Johnstone Supply

Johnstone Supply operates as a commercial HVAC and refrigeration equipment distributor serving contractors across Vista and North County San Diego. The Vista branch relocated from Escondido in April 2022, bringing over a decade of regional supplychain expertise to its current location. With a 4.1-star rating accumulated from 22 customer reviews, the distributor has built a reputation among professional installers seeking specialized heating and cooling components.

The supplier maintains an extensive inventory spanning multiple equipment categories, including single-packaged units, split systems, and variable-capacity systems designed for both residential and commercial applications. Their catalog features mini-split configurations, multi-zone systems, air handlers with evaporator coils, and comprehensive gas and oil furnace selections. Notably, the business offers extended warranty packages and field-installed accessories that enable contractors to complete installations without sourcing additional components elsewhere.

Customer testimonials repeatedly credit specific team members for distinguishable service experiences. Greg receives consistent recognition for going above and beyond, with one reviewer noting his willingness to assist with any inquiry. Thomas is praised for order follow-through precision, while David is highlighted for researching obscure parts when called upon. The Vista location opened in 2022 with a well-organized showroom, satisfying a gap in professional contractor supply options across the region.
