Johnstone Supply files its address as 7500 Old Seward Highway Suite A, Anchorage, AK 99518. The block sits in the south Anchorage commercial corridor between Tudor and Dimond. Johnstone is a national HVAC wholesale chain with the local franchise serving Alaska contractors — this is a trade counter, not a retail consumer-facing store.
How HVAC wholesale works
HVAC parts wholesalers like Johnstone sell to licensed contractors at trade pricing — not directly to consumers. Contractors maintain accounts, pick up parts in person or via daily delivery routes, and stock common items on their trucks. The wholesaler model keeps Alaska contractors stocked for residential and commercial service calls.
Parts categories carried
Johnstone’s Anchorage location stocks the parts needed for Alaska’s mechanical mix: hydronic boiler controls, expansion tanks, circulation pumps, baseboard radiators, oil-furnace burner components, refrigerant for both commercial and residential systems, ductwork and sheet metal, thermostats, and control wiring. Specialty cold-climate items (heat-tape, freeze-resistant fittings) are kept in stock.
For consumers: working with contractors who source here
If a residential HVAC contractor in Anchorage sources from Johnstone, that’s a good signal — it means they have access to manufacturer-warrantied parts rather than knockoff supplies from non-authorized channels. Consumers don’t shop at Johnstone directly but benefit from a contractor with a Johnstone account.
