Customer Reviews For The Honeywell MN12CES Portable Air Conditioner, 12,000 BTU Cooling (Black-Silver)

Portable ACs use either a single hose or dual hose design. In cooling mode, single hose PACs remove hot air from the room, and then expel the hot air out the one hose. In cooling mode, dual hose PACs bring in air from outside through one hose, and expels warm air outside through the second hose. In both cases cold air in cooling mode flows through the unit's vents into the room.

Casement windows are quite unique in design and functionality so PACs do not have window kits that can completely cover the gap for these types of specialty windows.

The screen may not interfere with installation, but for better releasing of hot air out the window, it is better to remove the screen.

A BTU (British Thermal Unit) is a standard unit of energy that measures the amount of heat per hour an air conditioner removes from a room. The larger the room, the higher the BTU requirement. Below, are some general guidelines. However other factors – such as the number of open doorways, a south-facing window with continuous sunlight, or a room with high occupancy – can require a unit with a higher BTU rating than the average guidelines.

Room Size in sq. ft. BTU

• 350      8,000
• 450      10,000
• 550      12,000
• 700      14,000
• 1,000   18,000

AC units demand a lot of energy, so should not be paired on the same electrical outlet with other similar high-consumption devices. Always plug the unit into an available electrical outlet. Never use an extension cord to power your portable air conditioner.

Portable Air Conditioners are easy-to-use handy devices that can be moved around from one place to the other with ease. A portable air conditioner will naturally reduce humidity indoors, which is perfect for hot, humid summer weather. An additional fan mode can help circulate air throughout the room even when you have turned off air conditioning cooling.

Air conditioners, including portable air conditioners, are complex machines and heavy power users. However, energy savings can lie in your usage of the technology. Choosing to cool down a single room with a portable air conditioner rather than switching on whole-house central air could result in significant cost savings.

Depending on the model, portable air conditioners can also convert into dehumidifiers, extracting humidity without the cooling feature. This can be useful in the colder, wetter seasons if your space is prone to mold or mildew. Some Honeywell models are also equipped with a heating element, transforming the unit into a secondary heating source for winter.

The air flow will work better without the obstruction of the insect screen. We suggest removing the screen.

Several factors can affect the performance of your portable air conditioner. Foremost is whether your unit's BTU is suitable for your space. An inadequate BTU will not result in cooling. Other factors can affect performance, too: rooms with large open doorways or within open-plan spaces; rooms with poor insulation or high ceilings; south-facing rooms with copious direct sunlight. If any of these are the case, see if you can tighten up the insulation and overall boundaries, and add light-colored window coverings. Another factor is room occupancy. Crowded rooms will be hotter and require a more powerful unit to cool down.

Run through this troubleshooting checklist:

• Check your unit's BTU with your square footage and ceiling height.
• Determine if your room has many openings – doorways or windows.
• Determine if your walls and flooring are poorly insulated.
• Does your room receive a lot of strong, direct sunlight?
• Is your room often crowded?
