Johnstone Supply

Johnstone Supply operates as a heating equipment supplier serving New Hyde Park and surrounding Nassau County communities. The location maintains a contractor-only distribution model, meaning they sell exclusively to licensed HVAC professionals who have established accounts. This policy ensures that residential customers must work through their chosen contractor to purchase equipment, a model that several reviewers confirmed during their interactions. The store operates Monday through Friday from 7 AM to 5 PM, with Saturday hours from 8 AM to 12 PM, and currently holds a 3.2-star rating from 43 customer reviews.

The supplier differentiates itself through specialized brand partnerships and trade-specific programs. As an Amana dealer, they stock residential and commercial HVAC equipment including split systems, mini-split systems, furnaces, and air handlers. Their contractor tools platform offers features like quote approval forms, RGA requests, and OE Touch account management. The training calendar and loyalty rewards program provide ongoing value for professional accounts, while the EZ-Locker Pick Up service allows contractors to retrieve orders without entering the store.

Customer experiences at this location vary considerably. Positive reviewers praise specific staff members, with Juan receiving recognition for helping find the right part and explaining technical details clearly. Another reviewer noted that staff verified their licensing before selling equipment, describing a safety-focused policy. However, negative reviews cite inventory inconsistencies and confrontational interactions, including one report of discriminatory attitude from a staff member named Brendan Palmar. A contractor reviewer mentioned depending on this branch despite frustrations due to its proximity to their service area.
