Depending on the age of your home, your contractor may be correct to test for asbestos in your ceiling. The following excerpt from Fiberquant Analytical Services in Phoenix, Arizona at http://www.fiberq.com/ points out this potential hazard:

"Ceiling acoustical sprays consist of a bumpy material, such as mica or plastic foam and a white mineral powder binder. Chrysotile asbestos was sometimes added to the binder. These materials are used to cover up construction defects and irregularities in ceilings (sometimes walls) and to soften the acoustical properties of an area. These types of material could contain asbestos until 1973, when sprayed asbestos-containing materials were banned in new construction."

In light of this, you should have your ceiling tested if your home was built prior to 1973. In either case, the procedure is to "scrape" the ceiling, recoat with a thin layer of sheetrock mud, then sand to a smooth finish. This is a messy process, but is frequently done for aesthetic reasons. If the surface contains asbestos, special procedures must be followed for removal and disposal of hazardous materials.
