Well, if you have a limited budget to install a central AC unit or if you are looking for a unit to complement your existing central AC unit; then there are two popular choices that are portable air conditioners and window units! Both are relatively easier for the installation without needing to hire a professional technician, I mean you can install both by yourself so thus you will get free cost for the installation. But which is the best one of both? Portable A/C units are quite & portable enough (as well as like the name implies) to carry around from one room to others. Most of them are usually also designed with wheels on the bottom to support their superior portable feature.
Both are also available in a wide range of sizes to accommodate different square feet sizes of different rooms. They are usually rated by BTUs or Watts! Moreover, they also must be vented properly in order to ensure the machine will be able to work optimally and efficiently. Both are great solution for anyone who is looking for a cooling device to complement his or her existing central air conditioning system. The big difference point of both is the installation procedure, particularly which the window units usually must be installed into the right size of the window, and on other hand the window size consideration is not important for portable air conditioning units or we call them as air conditioners that don’t need a window for the installation (therefore there are many people say that portable air conditioners are better than window units because they are real portable cooling device that much more practical either for the installation or re-installation).
Like mentioned before, moveable air conditioners are available in a wide range of Watts output (more than 18000 Watts to the smallest sizes (around 1800 Watts)). Furthermore, there are also available the ones that are also equipped with electric resistance heating element so thus also support for a portable heater during winter.
If you care to your local environment then it is better to purchase one that has good efficiency feature, such higher rating of SEER and Energy Star Approval. These features are not only crucial for the environment but also important to make sure you will use a unit that can keep working efficiently in long term that eventually also so helpful to save your money for each month (low energy bill). Moreover, choosing one that has good efficiency rating features is also great idea to make your decision to use it for complementing your existing central A/C will be much better.
And in line with technological developments, there are now also available the ones that adopt R410a refrigerant non-Freon technology. As well we know that conventional air conditioners use R-22 refrigerant technology that can bring bad effect to the depletion of Ozone. Other alternative option is portable evaporative air cooler. This type is also much friendlier to the environment. But unfortunately, evaporative air coolers or also familiar called as swamp coolers are not recommended for any areas, because their performance is closely related to the humidity and ambient temperature! Therefore, you should discuss to a local HVAC contractor first before deciding to use & install a swamp cooler system. Ask to them about is it qualified to use a swamp cooler in your local area or not!
Based on the hose system, portable air conditioners are divided into two major categories that are air to air and mono-block! The second models are usually relatively cheaper than the first models, because they use a tray to collect the condensed water. The tray must be kept not-overflow by user otherwise the unit will shut down automatically. This mechanism is the reason why mono-block models can be categorized into a cooling unit that cannot work continuously without assistance. On other hand, air to air models usually use re-evaporate technology to evaporate the condensed water automatically so thus they don’t need a tray and can work continuously without manual assistance.
As well as we know, one big downside of portable air conditioning units is their unfriendly loud noise. Yes, they are a real portable cooling unit but they cannot work quietly as well as like central air conditioners. Therefore, it is so important to consider the decibel value of the unit that you are purchasing. The other idea is by choosing a mini-split portable air conditioner! This type is much quieter than other regular portable A/C models! It has condenser and compressor that are housed into an outdoor unit and this design is the key of its quietness performance. In addition, for more practically installation, ductless mini-split portable air conditioners are welcome idea; moreover they don’t need ductwork to cool the air.
In addition, there are some reviews say portable air conditioning cannot work as powerful as window units! Therefore, once again, it is so important to calculate the size of portable unit correctly. Make sure the unit is sized correctly to the larger size of your room in order to ensure it will work properly and powerful enough!
