How Your AC Can Cause Foul Odors
Unusual odors can be emitted from your AC system at any time, but often when you start to use your HVAC system after a period of inactivity. The transition between seasons can also create conditions that result in foul odors. The fluctuation between heating and cooling can promote the growth of mold, mildew, and other biomaterials that can result in an unpleasant smell emanating from the air conditioning system in your Alexandria, Virginia home.
Understanding Your Air Handler’s Environment
One of the main causes of mold and mildew problems is moisture. The environment in the air handler can lead to high levels of moisture as the system operates. The constant conversion of the refrigerant and the process to deliver conditioned air to your home causes moisture in and around the evaporator coils. The moisture collects on the coils and drips into a drain pan for removal from the area. If the pan doesn’t drain properly it can cause water to backup or become stagnant. In addition, the excess moisture can lead to mold growth. Odors from these conditions can affect the air that circulates through the system and into your home.
Dirt and debris from the system and your indoor air can settle in your ductwork. Along with waste and shedding from small animals and insects, these can significantly affect the quality of your indoor air. If these animals die in the ductwork, it can certainly create a foul odor throughout your home. Mold, spores, and other biomaterials can also thrive in the ductwork.
Preventing AC Odors with Maintenance Service
Preventing moldy conditions, dirty air filters, poor drainage, and contamination in your ductwork are extremely important for the health of your household.
Prior to using your air conditioner as the weather warms up, be sure to contact your HVAC professional for a thorough system inspection and tune-up. This includes cleaning your evaporator coils and drainage system. Preventive care also improves efficiency levels and your ability to maintain optimum comfort during the cooling season.
