AC Odors And How To Combat Them

If you have central air in your home, then you may notice that the cool air coming out of your vents does not seem nearly as fresh as it once did. If the odor is a musty one, then this is a common problem, and thankfully, it does not mean that you need a brand-new HVAC system. When experiencing foul odors, there are a few things you can do to combat it.

Investigate Your Coils

Your AC system deals with a great deal of humid air, especially if you live in Florida or another southern state. Air conditioning systems are capable of removing water from the air with the help of the condenser coils. Water forms on these coils in the form of condensation and the water falls into a drain pain where it is pumped out of your house through a drain line. 

Sometimes your AC system cannot handle the amount of water in the outdoor air that is used for cooling purposes. This is often the case if it is extremely humid for a long period of time or if the condenser coils are dirty. Dirt specifically will absorb the water and keep it from falling into the drain pan. When this happens, mold will often develop on the coils. When air passes over the mold, spores come loose and enter the ductwork. 

Take a look at the coils in your AC system and clean them if you see any signs of dirt. A foam spray is often suggested, and this product does not require the use of a scrub brush to remove debris.

Look At The Drain Line

If mold and mildew have started to develop anywhere inside the HVAC system, then there is a good chance that the mildew and debris have collected to come degree in your drain pan. As the mold and mildew flow to the drain line, it often clogs. Odors may then flow from up and into your ducts. 

You can often tell if the drain line is clogged since water will pool on the floor. If you see this, then empty the drain pan and clean it out with bleach. Look for the drain line and use a pipe cleaner to clear it out as well. Return the drain pan and fill it with vinegar. This will help to get rid of any leftover mold or mildew. 

If you want to know more about odors coming from your AC system and how they can be addressed, speak with an air conditioning maintenance professional.
