The Hidden Cost of Common AC Mistakes

Are you shocked by your monthly electricity bill during summer? You're not alone. Many Indian households see their electricity costs double or triple when using air conditioners, often reaching ₹8,000-₹15,000 per month.

The good news? Most of these high bills are caused by simple, avoidable mistakes. By fixing these common errors, you can reduce your AC electricity consumption by 30-40% without compromising on comfort.

Quick Start: Estimate your monthly AC bill using our AC Bill Calculator to see your current costs before implementing these fixes.

1

Setting Temperature Too Low (18°C-20°C)

⚠️ Impact: Increases electricity consumption by 20-25%

Many users set their AC to 18°C or 20°C thinking it will cool faster. This is the biggest mistake! Your AC works harder to maintain extremely low temperatures, consuming significantly more power.

✅ Smart Fix:

  • • Set temperature to 24-26°C for optimal comfort and efficiency
  • • Use ceiling fans to circulate air and feel cooler at higher temperatures
  • • Save ₹1,200-₹1,500 per month with this simple change
2

Not Cleaning or Replacing Filters

⚠️ Impact: Increases power consumption by 15-20%

Dirty filters block airflow, forcing your AC to work harder to circulate air. This simple maintenance task is often overlooked but has a huge impact on electricity bills.

✅ Smart Fix:

  • • Clean filters every 2-3 weeks during heavy usage
  • • Replace filters every 3-6 months depending on usage
  • • Save ₹800-₹1,000 per month with clean filters
3

Poor Insulation and Air Leaks

⚠️ Impact: Increases electricity consumption by 25-30%

Leaving doors and windows open, or having gaps around them, lets cool air escape and hot air enter. Your AC has to work continuously to maintain the desired temperature.

✅ Smart Fix:

  • • Seal gaps around doors and windows with weather strips
  • • Keep doors and windows closed when AC is running
  • • Use thick curtains to block sunlight and heat
  • • Save ₹1,500-₹2,000 per month with proper insulation
4

Using Old, Low Star-Rated ACs

⚠️ Impact: 1-star ACs consume 40-50% more power than 5-star models

If you're using a 1-star or 2-star AC, especially one that's more than 5 years old, it's likely consuming much more electricity than necessary. Modern 5-star ACs are significantly more efficient.

✅ Smart Fix:

5

Skipping Regular AC Servicing

⚠️ Impact: Increases power consumption by 15-25%

Dirty coils, low refrigerant levels, and worn components make your AC work harder. Regular servicing ensures optimal performance and prevents costly breakdowns.

✅ Smart Fix:

  • • Schedule professional servicing twice a year
  • • Clean outdoor unit coils monthly
  • • Check refrigerant levels annually
  • • Save ₹1,000-₹1,500 per month with regular maintenance
6

Running AC When Not Needed

⚠️ Impact: Unnecessary 6-8 hours of daily consumption

Many users run their AC all day or forget to turn it off when leaving rooms. This wastes enormous amounts of electricity, especially during moderate weather or when rooms are empty.

✅ Smart Fix:

  • • Use timer functions to automatically turn off AC
  • • Install smart thermostats or programmable timers
  • • Turn off AC when room is empty for more than 30 minutes
  • • Save ₹2,000-₹3,000 per month with smart scheduling
7

Not Using Ceiling Fans with AC

⚠️ Impact: Missing 20-25% potential savings

Ceiling fans help circulate cool air more effectively, allowing you to set your AC to a higher temperature while maintaining the same comfort level. This combination is highly energy-efficient.

✅ Smart Fix:

  • • Run ceiling fans with AC to improve air circulation
  • • Set AC to 26°C with fan instead of 22°C without fan
  • • Position fans to distribute cool air evenly
  • • Save ₹800-₹1,200 per month with this simple combination
