Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in Fresno, California, serving contractors and trades professionals rather than residential homeowners directly. The business holds a 4.6-star rating compiled from 98 customer reviews, reflecting consistently positive experiences among those who have purchased equipment and parts through their counter. Their physical location at 3400 S Cherry Ave welcomes licensed HVAC professionals Monday through Friday from 7 AM to 5 PM, with weekend availability not offered at this particular branch. The supplier functions as a commercial distribution center, meaning homeowners seeking service would need to work with their own licensed HVAC contractor rather than obtaining direct installation or repair services.

What distinguishes Johnstone Supply from general-purpose hardware stores is their laser-focused inventory specifically for heating, ventilation, and air conditioning professionals. Their product catalog includes commercial packaged units, manufactured housing HVAC systems, mini-split configurations ranging from single-zone to variable-capacity multi-zone setups, and comprehensive residential unitary equipment including gas furnaces, oil furnaces, air handlers, and split systems. The supplier maintains an online contractor portal and mobile app allowing registered professionals to check stock, place truck-stock orders, and manage accounts digitally. This trade-only distribution model means every interaction is optimized for someone who understands technical specifications rather than a retail customer browsing for the first time.

Customer testimonials reveal a team of knowledgeable counter staff who develop long-term relationships with local contractors. Jerrod Betancourt specifically names Chuck, John, and Jake as individuals who provide what he describes as the best equipment selection and customer service in the area. Mark Morales reports doing business with this location multiple times weekly, praising the staff for professionalism, courteous behavior, and the ability to source rare parts often by the next business day. Jessica Akins notes that staff members remember her by name, highlighting the personalized attention that comes with repeat contractor relationships. The single one-star review from a contractor describes a frustration with parts availability and warranty handling, though this appears to be an isolated incident given the overwhelming positive sentiment across the remaining seven sampled reviews.
