The air conditioner seems very good and will do what we need. The window connection plate is definitely a bit of a challenge. You have to be ready to be inventive and handy at least with my window to get it installed properly but I understand that you can't foresee every situation.

What about ventilation?

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.

Are there certain types of windows that are not suitable for PACs?

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.

Can I leave the window screen in during installation?

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

How do I know how many BTUs are required to cool my space?

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

What do I need to know about PAC energy consumption?

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.

What added benefits does my portable air conditioner offer?

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.

Do portable air conditioners consume a lot of energy?

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.

Are PACs only beneficial during the summer season?

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.

Should I remove the insect screen after installing the window kit?

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

How can I improve the performance of my portable air conditioner?

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.

My portable air conditioner is not cooling down my space. Why?

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?

Honeywell Portable Air Conditioner - Stay cool. Stay dry.

The HL series is a new addition to the contemporary, stylish and powerful Honeywell Portable Air Conditioners. The HL10CESWW Honeywell Portable Air Conditioner combines 3-in-1 technology into one sleek body, cooling and dehumidifying areas up to 350 sq. ft.
