What is the Best Temperature for AC?

Air conditioning has become an inseparable part of life in India, especially during the long, hot summer months. Families, students, and working professionals rely heavily on their AC units to stay comfortable indoors. But while most people spend hours comparing AC brands, models, and features, very few consider one of the most important aspects of usage—the best temperature setting for the AC.

If you are looking for expert advice or servicing, the Carrier AC Service Center in Hyderabad strongly recommends setting your AC at the right temperature to maximize comfort, energy savings, and long-term durability. But the real question is: what is the best temperature for your AC, and why does it matter so much?

In this detailed blog, we’ll explore recommended AC temperature ranges, the effects of different settings on your electricity bills, health, and environment, and practical tips to achieve the perfect cooling balance at home and office.

Why Does AC Temperature Matter?

The temperature setting on your AC isn’t just about personal comfort—it has a direct impact on your health, energy consumption, and even the life span of your cooling system.

• Too Low: Setting your AC to 18°C may seem like the fastest way to beat the heat, but it forces the compressor to run continuously, consumes excessive electricity, and reduces efficiency over time.

• Too High: On the other hand, keeping the setting above 28°C in peak summers won’t provide enough cooling, leaving the room uncomfortable.

Striking the right balance between comfort and energy efficiency is the key to enjoying your AC without unnecessary costs or breakdowns.

Recommended Best AC Temperature – Advice from Carrier AC Service Center in Hyderabad

According to the Bureau of Energy Efficiency (BEE) and various energy experts, the ideal AC temperature for Indian households and offices is between 24°C and 26°C.

Why 24°C to 26°C is Best:

1. Energy Efficiency – Every degree you lower below 24°C increases your electricity consumption by 6–8%.

2. Health Benefits – Very low temperatures cause throat irritation, respiratory issues, and dry skin.

3. Environmental Impact – Balanced AC usage reduces greenhouse gas emissions.

4. Durability of AC – Constantly running the AC at 18°C or 20°C puts extreme load on the compressor, leading to frequent repairs.

This range offers the perfect balance of cooling, comfort, and cost savings.

Best AC Temperature in Different Scenarios

1. Sleeping Hours

The best AC temperature while sleeping is 25°C to 26°C. Your body naturally cools down while you sleep, so this range avoids extreme cold and ensures uninterrupted rest.

2. Summers in India

During peak summer months in cities like Delhi, Mumbai, or Hyderabad, setting your AC to 24°C ensures quick cooling without skyrocketing electricity bills.

3. Winters & Heating Mode

If you use an AC with heating, the recommended setting is 20°C to 22°C, creating a warm and cozy indoor environment.

4. Offices & Commercial Spaces

Workplaces should keep ACs at 24°C to 25°C, maintaining comfort while avoiding extra operational costs.

Real-Life Example: Electricity Bill Savings

Let’s assume your monthly electricity bill is ₹4,000 with your AC set at 22°C. If you adjust it to 24°C, you can save up to 15%, bringing your bill down to around ₹3,400. Over a 6-month summer season, that’s nearly ₹3,600 saved annually—just by increasing your AC temperature by 2°C.

How AC Temperature Affects Energy Consumption

• 22°C vs 24°C – Consumes ~15% more power.

• 24°C vs 27°C – Can save 20–25% on bills.

• Constant Low Setting (18°C/20°C) – Leads to compressor strain, expensive repairs, and wasted energy.

The Carrier AC Service Center in Hyderabad has observed that users who maintain their AC at 24°C to 26°C enjoy significantly lower bills and fewer repair calls.

Tips to Maintain the Best Temperature

1. Use Ceiling Fans Together – Fans help circulate air, letting you increase AC temperature by 1–2°C without losing comfort.

2. Close Curtains & Windows – Prevent heat from entering and reduce load on the AC.

3. Regular Maintenance – Clean filters and book servicing with trusted providers like Dial Service Centre.

4. Use Eco or Sleep Mode – Automatically balances comfort and efficiency.

5. Seal Air Leaks – Prevent cool air from escaping through gaps around doors or windows.

6. Use a Thermostat or Smart Plug – Helps maintain consistent indoor temperatures.

Health Considerations of AC Temperature

Improper AC settings can cause several health problems:

• Respiratory Issues – Very cold rooms can cause cough, throat irritation, or even sinus problems.

• Dry Skin and Eyes – Low temperatures remove moisture from the air.

• Muscle Stiffness – Staying in excessively cold rooms may tighten muscles and joints.

• Weakened Immunity – Constant exposure to extreme cold may make you more prone to colds and flu.

By setting your AC between 24°C and 26°C, you can maintain comfort while protecting your health.

Balancing Comfort, Cost & Longevity

It’s tempting to lower your AC to 18°C after coming in from the heat, but doing so doesn’t cool your room faster. It only increases energy use and reduces your AC’s lifespan. A balanced approach—setting AC at 24°C, combining with fans, and ensuring maintenance—ensures both comfort and savings.

The Role of AC Technology

Modern ACs come with advanced features that help users maintain the best cooling experience:

• Inverter Technology – Adjusts compressor speed based on room temperature.

• Dual Sensors – Maintain stable and efficient cooling.

• Smart Controls – Mobile apps let you adjust AC temperature remotely.

• Air Purification Features – Improve indoor air quality.

Brands like Carrier, Daikin, and LG continue to innovate in this space. If you’re curious about which brand dominates the market, check out our related blog: Which is the No 1 AC brand in India?

Common Mistakes to Avoid with AC Temperature

• Setting AC to 18°C initially – Does not cool faster, only strains compressor.

• Skipping Maintenance – Dirty filters reduce cooling efficiency.

• Not Using Eco or Sleep Modes – Wastes electricity.

• Running AC Nonstop – Short breaks help the compressor work better.

• Ignoring Room Insulation – Poor insulation leads to wasted energy.

Final Thoughts

The best AC temperature depends on your comfort needs, electricity costs, and system efficiency. In India, the recommended range of 24°C to 26°C is ideal for households and workplaces.

Instead of chasing extreme cold, focus on energy-efficient usage and proper maintenance. If you encounter cooling issues or need expert servicing, the Carrier AC Service Center in Hyderabad is always ready to help.
