Johnstone Supply

Johnstone Supply has operated for decades as a wholesale heating equipment supplier in Harrisburg, Pennsylvania, earning a 4.8-star rating across 9 customer reviews. The location stocks parts and systems for contractors serving Harrisburg and nearby Camp Hill, maintaining the kind of inventory depth that keeps jobs moving without delays waiting on special orders. A consistent theme across positive reviews is the team is responsive, knowledgeable, and treats each contractor account as a partnership rather than a transaction.

What sets this branch apart is the Liberty program, which helped one reviewer grow his HVAC company to over 400k in his first year of business. The team handles cross-reference searches for hard-to-find parts across all equipment brands, sourcing components and formulating solutions that get clients operational with minimal downtime. Online account ordering with direct-to-house delivery eliminates trips to the counter, a feature that contractors managing multiple job sites consistently cite as a practical advantage.

Fred Cramer, who runs Fred's Heating and A/C in Camp Hill, specifically credits Jamie and the crew for going the extra mile on his orders. Steven McKeon, a newer contractor, worked directly with Matt Snyder to establish his account and praised how Snyder, Mark, and Richard pull together parts from multiple brands to solve problems other suppliers cannot. The combination of named staff expertise and reliable parts availability gives contractors a resource they return to project after project.
