Elite Software recently released Rhvac 10, which is a program for ACCA Manual J, D, and S HVAC calculations. The new features in Rhvac 10 can be seen here. The cost of upgrading from Rhvac 9 to Rhvac 10 depends on how long you have owned Rhvac 9. See the upgrade prices here.

One of the new features of Rhvac 10 is the support of the new equipment SEER2, EER2, and HSPF2 ratings. All of the performance values for every AHRI certified model can be found here.

The only problem with the AHRI data is that it is "nominal" data, which means that it is only valid at AHRI test conditions, which include a 95 F outdoor temperature and an 80 F indoor temperature. Many inspectors want to see air conditioner and heat capacities adjusted for your indoor temperature, typically 75 F, and for your local outdoor temperature.

The AHRI web site cannot provide adjusted model capacities for variable conditions. However, many HVAC manufacturers now provide web applications that can calculate adjusted capacities for air conditioners and heat pumps under variable conditions. See a list of those web sites here.

Rhvac 10 now provides a way for you to create equipment database files for all the manufacturers that you sell for, with the models you sell most often. These files are not hard to create, and they can contain your best selling models, with the adjusted capacity ratings already entered for your local conditions. Typically, you would enter 10-15 models for each manufacturer you sell for. Once done, you would then have a one click selection process within Rhvac 10 whenever you need to select equipment for a Manual S report, for example.
