Introduction
Choosing the right air conditioner (AC) is essential for maintaining a comfortable indoor environment, especially in regions with extreme weather like Saudi Arabia. With numerous options available — from window units to split systems and inverter ACs — selecting the best AC requires careful consideration of room size, energy efficiency, cooling capacity, and budget. This comprehensive guide will help you understand the different types of air conditioners, how to calculate the right size, and which brands and features to consider to ensure maximum comfort and efficiency.

Why Choosing the Right AC Matters
An improperly sized or inefficient AC can lead to poor cooling, high energy bills, and frequent maintenance issues. The right AC will not only cool your room effectively but also save on energy costs and provide long-term durability.
Types of Air Conditioners
Understanding the various types of ACs is crucial for making an informed decision. Here are the four primary types of air conditioners:
1. Split AC
- Made up of two parts: an indoor unit (evaporator) and an outdoor unit (compressor).
- Provides quiet performance and effective cooling.
- Perfect for use in bedrooms and living rooms.
2. Window AC
- A single unit installed in a window or wall opening.
- Easy to install and cost-effective.
- Best for small to medium-sized rooms.
3. Portable AC
- A movable unit with an exhaust hose.
- Suitable for temporary cooling or spaces where installation isn’t possible.
- Less efficient compared to split and window ACs.
4. Central AC
- Uses a system of ducts to cool the entire house efficiently.
- Requires professional installation.
- Best for large homes or commercial spaces.
Inverter AC vs. Non-Inverter AC
✅ Inverter AC
- Adjusts compressor speed based on room temperature, improving efficiency.
- Saves up to 30%–50% more energy than non-inverter ACs.
- Provides consistent cooling without frequent start-stop cycles.
❌ Non-Inverter AC
- Operates at a fixed speed.
- Consumes more energy due to frequent start-stop operation.
- Less efficient and noisier.
How to Choose the Right AC Capacity
What is BTU?
BTU (British Thermal Unit) indicates how much cooling power an AC has. Higher BTU means more cooling power.
| Room Size (sq. ft) | Required Capacity (BTU) | Recommended AC Ton |
|---|---|---|
| Up to 150 | 5,000 – 6,000 | 0.5 – 0.75 ton |
| 150 – 250 | 6,000 – 8,000 | 0.75 – 1 ton |
| 250 – 350 | 8,000 – 10,000 | 1 – 1.25 ton |
| 350 – 500 | 10,000 – 12,000 | 1.25 – 1.5 ton |
| 500 – 750 | 12,000 – 15,000 | 1.5 – 2 ton |
| 750 – 1,000 | 15,000 – 18,000 | 2 – 2.5 ton |
Example: A 12×12 ft room (144 sq. ft) would require around 0.8 to 1 ton of AC.
How to Calculate Room Size for AC
Use this formula to calculate the required tonnage:
Room Area (sq. ft)×25÷12,000=Required AC Ton\text{Room Area (sq. ft)} \times 25 \div 12,000 = \text{Required AC Ton}
Example:
- Room size = 12 × 12 = 144 sq. ft
- 144×25÷12,000=0.3144 \times 25 \div 12,000 = 0.3 tons (round up to 1 ton for better efficiency).
Key Things to Keep in Mind When Choosing an AC
1. Room Size and Ceiling Height
- Larger rooms need higher capacity ACs.
- High ceilings increase the cooling load.
2. Climate and Location
- In hot and humid areas like Saudi Arabia, opt for higher BTU ratings and inverter models.
3. Energy Efficiency
- Look for ACs with a high SEER (Seasonal Energy Efficiency Ratio) rating.
- Inverter models are generally more energy-efficient.
4. Noise Level
- Split ACs are quieter than window or portable units.
- Ideal noise level: Below 50 decibels (dB).
5. Additional Features
- Dehumidification: Reduces extra moisture in the air for a more comfortable environment.
- Smart Controls: Wi-Fi connectivity, remote access, and scheduling.
- Air Filters: HEPA filters help enhance air quality by trapping dust and allergens.
- Sleep Mode: Reduces noise and adjusts temperature automatically. Read More: SEO Services in Ontario

FAQs About Choosing an AC
1. Is a 1.5-ton AC enough for a 12×12 room?
A 1.5-ton AC is overpowered for a 12×12 room. A 1-ton AC would be more suitable.
2. Which AC type is most energy-efficient?
Inverter split ACs are highly energy-efficient because they adjust the compressor speed based on cooling needs.
3. What is the best AC brand?
Daikin, LG, and Mitsubishi are considered the most reliable and efficient.
4. How much power does a 1.5-ton AC consume per hour?
A 1.5-ton inverter AC usually consumes between 1.2 to 1.5 kWh of electricity per hour.
5. Which AC is better, Daikin or LG?
Daikin offers better long-term durability, while LG provides more smart features.
Conclusion
Selecting the right AC depends on knowing your room size, cooling capacity, energy efficiency, and key features. For a small to medium room, a 1-ton inverter split AC from Daikin or LG is ideal. For larger spaces, a central or high-capacity split system will provide efficient cooling. Focus on energy-efficient models with smart features to enhance comfort while reducing power consumption. By keeping these factors in mind, you can enjoy consistent cooling and reduced energy costs throughout the year.
