Claim This BusinessJohnstone Supply has served the Clarksville, Tennessee area since 1947 as a wholesale distributor for HVAC and plumbing professionals. The location holds a 4.3-star average from 16 customer reviews and operates Monday through Friday from 7:30 AM to 5 PM. Staff members James and Jesse appear frequently in positive reviews, with multiple customers noting their willingness to go above and beyond for contractors and homeowners alike. The supplier serves Clarksville, Fort Campbell, Oak Grove, and surrounding Montgomery County communities.
As a wholesale distributor, Johnstone Supply stocks hard-to-find capacitors, refrigerants, and specialty HVAC components that typical retail outlets often cannot provide. Contractors maintain open accounts for convenient purchasing, while homeowners seeking parts for DIY repairs can receive hands-on guidance from counter staff. A notable policy restricts certain electrical parts and refrigerants to licensed professionals only, reflecting the companys commitment to code compliance and safe installation practices.
Brian Carnahan experienced an emergency during a summer heat wave when his AC capacitor failed. He called Johnstone minutes before closing and staff held the part while he drove across town, allowing him to restore cooling the same evening. Joshua Kennon attempted to source a repair component at two national home improvement stores without success before visiting Johnstone, where staff provided not only the correct part but also practical tips that helped him complete the repair without additional service calls. Both scenarios illustrate the hands-on expertise that differentiates this supplier from big-box retail environments.
All five-star reviews name James or Jesse by name, emphasizing their personal attention to contractor accounts. Three reviewers highlight emergency same-day part availability during urgent AC failures. The single negative review documents a refrigerant sale denial tied to EPA certification interpretation, which staff later clarified in a follow-up response.
