Buying Guide for 700 Sq Ft Air Conditioners
Choosing the right air conditioner for a 700 sq ft area involves consideration of several key factors to ensure efficient and cost-effective cooling:
Cooling Capacity (BTU)
Air conditioners are rated by British Thermal Units (BTU), which measure cooling power. For a 700 sq ft room, units around 14,000 BTU are typically ideal to effectively cool the space without overworking.
Type: Portable vs. Window Units
- Portable Air Conditioners: Easy to move and require minimal installation. Suitable for renters or spaces without suitable windows.
- Window Air Conditioners: Often more efficient and quieter but require installation in a window or wall opening.
Energy Efficiency
Select models with energy-saving features such as inverter technology or ENERGY STAR ratings to reduce electricity costs and environmental impact.
Noise Levels
Look for units with quiet operation, especially if you plan to use the air conditioner in bedrooms or offices. Noise levels below 50 decibels are considered relatively quiet.
Smart Controls and Convenience Features
Wi-Fi enabled units or those compatible with voice assistants like Alexa or Google provide flexible control through apps or voice commands. Additional features like remote control, timers, auto restart, sleep mode, and child lock increase usability.
Dehumidification and Fan Modes
Many units offer combined air cooling, dehumidifying, and fan functions, useful for controlling humidity and enhancing comfort in varying weather conditions.
Maintenance and Installation
Consider how easily filters can be cleaned or replaced and whether the unit has features like auto-evaporation for drainage. Window units require mounting, whereas portable units only need window venting kits.
Taking these factors into account will help you choose an air conditioner that best fits your room size, cooling needs, and lifestyle preferences.
