Rhvac version 10 can be installed on the same computer as version 9, and will not interfere with version 9 at all. There is no problem in having both version 9 and version 10 on your computer at the same time. If you already have a license for version 9, see the upgrade pricing schedule.

Version 10 includes the following powerful new features that were not in version 9.
ACCA Form 310 Window
This is a report that documents the quality of an HVAC design and installation. Many jurisdictions now require this Form 310 report. Rhvac 10 can save you many hours on generating the Form 310 report. See more about this report here.
SEER2, EER2, and HSPF2
HVAC equipment inputs in Rhvac 10 now include these three new rating values. Rhvac 10 provides for the entry of these values for any equipment specified in the software. See more on selecting equipment data here.
Negative Overhang Offset
Some windows have awnings that extend down the window from the top. Rhvac 10 allows the overhang offset to be set as a negative value to account for that.
Metal Walls with Spray Foam
Many new homes, such as "barndominiums," use light gauge steel framing with R-panel metal sheathing. Rhvac 10 has new metal wall selections for this situation.
"Show Flow" Trunk Property
Many jurisdictions now want to see the CFM flow rate on every duct in a duct system. Rhvac 10 now provides this option.
