Looking for a portable air conditioner for this summer? Avoid these 5 common mistakes to make the right choice the first time.
Mistake #1: Underestimating the BTU
The most common mistake: choosing an air conditioner that is too small for the room. The result: it runs constantly without reaching the desired temperature, consumes more energy, and wears out quickly.
Simple rule: 400 BTU per m². For a 23 m² room, aim for 9000 BTU. Our complete BTU guide covers all cases.
Mistake #2: Ignoring the noise level
An air conditioner at 65 dB in a bedroom = ruined nights. For comfortable sleep, stay under 56 dB, ideally with a night mode ≤45 dB.
Mistake #3: Choosing one with an exhaust hose when renting
73% of French people are renters. An air conditioner with a hose requires blocking a window or drilling the wall — often prohibited in rentals.
Solution: windowless air conditioners that use evaporation. No installation needed. See our windowless range.
Mistake #4: Neglecting electricity consumption
A classic 9000 BTU air conditioner consumes 800-1200 W. Evaporative models like FrostAir™ consume only 65 W — 15× less.
Mistake #5: Buying without 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 customer service within 24 hours.
In summary
- Calculate BTU based on surface area (400 BTU/m²)
- Check the noise level (≤56 dB for the bedroom)
- Prefer windowless if you are renting
- Choose models with low consumption
- Buy with a 2-year warranty and free returns
