About Johnstone Supply
Johnstone Supply serves Concord, North Carolina as a heating equipment supplier with a 4.3-star rating drawn from 24 customer reviews. The location operates Monday through Friday from 7 AM to 5 PM, providing contractors and homeowners access to HVAC equipment, parts, and accessories during standard business hours. The store stocks a broad selection of residential and commercial heating and cooling systems, including split systems, packaged units, furnaces, and air handlers from major manufacturers.
The business differentiates itself through extensive inventory depth and contractor-focused distribution. Their website showcases products spanning variable capacity systems, multi-zone and single-zone mini-splits, gas and oil furnaces, evaporator coils, and field-installed accessories. Unlike retail-focused competitors, Johnstone Supply maintains relationships with installation professionals, enabling same-day parts procurement for urgent repairs. Extended warranty options provide additional value for long-term equipment protection.
