Buying Guide: Portable air conditioners and dehumidifiers

Room Size and Capacity

Consider the square footage of your space when choosing a portable air conditioner or dehumidifier. Match the unit’s capacity (BTU for ACs, pints per day for dehumidifiers) to your room size for optimal performance.

Energy Efficiency

Look for Energy Star certified models to ensure lower energy consumption. Higher EER (Energy Efficiency Ratio) ratings for air conditioners and lower wattage for dehumidifiers indicate better efficiency.

Noise Level

Check the decibel (dB) rating, especially if using the unit in bedrooms or quiet spaces. Lower dB ratings mean quieter operation, with some models offering special sleep modes for reduced noise.

Additional Features

Consider features like remote controls, programmable timers, and multiple operating modes. For dehumidifiers, auto shut-off and continuous drain options can add convenience. Some portable ACs offer WiFi connectivity for smart home integration.

Portability and Installation

Evaluate the unit’s weight and dimensions if you plan to move it between rooms. Look for models with easy-to-install window kits for portable ACs, and consider the water tank capacity and emptying process for dehumidifiers.

FAQs: Portable air conditioners and dehumidifiers

How do I choose the right size portable air conditioner for my room?

Measure your room’s square footage and choose a unit with appropriate BTU capacity. Generally, you need about 20 BTU per square foot of living space.

Can a portable air conditioner cool multiple rooms?

Portable ACs are designed to cool single rooms. For multiple rooms, you’d need a unit with higher BTU or consider separate units for each space.

How often should I empty my dehumidifier’s water tank?

It depends on humidity levels and tank size. Most units have auto shut-off when full, but checking daily is a good practice. Some models offer continuous drain options for convenience.

Do portable air conditioners need to be vented?

Yes, portable ACs need to be vented through a window or wall to expel hot air. Most come with window kits for easy installation.

Can I use a dehumidifier and air conditioner together?

Yes, using both can be beneficial in humid climates. The dehumidifier can help remove excess moisture, allowing the AC to cool more efficiently.

How do I maintain my portable air conditioner or dehumidifier?

Regularly clean or replace filters, empty water tanks (for dehumidifiers), and ensure proper ventilation. Follow the manufacturer’s maintenance guidelines for optimal performance.
