Looking for a portable air conditioner this summer? Avoid these 5 common mistakes to make the right choice the first time.
Mistake #1: Choosing too few BTUs
The most common mistake: choosing an air conditioner that is too small for the room. The result: it runs continuously without reaching the desired temperature, uses more energy, and wears out quickly.
Simple rule: 400 BTU per m². For a 23 m² bedroom, aim for 9000 BTU. Our complete BTU guide covers every situation.
Mistake #2: Ignoring the noise level
A 65 dB air conditioner in a bedroom means ruined nights. For comfortable sleep, stay below 56 dB, ideally with a night mode of ≤45 dB.
Mistake #3: Choosing an exhaust-hose model when renting
73% of French people are renters. An air conditioner with an exhaust hose requires blocking a window or drilling into the wall—often prohibited in rental properties.
Solution: a windowless air conditioner that uses evaporation. No installation required. See our windowless range.
Mistake #4: Overlooking electricity consumption
A standard 9000 BTU air conditioner uses 800–1200 W. Evaporative models like the Silent 3-in-1 use just 65 W—15× less.
Mistake #5: Buying without a warranty or return policy
All our Coldest Breeze air conditioners include a 2-year warranty, free 14-day returns, free delivery in France within 4–7 days, and French-language customer service within 24 hours.
In summary
- Calculate BTUs based on the room size (400 BTU/m²)
- Check the noise level (≤56 dB for a bedroom)
- Choose a windowless model if you are a renter
- Prioritize low-consumption models
- Buy with a 2-year warranty and free returns
