10 Best Portable Air Conditioner Heater Combo 2026 in the United States

The Amazon Basics Portable AC with Heat Pump is a versatile device designed to cool or heat rooms up to 550 square feet, making it ideal for moderate-sized spaces. With a cooling capacity of 13,000 BTU (ASHARE) and 10,000 BTU (SACC), it offers substantial power for temperature control. The unit's portability is a standout feature, with rolling caster wheels and ergonomic side handles facilitating easy movement.

Installation is user-friendly, thanks to the included venting kit and adaptable window fit, accommodating various window types. The dual hose design enhances efficiency by drawing in outside air and using it for cooling, which generally results in better performance and faster cooling/heating. The control interface is practical, featuring an LED display and a multifunction remote, allowing users to customize their comfort with three speeds, three cooling settings, and an automatic timer.

Additionally, the dehumidification function can be beneficial in humid climates, further enhancing indoor comfort. This product is fitting for those needing an easily portable, dual-purpose climate control solution with flexible installation options and straightforward operation.

The LG 23,000 BTU Window Air Conditioner with Heat is a versatile unit designed to cool or heat rooms up to 1400 square feet, making it suitable for medium to large spaces such as living rooms, dens, bedrooms, or offices. With a cooling power of 23,000 BTUs, it ensures substantial cooling performance. The unit operates at a relatively low noise level of 50-51dB, which is quiet enough for a peaceful environment during work or sleep.

The unit is relatively heavy, weighing 145 pounds, which might affect its portability despite being a window unit. It comes with an installation kit to help with setup. The energy efficiency ratio (EER) of 11.3 is decent, although the unit is not Energy Star certified, indicating it may not be the most energy-efficient option on the market. The device features multiple fan speeds for both cooling and heating, providing flexibility to adjust the comfort levels as needed.

The auto-restart function is helpful for resuming operation after a power outage, and the remote control adds convenience. The unit also includes a dehumidification function, although the capacity of 3.3 pints may not be sufficient for very humid environments. Maintenance is manageable with a filter light reminder to alert you when it's time for cleaning. This LG unit is a robust performer with a variety of useful features, ideal for those looking to efficiently manage their indoor climate throughout the year, but its weight and lack of top-tier energy efficiency are considerations to keep in mind.

The SereneLife 14000 BTU Portable Inverter Air Conditioner and Heater is designed to cool and heat spaces up to around 650 square feet, making it a good choice for bedrooms, offices, or living rooms. Its inverter technology helps it cool faster and use about 40% less energy than many standard portable units, which can save on electricity bills. With a noise level of around 53 dB, it’s reasonably quiet—not completely silent, but unlikely to disturb daily activities or sleep. It features smart Wi-Fi control and remote control, allowing easy temperature adjustments without getting up. The unit offers four modes: cooling, heating, dehumidifying, and fan, so it's useful year-round.

Portability is enhanced by smooth casters and a compact design, although it weighs over 50 pounds, so it’s better for moving between rooms rather than frequent transport. Installation is straightforward with the included window kit, but it uses a single hose exhaust, which may be less efficient than dual hose models in some situations. Maintenance is user-friendly thanks to a washable air filter, helping maintain air quality and extend the unit’s life.

While the noise rating might be higher than some inverter ACs that advertise ultra-quiet operation, this model balances power and quietness well for its size and BTU. Its energy efficiency, multi-mode functionality, and smart controls make it a solid option if you want a versatile, space-saving portable climate solution, though those looking for ultra-quiet or dual hose setups might want to explore other options.
