What to Check Before Buying

The portable air conditioners are not very expensive and surely are good items to buy to have a more comfortable house during several hot months during the year.

There are a few things to check before buying, the price is surely important, but also check the following:

Humidity Control

Several small units does not have a built-in dehumidifier. If the air is hot and humid this can be a problem, the air will be cool but not comfortable. The units I have selected all come with a built in dehumidifier

Auto Restart

If you work and you are outside your home all day, consider a unit with an auto restart feature. If there is a thunderstorm and a power failure the portable conditioner will restart immediately as soon as the power come back, else you will arrive at home to find a powered off unit and a hothouse.

Enough Power for Your Room

If you have an open space apartment you do not need to buy separate units to cool every room, a powerful one may be enough to cool all the apartment.

How to size a Portable Air Conditioner?

Calculating a portable AC unit’s BTU requirements is simple. First determine the room’s square footage by multiplying its length by width, then look to the chart below to get a general idea of how many BTUs you need.

The Importance of BTUs

If you purchase a portable air conditioner with a higher BTU rating than needed, the unit will cycle off too quickly and not properly remove humidity from the air.  Moreover, a portable AC with an insufficient number of BTUs will not adequately cool a room. That’s why experts often advise consumers to pay close attention to a room’s floor plan in order to figure out how many BTUs space requires.

Where to use your Portable Air Conditioner?

Portable air conditioners are functional in a variety of living conditions. Dorm rooms, apartments, condominiums, or even a house can benefit from a portable air conditioner. Many places don’t offer air conditioning of any kind. If that’s the case, then a portable air conditioner is a great option.

How Does These Units Work

Portable air conditioners are different from the traditional ones. They are self contained units that can cool only a single room, they sit on the floor and they usually come with wheels to move them easily from a room to another.

All portable units need to exhaust hot air. To do this there is a hose supplied with the unit that direct the hot air out of a window. Do not position your unit in the middle of the room, but always near a window to allow the hot air to get easily outside the room you are cooling.

The new portable air conditioners also dehumidify the air and they are now able to evaporate moisture through the air exhaust hose, so there is no more need to empty the accumulated water as it was in the past.

The very basic small units are designed for small rooms of less than 300 Sq. Ft., while there are more powerful ones that are able to cool a surface of about 500 Sq.Ft., so with one unit you can cool a quite large living area.

Before deciding which one to buy, remember that also the number of people living in the room generate heat. So buy an unit a little more powerful than the total surface of your room would suggest to be sure you it will be powerful enough to cool the room even when you have guests.

Tips for a Cooler House

Even if you have an air conditioning apply these simple measures to keep your house cooler and save on electricity bill.

  • Keep your windows and shutters closed during the day, do not let in the hot and humid air.
  • Do not use separate dehumidifier and air conditioner together. The Dehumidifier will cause the air conditioner to work more and this will cost you more. As already said get a unit with built in dehumidifier.
  • Buy and install blinds to your windows, they can reduce the solar heat up to 40%.
  • Install bamboo screens outside your windows, this help to reduce the sun heat up to 70%.
