Johnstone Supply

Johnstone Supply operates as a commercial HVAC equipment supplier located at the Grand Prairie store serving the greater Dallas-Fort Worth metroplex. With a 4.6-star rating compiled from 19 customer reviews, the company has established itself as a trusted parts source for contractors and DIY homeowners throughout Tarrant County. The retail location at Store 584 maintains weekday hours Tuesday through Friday from 7 AM to 5 PM and Saturday hours 8 AM to 12 PM, providing walk-in access to HVAC components that increasingly require special ordering through big-box retailers.

What distinguishes Johnstone Supply from commodity competitors is its depth of inventory across specialized categories including mini-split systems, variable capacity systems, multi-zone configurations, and manufactured housing units, product lines that demand technical knowledge most retail associates cannot provide. The store carries extended warranty options on residential unitary equipment and maintains dedicated commercial inventory including single packaged units and split systems alongside the standard gas and oil furnace categories. This breadth enables procurement of complete system solutions rather than isolated component replacement.

Customer feedback specifically identifies Cecilia (also referenced as Miss Cece) and Eddie as staff members who consistently resolve complex parts identification challenges. Reviewers describe scenarios including same-day part availability during emergency situations, compatibility verification for aftermarket installations, and assistance locating obscure components that other suppliers could not source. Keaton Tann's review explicitly notes fulfillment of orders and parts acquisition that required going beyond standard supplier capabilities.
