📋 Table of Contents
1What cooling capacity (BTU) should I look for in a split air conditioner?
For a standard room of 10-15 square meters, aim for 8,000-12,000 BTU. Larger rooms or spaces with high heat gain (e.g., kitchens, sunrooms) may need 14,000-18,000 BTU. Overpowering a small space can lead to humidity issues and higher energy bills.
2What’s the difference between inverter and non-inverter models?
Inverter models adjust compressor speed to maintain consistent temperature, saving energy and reducing wear. Non-inverter models cycle on and off, causing temperature fluctuations and higher electricity use, especially in hot climates or with frequent use.
3How important is the energy efficiency rating (SEER or EER)?
Look for a minimum SEER of 14 or EER of 10 for standard efficiency. Higher ratings (16+ SEER) reduce long-term costs, though they may cost more upfront. Energy-efficient models also tend to be quieter and more reliable over time.
4What size indoor and outdoor units should I choose?
The indoor unit should match the outdoor unit’s capacity, typically in a 1:1 ratio. For example, a 1.5-ton indoor unit pairs with a 1.5-ton outdoor unit. Mismatched units can cause inefficiency, overheating, or system failure.
5Are smart features worth the extra cost?
Smart features like Wi-Fi control, remote monitoring, and auto-restart can improve convenience and energy savings. They’re most valuable for tech-savvy users or those who want to manage temperature from a phone. Basic models may lack these but are more budget-friendly for occasional use.
