UPDATE: Cooling Tower Maintenance Checklist for NYC

cooling tower maintenance requirements and best practices for NYC

Since the Legionnaires’ disease outbreak in New York City a few years back, there has been a great deal of concern and confusion about what’s required for proper cooling tower maintenance.

With many NYC buildings preparing to reopen after being unoccupied for months due to the COVID-19 outbreak, there is concern about making sure cooling towers are restarted safely and properly maintained prior to building occupation.

According to CDC guidance, “The temporary shutdown or reduced operation of a building and reductions in normal water use can create hazards for returning occupants. Two potential microbial hazards that should be considered prior to reopening after a period of building inactivity are mold and Legionella (the cause of Legionnaire’s Disease).”

As a building owner, you want to keep your building occupants safe from dangerous mold and bacteria as well as coronavirus. If you’re in New York City, you must make sure you stay in compliance with NYC’s recent updates to regulations.

New York City has recently released “COVID-19 Interim Guidance on NYC Cooling Tower Regulations,” which contains startup procedures and requirements for cleaning tower maintenance prior to reopening buildings.  An alternative cleaning process is provided for cleaning towers that have been fully cleaned and disinfected within the past 6 months. Otherwise, the general startup process must be completed no later than 15 days prior to first use.

Here’s an updated cooling tower maintenance checklist aligned with the current regulations.

Mold in Air Ducts? How It Got There & How To Get Rid of It

Noticing signs of mold in your air ducts?

ODORS. An unusual or musty odor is often the first sign of mold in air ducts or in air vents. In many cases, you’ll smell it before you can see it. If you notice a musty or moldy smell that goes away when you are not using your air conditioning or heating (if they share ducts), that can narrow the cause down to mold in your HVAC system.

Is Too Much Humidity Hurting Your Health?

You may have read recent research that suggests raising indoor humidity levels may help to deactivate coronavirus particles. During the winter months when our spaces are closed up and heated, humidity levels can drop to extremely low levels (as low as 20 percent). Unfortunately, the COVID-19 virus has been shown to thrive and remain viable for longer periods in these low-humidity conditions.

However, too much indoor humidity can also cause health problems. For example, viruses are known to spread more easily in humidity levels higher than 60 percent. So what is considered high humidity and what are safe indoor humidity levels?

And most importantly, how do indoor humidity levels affect your body and your health?
