Most Quiet Portable Air Conditioner Buyer Guide

Noise Level

If you need a quiet and portable AC, then you need to consider the dB. rating before making a purchase. Not all quiet portable units have the same level of quietness as some are quieter than others. So for your bedroom, you would need the silent performing AC unit to ensure you sleep well at night.

Generally, air conditioners produce sound at around 50 to 75 dB., but the silent ones are lower than 75 dB.

Size

The right size is needed if you must get the best results while cooling your room. using an air conditioner that isn’t up to capacity for your room size won’t cool it properly and you may still feel the heat.

An oversized air conditioner would leave your room feeling moist as the level of humidity would be high.

To know the right type of AC for your room, you need to find your room area and the BTU of the AC. The BTU gives you an idea of how much heat the AC can remove from the room. and so the higher the BTU, the more efficient your AC would be at keeping your larger room cool.

  • For rooms measuring up to 200 sq. ft., use an AC of 8,000 BTUs
  • For rooms measuring up to 300 sq. ft., use an AC of 10,000 BTUs
  • For rooms measuring up to 400 sq. ft., use an AC of 12,000 BTUs
  • For rooms measuring up to 600 sq. ft., use an AC of 14,000 BTUs

You would also need to increase the power of the AC you are getting if:

  • Your room has high exposure to sunlight
  • You would be using the AC in the kitchen
  • The rooms would be occupied by more than 2 people

Single Hose or Double Hose

Single hose air conditioners are quieter than the double hose and are the best types of air conditioners to use in cooling smaller rooms. With a single hose air conditioner, warm air is extracted through coils and passed out through the hose.

For double hose, there is an intake point for sucking the air in, getting it cool, and then sending it out. The cooled air is also used to keep the machine cool when it works and starts to heat up.

Dual hose units are more efficient in keeping larger rooms cool and in a shorter time. They are however more expensive. So depending on the area you intend to keep cool, make your choice accordingly.

Additional Features

Check that the portable AC you intend to buy has some additional features that improve your user experience. They include:

Dehumidifier: an air conditioner that also functions as a dehumidifier would help remove too much moisture from the air

Remote control: with remote control, you don’t have to leave your bed to alter the AC settings. You can choose whatever temperature or mode you want from the comfort of your bed, making it more convenient.

Programmable thermostat: with a programmable thermostat, your AC would better regulate your room temperature as it would go off when the pre-set temperature has been reached.

Heat and cool modes: with an air conditioner that can cool and heat your room, you wouldn’t need additional expenses during the different seasons of the year.
