How to Save Electricity Bill in Summer with AC in Pakistan: An Expert’s Guide

As the Pakistani summer hits full stride, so does the dread of opening that monthly electricity bill. Running an air conditioner feels essential for comfort, but it can consume up to 50-60% of your total electricity bill during these hot months.

But what if we told you you don’t have to choose between comfort and cost? With over 15 years in the home appliance industry, we’ve learned the secrets to maximizing AC efficiency.

Here are 10 practical, expert-recommended tips to significantly reduce your AC’s power consumption and keep your electricity bill under control this summer.

1. Set the Thermostat to the Optimal Temperature (The Golden Rule)

The Tip: Stop blasting your AC at 16°C. Instead, set your thermostat to 24-26°C.

The Why: This is the most effective step. Your AC compressor works hardest to achieve the largest temperature difference between the outside and inside. A setting of 24°C is comfortably cool and drastically reduces the compressor’s workload compared to a lower setting. Every degree you raise the thermostat can save 3-5% on your cooling costs.

2. Embrace the “Dry” or “Dehumidify” Mode

The Tip: On humid days (common in many parts of Pakistan), use the “Dry” mode instead of the standard “Cool” mode.

The Why: A major part of the summer’s discomfort comes from humidity. The “Dry” mode runs the compressor at shorter intervals to primarily remove moisture from the air, which makes you feel cooler without drastically lowering the temperature. It consumes significantly less power than the full cooling mode.The Tip: On humid days (common in many parts of Pakistan), use the “Dry” mode instead of the standard “Cool” mode.

3. Seal the Leaks: Don’t Let Cool Air Escape

The Tip: Check all windows and doors for gaps. Use weather stripping or simple draft stoppers to seal them.

The Why: Your AC is fighting a losing battle if cool air is escaping and hot air is seeping in. A well-sealed room allows the AC to reach the desired temperature faster and shuts off sooner, saving energy.

4. Clean Those Filters! (Your AC’s Lungs)

The Tip: Clean your AC’s air filters every two weeks during peak summer.

The Why: Clogged, dusty filters restrict airflow, forcing the AC unit to work much harder to circulate cool air. This simple 5-minute maintenance task can improve efficiency by 5-15%. It’s the easiest win on this list

5. Use Ceiling Fans in Conjunction with Your AC

The Tip: Turn on your ceiling fan while the AC is running.

The Why: A ceiling fan creates a wind-chill effect, making you feel 3-4 degrees cooler. This allows you to set your AC thermostat at a higher temperature (like 26°C) while maintaining the same level of comfort. Fans consume a fraction of the electricity an AC uses.

6. Smart Timing: Use a Timer or Programmable Thermostat

The Tip: Use your AC’s timer function to turn it off 30-45 minutes before you wake up or leave the room.

The Why: The room will stay cool for a while after the AC turns off. This prevents the unit from running unnecessarily when no one is there to benefit from it. For a bigger investment, a smart thermostat can learn your schedule and optimize cooling automatically.

7. Shield Your Room from the Sun

The Tip: Keep curtains or blinds closed during the day, especially on windows facing the sun.

The Why: Direct sunlight dramatically heats up a room. Blocking it out reduces the “heat load,” meaning your AC doesn’t have to work as hard to counteract the sun’s effect.

8. Ensure Regular Professional Servicing

The Tip: Get your AC serviced by a professional at least once a year, ideally before summer.

The Why: A technician will clean the internal coils, check refrigerant gas levels, and ensure all components are working efficiently. A poorly maintained AC unit can consume 20-30% more electricity.

9. Upgrade to an Inverter AC

The Tip: If your AC is old (over 8-10 years), consider replacing it with a new 5-star Inverter AC.

The Why: This is a long-term solution. Inverter technology allows the compressor to run at variable speeds instead of just turning on and off. It maintains temperature consistently and uses far less power. While the initial cost is higher, the electricity savings can be substantial, paying for itself over time.

10. Choose the Right Capacity for Your Room

The Tip: Ensure your AC has the correct BTU (British Thermal Unit) rating for your room size.

The Why: An undersized AC will run non-stop trying to cool the room, wasting energy. An oversized AC will cool too quickly without properly dehumidifying the air, leading to a clammy feel and short cycling, which is inefficient. Use online BTU calculators to find the perfect match.

FAQ: Your AC Electricity Saving Questions Answered

Q1: What is the best AC mode to save electricity?
A: For general cooling, “Cool” mode at 24-26°C. For humid but not extremely hot days, “Dry” mode is the most efficient.

Q2: Does turning the AC on and off cost more?
A: Yes, frequently. The compressor uses a surge of power to start up. It’s more efficient to leave it on at a higher temperature when you’re home than to turn it off and on repeatedly.

Q3: Which brand of AC is most energy-efficient in Pakistan?
A: Brands like Gree, Dawlance, and Haier offer excellent 5-star inverter models. Efficiency can vary by model, so always check the energy rating label. We’ve compared them in our Gree vs Dawlance AC article.

Final Verdict

Saving on your electricity bill isn’t about sweating through the summer; it’s about using your AC smarter. By combining these tips—especially setting the thermostat higher, using “Dry” mode, and regular maintenance—you can enjoy a cool home without the shock of an unaffordable bill.
