Summer 2025 is shaping up to be a scorcher, meaning your air conditioner is about to become your best friend. But staying cool doesn’t have to come with sky-high energy bills. With just a few smart adjustments, you can enjoy a comfortable home without overworking your system or draining your wallet. Whether you're dealing with record heat or just trying to lower your energy footprint, efficient AC usage during summer is key. Read on for simple, effective tips to keep your cool while keeping costs - and waste - at a minimum.
Choose the Right Thermostat Settings for Summer 2025
One of the simplest yet most impactful changes you can make is adjusting your thermostat settings wisely.
- Set your thermostat to 78°F (25-26°C) when at home. This is the optimal balance between comfort and energy savings.
- Raise the temperature by 7–10°F when you're away for more than two hours. This can reduce cooling costs by up to 10% annually.
- Invest in a smart thermostat that adjusts automatically based on your preferences and presence. These devices help reduce energy consumption by adapting in real time, just one of the many benefits of programmable thermostats, which allow for convenient scheduling and improved energy efficiency without compromising comfort.
Seal and Insulate Your Home Properly
A major source of energy inefficiency comes from cool air escaping and hot air seeping in. Proper sealing and insulation can significantly boost your AC’s efficiency.
- Seal leaks around windows, doors, vents, and ductwork using caulk or weather stripping.
- Insulate attics, walls, and floors to prevent heat from entering your home and straining your air conditioner.
- Install thermal curtains or shades to block out sunlight during peak heat hours.
Keep Up with Routine AC Maintenance
Your AC unit’s performance is only as good as its upkeep. Regular maintenance ensures a longer lifespan and lower energy bills.
- Replace or clean air filters monthly, especially during high-use months. Clogged filters force the system to work harder.
- Schedule annual professional tune-ups to check for refrigerant levels, clean coils, inspect components, and calibrate the thermostat.
- Clear the outdoor unit of debris, such as leaves or grass clippings, which can block airflow and reduce efficiency.
Use Ceiling Fans to Support Your AC
Ceiling fans don’t cool air, but they make you feel cooler by enhancing air circulation, allowing you to raise your thermostat setting without sacrificing comfort.
- Run ceiling fans counterclockwise in summer to push cool air downward.
- Turn off fans when not in the room to avoid unnecessary electricity use.
Upgrade to an Energy-Efficient Air Conditioning System
If your AC unit is more than 10-15 years old, it may be time to consider a modern, energy-efficient replacement.
- Look for ENERGY STAR® certified systems, which use up to 15% less energy than standard models.
- Choose the right size for your home. An oversized unit will cycle on and off too frequently, while an undersized one will struggle to keep up.
- Consider inverter or variable-speed compressors that adjust their power use to match cooling demand, minimizing energy waste.
Utilize Programmable and Zoned Cooling Systems
Zoning your cooling system gives you precise control over temperatures in different parts of the house.
- Create zones by using separate thermostats for each area or by installing dampers in the ductwork.
- Program each zone based on occupancy and time of day to avoid cooling empty rooms.
- Use room-specific AC units, such as mini-splits, for rooms that require different cooling levels.
Limit Heat-Generating Activities During Peak Hours
Daily habits significantly impact your home’s internal temperature. Limiting heat-generating appliances and behaviors helps reduce strain on your AC.
- Avoid using ovens, stoves, and dryers between 12 PM and 6 PM, the hottest parts of the day.
- Opt for grilling outdoors or microwave cooking instead.
- Run dishwashers and laundry machines at night, when temperatures are cooler and energy demand is lower.
Block Out Solar Heat Gain with Smart Shading Solutions
Solar heat gain can increase indoor temperatures by several degrees. Strategic shading helps keep your space cooler naturally.
- Install window films or solar screens that reflect sunlight.
- Plant deciduous trees around your home to provide natural shade.
- Use awnings or pergolas to shade patios and south-facing windows.
Dehumidify to Feel Cooler Without Lowering the Thermostat
Humidity makes warm air feel even hotter. Dehumidification helps you stay comfortable at higher thermostat settings.
- Use a dehumidifier in damp rooms, such as basements or bathrooms.
- Ensure your AC system includes a humidity control feature or integrate one into your HVAC system.
- Keep interior doors open to allow for better air and moisture circulation.
Monitor and Reduce Phantom Loads from Electronics
Many electronics continue to generate heat and draw power even when not in use, adding to your cooling burden.
- Unplug devices when not in use or use a smart power strip.
- Switch off idle electronics, such as gaming consoles or computer monitors.
- Relocate electronics away from thermostats, which can misread room temperature due to nearby heat sources.
Embrace Passive Cooling Techniques for Added Relief
Passive cooling techniques can significantly ease your reliance on air conditioning.
- Open windows at night when outdoor temperatures drop to let in cool air.
- Use cross-ventilation by opening windows on opposite sides of your home.
- Install ventilation vents or attic fans to pull hot air up and out of the home.
Educate Your Household About Energy-Efficient Practices
The efficiency of your AC system depends on collective household habits.
- Encourage family members to keep doors and windows closed when the AC is running.
- Create a cooling schedule everyone can follow to reduce unnecessary use.
- Reward energy-conscious behavior, especially with kids, by turning it into a family game or challenge.
Harness Solar Power for Eco-Friendly AC Use
Solar energy can offset electricity costs, especially for AC units that run for long periods.
- Install solar panels to power your cooling system sustainably.
- Combine solar with battery storage to maintain operation even during peak-rate hours or outages.
- Explore government incentives and tax credits available in 2025 for solar adoption.

FAQs
- What is the most energy-efficient temperature to set my AC during summer?
The U.S. Department of Energy recommends setting your thermostat to 78°F (25–26°C) when you're home for optimal efficiency and comfort. Raising it by 7–10°F when you're away can lead to significant energy savings without affecting your comfort.
- How often should I replace my AC filter in the summer?
You should replace or clean your AC filter every 30 days during high-use months like summer. A clean filter improves airflow, reduces strain on your system, and helps lower energy bills.
- Do ceiling fans actually help reduce AC usage?
Yes, ceiling fans enhance air circulation and make you feel cooler, allowing you to increase the thermostat setting by a few degrees without sacrificing comfort. They are most effective when used in occupied rooms during summer in a counterclockwise direction.
- Is it worth upgrading to a smart thermostat?
Absolutely - smart thermostats learn your preferences and adjust cooling automatically, helping you cut energy use by up to 10–12%. They also offer remote control and scheduling features for convenience and savings.
- Can using a dehumidifier really reduce my need for AC?
Yes, reducing indoor humidity makes the air feel cooler, so you can set your thermostat a few degrees higher without feeling hot. This leads to lower energy consumption and improved indoor comfort.
