How to Reduce AC Costs and Save on UAE Electricity Bills

Living in the UAE means braving some of the hottest temperatures in the world. While air conditioning is a lifesaver, it can also be a major contributor to high electricity bills during long summer months. The good news? You can stay cool and conserve energy without sacrificing comfort. With a few simple changes and smart tools, you can significantly cut down your energy expenses.

Here’s how you can manage AC use efficiently and keep those electricity bills in check.

Use a Smart Thermostat for Better Control

Investing in a smart thermostat or an air conditioning (AC) controller can revolutionize the way you use your cooling system. Smart thermostats allow you to control your HVAC system remotely via mobile apps. This means you can adjust or schedule your cooling settings even when you’re not home.

According to Dinesh Ramachandran, Technical & HSE Manager at Rentokil Boecker, remote control of cooling systems during peak hours helps ensure optimal energy consumption. Features like scheduling and automation also allow for smarter usage, helping to keep cooling costs under control while maintaining comfort.

Pro Tip:

Set your thermostat to automatically reduce cooling when no one is at home and bring it back to a comfortable level before you return. This small adjustment can make a noticeable difference in energy consumption.

Set the Ideal Temperature for Efficiency

Comfort is important, but so is efficiency. The Dubai Electricity and Water Authority (DEWA) recommends setting your AC thermostat to 24°C. This temperature balances comfort with energy savings. For every degree you lower the temperature, your energy consumption increases by approximately 5%.

If you’re stepping out for a few hours, turn off your AC or set the temperature to around 27°C to avoid unnecessary energy wastage.

Bonus Feature:

Many modern AC units come with a “SLEEP” mode that gradually adjusts the temperature throughout the night for comfort and energy efficiency. For example, it may raise the settings by 1°C every hour until it reaches 24–25°C. This feature can help you wake up feeling refreshed, knowing you’ve conserved energy while you slept.

Block Heat with Shading Solutions

Keeping the heat out starts with simple shading strategies. During the hottest parts of the day, close your curtains, blinds, or shades. This prevents the sun from warming up your interior spaces and reduces reliance on your AC.

“Shading devices such as blackout curtains or solar screens are excellent at minimizing sunlight entering your home,” says Ramachandran. These tools can make a significant difference in reducing indoor heat gain, ultimately helping your AC system operate more efficiently.

No-cost Tip:

If you’re looking for a quick and budget-friendly option, opt for reflective window films or light-colored curtains. They deflect sunlight and allow you to maintain a cooler indoor temperature.

Upgrade Ageing AC Units

If your AC unit is over 10 years old, it might be time to consider an upgrade. Older systems are less energy-efficient, and new models are often designed to meet higher standards of performance and efficiency. Units with a 4- or 5-star energy efficiency rating can reduce your cooling energy consumption by up to 25%, according to DEWA.

Why It’s Worth It:

While the upfront cost of a new AC system might seem steep, the long-term energy savings and improved cooling performance make it a wise investment.

Don’t Switch Off Completely When on Holiday

When leaving for an extended vacation, it might seem like a good idea to turn off the AC entirely to save money. However, experts warn against doing this in the UAE’s humid climate. Turning off the AC completely can lead to issues like mold, mildew, and even structural damage due to excess moisture.

Instead, set your AC to a moderate temperature while you’re away. Use a programmable thermostat or smart AC controller to maintain consistent indoor humidity levels. This also allows you to monitor and adjust your settings remotely for peace of mind.

Quick Tip for Vacationers:

Set your smart thermostat to 27°C while you’re away to save energy while safeguarding your home against excess humidity-related damage.

Additional Ways to Save on Energy Costs

While managing AC usage is critical, there are other actions you can take to keep your electricity bills in check:

• Seal Your Windows and Doors: Ensure that there are no gaps or leaks in your windows and doors, which can allow cool air to escape.
• Switch to Energy-efficient Appliances: Apart from upgrading your AC, consider replacing old household appliances with energy-efficient alternatives.
• Regular AC Maintenance: Clean or replace your AC filters every month during the summer or as recommended by your unit manufacturer. Clogged filters reduce airflow and force your unit to work harder, consuming more energy.

Stay Cool, Save Smart

Managing energy costs during summer in the UAE is all about combining smart technology with practical habits. Implement these tips to minimize your electricity expenses while staying cool and comfortable. Not only will you save money, but you’ll also reduce your environmental impact by conserving energy.
