About Johnstone Supply
Johnstone Supply operates as a heating equipment supplier serving Shreveport, Louisiana, and surrounding communities with a 4.3-star average drawn from six customer reviews. The location maintains standard commercial hours Monday through Friday, offering in-store pickup and contractor account access for professionals sourcing HVAC components.
What distinguishes this supplier is their extensive inventory spanning multiple HVAC categories. The website showcases commercial single packaged units, residential split systems, mini-split configurations with variable capacity technology, plus full lines of gas and oil furnaces. They also stock manufactured housing equipment, air handlers with evaporator coils, and offer extended warranty programs for both residential and commercial applications.
Customer narratives reveal personalized service experiences that larger chains seldom provide. Reviewer Jaime Lozier described receiving four gas cans, including two pre-filled, during emergency evacuation following Hurricane Ida, assistance that proved essential for a displaced family. Staff member Josh quackenbos guided another customer through sourcing repair components at fair pricing, while Ken Armes noted workers located exact needed parts despite complex specifications. These accounts suggest technicians take ownership of finding solutions rather than defaulting to standard rejections.

The sole one-star review flags customer service concerns regarding communication and follow-through on picture documentation requests. Overall sentiment tilts decisively positive, particularly noting fair pricing and problem-solving orientation.
