When your AC kicks on, the last thing you want is the air coming out to have any smell whatsoever. In fact, it shouldn’t have a smell. Sometimes, you may find that there is a musty smell that accompanies that blessed cold air blowing out your vents though. This is indicative of a problem. Absolute P&M Services is here to break down the issues your AC unit could be having that would cause it to have a musty smell.
Frozen Evaporator Coil
Your AC unit successfully cools your home down by following the process of absorbing warm indoor air, removing humidity & cooling it and then blowing out cooled air through the vents. Your filters need to be clean to allow the air to freely move throughout the system. It is actually vital to the success of your AC unit. If there is dirt and debris that is blocking this air from flowing, water can collect on the filter from the humid air. That water then drops on the coils and cause them to freeze up. Changing your filters monthly will help you avoid this issue and the risk of musty smells coming through the vents.
Moisture in Air Ducts & Vents
If you turn on your AC only to find that musty smells are coming from the vents, it’s a good indication that there is moisture somewhere in the ductwork. This can be caused by any leak that is going unnoticed or the high humidity level in the home. Because mold and mildew cause serious upper respiratory issues for those breathing it in, it is important that this problem is checked out by a professional right away.
Full Air Conditioner Drain Pan
As your AC unit works to remove moisture from the air in your home, there are usually water droplets that need to go somewhere. This is why there is a drain pan in your unit that catches all of that moisture. If the drain pan isn’t working as it should and is completely filled with moisture all of the time, it could start to grow mold. You would be able to smell this when your AC is on.
Clogged Condensate Drain Line
The condensate line is a small PVC line that works to remove the water that accumulates in the drain pan. This can easily become blocked because it isn’t very large in size. When working effectively, it should remove the moisture and drain it somewhere into your landscaping so issues don’t arise. Many homeowners don’t realize they should be cleaning this, and by not doing so, it causes issues.
