Apr 1, 2020Hvac System Cleaning

In the midst of this time of crisis and uncertainty, we wish to keep you abreast of the goings on here at Power Vac America, where we are, and what we’re capable of doing.

In a letter dated 3/21/2020, NADCA president, Mark Zarzeczny, along with three other industry leaders, implored federal and state and local officials to recognize HVAC and duct cleaning as essential work to be performed during this time of crisis. In the letter, they confirm: “[NADCA] members routinely provide service to maintain continuity of operations of the federal critical infrastructure sectors, as outlined through CISA.

“[NADCA] members perform source removal of contaminants from ductwork and clean and apply antimicrobial to HVAC systems and components where appropriate. [NADCA] members’ services are needed now more than ever as we work together with our facility partners to ensure a safe indoor environment for those businesses who are responsible for keeping our country and our citizens operational during these challenging times.”

In a separate letter, also intended for local and state government, the NADCA president offered the following excerpts from the ASHRAE Position Document on Airborne Infectious Diseases, with key sections noted in bold for consideration:

There are various methods of infectious disease transmission, including contact (both direct and indirect), transmission by large droplets, and inhalation of airborne particles containing infectious microorganisms. The practice of the HVAC professional in reducing disease transmission is focused primarily on those diseases transmitted by airborne particles.


…when outbreaks occur in the workplace, transmission through HVAC systems must be considered.


…transmission occurs not only through direct contact or large droplets, as is the long-standing public health tradition, but also through the airborne route, as newer data suggest,


HVAC systems may contribute far more both to transmission of disease and, potentially, to reduction of transmission risk


Ventilation represents a primary infectious disease control strategy through dilution of room air around a source and removal of infectious agents (CDC 2005).

Based on these statements and supporting information, Power Vac America, Inc. will fall under the Cybersecurity & Infrastructure Security Agency (CISA) guidelines for support of the Essential Critical Infrastructure Workforce. Per CISA, these qualifications include work to be done in the following sectors:

* Public Works – to include: workers such as plumbers, electricians, exterminators, and other service providers who provide services that are necessary to maintaining the safety, sanitation, and essential operation of residences. 

* Other Community-Based Government Operations and Essential Functions – to include: workers to ensure continuity of building functions.

* Chemical – to include: workers supporting the operation and maintenance of facilities (particularly those with high risk chemicals and/or sites that cannot be shut down) whose work cannot be done remotely and requires the presence of highly trained personnel to ensure safe operations, including plant contract workers who provide inspections.

All CISA guidelines are excerpted from CISA’s official Guidance on Essential Critical Infrastructure Workforce, which can be found here.

Please know that we are committed to providing the highest standard of care for our clients and our employees during this time. We are taking all precautions necessary to mitigate the spread of disease, which includes: having non-essential employees safely working from home; all employees out in the field are submitting daily health screen information, such as symptom inventory and fever count; and upon any sign of illness or possible contamination, we fully support an at-home quarantine for those employees until the symptoms are fully resolved.
