Legionella is a type of bacterium that causes the respiratory illness called legionellosis.
Legionella dwells in natural water systems, but thrives more in hot and artificial water systems. The Center for Disease Control and Prevention explains that the heated water of cooling towers of air conditioning systems provides an ideal environment for Legionella growth. Accom News adds that the bacteria “is most active when the temperature of the water is between 20° and 45° and there is sufficient nutrient to support growth and multiplication.”

When people breathe in water droplets that contain legionella, they can be infected with legionellosis. In 1976 in Philadelphia, there was an outbreak of the disease when the American Legion convention members got infected due to contaminated cooling towers. Legionnaire’s disease, a form of legionellosis, was coined after this outbreak.
To prevent legionella from thriving in the cooling towers of air conditioning systems, regular inspection and cleaning must be observed. Both cooling tower manufacturers and companies that have cooling towers must follow strict maintenance guidelines. Companies can also seek the services of air conditioning and heating contractors like Comfort Experts and Quality Cooling and Heating, which conduct air quality analysis to make sure that there is no legionella in the air.
