Johnstone Supply

Johnstone Supply has been a trusted HVAC equipment distributor serving the Columbus metro area for decades, operating from their location on the east side with a 4.6-star rating drawn from 26 verified customer reviews. The company primarily partners with licensed heating and cooling contractors across Westerville, Dublin, Reynoldsburg, and Gahanna, supplying the commercial-grade equipment and replacement components that professional technicians need for installations and repairs. Their inventory spans from residential furnaces and mini-split systems to commercial packaged units, making them a one-stop source for area contractors who depend on consistent parts availability and knowledgeable staff.

What distinguishes this distributor is their commitment to keeping specialized HVAC components in stock when other suppliers would leave technicians waiting on back orders. The Columbus location carries an extensive selection of evaporator coils, variable-capacity systems, refrigerant controls, and field-installed accessories that professional installers request daily. They also maintain an evolving catalog of commercial refrigeration equipment including reverse cycle chillers and geothermal units, positioning themselves as a resource for contractors tackling complex retrofit projects. This depth of inventory, combined with staff who understand technical specifications, reduces installation delays for the contractors they serve.

The customer reviews reveal several scenarios where the Johnstone team went beyond typical distributor service. One homeowner, Jason M, contacted them Saturday afternoon nearly closing time with an AC condenser part number and was offered secure phone payment with pickup from an exterior storage locker, avoiding any time pressure. Another reviewer, Kevin Sadeski, noted how they provided an alternative retail contact when their contractor-only policy initially applied. Robert Bauman highlighted that even when specific parts required overnight shipping, the team expedited orders to keep his projects on schedule. These examples illustrate their willingness to problem-solve across different customer situations.
