Buyer’s Guide: How to Choose the Best Air Conditioner for Your House
Room Size and Cooling Capacity
The first step is determining the square footage of the room you want to cool. Window ACs and portable units are rated by BTU, indicating their cooling power. Generally, 5,000 BTU is suitable for small rooms up to 150 sq ft, while 14,000 BTU units can efficiently cool up to 700 sq ft or larger spaces. Choosing the correct BTU ensures energy efficiency and optimal cooling.

Type of Air Conditioner: Window vs Portable
Window air conditioners are installed in a window frame and tend to have a lower upfront cost and more efficient cooling for small to medium rooms. Portable air conditioners offer flexibility to move the unit between rooms and often include additional features like dehumidification, but might be less efficient and usually require venting through a window.
Energy Efficiency and Operating Cost
Look for ACs with a high Combined Energy Efficiency Ratio (CEER) or Energy Efficiency Ratio (EER). Higher ratings mean the unit uses less electricity for the cooling delivered, saving money on energy bills. Some brands offer eco-friendly refrigerants like R410A or R32 which have less environmental impact.
Noise Level
If you intend to use the unit in bedrooms or office spaces, consider models with noise levels below 50 decibels (dB) for minimal disturbance. Some units include special noise-reduction technologies or sleep modes to further lower sound.
Control Features and Smart Connectivity
Basic mechanical controls may suffice for simple needs, but many modern AC units offer digital controls, remote controls, timers, and even Wi-Fi connectivity with app and voice assistant support. These features enhance convenience and allow customized temperature schedules.
Installation and Maintenance
Window units usually require some installation but often come with kits for easier setup. Portable ACs need venting kits but are generally simpler to relocate. Reusable or washable filters reduce maintenance effort, but check how frequently filters or parts need replacement.
Additional Features
Functions like 3-in-1 cooling (air conditioner, fan, and dehumidifier), auto-restart after power failures, and air direction control add value. Consider your climate and specific needs before selecting these extras.
