Factors to consider before buying a portable air conditioner


If you are thinking to buy a portable air conditioner then this article is very important for you before buying any portable air con unit you should go through this article as here we have listed the best factors that you must consider before buying a unit. Nowadays portable air conditioners are in demand as they are providing many features compared to a traditional air conditioner but this doesn’t mean that you can buy any portable ac unit without considering these important factors.

1. Energy Efficiency

This is the factor that everyone must be concerned about as it will help you in saving your energy bills. You should always go for a unit with a high Energy Efficiency Ratio (EER) as this make the unit more energy-efficient. The EER tells how many BTUs are used for each watt of power.

2. Noise Level

Before buying any portable air conditioner you must always consider this factor if the noise level is high it may lead to bad sleep so always consider this point. While portable air conditioners are not as quiet as central ACs or even window units but there are some units that are quieter than the rest with a noise level between 46-55 dBa.

3. Maintenance

This point is something special about the portable ac unit as it needs less maintenance as compared to the window ac. The only maintenance you really have to worry about is draining collected moisture. Still, in many portable air conditioners, the moisture is automatically collected.

4. Cost

Before buying any unit you must consider the cost of the unit as we all can’t buy some expensive portable ac unit so the best way is to find a unit which is less expensive and consist of almost every feature as that of an expensive unit. And to the good news, there are some portable air conditioners under 0.

5. Size of the room

The size of the room is to be considered before buying as if you need a unit for the small room then buying a high cooling capacity ac is not a good decision. Portable air conditioners are rated in British Thermal Units (BTUs) per hour. Models with higher BTU ratings offer more cooling power and can cover larger rooms.

Here is the standard chart for rooms of different sizes.

  • 8,000 BTUs will cover 200 sq. ft. (1,600 cubic feet)
  • 10,000 BTUs will cover 300 sq. ft. (2,400 cubic feet)
  • 12,000 BTUs will cover 400 sq. ft. (3,200 cubic feet)
  • 13,000 BTUs will cover 450 sq. ft. (3,600 cubic feet)
  • 14,000 BTUs will cover 500 sq. ft. (4,000 cubic feet)

6. Size of the unit

After considering all the factors the next point that you should consider is the size of the unit. Buying a big portable unit won’t be a great decision until the room is very big, but if the room is small or medium then go for a small ac. As the small one will give the same result as that of a big ac unit if you try to find one.

There are many factors that you should know irrespective of the surroundings but these are the major points that you must give importance to.
