10 Best Air Conditioners 2025 in the United States

The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a solid cooling capacity of 14,000 BTU ASHRAE (10,000 BTU DOE), which is suitable for rooms up to 700 sq. ft. This makes it a good fit for medium to large-sized rooms. Additionally, it has a 12,000 BTU heating capacity, allowing it to be used year-round. The unit functions as a dehumidifier and fan, adding to its versatility.

The energy efficiency ratio (SEER) of 6.2 is relatively low, indicating higher energy consumption compared to more efficient models. It's important to note that this model is not Energy Star rated, which means it might not be the most cost-effective option over time for energy savings. The noise level is 54 dB, which is moderate and may be noticeable in quieter environments but should be acceptable for most users. The air conditioner is portable, making it easy to move around as needed.

Additional features include smart connectivity with Wi-Fi, app control, and voice commands via Amazon Alexa or Google Assistant, which add convenience. The 'Follow Me' remote control is another useful feature, allowing for more precise temperature control. The product includes an easy-to-install window kit for setup. Weighing 35 pounds and having compact dimensions, it should be manageable for most people to handle. Assembly is required, which might be a minor inconvenience for some users. This BLACK+DECKER unit is a versatile and convenient option, especially for those looking for a portable and smart-controlled air conditioner with heating capabilities, despite its higher energy consumption.

The Daikin 18,000 BTU 2-Zone Mini Split is designed to provide versatile cooling and heating for two separate areas, making it ideal for homes needing personalized temperature control in different rooms without ductwork. Its cooling capacity of around 18,000 BTU (split into 9,000 and 15,000 BTU zones) is well-suited for spaces up to roughly 1,150 square feet, handling moderate-sized rooms efficiently. The system boasts a high Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER of 21), which means it uses electricity efficiently—helping reduce energy bills. Operating quietly at just 24 decibels, it won’t disturb your daily life or sleep, a definite plus for bedrooms or living areas.

This mini split uses R-32 refrigerant, which is better for the environment compared to older types. Additional perks include smartphone and voice control compatibility, a Titanium Air Purifying Filter for improved air quality, and reliable heating and cooling even in temperatures as low as 5°F or as high as 115°F. Some downsides include that it’s not Energy Star rated, which some users might expect for energy-conscious purchases, and the complexity of installation usually requires professional help, especially since it’s a multi-zone system. Also, while it includes a 15-foot installation kit, longer distances might need extra accessories.

This product suits homeowners looking for a quiet, efficient, and flexible cooling and heating solution with smart features, particularly in situations where traditional ducted systems aren’t practical.

The Goodman 3 Ton 14.5 SEER2 air conditioner paired with the multi-positional air handler offers solid cooling performance suitable for homes around 2100 square feet. With a cooling capacity of 36,000 BTUs (3 tons), it can comfortably cool medium to larger rooms. The SEER rating of 14.5 means it is reasonably energy efficient, although not the highest available on the market, so expect moderate electricity use. At 67 decibels, the noise level is about average — you’ll hear it running, but it shouldn’t be overly disruptive.

This split system uses the newer, eco-friendlier R-32 refrigerant and comes with a 10-year parts warranty when professionally installed and registered, adding peace of mind. The included air handler is versatile, supporting different installation positions (upflow, horizontal right or left), which is helpful if your home’s ductwork is tricky. However, this system only cools and does not provide heating, so if you want heat, you’ll need extra equipment like a heat pump or a separate heat kit. Also, accessories like thermostats and outdoor sensors are sold separately.

It is a dependable choice if you want straightforward, efficient cooling and are okay with adding heating solutions on your own. While not the quietest or the most energy-saving model, it delivers reliable performance backed by a good warranty.
