What are potential health risks of poorly maintained AC systems?

Poorly maintained air conditioning systems can indeed lead to mold growth and an increase in allergens, which represent significant health risks. When an AC system is not regularly cleaned and maintained, moisture can accumulate in the ducts and other components due to condensation. This damp environment can become a breeding ground for mold spores and bacteria, which can then be circulated throughout the indoor air.

People who are sensitive to mold, such as those with asthma or other respiratory conditions, can experience worsening symptoms, leading to serious health issues. Moreover, the presence of allergens and irritants in the system can also aggravate existing allergies and contribute to respiratory problems in otherwise healthy individuals. This highlights the importance of routine maintenance, including replacing filters and cleaning ductwork, to ensure that the air being circulated remains clean and safe for occupants.
