About Johnstone Supply
Johnstone Supply has operated as a heating equipment distributor in Toledo, Ohio since 1987, serving contractors across Lucas, Wood, and Ottawa counties. The company maintains an A+ rating with the Better Business Bureau and stocks over 2,400 SKUs of residential and commercial HVAC equipment. With 19 verified customer reviews averaging 4.9 stars, the supplier has built a three-decade reputation among area installers and service technicians. Their warehouse location on Airport Highway provides will-call and bulk delivery for licensed contractors conducting installations and repairs throughout the greater Toledo region.
Unlike retail HVAC showrooms, Johnstone Supply operates as a pro-only distributor, contractors must establish accounts and provide valid license numbers before purchasing. This model ensures bulk inventory stays available for professional jobs rather than walk-in traffic. The company carries an extensive line of residential unitary systems, including single-packaged units, split systems, and mini-split configurations. Their commercial division handles single-packaged units and field-installed accessories, while specialty lines include manufactured housing components and extended warranties. Technicians appreciate the in-stock parts policy, reducing project delays when materials arrive pre-staged.
Customer reviews repeatedly highlight specific technicians who deliver under pressure. Timothy Estes praised the team for having a hard-to-find ignition component in stock during a same-day emergency call. Victor Michalak noted the quick-service turnaround during a heat wave weekend when multiple area companies facedbacklogs. Yehudah Bernath described the staff as helpful when contractors needed guidance on matching evaporator coils with existing furnace configurations. The single negative review, from a homeowner seeking retail parts, underscores that this supplier serves the trade professional community rather than residential do-it-yourselfers.
What Customers Say
Eight customer reviews posted between 2023-2024 show 87.5% five-star ratings, with no ratings below three stars.
