Basic Guide to Purchasing an Air Con

🛒 Before Buying an Aircon

1. Which aircon is best for home use?

Split units are the most popular for home use due to their energy efficiency, quiet operation, and sleek design. Portable and window units are cheaper but less effective for larger rooms.

2. What size aircon do I need for my room?

To cool a room efficiently, you need the right BTU (cooling power). A 12–20m² room typically needs a 9,000 BTU unit. Larger areas need more power. An expert can help size your unit correctly.

3. What is the difference between inverter and non-inverter air conditioners?

Inverter aircons regulate power, using less electricity and running more quietly. Non-inverter units turn on/off frequently, consuming more energy. Inverters cost more upfront but save more long-term.

💡 Usage & Efficiency

4. How much electricity does an aircon use?

This depends on the unit size and how long it runs. A 9,000 BTU inverter might use around 0.8–1.2 kWh per hour. Using energy-efficient models and smart settings can lower your bill.

5. Is it cheaper to use a fan or an aircon?

Fans use far less electricity but don’t cool the air—just move it. Aircons cool effectively but cost more. For mild days, fans are better; for real cooling, aircons win.

6. What is the best temperature to set the aircon for comfort and savings?

Set your aircon to 22–24°C in summer. Each degree lower increases power use. In winter, 18–20°C is ideal for heating.

🛠️ Maintenance & Troubleshooting

7. How often should I service my air conditioner?

Service your aircon at least once a year. If used daily, twice a year is better. Regular maintenance keeps it efficient and extends its life.

8. Why is my aircon not cooling properly?

It could be dirty filters, a gas leak, or compressor issues. If it’s not cooling as it should, a professional should inspect it.

9. Can I install an aircon myself?

Installing an aircon requires proper tools and refrigerant handling—best left to certified installers. DIY installation may void the warranty and pose safety risks.

10. How long does a home aircon last?

Most quality units last 10–15 years with proper maintenance. Regular servicing helps avoid breakdowns and keeps it running efficiently.
