About Johnstone Supply
Johnstone Supply operates as a heating equipment supplier in Nashville, Tennessee, earning a 4.3-star rating across 18 customer reviews. The branch has cultivated a strong reputation among both professional contractors and serious DIYers seeking quality HVAC components. Located at the Nashville facility, the business serves customers throughout Middle Tennessee, including the surrounding communities of Brentwood, Franklin, and Hendersonville, delivering equipment and supplies to projects ranging from residential replacements to commercial installations.
What distinguishes this supplier is their commitment to contractor-focused service. The Nashville team maintains an extensive inventory of HVAC products including pads, communication wire, and specialized components that other local suppliers often stock in limited quantities. Several reviewers explicitly mention the team's willingness to accommodate urgent needs, with one customer noting a staff member met them at the store on a Saturday evening to secure a condenser fan motor that restored cooling during an oppressive summer weekend.
The customer narrativesshared in reviews reveal consistent themes of personalized assistance. David Grodi's account details how he contacted the supplier when his AC condenser fan motor failed on a weekend, and someone staffed a cell phone specifically to meet him at 5:30 PM on Saturday afternoon so he could complete the repair that same evening. Lee D. and Larry Freemon both highlight staff members who think creatively to solve unusual problems, with Lee noting the team will go out of their way to ensure customers receive both the parts and technical guidance they need.
