When you need cooling fast, you'll naturally wonder which of Germany's big DIY chains — OBI, Bauhaus, or Hornbach — is the best bet. The honest answer reframes the question: in a heatwave, the chain matters far less than which specific store near you has stock right now.
They all carry cooling ranges
OBI, Bauhaus, and Hornbach each stock a seasonal cooling range covering mobile air conditioners, fans, and evaporative air coolers, including common brands and models. The ranges overlap but aren't identical, and exact stock varies by chain and, crucially, by individual store. So while you can shop any of them for cooling, no single chain is universally "the one" for availability.
Why the chain matters less than the store
Here's the key insight: a heatwave sells out stock unpredictably across all chains, so loyalty to one brand can send you to a sold-out store while a different chain down the road has exactly what you want. What actually determines whether you get cooling today is store-level availability near you, not which logo is on the building. The right strategy is to compare across chains by what's genuinely in stock.
Compare by live stock, not by brand
Instead of visiting each chain's website separately and trusting national "in stock" labels, check live, store-level availability for the product you want by postal code. That shows which nearby stores — of any chain — have the unit now, so you can reserve wherever it's genuinely available. Our live stock finder does this for the OBI network, and the same principle applies whenever you compare options: chase stock, not brand.
Pickup and convenience
All three chains offer in-store pickup, which — as covered in our click & collect guide — is usually the fastest, most reliable way to buy in a heatwave. Whichever chain has your unit in stock, reserve it online and collect the same day rather than risking delivery delays. Proximity and current stock should drive your choice more than chain preference.
How to decide
- Decide what you want — a mobile AC, fan, or air cooler.
- Check live stock by postal code across your options.
- Reserve at whichever nearby store actually has it.
- Set an alert if everything's sold out, so you catch the next restock anywhere.
The takeaway
OBI, Bauhaus, and Hornbach all sell cooling, but in a heatwave the winning move is to compare live, store-level stock near you rather than committing to one chain. Chase the unit that's genuinely in stock and reserve it. Start by checking what's in stock near you.
