The MEP Jobs / Contracting Business Salary Survey Tool is now up. You can check it out by going to www.mepjobs.com and clicking on the Salary Survey button. Search by job title and state to find out what folks are making.
A note: this is based on about 2000 responses - thus, not every job in every state is represented. But for the most popular jobs (ie, HVAC service techs), you should see some useful information.
