Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in Gulfport, Mississippi, serving both DIY homeowners and licensed HVAC contractors. Located at store220 in the Johnstone Supply network, this location maintains standard commercial hours Monday through Friday from 7:30 AM to 5:00 PM. The supplier has accumulated 25 customer reviews yielding a 3.6-star average rating, positioning it among mid-tier options in the Gulfport area for HVAC components and systems.

This supplier differentiates itself through an extensive catalog spanning residential and commercial equipment. The website showcases single packaged units, split systems, mini-split systems, variable capacity systems, multi-zone configurations, and manufactured housing solutions. They stock gas furnaces, oil furnaces, air handlers, evaporator coils, and field-installed accessories. Extended warranty programs are available, and the operation maintains contractor-specific resources including authorized buyer list management and professional account access.

Customer experiences reveal mixed service quality. A positive review from Alyssa Tapp describes an excellent experience working with Cameron and Phillip during an AC system replacement, then returning after a house fire required duct work replacement where Cliff facilitated needed materials. A commercial contractor identified only as Family Heating and Air praises the location for maintaining stock levels. However, multiple one-star reviews cite strict no-return policies even on new, unopened products purchased within 24 hours, and concerns about markup on certain components.
