Company Profile
Hands Down Software (HDS), a leader in the development of psychrometric chart desktop software, was acquired by Carmel Software,
a leader in the development of mobile and web-based HVAC software,
in the Spring of 2024. Our plans are to continue to support the 20,000+ users of HDS software (including HDPsyChart) and work on updating the software.
We have also acquired additional HDS software tools listed here, including AcousticCalc, CleanCalc, QwickLoad, and many others.
We plan on streamlining the purchase and registration process so that users can immediately register their software to minimize any downtime due to the software expiring. We will be providing details on all these major changes later in 2024. If you have any questions about this acquisition or our software, please contact us here.
