Thermal Supply Inc lists its address as 4660 Gambell Street, Anchorage, AK 99503. The address matches Refrigeration Unlimited’s listing — either co-located, building-shared, or affiliated entities at the same midtown Anchorage block. A second HVAC wholesaler at the same address indicates a small ecosystem of trade-counter and specialty supply businesses serving Alaska contractors.
Why multiple wholesalers cluster
Trade-counter businesses often co-locate because their customers (HVAC contractors) make recurring stops to multiple suppliers in a single morning errand run. Co-located or adjacent wholesalers reduce the contractor’s driving time and let them split orders across vendors based on parts availability and pricing.
The specialty parts side
Thermal Supply, similar to other HVAC wholesalers, carries the components needed for Alaska’s heating-heavy mechanical market: boilers, furnaces, hydronic components, ductwork, refrigerant, and the specialty cold-climate items (frost-resistant fittings, heat tape, freeze-stat controls) that lower-48 wholesalers may not stock in depth.
Consumer relevance
Residential customers don’t purchase directly from Thermal Supply but benefit indirectly when their HVAC contractor has access to the right parts in stock. A contractor sourcing from local Anchorage wholesalers can typically diagnose-and-fix on the first visit rather than ordering parts from out-of-state and returning for a second visit days later.
Getting to 4660 Gambell Street
The address is accessible from the Seward Highway via Tudor Road or 36th Avenue. The trade counter is at the front of the building.
