Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in Port St. Lucie, Florida, serving contractors and trade professionals across the Treasure Coast region. The business holds a 4.0-star rating derived from five customer reviews, reflecting a client base comprised primarily of licensed HVAC professionals and service companies. Located at the intersection of Florida's major commercial corridors, the supplier maintains weekday operations from 7:30 AM to 5 PM, Monday through Friday, with Saturday and Sunday reserved for will-call pickup by appointment only. This contractor-focused model distinguishes Johnstone Supply from typical residential HVAC companies.

The supplier maintains an extensive inventory spanning multiple equipment categories. Their residential lineup includes single-packaged units, split systems, and mini-split configurations featuring variable-capacity technology. Commercial offerings cover single-packaged and split-system models while their specialty section addresses manufactured housing applications. Air handlers and evaporator coils complement gas and oil furnace selections, with extended warranty programs available for purchase. Field-installed accessories and multi-zone systems round out a catalog designed to equip contractors completing installations across new construction and retrofit scenarios.

Customer interactions highlight responsive service during high-demand periods. Anthony, a team member referenced in a five-star review, guided a contractor client through a complex equipment order, providing technical specifications and ensuring the correct components arrived for a client installation. While one reviewer noted the absence of retail counter service, indicating the business operates on a pre-order and will-call basis, the majority feedback emphasizes product knowledge and order accuracy as consistent strengths.
