Carmel Software, a leader in the development of mobile and web-based HVAC software, acquired Hands Down Software (HDS), a leader in the development of psychrometric chart desktop software. 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.

Hands Down Software and Carmel are both now located in the San Francisco Bay Area. Our clients include customers throughout the world, from the Fortune 500 and the U.S. Government, to smaller architectural/engineering firms.
