HVAC-Calc is built for ease of use. The opening screen lists all the jobs you have done, unless they have been deleted or moved to 'Cold Storage'. As the list gets longer, rather than delete old jobs, you can just move them to Cold Storage and then if you ever need them again, you can bring them back again.

You can also sort the list of jobs by clicking on 'Name', 'Street' or 'Last Modified'. This will become useful when you have a longer list of jobs. 'New Job' will always be at the top and is the selection you make if you want to start a new load calculation.

HVAC-Calc also makes it very easy to start a job on your laptop and then move it, using a floppy disk, to your desktop computer.
