Johnstone Supply

Johnstone Supply has anchored its North Hills Pittsburgh branch within the local contractor community for over a decade, earning a 4.1-star average across 23 verified reviews. As a wholesale distributor rather than a retail storefront, this location serves exclusively licensed HVAC technicians and trades professionals sourcing equipment and components for active installations across Pittsburgh, the North Hills suburbs, and surrounding Allegheny County job sites. The branch operates Monday through Friday from 7:30 a.m. to 4 p.m., aligning with standard contractor scheduling needs rather than homeowner service calls.

Unlike a typical contractor selling labor, Johnstone Supply functions as a wholesale parts depot stocked to serve active installations. The Pittsburgh branch carries commercial single-packaged and split systems, residential gas and oil furnaces, mini-split multi-zone and variable-capacity setups, geothermal units, infrared heaters, and manufactured-housing equipment. For parts procurement, technicians tap accumulators, expansion valves, compressor assemblies, heat exchangers, ignition components, and refrigerant controls. The branch also supports ongoing professional development through a posted training calendar, helping contractors stay current on equipment advances and certification requirements.

Reviewers repeatedly name specific staff members who go beyond standard counter service. Richard Nock notes working with John, Alex, and Joe for more than ten years, describing the relationship as consistently professional. Sonny P credits the same team, along with Cal, for handling urgent material needs during active projects. Anthony Geiger specifically calls out the branch's stock depth as a practical advantage, while Matthew Carr's brief endorsement of Joe Dirt reflects the personal rapport that keeps contractors returning. One dissenting voice from Virtual Life reported pricing inconsistencies and profanity from staff, recommending the Strip District branch instead for customers prioritizing price transparency and polished counter etiquette.
