How to save on air conditioning bills?

Air conditioning doesn't have to be expensive to operate. Research shows that average families can save 20-30% on energy consumption if they use air conditioning correctly. In this article, we'll show practical tips you can implement today to reduce your electricity bills.

Energy-saving tips

1. Set temperature to 23-24°C instead of 18-20°C

This is the most important rule. Every degree Celsius less uses 10% more energy. If you normally keep temperature at 21°C, change to 24°C – you'll save 30 PLN per month (on a 300 PLN bill). Research shows that 23-24°C is ideal for sleep and work – you won't feel uncomfortable. In Szczecin, where summer temperatures reach 25-28°C, 24°C is an ideal target temperature.

2. Close doors between rooms

If air conditioning runs in the living room while other rooms are open, cold air escapes. Close doors to rooms you're not using. Cool only the spaces where you actually stay. You'll save 15-20% of energy.

3. Close blinds and curtains during the day

Sun penetrates through windows, heating your apartment. Before turning on air conditioning, close blinds or curtains – block solar radiation. Indoor temperature won't rise as quickly. You'll save 20-25% of energy, especially in south-facing rooms.

4. Clean filters monthly

It's simple but important. Dirty filters force the air conditioner to work harder – it uses more energy and cools poorly. Remove the filter from the indoor unit, dust it off (vacuum or compressed air) and reinstall. Clean filter = 10% energy savings.

5. Service once a year

Well-maintained air conditioning uses less power. Spring inspection extends equipment life and reduces energy consumption. A technician cleans heat exchangers, checks sealing, and refills refrigerant. You'll save 15-30% of energy through service.

6. Choose A+ or higher energy class equipment

If you're planning new air conditioning, check the energy label. A or A+ class air conditioners use 30-40% less energy than class B or C. Modern Daikin, Toshiba, Fujitsu with InverterRAY technology guarantees low bills. The additional 2,000-3,000 PLN for better equipment pays back in 2-3 seasons.

7. Use timer function

Every modern air conditioner has a timer. Instead of running it for 8 hours, turn it on 30-45 minutes before you arrive home. The room will cool down and temperature stabilizes. You'll save 40-50% of energy compared to all-day operation.

8. Use Eco mode

Most air conditioners have Eco mode – it reduces compressor and fan speed to operate at lower power. Eco mode is ideal for sleeping – quiet, economical and cool enough.

9. Don't place outdoor unit in direct sun

If the outdoor unit works in sunlight, it must work harder. If possible, install it in shade or add a solar screen. You'll save 5-10% of energy.

10. Combine air conditioning with heat recovery ventilation

This is the best long-term solution. Heat recovery provides fresh air without heat loss, so air conditioning works less. Together you save 25-35% of energy annually.

Practical savings examples

Scenario 1 – 60 m² apartment without changes:

Air conditioning runs for 4 months (May-September), consuming 500 kWh. Cost: 500 kWh × 0.60 PLN/kWh = 300 PLN.

Scenario 2 – Same apartment with changes (24°C, timer, blinds):

Energy consumption drops to 350 kWh (30% savings). Cost: 350 kWh × 0.60 PLN/kWh = 210 PLN. Savings: 90 PLN per season.

Scenario 3 – New A+ class air conditioning (20% less energy) + implementing tips:

Energy consumption: 300 kWh. Cost: 300 kWh × 0.60 PLN/kWh = 180 PLN. Savings: 120 PLN per season. Over 5 years, you save 600 PLN in electricity alone, plus reduced maintenance costs.

Summary

The cheapest air conditioning is already installed. Proper use can save 20-30% of energy every season. Combining multiple tips – right temperature, timer, maintenance, blinds – gives even better results. Invest in modern equipment and proper habits, and your air conditioning becomes profitable.
