Johnstone Supply

Johnstone Supply operates as an HVAC equipment supplier in Springfield, Missouri, serving contractors and trades professionals throughout the Ozarks region including Branson, Joplin, and the surrounding Greene County area. The business maintains a 4.6-star rating drawn from 41 customer reviews, reflecting predominantly positive experiences with product availability and staff knowledge. Unlike retail home improvement stores, Johnstone Supply focuses exclusively on professional-grade heating and cooling components, drawing a customer base of licensed HVAC technicians, installers, and service technicians who return repeatedly for hard-to-find parts and specialized equipment.

The inventory breadth distinguishes this supplier from typical wholesale distributors. Beyond standard residential split systems and air handlers, Johnstone Supply stocks manufactured housing equipment, mini-split configurations including variable-capacity and multi-zone systems, and commercial packaged units. Their parts department carries OEM components ranging from compressors and motors to thermostats, ignition components, and refrigeration valves. Specialty offerings include geothermal units, evaporative coolers, high-velocity air systems, and portable air conditioning. This comprehensive selection allows contractors to source multiple equipment categories from a single supplier rather than managing accounts with multiple distributors.

Customer reviews repeatedly mention staff member Chris by name for his product knowledge and problem-solving ability. One reviewer describes how Chris located a condenser fan replacement within minutes during a holiday weekend when the caller had exhausted online options, providing pricing competitive with online retailers. Another homeowner credits Chris with identifying correct replacement parts over the phone using only a few diagnostic questions, then having the components ready upon arrival. A third reviewer notes the staff walked a non-contractor through selecting a 30+5 capacitor and answered installation questions, resulting in a successful DIY repair. The combination of technical expertise and willingness to assist customers directly contributes to the strong rating.
