ILLCO Inc.

ILLCO Inc. operates as an HVAC parts wholesaler in Countryside, Illinois, holding a 4.5-star rating derived from 81 customer reviews. The business maintains Monday through Friday operations from 6:30 AM to 5:00 PM, with Saturday hours extending from 8:00 AM until noon. Located at (708) 579-5600, the company serves contractors and DIY homeowners seeking replacement components including motors, furnace ignitors, and refrigerant. Reviewers indicate the business carries parts for multiple HVAC brands and maintains inventory that addresses both residential and light commercial equipment needs.

Customers describe ILLCO as a supplier where experienced staff members assist with identifying correct parts, though multiple reviews note pricing sits above independent hardware stores. The wholesaler maintains a 25% restocking fee on returned items, a policy mentioned in critical feedback. Several reviewers cite ILLCO as their primary source for hard-to-find components, with one customer noting twelve years of reliance for refrigerant and specialty parts. The business does not appear to offer installation or repair services, positioning itself as a supply channel rather than a service contractor.

Customer narratives highlight specific staff interactions. Tim and another associate assisted a customer locate a furnace ignitor that resolved a heating issue. Another reviewer describes ILLCO as helpful during emergency calls for refrigerant, though the same review references inconsistent phone experiences including dropped calls and extended hold times. A critical review alleges rude treatment during initial visits, while a subsequent interaction received praise for improved assistance. These mixed experiences suggest service quality varies by individual staff member and timing.
