Johnstone Supply

Johnstone Supply operates as a heating equipment supplier in Huntsville, Alabama, serving contractors who install and maintain HVAC systems throughout the Tennessee Valley. The location maintains standard business hours Monday through Friday from 7 AM to 4:30 PM and has earned a 4.6-star rating from 13 customer reviews. As a contractor-focused supply house, the business stocks parts and equipment that professional technicians need for same-day repairs and installations.

What distinguishes Johnstone Supply from other distributors is their commitment to turnaround speed and communication. Reviewers consistently mention waiting less than one minute for service, with staff often having parts pre-gathered before contractors arrive. The location works with Goodman brand equipment and handles warranty parts that other suppliers struggled to source, with one reviewer noting they saved a customer from a potential 2-3 month wait for air conditioning components.

Customer stories from reviews highlight specific technicians who deliver exceptional service. Ross has been praised for going above and beyond, including refusing tips while providing better service than major quick-service restaurants. Tommy and Haustin were recognized for immediately contacting Goodman to expedite warranty parts, then keeping the contractor informed throughout the process. Their responsiveness restored a customer's cooling system after another supplier had failed for over a month.
