The Best Portable Air Conditioner for a Large Room – Consumer Reviews

How Portable Air Conditioners for a Large Room Work

Portable air conditioning units move warm air from the room to provide a relaxed environment for those using the area. These units vent the warm air through an outside window or wall opening.

Most units use a standard 120-volt outlet for electrical power. Air conditioners with a 14,000 BTU rating may have to be operated on a 240-volt outlet. The unit plugs will be different from a standard 120-volt outlet plug. Make sure to read the manufacturer’s directions on what power outlet the unit operates. All types of units should be used separately from other electrical devices to avoid circuit overload.

Portable Air Conditioners Can Cool Other Rooms

Homeowners can use a portable air conditioner to cool more space when the openings are more prominent throughout the house. This means areas where the living and dining rooms have an introduction large enough to view both rooms. A den leading into the dining area is an excellent example of where a portable unit can keep both rooms cool.

Window units usually don’t operate efficiently when you place air conditioners in a room separated from other rooms by long hallways. Homeowners must consider other options when trying to cool several rooms separated by hallway space. They might need to install another portable air conditioner for a large room to keep them cool.

The Difference Between Single And Dual Hose Units

Portable units are designed differently than regular window air conditioners to keep windows free from an obstructed view. The units can be installed with the hoses attached through wall openings to provide the entire window to be free of any obstructions by homeowners should they choose that option. Most people install the hoses directly through windows to avoid extra installation work.

Air conditioners must push warm air outside through exhaust venting to cool a room properly. Air is drawn in through one vent to be exhausted through the other side of the unit. Dual hose units pull air through one hose to drain air through the other hose. The unit must remove the warm air to cool a room efficiently. The difference between the two units is that one has two hoses while the other has a single hose. A single-hose unit removes warm air through refrigerated coils outside of the house.

A single-hose unit will have to work harder to remove warm inside air due to leaks around doors and windows. This costs more money for homeowners to operate the machine unless those cracks are sealed off to prevent the air leaks from being drawn into the room. The size of the room being cooled plays a role in how much energy consumption is used by the unit.

Single-hose portable air conditioners conveniently move to other rooms without much labor. BTU output affects how efficiently the unit will operate around other heat sources, including office equipment or a small refrigerator.

Dual-hose air conditioners draw air in from the intake hose, which the coils cools to send it out into the room. The other hose removes air that exhausts through the unit to help cool it down. The dual hose unit never has to work as hard as a single one. Depending on how large the cooled room is, the dual hose unit costs more to purchase and may mean more money spent on electrical bills to operate.

How To Install A Portable Air Conditioner On Windows

Most portable air conditioner units are easy to install following the manufacturer’s directions. Standard window kits include a bracket and four to five feet long hoses. Trim the window kit to fit snugly in the window opening. Attach the hose adapters with the hoses to the equipment.

Connect the vent hose to the window kit. Make sure the window kit is sealed tight within the window opening. Plug the unit into the correct power source. Turn the air conditioner on to adjust the settings to the desired comfort level.

Other installation methods can be utilized by following the manufacturer’s directions inside the box. Some people may prefer to ventilate the unit through a wall opening or drop ceiling.

Details To Consider When Purchasing A Portable Unit

Portable air conditioners designed for use at home can cost hundreds of dollars. The square footage of the area to be cooled will play a role in what you spend on an air conditioner. Some portable units have heaters that will add to the cost of the machine.

Purchase a name-brand unit with good reviews on a solid machine that will last many years. Look for those with the energy star-rating label for efficiency. The size of the team is essential to consider. You want an air conditioner that will cool the room without operating continuously.

The higher the number of BTUs of the unit will determine how large a square foot space the machine can cool efficiently. Here are two examples of portable air conditioner sizes to cool area spaces. A room size of 300 square feet will require an air conditioning unit with 7,000 BTUs. An 18,000 BTU unit is needed to cool an area of 1,000 square feet.
