 This is best for those small rented apartments where you do not have permission for modifying it.

Cons of a portable air conditioner?

Portable Air Conditioners Are Not “Easily” Portable

Portable AC units are not easily portable because they’re heavy, need to be moved on carpeting, and you may not be able to move it as much as you thought.

Noise Can Be a Factor

The main disadvantage of a portable air conditioner is the noise that it produces, which can be similar to a dishwasher or vacuum cleaner. Some people may decide that noise level is important when deciding on an AC unit.

Portable or window air conditioners are a great choice for those looking to cool down without creating too much noise.

These two options have a lower decibel rating, which is better suited for quieter environments.

Old window air conditioner will make a lot of noise though.

BTU Selection Chart by Room Size

A portable air conditioner is one that can be moved from room to room, but it does not keep the whole house cool. It must be placed in a designated spot and has a smaller BTU rating compared to central air conditioning systems.

  • 150 sq. ft. requires 5,000 Btu (British Thermal Units)
  • 250 sq. ft. requires 6,000 Btu
  • 350 sq. ft. requires 8,000 Btu
  • 450 sq. ft.: 10,000 Btu

If you are in the market for a new air conditioner, it is important to consider your room size and be aware of what Btu rating will work best. For example, if you have a 20-square foot bedroom and need an AC with 8500 BTUs then buying something that has less than 5000 would not provide adequate cooling.

Are portable air conditioners more energy efficient?

Portable ACs are not always the best choice for Indian homes. They require a high BTU rating to cool a large living space, which can increase power usage quickly.

Yes, split AC does consume more power but these cools down the room way faster that any portable AC.

For example, if a portable ac takes around 1 hour to cool down a room of 100 sq feet. A split ac or even a window AC can cool down the same room under 20 minutes.

So effective cooling capacity also goes to split ac.

So if you consider, split acs are more power efficient since the energy usages is optimum. Energy efficiency of portable units are on the lower side.

Also if you are buying a split inverter AC with high energy star and low energy consumption then it will beat any portable air conditioning systems out there.

Drainage issue

Portable AC releases water from the drainage pipe. And most of the time it will release at least 3-4 liters of water in 5-6 hours. You will need to buy a long drainage pipe to get that water out.

How to install a portable AC unit

A portable AC unit is a great option for those who live in a hot climate and especially during the summer. These units are easy to move, set up, and take down. This makes them ideal for those people looking to stay cool without having to worry about how much space they need or how long it will take to install an air conditioner. They can be used indoors as well as outdoors with their built-in wheels that make moving them around easier than ever.

 Step 1: Carefully unbox the portable AC

Step 2: Set up in a corner or with a wall behind the AC. The wall must have a window or hole in it. A ventilator would do.

Step 3: Connect the long pipe with the designated area at the back of the portable ac. This large pipe will take away hot air.

This is the exhaust and it should not leak at the ac unit and not on the place where it reaches outside. Then your AC will send heat waves via this extension to outside.

Step 4: Connect the drainage pipe.

Step 5: Connect the power plug of the portable model to 15 AMP socket or higher.

 The cooling process will start working right after you switch on power.

The power socket should be above 15amp like a fridge or AC socket. The power cord that these portable air conditioners come with have decent lenght.


What happens if you use portable AC without vent?

Can I use a portable air conditioner in a room without a window?

Yes, you can use a portable air conditioner in a room without a window. But you have to make sure that you still get an opening large enough for the ventilation/exhaust pipe to go out.
Otherwise, the portable ac will not work.

Do portable air conditioners waste a lot of electricity?

Portable air conditioners are better for Indian homes because they waste less electricity and cool the room to the same temperature. There is a risk of heat exhaustion when using portable A/C because it cannot exchange heat with anything else in the house. Window units are more power efficient than portable air conditioner due to their ability to be exchanged with hot or cold air from outside sources.
Portable air conditioners are typically more efficient at cooling a space than central units. However, they require a great deal of energy to run as well.
