Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in Houston, Texas, holding a rating of 3.9 stars across 102 customer reviews. The business maintains weekday hours from 7 AM to 5 PM, with abbreviated Saturday availability from 8 AM to noon, and remains closed on Sundays. This schedule aligns with typical contractor supply house operations in the metro area, serving both professional technicians and homeowners seeking specialty heating components.

The company distinguishes itself through a robust inventory of hard-to-find replacement parts, a capability highlighted by multiple reviewers.

One reviewer recounts Manny's assistance with an outdoor condenser purchase in 2019, while another notes Brian Baird consistently goes above and beyond for regular customers. A recent Saturday scenario involved a customer successfully placing an order just before closing and retrieving it hassle-free from a locker system, demonstrating flexible service options.
