8 Best Dual Exhaust Portable Air Conditioners 2025 in the United States

The Whynter Portable Air Conditioner 14,000 BTU is ideal for cooling large rooms up to 500 square feet. It boasts a high cooling capacity and a built-in dehumidifier with a 71-pint/day capacity, which is great for maintaining indoor air quality. The noise level is relatively low at 51 dB, making it suitable for bedrooms and other quiet spaces. The unit is portable, with dimensions of 19”D x 16”W x 35.5”H, and includes a window kit for easier installation. However, it is on the larger side, which might not be ideal for very small spaces.

The Energy Efficiency Ratio (EER) is 7.69, which is on the lower end and means it may not be the most energy-efficient option available. Additionally, it does not have an Energy Star rating. The unit offers three operational modes: cooling, dehumidifying, and fan, with full thermostatic control ranging from 61°F to 89°F, providing versatile use. Maintenance is straightforward with an activated carbon air filter and a washable pre-filter, although regular cleaning will be needed to ensure optimal performance.

This product is best suited for users looking for a powerful, multi-functional air conditioner capable of cooling and dehumidifying large areas while maintaining a relatively quiet operation.

The Whynter Inverter Portable Air Conditioner is a powerful and efficient cooling solution for rooms up to 600 square feet. With a cooling capacity of 14,000 BTU, it is well-suited for larger rooms. It boasts an Energy Efficiency Ratio (EER) of 12.3, which is decent, though not the highest in its class. The noise level is relatively low at 42.5 dB, making it a quiet option for home use. Its portability is enhanced by its compact size (16.75”D x 19.5”W x 32.5”H) and the included window installation kit. The dual-hose design helps prevent heat leakage, ensuring more efficient cooling.

Additionally, the unit features a dehumidification function that can handle up to 87 pints per day, which is a great feature for humid environments. Smart control options via the NetHome Plus app and compatibility with Alexa and Google Home add convenience, allowing you to control the unit remotely. Maintenance is straightforward with a washable air filter, which saves on replacement costs.

However, the unit is not Energy Star certified, which might be a consideration for those seeking maximum energy efficiency. The product is recognized for its performance by Forbes, which named it the 'Best Portable Air Conditioner' for 2024. This Whynter model is an excellent choice for those needing a robust, quiet, and smart-controlled portable air conditioner, especially in larger spaces.

The Gasbye Dual Hose Portable Air Conditioner is a noteworthy option for those needing efficient cooling solutions for spaces up to 500 square feet. Its cooling capacity is strong, offering 14,000 BTU (ASHRAE) and 10,500 BTU (SACC), making it suitable for medium to large rooms. A highlight of this model is its energy-saving feature, boasting a 13.6 SEER rating, which is quite impressive in the portable AC market, potentially reducing energy bills.

One of its standout features is the dual-hose system, which helps in quicker cooling and maintaining indoor pressure, an advantage over single-hose models. The noise level is remarkably low at 45 dB, thanks to the advanced inverter technology, making it a good choice for bedrooms or offices where quiet operation is essential. Portability is another strength, with its relatively compact size and included window vent kits and hose assemblies. Weighing 65 pounds, it is manageable for most users to move around as needed. The backlit remote control is a thoughtful addition for easy adjustments at night.

This unit not only cools but also functions as a fan and dehumidifier, adding versatility to its use. Though it generally doesn’t require manual drainage, in very high humidity areas, drainage might become necessary, but the unit is designed for easier handling of this process. However, at 1290 watts, it may still impact electricity usage, and the 3-year warranty, while a positive, is standard for many in this category. Additionally, the black color might not suit all decor preferences. Despite these minor drawbacks, the Gasbye AC offers a strong, efficient, and quiet cooling solution for a variety of settings.
