License and Subscriptions

HeatCAD licensing is a combination of a perpetual license with a subscription-based support and updates. With your initial license purchase, you automatically receive a 12-month subscription included at no additional charge. If the 12-month subscription expires and is not renewed you can continue to use your current version of HeatCAD indefinitely, but future program updates and technical support will no longer be available to you. When the expiry of this 12-month subscription is approaching, you will be prompted to renew the subscription in order to maintain uninterrupted software updates and support. .

See the Frequently Asked Questions page for more answers to licensing and subscription questions. Refer to the Purchase page for up-to-date pricing information for license purchases and subscription renewals.
