Johnstone Supply

Johnstone Supply operates from an Austin storefront at 55th Street, serving Central Texas contractors and homeowners with heating and cooling equipment since establishing a regional presence. The location earns a 3.9-star rating across 50 customer reviews, with hours stretching from 8 AM to 5 PM on weekdays and Saturday mornings. The Pflugerville branch supplements the Austin hub for customers traveling from Round Rock and surrounding communities.

Unlike big-box retailers, this supplier maintains a contractor-focused model while accommodating DIY homeowners at adjusted retail pricing. Their parts inventory spans major residential brands including gas furnaces, heat pumps, and mini-split systems alongside commercial refrigeration components. The wholesale pricing structure rewards licensed professionals, though same-day part acquisition attracts homeowners unwilling to wait for mail-order deliveries.

Customer experiences reveal a mixed reception. David Young praises the staff as consistently informative, calling it the best wholesale HVAC supplier in Central Texas. Rashi Race notes the convenience of walking in for immediate part needs rather than waiting for Amazon shipping. However, Stephanie Cruz recounts a frustrating episode where prior phone assurance gave way to an in-person denial based on contractor-only policies, highlighting the importance of confirming purchase eligibility before visiting.
