AC Power Consumption
Why Your Bill Increased
Electricity bill shocked you this month? It might be your AC. Understand the hidden causes and learn how to reduce costs in Mysuru & Bangalore.
The Hidden Cost of Comfort
AC power consumption issues are the #1 reason for high summer electricity bills in Karnataka. When temperatures soar above 40°C, we often blame the AC unit itself, assuming it’s faulty.
However, high bills are often caused by poor maintenance, wrong thermostat settings, or insulation gaps—not just the machine.
Common Misconceptions
Many homeowners believe that all “5 Star” ACs automatically result in low bills. This is false. Efficiency depends on usage.
Real reasons for high bills:
- Running AC at 18°C (Compressor never stops).
- Dirty filters (Motor works 2x harder).
- Oversized or Undersized AC for the room.
How to Identify a Power Issue
Before calling an electrician, check these signs.
1. Compressor Run Time
If your outdoor unit runs continuously without pausing, it’s consuming maximum power. It should cycle on and off.
2. Dirty Filters
A choked filter restricts airflow. The AC runs longer to cool the same space, directly increasing your bill.
3. Insulation Gaps
Open doors, unsealed windows, or sunlight hitting the room forces the AC to fight against external heat constantly.
Typical Power Consumption Table
Estimate your daily usage based on your AC type.
| AC Type | Capacity | Room Size | Avg. Consumption (8 hrs) | Efficiency Note |
|---|---|---|---|---|
| Window AC | 1 Ton | 100-120 sq.ft | 3 – 4 kWh (Units) | Lowest efficiency. Good for small rooms. |
| Split AC (Non-Inv) | 1.5 Ton | 150-180 sq.ft | 4 – 6 kWh (Units) | Standard consumption. High startup spikes. |
| Split AC (Inverter) | 1.5 Ton | 150-180 sq.ft | 3 – 4 kWh (Units) | Best Saver! Adjusts power to save 30%. |
| Split AC | 2 Ton | 200-250 sq.ft | 6 – 8 kWh (Units) | High consumption. For large halls. |
💡 Quick Bill Saver Tip
The “24°C Rule”: Every degree you lower below 24°C increases power consumption by ~6%.
Keep your thermostat at 24°C – 26°C and use a ceiling fan. This combo provides excellent cooling while saving drastically on electricity.
Maintenance = Savings
What To Do
- Clean filters every 2 weeks.
- Book a “Jet Service” once a year to clean coils.
- Check refrigerant levels (Low gas = High bill).
What To Avoid
- Don’t block the outdoor unit airflow.
- Don’t keep turning the AC On/Off frequently.
- Don’t ignore weird noises (it means strain).
Frequently Asked Questions
Is my AC faulty if the bill is high?
Not necessarily. First check your usage hours and thermostat settings. If those are normal, then book a service to check for dirty coils.
Does an Inverter AC really save money?
Yes. Unlike normal ACs that shut off/on (spiking power), Inverter ACs slow down the motor once the room is cool, saving up to 30% energy.
Why does an old AC use more power?
Aging compressors lose compression power, and dust accumulation over years reduces heat exchange, forcing the unit to run longer.
