Revision 11T-724 Available!

This latest application revision includes a "fix" to compensate for a Microsoft security update regarding emailing of Sales Leads and Service Tickets.  It also colorizes the list of Jobsites in the Customer form to indicate Maintenance Contract status.  Also includes fixes for unreported bugs that no one has experienced or reported.   And includes embedded Revision checking to make sure your Quantrac application is up to date on each workstation.

Revisions are free to all Quantrac clients with a current Annual Technical Support and Revision subscription.  Go to Quantrac's Help:About to check your revision.    

A "Revision" is an application improvement that does not require a change to your live database structure.  We work hard to keep Quantrac operational in constantly-updated  Windows operating system environments and publish new Revisions several times a year.

Quantrac Corporation has been providing HVAC software since 1992! The software was developed in a very successful, award-winning company, Airco Comfort Systems, Inc. by a team of software professionals.  There is no more intuitive and easy-to-use package available. 

Here we are, 24years later and under the same ownership. Many of our current customers first computerized their offices in 1992 with our first release. We’ll be happy to share some of the names of our first users as well as those that are more recent. Our software is still very highly acclaimed by its users. We believe that HVAC Office is the easiest to implement and most user-friendly of all.

The HVAC industry is our only focus. HVAC Office is our only product. We are dedicated to serving this industry and don’t share our time with other products and other industries. HVAC Office has progressed through eleven releases since conception in 1992; all geared towards making the management of your company more efficient and profitable.
