Johnstone Supply

Johnstone Supply operates as a wholesale distributor in Santa Rosa, California, serving licensed HVAC contractors rather than residential homeowners. With 9 customer reviews contributing to a 3.2-star rating, the location functions as a trade-only supply house where purchases require valid contractor licensing verification. The store maintains standard commercial hours from 7 AM to 5 PM Monday through Friday, closed on weekends. Located at Store 98 in the Johnstone Supply network, this branch distributes HVAC equipment, parts, and accessories exclusively to professional installers and service technicians within the Northern California contractor community.

The Santa Rosa distribution center offers an extensive inventory of residential and commercial HVAC equipment drawn from the website text: split systems, single packaged units, mini-split systems, variable capacity systems, multi-zone configurations, gas and oil furnaces, air handlers, evaporator coils, and extended warranty options. They stock manufactured housing units and field-installed accessories. The branch promotes contractor account access, cross-reference search tools for parts identification, and commercial solutions. However, the trade-only business model means DIY homeowners and unlicensed buyers cannot make purchases directly from this wholesaler.

Named technicians appear consistently across the positive reviews, with specific scenarios documented. John assisted a contractor during an emergency order when another supplier failed, personally monitoring the shipment to ensure on-time delivery. Tyrone and John were recognized for their product knowledge and quick assistance with parts location. One reviewer noted the front counter clerk helped locate an essential component that could not be found elsewhere. Customers calling for same-day emergency parts should verify contractor licensing requirements before visiting.
