On a scorching summer day, portable air conditioners can make your room a refuge from the heat. Whether you are short on space, need a little extra cooling in a problem area or just want to keep your personal space at a constant, cool temperature, portable air conditioners are the solution. Unlike a window air conditioner that needs to be attached to a window or central air conditioners that can sometimes struggle to reach each corner of the house, portable air conditioners can follow you anywhere in the home. Room air conditioners are relatively easy to use, but here are the answers to a few common questions to help you use them efficiently.

- Can I use a portable air conditioner in a room without a window?
Just like all other air conditioning units, portable air conditioners need to have somewhere to release heat. A window is usually the most convenient way for portable air conditioning to vent, but there are other ways. For example, you can attach the exhaust tube to an air vent. Maybe the best idea would be to install a small vent leading directly outside.
- What is the difference between portable air conditioners and air coolers?
Air coolers use moisture, like a swamp cooler, to cool an area. This makes them quite a bit less effective in areas that are already humid, and they have a smaller cooling radius. On the other hand, they can often double as humidifiers. A portable air conditioner actually cools the air with a Freon system and generally has a larger cooling radius than an air cooler.
- Is it safe to leave portable air conditioners on during the night?
All portable air conditioners collect condensation as they cool. This is generally collected in a water tray in the air conditioning units themselves. If the water is about to overflow, the portable air conditioner will shut itself off. Generally, portable air conditioners have this same function if their air filters are about to overflow. The only real hazard is if you have plugged a portable air conditioner into an overused plug. Room air conditioners use a good amount of electricity and can cause a short if they don't have a dedicated plug. Otherwise, portable air conditioners are as safe as any other appliance.
- Can I lengthen the exhaust hose on a portable air conditioner?
While it is possible, extending the exhaust hose can often void the warranty on your air conditioning unit. In addition, if your workmanship isn't professional, it might be unsafe to lengthen the exhaust hose. If you would like to move your portable air conditioner, just move the exhaust hose or get two air conditioners.
