The catch with owning

Too hot to sleep, and owning one is its own headache?

Most flats in Germany have no air conditioning, and buying your own unit sounds simpler than it ends up being. You haul a heavy box up to the fourth floor, guess which window seal fits, and hunt for somewhere to store it eight months a year. Often there's a deposit on top of that. The rules aren't really the hard part. The hassle of owning is.

How the Sommer-Abo works

How it works

  1. Tell us about your place

    Room size, window type, noise-sensitive neighbours. Takes two minutes.

  2. We deliver and set it up

    A quiet unit sized for your room, window seal included. We fit it, with no drilling.

  3. We collect it from mid-September

    We book your collection slot with you in August. Nothing to store, no deposit. And if it breaks, you get a replacement within 3 working days.

Prefer to buy? That runs through our partner link, and if you like, we'll set it up at your place for 149 €.

Why KlimaLegal

  • Only permit-free units

    Portable monoblocks, window units and permanently sealed mobile splits are all permit-free. No grey areas.

  • Quiet enough for the night

    We filter by noise level. On the Premium unit the compressor sits outside, so it stays quiet enough for the bedroom.

  • No deposit, fast replacement

    You pay no deposit. And if a unit fails, you get a replacement within 3 working days.

The stakes

This isn't hyperbole

In recent summers around 3,000 people in Germany died from the heat each year — in the worst years (2018 and 2019) it was about 7,000.

Only about 1 in 5 German households has air conditioning, and cost is the number one reason people go without.

FAQ

Common questions

Do I really not need a permit?

No. We only bring units you're allowed to use as a renter: portable monoblocks, window units and permanently sealed mobile splits. Those don't fall under the rules for fixed split systems.

Does my landlord have to agree?

Not for mobile units, since nothing is fixed to the building and we don't drill. For window solutions, it's still worth a quick look at your rental contract first.

What does the Sommer-Abo cost?

Sommer-Abo Standard: €89/month, 4-month minimum term, plus €189 for delivery, setup and collection — €545 for the whole season. Sommer-Abo Premium “Quiet”: €199/month, 4-month minimum term, plus €299 for delivery and professional installation — €1,095 for the season. No deposit.

Why a 4-month minimum term?

Because the Abo covers the whole season: 1 June to 30 September. The unit stays with you all summer and we collect it from mid-September — so you pay four monthly instalments and never a month in which the unit isn't at your place. The one-time fee (€189 on Standard, €299 on Premium) covers delivery, setup or professional installation, and the collection at the end.

How do delivery and pickup work?

We bring the unit to you and set it up: with a fitted window seal on the Standard Abo and professional installation on the Premium. For the collection we book a slot with you in August, and pickups start in mid-September. There's nothing for you to store.

Can I buy one instead?

Sure. You'd buy through our partner link, and if you like, we'll set it up at your place for 149 €. The partner shop is always the seller and carries the warranty.
