Krope & Son Heating & Cooling, Inc

Krope & Son Heating & Cooling, Inc. has served Lisle and the surrounding DuPage County communities since 1957, making it one of the longest continuously operating family HVAC contractors in the Chicago metropolitan area. The company holds a 4.5-star average rating from 31 customer reviews, with recent feedback consistently praising their transparency, technical knowledge, and fair pricing. Commercial and residential customers alike rely on this company for heating and cooling equipment installations, routine maintenance, and emergency repairs.

As a Bryant Preferred Dealer, Krope & Son has direct access to industry-leading furnace and air conditioner models backed by manufacturer warranties that standard retailers cannot match. Unlike larger HVAC companies that juggle multiple brands, this contractor specializes exclusively in Bryant products, allowing technicians to develop deep expertise with each system they install and service. The company also provides professional indoor air quality assessments, helping homeowners address ventilation concerns, airborne particulates, and seasonal allergy triggers through targeted solutions.

Customer reviews repeatedly mention specific technicians by name. Tim, the owner, responded at 7:30 AM on Thanksgiving morning when a customer's heater failed during a holiday gathering. Another reviewer describes how the team arrived the same day during an emergency when no competing contractor would respond. Long-term customers highlight Zach's ability to diagnose complex error codes that stumped previous service calls, and multiple reviewers note their dogs warmed to the technicians during service visits.
