Johnstone Supply in Columbia — What to Find and How to Shop There
What Johnstone Supply Columbia carries and who shops there
Johnstone Supply is a wholesale plumbing and HVAC distributor located in Columbia that sells to contractors, builders, and licensed professionals rather than to the general public. The store stocks pipes, fittings, valves, water heaters, furnaces, air conditioning units, ductwork, refrigerant, tools, and replacement parts for residential and commercial systems. If you are a licensed plumber or HVAC technician, you can open an account and order materials for job sites. If you are a homeowner looking to buy a single water heater or repair part, you will need to work through a licensed contractor who has an account with them.
Johnstone Supply operates as part of a national network of over 100 locations, all following the same wholesale model. The Columbia branch serves the Midlands region and maintains inventory for same-day or next-day pickup on many items. Contractors often choose Johnstone because the store stocks both common materials and hard-to-find specialty items, and because account holders can order online and pick up at the counter without waiting for delivery.

How to open an account if you are a licensed contractor
To open a wholesale account at Johnstone Supply Columbia, you will need to provide proof of your contractor license, a business tax ID or EIN, and a valid form of business identification. The store accepts applications in person at the location or by phone. You can also start the process online through the Johnstone Supply website and complete the paperwork at the Columbia branch.
Once your account is approved, you gain access to contractor pricing, the ability to order online for pickup, and credit terms if your business qualifies.

What to expect when you visit or call the Columbia location
The Johnstone Supply Columbia store operates during standard business hours and is staffed by people who know plumbing and HVAC systems. If you call with a question about a specific part or material, the staff can often tell you whether it is in stock and set it aside for you. If you visit in person with your account information, you can browse the showroom, pick up materials, and ask questions about product compatibility or installation.
The store also handles special orders for items not in regular stock. Lead times vary depending on what you need, but the staff can give you an estimate when you place the order. Many contractors build relationships with the team at their local Johnstone location because the same people are there regularly and learn what materials each contractor tends to need.
Ordering online for pickup or delivery
Account holders can log into the Johnstone Supply website, search for materials by part number or product type, and place orders for pickup at the Columbia location. Online ordering is useful when you know exactly what you need and want to confirm it is in stock before you drive over. Most orders placed before mid-afternoon can be picked up the same day; orders placed after hours are typically ready the next morning.
For larger orders or materials needed on a specific job date, you can also arrange delivery to your job site. Delivery fees and timing depend on the size of the order and how far the location is from the Columbia store. The staff can discuss delivery options when you place your order.

Why contractors choose Johnstone over retail hardware stores
Johnstone Supply offers contractor pricing, which is lower than retail prices at big-box hardware stores, because they buy in volume and sell to professionals who purchase regularly. The store also stocks commercial-grade equipment and specialty items that retail stores do not carry, such as high-capacity water heaters, commercial refrigerant, or hard-to-find replacement parts for older systems.
Contractors also value the expertise of the staff and the ability to build an account relationship. If you are a plumber or HVAC technician who works in Columbia regularly, having a Johnstone account means you can order materials quickly, get competitive pricing, and work with people who understand your business.

You do not need to visit Johnstone yourself; the contractor handles all ordering and pickup.
If you are looking for a contractor, ask friends or neighbors for recommendations, check online reviews, or contact the South Carolina Contractors Licensing Board to verify that a contractor holds a current license. A licensed contractor will have the account access and expertise to source the right materials for your job.
