To All of Our Customers:

K & D continues to follow all guidelines as set forth by the state and local officials and will perform service and/or construction work as long as the job site meets these guidelines.

As an essential business, we will continue to provide emergency construction and service repairs as needed. All our employees are doing everything we can to follow best practices in our personal lives and practicing safe distances on the worksite.

We continue to monitor the situation and if new guidelines are issued, we will adjust our practices to adhere to them. All emergency calls should be directed to James Dahlen for consideration.

ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers), through its Environmental Health Committee, created the Epidemic Task Force, and has issued the following statements:

Statement on airborne transmission of SARS-CoV-2

Transmission of SARS-CoV-2 through the air is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including the operation of heating, ventilating, and air-conditioning systems, can reduce airborne exposures.

Statement on operation of heating, ventilating, and air-conditioning systems to reduce SARS-CoV-2 transmission

Ventilation and filtration provided by heating, ventilating, and air-conditioning systems can reduce the airborne concentration of SARS-CoV-2 and thus the risk of transmission through the air. Unconditioned spaces can cause thermal stress to people that may be directly life threatening and that may also lower resistance to infection. In general, disabling of heating, ventilating, and air-conditioning systems is not a recommended measure to reduce the transmission of the virus.

ASHRAE solutions

ASHRAE is actively seeking solutions by using its internal and external resources to develop guidance that can be used now and by supporting research on building design for future mitigation of the transmission of pathogens through the air.

To that end, ASHRAE will recognize the devastating consequences of global pandemic viral or bacterial outbreaks and be proactive in developing engineering guidelines for minimizing the spread of these biological hazards in building systems.

Provide guidance on the use and operation of interventions that promote healthy air quality in spaces and facilities for institutional buildings, residences, healthcare facilities, workplaces, and public transportation.

Conduct training on these interventions that are not always understood in the context of building design, construction, and operations.

Take full advantage of the knowledge among its members to create evidence-based infection control practices during this pandemic and prior to future pandemics.

Provide Society membership and the worldwide community a greater appreciation and understanding of the role played by heating, ventilating and air-conditioning to minimize the risk of infection from airborne transmission within the built environment.

Mechanical Air Filters

Consist of media with porous structures of fibers or stretched membrane material to remove particles from airstreams. Some filters have a static electrical charge applied to the media to increase particle removal. The fraction of particles removed from air passing through a filter is termed “filter efficiency” and is provided by the MERV under standard conditions.

MERV ranges from 1 to 16 (higher MERV = higher efficiency). MERV equal or greater than 13 are efficient at capturing airborne viruses. MERV 14 filters are preferred.

K & D provides Merv-8 as standard Preventative maintenance practice, we can provide Merv-13 for an additional fee of $20.00 per filter without any modification to existing equipment.
