Best Portable Air Conditioner for the Home in 2019 [Buyer’s Guide]

Sharing is caring!

People tend to rely on air conditioning units to keep their home, and offices cool especially when the temperature starts to rise. If you do not have access to a central air unit or you just moved into your new home and are thinking of installing a centralized air conditioning in your home to get you through hot summer days, be prepared to shell out a minimum of $6,000 up to a whopping $15,000.

Yes, it would cost you that much because pricing depends on the complexity and size of the job. Not to mention other repairs and added pieces of equipment to support the installation such as ducts, exhaust, or filters.

The best possible solution is to install a non-centralized air conditioning unit. Aside from less work involved, it will also be a lot cheaper. The next problem is choosing between window-mounted and portable air conditioning unit. Most people only prefer to have an air conditioner installed in parts of the house where there is not enough natural ventilation and where people gather most of the time.

Difference Between Window-Mounted Air Conditioner Vs. Portable Air Conditioner

Both wall-mounted and portable air conditioner are effective in creating a more comfortable room temperature, especially during summer. Both are also more energy efficient and less expensive to operate when used only when needed compared to centralized air conditioning unit. However, each has an advantage and disadvantages. Here are some of them.

Window-Mounted Air Conditioner

  • If you have a smaller living space and you want to avoid clutter, a window-mounted air conditioner is a better option for you.
  • Window type AC is quite harder to install and it usually just fits a standard sized window.
  • A window-mounted air conditioner is more energy efficient than a portable air conditioner.
  • It is less expensive than a portable AC unit.
  • When it comes to noise level, window type AC is kind of louder than portable ones.
  • There is no water to dispose of because the moisture is vented internally.

Portable Air Conditioner

  • The best thing about portable air conditioner is mobility. It is independent, and you can move it around the house where you need it the most. The exhaust hoses are easier to install than a window-mounted air conditioner.
  • A portable air conditioner unit is a little more expensive than a window-mounted AC unit of similar cooling capacity. The larger the unit, the more expensive it will be.
  • You won’t find a portable air conditioner unit with EER star rating for energy efficiency because there are no specific federal regulations to determine the energy efficiency of portable AC units.
  • You will have to empty the collected water in the dedicated water tray or tank regularly.
  • The noise level of portable AC units vary. Some are as quiet as a fan while some are a little louder.

Things to Consider When Buying a Portable Air Conditioner

If you have already decided to go for a portable air conditioner, these are some of the things you should consider before you purchase one.

1. Size

The cooling power of portable AC units is measured in BTU or British Thermal Units per hour. A higher BTU means higher cooling power, more considerable room coverage, and a bigger portable AC unit. Although the size determines the cooling power of the unit, you must not solely depend on the scale because you have a big room that needs cooling.

Some environmental factors may affect the effectivity of the cooling process even when you are using a large portable AC unit to cool the room adequately. Factors such as poor room insulation and a room with several appliances that produce heat should also be considered. In these cases, you might have to buy an AC unit that has a higher BTU.

2. Placement

The hot air a portable AC produces must be expelled out of their hoses as it cools the room. Choosing which room you want to place the unit is entirely up to you, but it is best that you set it near a window for proper ventilation.

3. Maintenance

Unlike window-mounted air conditioners, you must drain the water collected manually to empty the tank or tray. You can attach a hose to drain the water out or take the unit outside for removing and cleaning.

However, some high-tech portable AC models feature a self-evaporative design which automatically removes collected moisture, so users do not have to empty the tank frequently.

4. Noise Level

Any machine that regulates airflow should be expected to create some level of noise. If this is a significant concern for you, you should first compare the decibel (dB) levels of the models before buying one.

5. Energy Efficiency

Energy efficiency affects both the environment and your pocket. If you are aiming for one that will not do much harm to the environment and will not cause your monthly bill to skyrocket, always look at the EER or Energy Efficiency Ratio that tells you the amount of BTUs used per power watt. Energy efficient units usually have a higher EER.

Frequently Asked Questions

How can I calculate the appropriate BTU level that I need to cool a specific room?

This is an estimated BTU calculation for a room that has a standard 8-foot ceiling. Keep in mind that even with the right BTU size, other factors may affect the effectivity of the cooling process.

150 sq. ft = approx. 7,500 BTU
200 sq. ft = approx. 9,000 BTU
300 sq. ft = approx. 10,000 BTU
400 sq. ft = approx. 12,000 BTU
450 sq. ft = approx. 13,000 BTU
500 sq. ft = approx. 14,000 BTU

How do single-hose design portable air conditioners differ from double-hose design units?

Portable air conditioners that have a single-hose design take air from the room, process and cool it, and expel most of it back into the room. Those that feature a double-hose design work by taking warm air from outside the house through the hose and eject it to the second hose to cool it and discharge it into the room

If my window has a screen, do I have to remove it when I use the window kit? What about a sliding glass window?

You can opt to remove the screen of your window especially if the exhaust hose is short and cannot be extended, but most portable air conditioners can work on traditional vertical sash windows or double-hung windows.

If you have a sliding glass window, it could be a little bit complicated. You might have to use two window kits and make some improvisions to make it work.
