Hello Kerry Ann!
I am the C2C monitor this period and thanks for your question! We cannot give recommendations for brands, and to be honest, selecting a specific AC unit is out of my expertise. However, I will reach out to some experts to see if they have some information to share with you.
Are there any reasons or concerns about your current system that would give you pause to just add the same units? And do you have a HVAC specialists or buildings manager at your institution, or do you rely on a vendor for installation and upkeep?
Best,
Beth
