.

To overcome this issue of the drain pan, call a technician to repair or replace it.

2) Clogged Condensate Line

It’s a small PVC pipe functioning for draining water from the drip pan to the storm drain. This is actually located next to the condenser outdoor unit. The condensate line is a culprit for the collection of sludge, mould, and mildew – mainly due to its smaller size. This is one of the most likely reasons for the musty smell in your house.

To carry out the cleaning of the condensate line, remove it from the unit. Make sure to switch off your air conditioner from the thermostat, as well as from the breaker. Put hot white vinegar in it and wait for half an hour. Finally, rinse it with clean water and attach it back to its original spot.

3) High Moisture Levels in Ducts and Vents

When running an air conditioner, usually humidity increases in the room. This accumulates in moisture in air ducts and vents. Drainage leaks can also lead to such situations. The accumulated moisture provides an environment for the growth of disease-causing moulds, which results in a musty smell from your air conditioning unit. This is a technical issue; calling a professional will resolve your issue.

4) Bigger-Sized AC

Air conditioners must be customized according to the requirements and available space. Anything too big or too small will create complications resulting in inefficiency. A bigger unit cools up space too quickly, thus reducing the dehumidifying process. When humidity takes over the environment, it would potentially lead to moist conditions.

That’s why it’s recommended to consult an expert air conditioner technician or dealer to choose your AC unit according to available area requirements.
