Frequently Asked Questions
What size AC do I need for my room?
Good question! It depends on the square footage. For a small room (under 350 sq.ft), the BLACK+DECKER 8K BTU might do the trick. Mid-sized rooms (around 400-500 sq.ft) could benefit from the Shinco 12K BTU or Whynter Dual Hose. For large rooms (up to 700 sq.ft), check out the SereneLife 14K BTU model. The Dreo AC516S is also great for large areas and has smart features thrown in.
What’s the difference between single-hose and dual-hose ACs, like the Whynter?
Single-hose ACs pull air from inside to cool and vent the hot air outside, which can create negative pressure. Dual-hose units, like the Whynter, draw air from outside to cool, making them more efficient and preventing hot air from being pulled back in. If you need max cooling for your money or suffer from allergies, dual hose are the way to go.
How loud are these air conditioners? I need something quiet!
Noise levels vary. The Dreo AC516S is the quietest at 46dB. The Whynter Dual Hose is also respectable at 51dB. The SereneLife 14K BTU is the loudest at 57dB. The Shinco will be louder on MAX setting.
Do any of these ACs require me to empty a water tank? I’d rather avoid that.
The Dreo AC516S has drain-free operation if humidity is under 85%! The BLACK+DECKER 8K BTU and SereneLife 14K BTU have auto-evaporation features, which reduces the need to drain water. The Whynter Dual Hose has an auto-drain function too.
Will these air conditioners work with my windows? My window slides horizontally.
Each AC comes with a window kit. The Dreo AC516S has a universal kit that fits windows from 17″ to 53″. The BLACK+DECKER, Shinco, SereneLife, and Whynter also include window kits, designed to fit standard windows. Make sure to double-check the specific requirements for each model before purchasing. Also, consider how easily the window kit assembly functions and installs!
