This download file below contains the HVAC Designer software. It also includes the CAE-Link Noting and Drawing Manager and Drawing Tabs.

If you currently have a copy of HVAC for ACAD 2000-2007, these files will provide an update to your current version which will be compatible with ACAD 2005-2008. If you have a subscription for HVAC, this update will be at no cost. Please NOTE, if you do not have a subscription, you will be required to purchase one to install and use this update. Your old license code will not work and a new license code will be required for installation. Prior to installing the update:

1. If you have a subscription, go to the License page to apply for your new license code. When applying, be sure to select "Update Existing Subscription License" within the License Type option. Be sure to provide all information requested in the form to insure a quick response.
2. If you DO NOT have a subscription, go to the Purchase page to purchase your subscription. Please be sure to provide all information requested to insure a quick response.

If you are a first time user, CAE-Link Corporation will provide you with a 30-day evaluation license at no cost or obligation to you. Simply go to the License page to apply for your evaluation license code.

Installation Instructions

1. If you have previously installed HVAC, to insure a clean installation, start ACAD and unload HVAC, Noting, Layers and any other CAE-Link systems.
2. If you are a new or existing user, insure ACAD is closed. ACAD must be shut down for the installation.
3. Once you have your new license code, download the HVAC Designer. To install directly from the web, select Open. If you prefer, select Save and place the file in a temporary directory. 
4. If you saved the file, go the the file location and double click on the file. The EXE is a standard installation program which is very quick and compact.
5. During the installation, the first requirement is to provide the license code. We recommend you copy the code from your email and paste it into the request. Once the code is accepted, continue and respond to the installation wizard questions. If no code is entered, installation will be discontinued.
6. Next, start AutoCAD and select "Tools/Load Application..." from the menu. For ease of future loading, be sure to check "Add to History" and select the History List tab. Now, find and double click on the file "c:\program files\caelink\load_hvac.lsp" and select Close.
7. The system will load and the HVAC Designer will be available for use.

If you encounter any problems with installation or using the system please email your problem or concerns to support@caelink.com
