Greetings ASHRAE Members,

On Friday, February 18, the temperature in Lancaster reached 73°F, breaking a record set in 1938. While I am writing this President’s message, the temperature is now in the low teens with almost five inches of snow outside. I wish the weather would make up its mind. If you are trying to make up your mind about whether to join ASHRAE or to come to one of our meetings, now is the time to make up your mind and join us!

This month is Membership Promotion night. All new members who sign up this month can attend our March 9 chapter meeting for FREE! This is in addition to all of the other benefits of ASHRAE membership, including the monthly ASHRAE Journal and the yearly ASHRAE Handbooks. Join ASHRAE in “advancing HVAC&R to serve humanity and promote a sustainable world.”

You can sign-up for ASHRAE membership online at If you have any questions about joining, please contact me (Mark Graybill – or our membership promotion chair Nate Potteiger ( Also contact us if you would like to get involved with our local chapter operations.

We had another well-attended meeting this past month with a presentation entitled “The Latest in Dedicated Outdoor Air Systems (DOAS)” presented by ASHRAE Fellow and Distinguished Lecturer Stanley Mumma, Ph.D. I thank Dr. Mumma for speaking to our chapter and for his knowledge and enthusiasm for DOAS.

Please join us on March 9 at the Appalachian Brewing Company for two presentations by separate speakers but both related to balancing. The first is on “Hydronic Balancing in a Variable System” and the second is on “Air and Hydronic Balancing from the Balancer’s Perspective.” I am looking forward to both of these presentations as well as the follow-up discussion and questions from our members.

Mark M. Graybill, PE
