Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in White Plains, New York, serving contractors across Westchester County and the lower Hudson Valley. With 41 verified customer reviews producing a 4.6-star rating, the distributor stocks residential and commercial HVAC equipment including furnaces, split systems, mini-splits, and evaporator coils. The store maintains weekday hours from 7 AM to 4 PM and opens Saturday mornings, enabling same-day parts pickup for contractors managing emergency service calls.

This supply house distinguishes itself through its contractor-focused infrastructure. The location carries an extensive inventory of field-installed accessories and multi-zone systems that smaller supply houses often cannot stock. Their JS Solutions platform provides integrated ordering tools, while the Education and Training resources help contractor customers stay current on evolving equipment technologies. The warranty request system and account management tools streamline parts replacement for registered professionals.

Customer feedback highlights the responsiveness of specific staff members when time-sensitive situations arise. Contractor reviewer Comfortable Air recounts how salesman Chris stayed past closing on a Saturday to ensure refrigerant pickup for an urgent job. Another reviewer credits Lonnie with rapidly locating a needed component and expediting the order, noting the difference that knowledgeable counter staff makes when serving end-use customers who cannot afford downtime.
