Update on Hahn Mason Air System’s Coronavirus Contingency Plan

We wanted to share an update on our efforts to help keep our operations up and running during the Coronavirus (COVID-19).

HMI is closely monitoring the latest reports from the Centers for Disease Control (CDC) and the World Health Organization (WHO) and the local, state, and federal government and we are taking several precautionary measures for the health and safety of our customers and team members.

Experts suggest that the only way to stop this virus is to limit contamination. To that goal, we are temporarily instituting a remote work policy. We will still maintain a critical function at our warehouse and in our internal business functions.

Our goal is to do everything we can to keep our operations up and running and people safe during this unprecedented and evolving situation.  While we have asked our employees to limit customer contact, we understand they still need to support our customers and have instructed everyone to use their discretion for all meetings, site visits, etc…. Thank you for the opportunity to serve your HVAC needs.
