Contaminated AC Makes You Vulnerable From Many Ailments

A dirty air-conditioning unit becomes an ideal breeding ground for nasty mold, mildew, and fungi. These types of particles accumulate and hide deep inside the air-conditioning system.

Once inhaled, it can become a factor for many types of illnesses, such as Legionnaires’ disease, breathing problems, and other pulmonary-related diseases. 

Sick Building Syndrome  

This term might sound like an ominous phenomenon, but in reality, it does exist.  The term “sick building syndrome” was first used by Dr. Mark Mendell.

He is an epidemiologist who conducted a research study in the  U.S. Department of Energy’s Lawrence Berkeley National Laboratory.

This occurrence happened around in the ’70s and 80’s, where workers admitted that the building they’re working in seemed to be making them sick. According to Dr. Mendell’s research study, sick building syndrome is highly associated with dirty air-conditioning units contaminating the building’s air.

It caused many ailments, such as nasal congestion, headaches, fatigue, and even dry and irritated skin. 

AC Can Help Ease the Discomfort Caused by Constant Weather Changes

Although a poorly maintained AC poses health risks, a  well-maintained unit can save lives. According to Dr. Michelle Bell from Yale University, an AC could help alleviate the discomfort and dangers brought by intense heat waves.

Importance of AC maintenance
