Best Portable ACs to Keep a Large Room Cool - 400 Square Feet and Up

From wide-open living rooms to studio apartments to offices and small storefronts, large rooms can be some of the most challenging to keep cool in the midst of summer heat waves. Fortunately, there are plenty of portable air conditioner units that are up to the task.

Family Living in Cool Comfort

livign-roomWe call the biggest room in our homes the "living room" because that's what we do there - live. It's the room where our families spend the most time together, the hub of our day-to-day activities, and the space where we welcome guests and entertain. It's important that the living room be a haven of comfort, including making sure it's cool even in the hottest weather.

Unfortunately, because these rooms tend to be so large, keeping it cool can prove difficult, even if you have central air conditioning. People and activity tend to raise the ambient temperature, so you must lower the thermostat in order to compensate. But then the rest of the house gets too cold - which is an even greater waste of money when everyone is in the living room.

A portable AC will let you add extra cooling to just the living room, without freezing out the rest of your home. You'll save money on your overall cooling costs, and still keep the room you use the most cool and comfortable. And because these units require no permanent installation, you can just roll it into storage when the hot season is over.

We recommend: For a large living room - 400 square feet and above - look for a mobile AC unit with 10,000 to 12,000 BTUs. The NewAir AC-12100E Extreme Cool portable air conditioner is easy to set up and features self-evaporative technology for nearly-maintenance-free operation. A handy remote lets you control your indoor climate from anywhere in the room.

Keeping Cool in the Kitchen

kitchenYour kitchen may not be the largest room in your house, but it's probably the hardest working. Chances are, it's coupled with a breakfast nook or dining room that makes it even more challenging to keep cool.

Then there's the matter of all that excess heat. Your oven, stove, even the refrigerator all add excess heat to the room that put an extra load on your AC. In fact, whatever the size of your kitchen, we recommend you add 4,000 BTUs to whatever the guidelines say your room requires if your portable AC is going in the kitchen.

We recommend: For a standard 10' x 10' kitchen, a portable AC with 10,000 BTUs is probably sufficient. But if you have a large kitchen with adjoining dining area, you will want to look at 12,000 or even 14,000 BTU units, like the NewAir AC-14100E, our most powerful portable air conditioner. This highly-efficient unit features commercial-quality components, and features an activated carbon filter that will help keep the air in your kitchen fresh and odor-free.

Small Living, Big Cooling

small-living-roomThe recent recession and the rising movement towards eco-friendly living has led many Americans a simpler, smaller lifestyle. Once seen as starter or transitional living spaces, studios, apartments and small homes are becoming a way of life for more and more people.

The downside to downsizing, though, is that these small spaces are rarely equipped with central cooling. That's where portable air conditioners come into play. Affordable and compact, a mobile AC lets you beat the heat in places where central or window ACs aren't available or permitted.

We recommend: Saving space is a must in small living situations, so choose a compact unit like the NewAir AC-10100H portable air conditioner and heater. Not only will this unit take up minimal amounts of floor space, but it will work for you year round - a true multi-function device that keeps you cool in the summer and warm in the winter, so there's no need to store multiple appliances when you're not using them.
