Thank you for everything that you are doing to keep family, friends, loved ones, and our communities safe.  The COVID-19 pandemic has changed the world significantly over the past few weeks. The situation is still very fluid and will continue to evolve.  Together, we will get through this!  Below are a few specific updates as it relates to HMI:

  • Friday, 4/10/20, is a company-wide holiday and we will be closed – this includes the warehouse.
  • The 2020 stock book is complete and available via our website on the products tab:
  • The Hahn Mason PO BOX 31248 has been officially closed. Please have everything sent/forwarded to the street address
    • 4901 Dwight Evans Road, Ste. 120

  • The warehouse will be closed for year-end inventory on Friday, May 1st, 2020.

A key component of HMI’s core values is to ensure the shared success of our employees, customers, business partners, and we remain committed to this goal through the current situation.   Take care of one another.

HMI Update 3-25-20

Hahn-Mason remains open for business.

As many are aware, Mecklenburg County has issued a “Stay at Home” order, effective 8 a.m. Thursday, March 16th through Thursday April 16th.  Due to the nature of our business (we are a “critical trade”) we are keeping the warehouse open and available to the community.  We continue to follow the “social distancing” strategy, so when customers arrive at the warehouse to pick up their order, we ask that they please call us at 704-523-5344.  We will pull your order and bring it to your vehicle or place it on the dock for self-loading.

HMI Corporate functions and the Local Branch Offices are continuing with our work remote policy. Our personnel remain available via email and phone.

The majority of our manufacturers remain open and in steady production.  However, some of our manufacturers that are located in states who have implemented “Stay at Home” orders are starting to broadcast a slowdown or prioritization of orders.  Please contact your HMI representative for specific order information or details on shipments that may be impacted.

Thank you and stay safe.

HMI Update 3-20-20

As you are aware, the number of cases of COVID-19 in North and South Carolina continues to increase daily. The transfer of this virus from person to person (“community spread”) is increasing and we continue to monitor the evolving guidelines coming from local, state and federal officials.


Currently, the Centers for Disease Control and Prevention (CDC) state that people should practice social distancing by remaining at least 6 feet apart to minimize the risk of unintended spread of the virus. Additionally, gatherings of groups of 10 or more people are currently discouraged. To follow these guidelines and do our part to mitigate the impacts of the virus on those most vulnerable in our community, HMI has adopted the following policies we feel will best help our employees stay healthy:

“Social Distancing:” – HMI has adopted this strategy.  All travel and in-person job-site meetings are discouraged. We ask that everyone utilize technology / virtual meetings, as appropriate.

Warehouse: The Warehouse is in operation with a reduced number of employees physically on-premises. We are encouraging the use of courier services for all orders. We are limiting the number of personnel in the building to less than 10 people. Additionally, we are asking that customers call ahead and let us know when they are on site. We will load the material into vehicles or place outside for self-loading. As a reminder, the warehouse is first come, first serve. Currently, our manufacturers are not reporting a shortage of materials or delay in delivery of materials.


Accounting: Corporate Accounting is in operation with a reduced number of employees physically on-premises. We plan to have a full staff available for end of month activities.

Local Branch Offices: We are continuing with our work remote policy. Our personnel remain available via email and phone.


We appreciate your patience as we continue to develop policies that make the most sense during this unconventional time. We realize many of you are facing challenges at work and home, so we hope to continue making our services accessible to our employees and customers as much as possible as we navigate the next few weeks. HMI will monitor conditions on an ongoing basis and adjust our plans if needed.

Please take care of all your activities and use common sense – if you or any family member do not feel well please seek medical attention. Should the situation change in such a way that requires further modifications we will keep everyone informed.

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.
