Three new Windows®-based estimating programs are targeted for the small- and medium-sized mechanical or sheet metal contractor. Pro-Est HVAC is the complete program, available in different versions to suit different contractor needs. Pipe-Pro is a separate pipe estimating program for those interested only in piping. DuctLite is software for those who have their own procedure for estimating material and labor cost, and only want a simple program to calculate material quantities. Developed by a mechanical contractor, the programs are designed to be easy to use, says the company. Professional Estimating Systems, 8430 Fawndale, Houston, TX 77040; 888-477-7462; (website).
