Customer Review

I received this unit within three days of ordering, so shipping was quick and reliable. Setup however, is definitely more of a hands-on process than the manual suggests. The instructions are vague, and the diagrams aren’t very clear. I had to snap off sections of the sliding window piece to get it to fit properly in my window without covering the exhaust outlet, but once I got it in, everything worked fine.

One thing to note: I had to press the reset button on the power cord before the unit would turn on —easy fix, but not mentioned in the instructions.

Once it’s up and running, though? It’s awesome. Operating the unit is simple, the controls are intuitive, and it comes with a remote (just bring your own AAA batteries). The design is sleek, and it offers cooling, fan, and dehumidifier modes.

Even just running on high fan + cooling at 61°F for 20 minutes made a noticeable drop in room temperature. I’ve been using box fans to help circulate the air throughout my space, and it’s helped tremendously during a heat wave while my central AC is down.

The unit is also quieter than most portable ACs I’ve used, which I really appreciate. My only gripe is with the drainage port—it’s located all the way at the bottom of the unit, which makes draining after using the dehumidifier mode a little awkward.

One thing to keep in mind: while it advertises as 10,000 BTU, the actual cooling capacity (DOE/SACC rating) is closer to 7,000 BTU, which is pretty typical for portable ACs due to how they’re tested. It still performs well in small to medium rooms and holds its own, especially for the price.

Buying Guide: Choosing the Best Portable Air Conditioner for 200 Square Feet

Cooling Capacity

• Look for a portable AC with a cooling capacity of at least 8,000 BTU for a 200 square foot room.
• Higher BTU ratings can cool larger spaces, but may consume more energy.
• The actual cooling capacity (DOE/SACC rating) may be lower than the advertised BTU, so consider this when making your selection.

Dehumidification

• Portable ACs with dehumidification capabilities can help reduce moisture in the air, improving comfort.
• Look for units with a dehumidification capacity of at least 2 pints per hour for a 200 square foot room.
• The dehumidification capacity should be suitable for the size of the space you’re cooling.

Noise Level

• Portable ACs can be noisy, so consider the noise level (measured in decibels) when making your purchase.
• Aim for a unit with a noise level of 60 dB or less for a more peaceful and comfortable environment.
• Some models offer a sleep mode or low-speed setting to reduce noise during nighttime use.

Portability and Installation

• Look for portable ACs with casters or wheels for easy mobility between rooms.
• Ensure the unit includes a window kit or exhaust hose for easy installation in your space.
• Consider the overall size and weight of the portable AC, as heavier models may be more difficult to move.

Additional Features

• Look for features like remote control, programmable timers, and energy-saving modes for added convenience and efficiency.
• Some models offer additional functionality, such as a built-in fan or heating capabilities, for year-round use.
• Check the warranty and customer support options provided by the manufacturer.

FAQ

1. What is the difference between ASHRAE and DOE BTU ratings?

ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) BTU ratings represent the total cooling capacity of the unit, while DOE (Department of Energy) BTU ratings represent the actual cooling capacity after accounting for factors like air circulation and energy efficiency. The DOE rating is typically lower than the ASHRAE rating, but it provides a more accurate representation of the unit’s real-world performance.

2. How do I properly size a portable air conditioner for my room?

To determine the appropriate size of a portable air conditioner for your room, you’ll need to consider the square footage of the space. As a general rule, you’ll want a unit with a cooling capacity of at least 8,000 BTU for a 200 square foot room. However, factors like ceiling height, insulation, and the number of windows can also affect the required cooling capacity, so it’s best to consult a sizing guide or speak with a professional for a more accurate recommendation.

3. How do I maintain and clean my portable air conditioner?

Proper maintenance is essential for keeping your portable air conditioner running efficiently. This includes regularly cleaning the air filter, emptying the condensate tank or connecting a drainage hose, and wiping down the exterior of the unit. Refer to the manufacturer’s instructions for specific cleaning and maintenance procedures. Neglecting these tasks can lead to decreased performance and potential damage to the unit.

4. Can I use a portable air conditioner in a room without windows?

While portable air conditioners are designed to be vented through a window, it is possible to use them in a room without windows. However, you’ll need to provide an alternative way to vent the hot air, such as by installing a wall sleeve or ducting the exhaust hose through a ceiling or wall. Keep in mind that the efficiency and performance of the portable AC may be reduced in a windowless environment.

5. How much electricity will a portable air conditioner use?

The electricity usage of a portable air conditioner will depend on factors such as the unit’s BTU rating, energy efficiency, and how often it’s used. As a general guideline, a 10,000 BTU portable AC unit can consume around 900-1,200 watts of power when running. To estimate the cost, you’ll need to consider your local electricity rates and the unit’s runtime. Energy-saving features like programmable timers and sleep modes can help reduce the overall electricity consumption.

Conclusion

Choosing the right portable air conditioner for a 200 square foot room requires careful consideration of factors like cooling capacity, dehumidification, noise level, and portability. The four models reviewed in this guide offer a range of features and performance capabilities to suit different needs and budgets. By weighing the pros and cons of each option and understanding the key buying considerations, you can make an informed decision and find the best portable AC for your small space. Remember to also factor in maintenance requirements and energy efficiency to ensure long-term comfort and cost-effectiveness.
