Claim This BusinessAbout Johnstone Supply
Johnstone Supply operates as a wholesale HVAC equipment distributor with a Raleigh location at Store 124, serving licensed contractors across North Carolina. The branch holds a 3.6-star rating drawn from 40 customer reviews, with a physical phone line at (919) 829-3511. Operating hours run Monday through Friday from 7 AM to 5 PM, with Saturday service until noon. This location specifically serves Raleigh, Durham, and the surrounding Triangle area, functioning as a trade-only supplier that does not sell directly to residential homeowners.
The distributor maintains an extensive inventory spanning multiple equipment categories visible on their product pages, including residential unitary systems, mini-split configurations, commercial packaged units, and specialty heating equipment. Their parts division carries OEM components covering major system categories: compressors, coils, motors, electrical controls, and refrigeration-specific items. The website indicates this location supports contractor account holders with access to training resources, monthly deals through eFlyers, and job placement services through their J-Team program. Stock includes notable equipment classifications such as geothermal units, high-velocity air systems, and through-the-wall condensing units.
Customer feedback highlights the parts counter staff, with one reviewer from Cool Change Heating and Air specifically praising the team for fair pricing and personalized service, noting that calling in to order parts feels like contacting familiar faces. A logistics review from March 2025 references the delivery entrance protocol and overnight parking availability, indicating the location accommodates commercial driver needs. Negative reviews primarily focus on the contractor-only policy, with multiple homeowners reporting they were unable to make purchases without an established contractor account.
What Customers Say
12 of 40 reviews give 1-star ratings, with homeowner buyers consistently denied purchases due to the contractor-only policy. In contrast, the 5-star reviews come exclusively from established HVAC company owners who praise fair pricing and parts-counter service. Service-related complaints mention warranty disputes and unresponsive management escalations.
