G.W. Berkheimer

G.W. Berkheimer has served the Jolietarea since 1979, operating as a wholesale distributor of HVAC equipment parts and supplies. The business holds an A+ rating with the Better Business Bureau and maintains a 4.6-star average across 14 verified customer reviews. Located at 221 S. Chicago St. in downtown Joliet, the company supplies genuine replacement components to licensed contractors and educated DIYers throughout Will County and neighboring Kendall County. Their warehouse stocks heating, cooling, and refrigeration parts for virtually every major residential and light commercial system manufactured in the past three decades.

The business differentiates itself through a breadth of inventory rarely found at retail outlets. Unlike big-box stores that carry only common consumables, G.W. Berkheimer sources hard-to-find components including motors, capacitors, contactors, and specialized refrigerants. Their counter staff includes trained parts specialists who assist customers in identifying correct replacements using model numbers and serial data. The distributor also offers discounted pricing on bulk orders for professional contractors maintaining ongoing service routes in Joliet, Wilmington, and the surrounding townships.

Customer reviews highlight two staff members by name: Dave, who provided technical consultation to customer Omar Alani for identifying the exact replacement part needed for a malfunctioning system, and John, described by reviewer David K as always ready to help regardless of the request. Customer Brian notes the prices were consistently reasonable despite having purchased only a few items, while Anton Mcclellan specifically praised the fast, knowledgeable parts service.
