When summer temperatures rise across New Jersey, so do energy bills. Many residents assume the only way to stay comfortable is to keep lowering the thermostat, but that often leads to higher costs without solving the underlying problem. The good news is that a few simple changes can help you stay cool while reducing your monthly utility expenses.
Adjust Your Thermostat Strategically
One of the easiest ways to save money is by raising your thermostat a few degrees. The U.S. Department of Energy recommends setting your thermostat as high as comfortably possible when you’re home and increasing it further when you’re away. Using a programmable or smart thermostat can save up to 10% annually on heating and cooling costs by automatically adjusting temperatures throughout the day.
If your home feels uncomfortable at higher temperatures, the issue may not be your air conditioner, it could be poor insulation, air leaks, or high indoor humidity.
Replace Your Air Filter
A dirty air filter restricts airflow and forces your cooling system to work harder. Replacing or cleaning your filter every 1–3 months helps improve efficiency, maintain airflow, and reduce strain on your HVAC system.
This simple maintenance task can also improve indoor air quality by reducing dust and allergens circulating through your home.
Use Ceiling Fans Correctly
Ceiling fans don’t lower the temperature of a room, but they help people feel cooler by moving air across the skin. During summer, fan blades should rotate counterclockwise to create a cooling breeze. Using fans allows many households to raise the thermostat several degrees without sacrificing comfort.
Keep Sunlight Out
Direct sunlight can significantly increase indoor temperatures, especially during the afternoon.
To reduce heat gain:
- Close blinds and curtains during the hottest part of the day.
- Use blackout curtains on sun-facing windows.
- Consider exterior shades or awnings for heavily exposed areas.
Limiting solar heat gain reduces the workload on your air conditioner and helps rooms stay cooler longer.
Seal Air Leaks
Many New Jersey homes lose cooled air through gaps around doors, windows, attic hatches, and utility penetrations. Even a well-functioning AC system will struggle if conditioned air is constantly escaping.
Air sealing helps:
- Reduce cooling costs
- Improve comfort
- Eliminate drafts
- Reduce humidity issues
According to ENERGY STAR, homeowners can save an average of 15% on heating and cooling costs by air sealing and adding insulation.
Check Your Insulation
Insulation isn’t just for winter. During the summer, insulation slows heat transfer from hot attics and exterior walls into your living spaces.
Homes with inadequate attic insulation often experience:
- Hot upstairs rooms
- Uneven temperatures
- Constant AC operation
- Higher utility bills
Proper insulation helps your home maintain a more stable indoor temperature while reducing the demand on your cooling system.
Avoid Creating Extra Heat Indoors
Many everyday activities generate heat that makes your AC work harder.
Try to:
- Run dishwashers and laundry machines during the evening.
- Use grills or outdoor cooking when possible.
- Limit oven use during peak afternoon hours.
- Switch to LED lighting, which produces less heat.
Small changes like these can make a noticeable difference during extreme heat waves.
Schedule HVAC Maintenance
An air conditioner that hasn’t been serviced in years may be running far less efficiently than it should. Routine maintenance can identify issues such as:
- Dirty coils
- Low refrigerant levels
- Electrical problems
- Airflow restrictions
Annual tune-ups help your system operate more efficiently and can extend its lifespan.
Look Beyond the Air Conditioner
If your home is always hot, humid, or expensive to cool, the problem may not be the AC itself. Many comfort and energy issues are caused by air leakage, poor insulation, duct problems, or other whole-home performance issues.
A home energy assessment can identify where your home is wasting energy and recommend improvements that reduce cooling costs while improving comfort year-round.
