Johnstone Supply

Johnstone Supply operates from its Providence location as a heating equipment supplier serving the center of Rhode Island, with an inventory spanning residential furnaces, split systems, mini-splits, and evaporator coils. The business maintains a 4.5-star rating across 22 customer reviews, and the counter staff includes Spanish-speaking associates who assist both licensed contractors and DIY homeowners. Saturday hours from 8 AM to noon accommodate those unable to visit during weekday business hours, and the warehouse stocks major residential brands including gas and oil furnaces. The facility serves Providence, Cranston, Warwick, and surrounding communities.

The distinction here lies in the counter staff experience and inventory depth. Reviewers consistently praise the knowledgeable team, with Michael Paliotta noting the "huge inventory usually in stock on location" and the staff's ability to work with customers on pricing and specifications. Unlike some wholesale outlets that restrict sales to licensed contractors only, Johnstone Supply maintains retail access for homeowners, though certain products require account standing. The commercial and specialty divisions round out offerings for field-installed accessories, multi-zone systems, and manufactured housing units.
