About Yandle-Witherspoon Supply, Inc.
Yandle-Witherspoon Supply, Inc. operates as a wholesale HVAC equipment supplier serving contractors and homeowners in Columbia, South Carolina, and surrounding communities. The business maintains a 4.6-star rating from five customer reviews, reflecting consistent service quality in the regional market. Their facility operates Monday through Thursday from 7 AM to 5 PM, with reduced hours on Friday until 4 PM, closed on weekends.
This supplier distinguishes itself through specialized indoor air quality solutions and generator systems rarely carried by standard contractors. Their catalog features American Standard heating and cooling equipment alongside Mitsubishi ductless systems and comprehensive ventilation components. The business stocks hard-to-find parts for aging heating systems, a capability that has earned specific praise from customers managing older property investments.
Customer feedback highlights the technical expertise of staff member Allen, who worked with a contractor to source components for an vintage gas heating system. This level of parts procurement assistance sets the supplier apart from typical distribution channels, serving as a resource bridge between homeowners, their HVAC technicians, and manufacturer supply networks.
What Customers Say
All five reviewers give 5-star ratings, with the sole detailed review mentioning Allen by name for securing rare parts for an older gas heater system.
