Aren’t the sultry summer months treacherous? The summer season brings along the harsh sun glaring into your eyes, and unpleasant sweat trickles down your spine. Whether you like it or not, summer does find its way back every year.

How about giving summer a miss this year with an excellent portable air conditioner that is best for a large room?  As per the national news report, summer is going to be hotter than usual this year.

In such a situation, it would be wise to buy an air conditioner, which is portable yet keeps a pleasant temperature even in a large room.  Also, a portable air conditioner effectively circulates fresh air in a large room that is not ventilated.

Oh!  Don’t you wish you could take your air conditioner everywhere you go? The best portable air conditioner for large rooms can make your wish come true.  You can stroll it into the basement, or enjoy the cool breeze when you sip your smoothie on the patio.

What’s more?  You can maneuver the portable air conditioner in a large room, such as a basement or rooms that do not have any outward-facing window.  A portable air conditioner is far more effective than an air conditioner unit that sticks to one place. 

Since the wall-mounted air conditioner unit is large, we assume it will cool a large room quickly.  However, we are mistaken.  The powerful cooling system of a portable air conditioner evenly cools the air in a room’s size 300 to 400 sq ft or more much faster than any other type of air conditioner. 

The best part about a portable air conditioner is that it is eco-friendly.  So you do not feel guilty about leaving carbon footprints.   Additionally, it helps you save energy.  Since the cooling is effective and fast, you will not have to worry about your electricity bills.  The dual filters also purify the air in a large room, leaving it crisp.

What Should You Look For Before Buying The Best Portable Air Conditioner For Large Rooms?

If you cannot resist the temptation of buying a portable air conditioner for your large room, you should watch against impulsive shopping. Here is a short and sweet buyers’ guide on what you should look for in the best portable air conditioner.  

Silent Motor

Most of the air conditioners are loud and noisy.  However, the trendy portable air conditioner is as quiet as a mouse.   It allows you to cuddle in your bed for a catnap without any disturbing noise.  While purchasing an air conditioner, go for the one that has a silent motor.

Ease Of Set-Up

Let’s face it! You may not be an expert at installing an air conditioner. The makers of portable air conditioners probably know that and save you from the headache of setting up the air conditioner. Buyers can choose an air conditioner, which is easy to install.

Do you get an inflated electricity bill at the end of every month?  It is a fact that air conditioners consume a lot of power. It would be best to switch over to a more economical portable air conditioner that not only keeps your large room cool but provides peace of mind. 

A portable air conditioner with 12000 BTU consumes less power and provides effective cooling at the same time.  You do not need a costly central cooling system when a portable air conditioner does the trick without pinching your pocket. An average American apartment’s room’s size is not more than 300 to 400 sq ft. An air conditioner with 600 to 14000 BTU cooling capacity may be enough to cool your room.

How To Find The Perfect Portable Air Conditioner For Your Rooms?

Though there are many features that you need to consider while purchasing the portable AC, there are two important aspects that make it to the top of the list. These are:

British Thermal Units (BTUs)

This feature is the parameter of measuring the conditioner’s cooling capacity. You choose your BTU’s as per the size of your room.

Seasonally Adjusted Cooling Capacity (SACC) 

This is a new parameter of rating which gets measured in BTU per hour. This is weighted average as per different test ratings.
