Johnstone Supply

Johnstone Supply Store #578 operates in Cheektowaga, New York, as a heating equipment supplier serving Western New York contractors and tradespeople. With a 4.1-star rating drawn from 28 customer reviews, this distributor has built a reputation over years of operation as a go-to source for HVAC professionals seeking parts, equipment, and technical guidance. The store maintains standard business hours Monday through Friday from 7 AM to 4:30 PM, serving the Cheektowaga area and surrounding communities including Buffalo, Amherst, and the broader Erie County region. While not a traditional residential HVAC contractor, this supplier plays a critical role in the regional trades network by providing equipment and parts that professional installers rely on daily.

What distinguishes Johnstone Supply from typical supply houses is their comprehensive equipment inventory spanning multiple categories. The store stocks residential unitary systems including gas furnaces, oil furnaces, air handlers, and evaporator coils, alongside commercial packaged units and split systems. Their manufactured housing division serves that specific niche with dedicated furnace and coil inventory, while their mini-split offerings include single-zone, multi-zone, and variable capacity systems with field-installed accessories. The company maintains contractor account tools and a structured request system, reflecting their focus on serving professional trades rather than retail walk-in traffic. Their website cross-reference search capability helps contractors locate rare or specialized components quickly.

Customer experiences at this location reveal a team capable of exceptional service when circumstances align. Reviewer Brooks Brandt describes being welcomed and treated with respect despite not holding a contractor license, while steve c specifically credits Ryan with helping secure supplies and answering technical questions. Brian Adamczyk recounts how the team assisted with locating correct parts and even helped troubleshoot installation issues when a newer component didn't match the original. However, not all encounters prove positive, Conor Hawkins describes a frustrating Tuesday visit where he was turned away at 4:30 PM, leaving without heat at home. These mixed experiences suggest service quality may vary by timing and which team member assists customers.
