How to Reduce AC Costs During Summer
As temperatures rise across the UAE during summer, air conditioning becomes essential for maintaining a comfortable indoor environment. However, keeping indoor spaces cool throughout the season can significantly increase electricity consumption and utility bills. Whether you live in an apartment or a villa, adopting energy-efficient cooling practices can help reduce AC costs during the summer.
Smart Ways to Reduce AC Costs During Summer
From thermostat settings and insulation improvements to routine maintenance, several practical measures can lower AC usage and improve system performance. Here are some of the useful ways to save money on air conditioning.
Set Thermostat on Energy-Efficient Temperature

One of the easiest ways to reduce AC cost during the summer is to avoid setting temperatures lower than necessary. DEWA recommends maintaining indoor temperatures at 24°C or slightly higher for an ideal balance between comfort and energy efficiency. Lower temperatures force the system to run continuously, increasing electricity consumption. Moreover, increasing the set temperature by just one degree can reduce AC consumption by up to 5%.
You can use auto mode instead of keeping the fan running continuously. This allows the compressor to cycle only when needed.
Additional thermostat practices include:
- Increase the temperature slightly
- Avoid sudden temperature drops
- Maintain consistent cooling instead of frequent adjustments
Clean or Replace AC Filters Frequently
Dirty or clogged filters not only increase electricity consumption but can also affect indoor air quality and overall comfort. When they become clogged, airflow reduces and the system works harder to cool indoor spaces. DEWA recommends cleaning AC filters at least once every month during summer for better performance and lower energy use.
Regular AC filter maintenance can:
- Improve cooling performance
- Reduce energy consumption
- Enhance indoor air quality
- Extend system lifespan
For central AC systems, periodic duct inspections can also improve efficiency.
Block Heat Before It Enters Your Home

Your AC cost is not only affected by thermostat settings, but the heat entering your home also plays a major role. Minimising indoor heat gain helps reduce dependency on air conditioning. You can consider these approaches to block the heat from entering your home:
- Closing curtains during peak sunlight hours. You can also use blackout curtains, thermal curtains and UV-blocking blinds.
- Installing reflective window films can reduce solar heat entering living spaces while allowing natural light indoors.
Seal Air Leaks Around Doors and Windows
Cool air escaping from small gaps can significantly increase cooling costs. Inspect window edges, balcony doors and AC vents joints to prevent cool air from escaping from the gaps.
Apply weather stripping and caulking around doors and windows to minimise air leakage and maintain indoor cooling. Proper sealing helps keep conditioned air inside while preventing hot outdoor air from entering your home, reducing the overall load on your AC system.
Use Ceiling Fans Alongside Air Conditioning
Fans consume much less electricity than AC systems and can improve comfort without lowering the thermostat. A ceiling or standing fan circulates cool air more effectively, helping rooms feel cooler even at slightly higher temperatures. This means you may comfortably increase your thermostat setting while maintaining indoor comfort.
Upgrade Older AC Units
If your air conditioner is more than 10 years old, replacing it may lead to long-term savings. Consider replacing ageing systems with energy-efficient air conditioners that carry a 4-star or 5-star rating from the Emirates Authority for Standardization and Metrology (ESMA). Choosing a higher-rated unit can improve cooling efficiency and may reduce cooling energy consumption by up to 25%.
Install a Smart Thermostat

Smart thermostats are becoming increasingly popular in UAE homes because they automate cooling schedules. Some of the pros of installing a smart thermostat include:
- Remote temperature control
- Scheduled operation
- Energy monitoring
- Reduced cooling during unoccupied hours
It also helps in optimising HVAC usage and reducing electricity waste, especially during summer.
Monitor Electricity Consumption
Tracking utility usage helps identify patterns and areas for improvement. You can consider:
- Comparing monthly bills
- Monitoring peak usage periods
- Reviewing thermostat schedules
- Identifying appliances contributing to consumption
Small changes made consistently often produce meaningful savings over the summer season.
Upgrade to Energy-Efficient Cooling Systems
Older air conditioning units generally consume more electricity than modern energy-efficient systems. When buying an AC in the UAE, consider:
- High energy-efficiency ratings
- Inverter technology
- Smart cooling controls
- Proper sizing for the property
An oversized or undersized system can increase long-term operating costs.
FAQs
What is the ideal thermostat setting to save energy in summer?
The recommended thermostat setting during summer is 24°C, as it balances comfort and energy efficiency.
Does regular AC maintenance help lower electricity bills?
Yes, regular AC maintenance helps reduce high electricity bills by ensuring the system operates efficiently and does not overwork.
How often should AC filters be cleaned or replaced?
AC filters should generally be cleaned at least once a month during periods of frequent use, especially in summer. Replacement frequency depends on the filter type and manufacturer recommendations, but regular inspection is important.
Learning how to reduce AC costs during summer is essential for managing household expenses in the UAE’s hot climate. Whether you live in an apartment or villa, proactive AC management not only lowers electricity bills but also supports longer system life and improved indoor air quality.
