Warranty and After-Sales Service: Ensuring Peace of Mind

When investing in an air conditioner, one should not be too lax with the warranty and after-sales service. Most such models come with a warranty of one year, but for the ones used frequently, like bedroom air conditioners, extended warranties are advisable.

Besides that, make sure that the manufacturer or retailer gives reliable after-sales support. This would save you from headaches later on, when you need some repairs or replacements.

Category Key Takeaways
Room size and BTU Match the BTU (cooling capacity) to room size for efficient cooling.

Example: 9,000-10,000 BTUs for common rooms (12-16 sqm.), 16,000-24,000 BTUs for living rooms (90-110 sqm.).
Energy efficiency Look for higher Energy Efficiency Ratio (EER) and NEA tick ratings (aim for 4-5 ticks).

More ticks mean lower energy consumption and long-term cost savings.
Types of air conditioners Portable: Suitable for non-permanent residences (e.g., dormitories).

Split-systems: Popular for homes with single/multiple rooms.
Noise levels Choose units with noise levels around 50 dB or lower for quiet operation, especially in bedrooms.
Smart features Popular features include Wi-Fi connectivity, timers, eco-mode, voice control and air purifying modes.
Installation & maintenance Hire professionals for installation. Regular maintenance (filter cleaning, annual servicing) prolongs the life of the air conditioner.
Budget considerations Balance initial cost with long-term savings through energy efficiency and special offers like climate vouchers.
Warranty & after-sales service Opt for extended warranties and reliable after-sales support to avoid issues with frequent use in places like bedrooms.
System System3+1 has a higher Installation cost, is less efficient and needs additional space, but has higher cooling capacity and is more flexible as units can be operated independently.

System4 is less flexible as all units operate together, has less cooling capacity, but has lower installation cost, is more energy-efficient, and requires less space.
