How To Choose The Best Portable Air Conditioners
Sometimes, a window or central air conditioning unit just might not get certain rooms in your home cool enough for your preferences or needs. The solution is to invest in a portable air conditioner. Portable is the key word. You can move this type of air conditioner from room to room, even taking it with you when you move. It is definitely a great choice if you have a pop-up camper for traveling or perhaps a workshop in the garage you want to keep cool when you are occupying it.
So how do you determine what the best portable air conditioners are that might suit your needs? Here are a few things to watch for:
1. Look at the power rating – Air conditioners are rated by BTUs or British Thermal Units. Basically, the higher the BTU rating, the quicker an air conditioner can cool a space. The key thing is you do not want to choose a portable unit based on the highest BTU alone as the air conditioner could freeze up, even though some have automatic shut-off switches. On the opposite side, you do not want to choose a portable air conditioner with too low of a BTU because then it cannot cool a space properly.
2. Determine square footage that needs cooling – Choosing one of the best portable air conditioners on the market means determining the square footage of space that needs cooling. The basic rule of thumb in the air conditioning industry is one square foot of space equals about 25 to 30 BTUs. Therefore, if your room is 500 square feet, the BTUs for your portable air conditioner should be around 12,500 to 15,000.
3. Consider room environment variables – When it comes to choosing one of the best portable air conditioners for you, consider the environment you are placing the unit in. If the space you plan to cool is always shaded by trees or something else, you can probably get away with a unit that has fewer BTUs than what your square footage dictates. However, if you plan to cool a sun room that gets a lot of sunlight (and therefore heat transference) you will want to choose a portable air conditioner with BTUs slightly higher than what square footage dictates.
One of the things you have to keep in mind when shopping for the best portable air conditioners for your needs is how you plan to ventilate the unit. Most of them have a flexible hose which requires venting out of a window as well as access to a grounded wall electrical receptacle. In addition, you will have different extra features to choose from such as timer controls, dehumidifier options, built-in air filters and more. Once you have the BTU requirements, square footage and environment variables nailed down, the rest boils down to the extras you are willing to pay for.
