Heating and Cooling Apprenticeship

A union is only as strong as its members. That is why organizing is at the center of everything the Internal Association of Heat and Frost Insulators and Allied Workers Local # 53 does. Organizing is the top priority for Local # 53. It is the responsibility of the organizing department to ensure that all mechanic and insulator workers gain the protection of union affiliation. Our daily aim is to increase our membership and restore our union density throughout the trade and industry as a whole. Members of this union apply insulation to pipes, tanks, boilers, ducts, refrigeration equipment, and other surfaces requiring thermal control of temperatures. The responsibilities of these mechanics, improvers, and apprentices also include the manufacture, fabrication, assembling, and all other facets of heat or frost insulation. Workers also handle insulation materials made of fiberglass and the removal of asbestos-containing material.
