Cooling Capacity (BTU)
Select an AC unit with the appropriate BTU rating for your room size. Generally, 9,000-12,000 BTU units work well for rooms up to 500 square feet, while larger spaces may require 14,000 BTU or more. Oversized units can cause inefficient energy use and short cycling.

Wall-mounted air conditioners require through-the-wall installation, which might need professional assistance. Ensure your wall and home setup can accommodate the unit’s size and ventilation requirements. Some units can double as window air conditioners, but confirm compatibility before purchase.
Power Supply and Voltage
220V units are common for larger capacity ACs and require appropriate electrical wiring. Confirm your home’s power supply matches the unit specifications to avoid compatibility issues or electrical hazards.
Energy Efficiency
Look for energy-efficient models with inverter technology, high EER (Energy Efficiency Ratio), or use of modern refrigerants like R-32 to save on electricity costs and reduce environmental impact.
Additional Features
- Heating Capability: Useful for year-round climate control, especially in cooler regions.
- Smart Controls: Remote operation, thermostats, timers, and smart home integration enhance convenience.
- Air Quality Enhancements: Features like air ionizers and washable filters improve indoor air quality.
- Modes and Fan Speeds: Multiple modes (cool, heat, dry, fan) and adjustable fan speeds allow customized comfort.
Maintenance
Choose units with easily accessible and washable filters, and consider defrost functions for heating models to prevent ice buildup. Regular maintenance ensures optimal performance and longevity.
