That gloriously cold air rushing out of your vents shouldn’t have a smell to it. In fact, you shouldn’t even realize it is doing its job other than your own comfort. Sometimes, there may be odd sounds and even smells that are coming from the vents that may alarm you. Today, Hal Mechanical is here to discuss what the issue could be if you are smelling something musty every time your AC kicks on.
Why Does My Central AC Smell Musty?
There are several different issues that could be causing your AC to emit a musty smell every time it turns on. Here are some of the top reasons, this problem is happening.
– Frozen Evaporator Coils: Your air conditioning system works to cool your home by not only sending cold air through the vents but removing the humidity and excess moisture as well. The air needs to be able to flow freely around the unit for the process to be successful. If you have dirty air filters, it doesn’t allow this to happen. In fact, there can be droplets of humidity that end up landing on the coils and freezing. To avoid this, you should be replacing your filters regularly.
– A Full Drain Pan: All the moisture that is removed from the air in your home causes droplets to fall into a drain pan. If it isn’t draining as it should, which can happen over time, moisture just builds up there and the water can turn into a place that mold can begin to grow.
– Blocked AC Condensate Line: The portion of your AC unit that is outside is known as the condenser unit. The condensate line is simply a small PVC pipe that allows the moisture to drain the moisture from the drip pan to your landscaping or to the storm drain. This is a small pipe and that makes mold and mildew a problem since it can get clogged rather easily.
– Wrong Size AC Unit: If you have a unit that doesn’t fit your home well, it can create a list of problems. One of them is mold and mildew growth. This comes when the AC unit is too large for your home. When it is too big, it cycles the air through too fast, without removing all the humidity properly. This leave excessive moisture in your unit and potential mold and mildew growth. This is why it is so important that you have professional help when selecting the right sized AC unit for your home.
