Coolhaus
A first-time AC buyer's companion for Europeans: snap photos of your apartment and it recommends right-sized units, compares them on EU seasonal efficiency ratings, drafts a landlord-permission letter for renters, and books vetted installers in your city.
European first-time AC buyers, especially renters in Germany, France, the UK, and the Netherlands
- Photo-based room measurement with right-sized unit recommendation in BTU/kW

A Guardian feature, an Elon Musk X post, and AfD/Le Pen rhetoric are turning AC from a lifestyle buy into a politically visible decision; record European heatwaves are pushing first-time buyers in countries where adoption still sits at 6-24% of homes.
German household AC penetration rose from 13% to 19% in 2024 with European market value up 4.3%, but Cooling Post and BSRIA report 2024 sales in France, Germany, and the UK as 'disappointing' — real first-time demand coexists with hesitant conversion.Highs and lows of European AC sales in 2024 - Cooling Post ↗Europe Air Conditioners Market By Product Type ↗
Available tools are US-focused generic BTU/sizing calculators (hvacbase, accalculator, omnicalculator); no integrated photo-to-size, EU SEER/SCOP comparator, multi-country landlord letter generator, and vetted installer booking app exists for European first-time buyers, especially renters.Air Conditioner BTU Calculator: What Size AC Do You Need?

Direct unit sales (€500–€3000) plus installation fees (€500–€2000) and growing EU labor shortage create room for affiliate/referral economics, but renters face landlord-approval friction and 2024 sales softness in core DE/FR/UK tempers willingness-to-pay.Green Growth: Europeans Are Embracing Air Conditioning | BCG ↗Europe turns up the cool: a hot summer sparks a chilling boom ↗
Climate-driven demand, EU ecodesign/energy-label regulation (SEER/SCOP) creating a perpetual comparison problem, and an EU-wide AC installer shortage all point to multi-year tailwinds beyond 2030.Air Conditioners and Comfort Fans - European Commission ↗Green Growth: Europeans Are Embracing Air Conditioning | BCG ↗
LLM-generated multi-language landlord letters and EPREL/SEER lookup are trivial; photo-based room sizing is moderately hard, but curating vetted installers city-by-city across DE/FR/UK/NL is heavy operations work that competes with players like Coolblue and local HVAC directories.
