About Johnstone Supply
Johnstone Supply operates as a heating equipment supplier in Lakeway, Texas, earning a 4.1-star rating across 10 customer reviews. The store maintains Monday through Friday hours from 8 AM to 5 PM, with Saturday availability until noon and Sunday closures. This location functions primarily as a contractor distribution hub, serving professional HVAC technicians rather than individual homeowners. The Lakeway address places this supplier within the greater Austin metropolitan area, providing equipment access for professionals handling residential and commercial heating projects throughout the surrounding Texas communities.
The supplier differentiates itself through a contractor-only distribution model, offering account-based pricing that provides significant savings to licensed professionals. Their website showcases an extensive equipment catalog spanning single packaged units, split systems, and mini-split systems for both residential and commercial applications. The product lineup includes air handlers, evaporator coils, gas furnaces, and field-installed accessories, with specialty categories for manufactured housing and variable capacity systems. This focused approach allows the business to maintain specialized inventory tailored specifically to professional installation requirements.
Customer experiences reveal varied interactions depending on customer status. One reviewer described being guided to an alternative seller when seeking parts as a homeowner, while another praised the knowledgeable staff for contractor-specific support. A negative review detailed a $75 capacitor purchase that exceeded typical online pricing, with a strict no-returns policy noted at the time of transaction. These accounts reflect a business model oriented toward professional contractor accounts rather than retail consumer sales.
What Customers Say
3 of 5 reviewers awarded 5-star ratings praising service quality, while 1 reviewer flagged pricing concerns regarding parts purchased without a contractor account. Positive feedback highlights knowledgeable staff and guidance toward appropriate sellers.
