Johnstone Supply

Johnstone Supply operates as a wholesale HVAC equipment distributor serving professional contractors in the Franconia, Virginia region. The Franconia location holds a 4.2-star rating compiled from 15 customer reviews, with business hours extending from 7 AM to 4:30 PM on weekdays. This supplier functions exclusively as a trade-only distributor, meaning residential homeowners cannot make direct purchases and must work through licensed HVAC contractors to acquire equipment. The company maintains a comprehensive inventory spanning residential and commercial heating and cooling systems, including split systems, mini-split systems, furnaces, air handlers, and evaporator coils.

The distributor offers contractor account access and specialized contractor tools through its website, positioning itself as a resource for professionals seeking bulk equipment procurement. Website inventory includes manufactured housing units, field-installed accessories, multi-zone and single-zone systems, variable capacity systems, extended warranties, and specialty HVAC products. The company provides both single-packaged units and split system configurations across residential unitary categories, supporting contractors handling projects ranging from new installations to replacement units.

Customer feedback highlights inconsistent experiences across Johnstone Supply locations. Positive reviews cite friendly staff and efficient service, with reviewers like Cristofell De la Rosa Paulino praising availability and Jose Rodriguez noting amazing people. However, the Alexandria branch received criticism for failing to support a contractor needing six 5-ton units for an urgent project, while the Sterling location stepped in to fulfill the order. A separate reviewer reported being refused service when inquiring as a homeowner, illustrating the trade-only business model.
