Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in Louisville, Kentucky, serving contractors and homeowners from its location at 2301 Georgetown Road. With a 4.5-star rating accumulated across 27 customer reviews, the business has built a reputation for keeping extensive inventory on hand, many reviewers note the warehouse stays stocked with both common components and harder-to-find parts. The supplier serves the greater Louisville metro area, including Jeffersonstown and Prospect, providing same-day will-call service for professionals tackling residential repairs and commercial installations alike.

What distinguishes Johnstone Supply from typical supply houses is their dedication to contractor-only access along with a curated selection of residential equipment. The website confirms they stock Goodman brand furnaces, air handlers, and packaged units alongside comprehensive parts inventory spanning refrigeration components, electrical controls, and heat pump accessories. Multiple reviewers praise their next-day service for obscure parts that other area suppliers cannot source, and the counter staff demonstrates genuine product knowledge rather than simply fulfilling orders. Their HVACR parts selection includes specialized items like solenoids, sight glasses, and expansion valves, inventory depth that keeps professional crews moving on complex service calls.

Three recent reviewers describe scenarios where Johnstone Supply earned their loyalty. Angel Morrison highlighted a quick live unload after a parts run, while Donald Alexander described how the team directed him to a hard-to-source component they did not carry rather than losing the sale. Steve Knight specifically mentioned the counter staff's familiarity with Goodman equipment specifications, noting they consistently provide correct part numbers on first contact. The single one-star review from Richard Strange cited rude interaction, suggesting customer service consistency may vary depending on day and counter staff member.
