After a long hot day, all you want to do is to come home to a nice smelling home. What you do not want is to smell a musty odour coming from your air conditioner. The musty smell is due to bacteria growth in the system. Let us tell you what the causes are.
FULL DRAIN PAN
Because your air conditioner eliminates humidity from your home, water droplets fall into the drip or drain pan. Because this component of your air conditioning system is subject to regular wear and tear, its functionality will diminish over time.
When the unit is operating, an inefficient drip pan collects mold, which generates the odor in our house.
FROZEN EVAPORATOR COIL
Your air conditioner takes warm interior air, eliminates humidity while chilling it, and returns it through return vents. Airflow must be unobstructed for this operation, therefore air filters must be clean.
Dirt and debris obstruct airflow, causing water droplets from the humid indoor air to accumulate on the evaporator coils. As the refrigerant in the AC unit cools the air, these water drops will freeze.
EXCESS MOISTURE IN PIPES
Excessive moisture inside pipes is caused by high humidity levels or a drainage leak. If you notice a musty odor as soon as you switch on your air conditioner, mold and mildew may have infiltrated your ducting.
Mold can cause upper respiratory health problems, so contact a professional air conditioning technician as soon as possible. To permanently remove musty odours from your ducts and vents, duct cleaning and repairs will be required.
If you are trying to cover up the smell with aerosol sprays, scented candles, and the like, you are only worsening the air quality. Save yourself from irritated eyes and skin, nausea, headaches, breathing difficulties, trouble sleeping, and many other health problems by scheduling a professional indoor air quality inspection.
BACK TO BASICS
As the foul smell is due to the growth of bacteria, it could affect your health. Regular maintenance could remove that awful smell. As regular maintenance is done every 3 to 4 months, it could remove the bacteria that are growing in the fan coil unit. Feel free to contact us for more information.
