Claim This BusinessAbout Johnstone Supply
Johnstone Supply operates as a heating equipment supplier serving Winston-Salem and the surrounding North Carolina region, stocking residential and commercial HVAC components for professional contractors and alike. The location holds a solid 4.4-star average derived from 26 customer reviews, indicating generally satisfactory transaction experiences despite occasional friction points noted in feedback. Based on the storefront in Winston-Salem, this particular branch functions as a retail counter operation where customers can physically examine parts before purchasing, avoiding the guesswork often associated with online ordering for specialized heating components.
This distributor distinguishes itself through same-day delivery capability using a box truck, a logistical asset prized by HVAC technicians managing time-sensitive installations. The product catalog encompasses major residential brands including gas furnaces, oil furnaces, split systems, and mini-split configurations with variable capacity technology. They also carry extended warranty options and field-installed accessories, providing contractors a single source for both equipment and complementary mounting hardware rather than requiring multiple supplier relationships.
Customer accounts from reviews reveal several named professionals making meaningful service impressions. Dale earned recognition for physically assisting a customer transport purchases to their vehicle, demonstrating willingness beyond transaction minimums. Justin Gilley Hutchins was specifically cited by a reviewer for consistently pleasant interactions, suggesting certain staff members cultivate strong client relationships. Another reviewer detailed an instance where weekend support secured a difficult-to-locate AC component that another outlet could not provide, illustrating capacity to source unconventional inventory upon request.
What Customers Say
6 of 8 reviewers awarded five stars, praising product availability, knowledgeable counter staff, and same-day delivery. The two one-star reviews cite pricing disputes regarding refrigerant costs and account-restrictive policies for flex ducting materials.
