Hot summer weather and rising electricity costs make it important for homeowners to find the right balance between indoor comfort and energy savings. Setting your thermostat correctly is one of the easiest ways to reduce energy consumption while keeping your home comfortable, especially when your cooling system is working its hardest. Below are practical tips to help you choose the best thermostat settings for summer and get the most from your air conditioning service.

Ideal Thermostat Settings for Summer
The U.S. Department of Energy recommends setting your thermostat to 78°F when you are home and need cooling. For homeowners in Fullerton, CA, this temperature provides a comfortable indoor environment while reducing unnecessary strain on your air conditioner during periods of peak demand. If you prefer a cooler temperature, consider increasing your thermostat by one degree every few days until you reach a comfortable setting. Even a small adjustment can reduce cooling costs while maintaining indoor comfort.
When you leave home for work or a short trip, raising your thermostat to approximately 85°F can help reduce energy usage. Avoid setting it significantly higher, as your air conditioner should still run periodically to help manage indoor humidity and protect your home. If you plan to be away for an extended period and weather conditions allow, you may be able to turn your system off after ensuring your home will remain protected from excessive heat and humidity.
Smart Thermostats: Convenience and Energy Savings
A programmable or smart thermostat is one of the most effective ways to improve your home’s energy efficiency. These devices allow you to automatically adjust temperatures while you’re away and return your home to a comfortable setting before you arrive. Many smart thermostats also learn your daily routine and make automatic adjustments that help reduce unnecessary energy use. With proper programming, homeowners can significantly lower their annual cooling costs while maintaining consistent comfort.
Small Adjustments That Make a Big Difference
In addition to proper thermostat settings, a few simple habits can improve your home’s comfort and reduce the workload on your air conditioning system:
- Keep curtains, blinds, or shades closed during the hottest part of the day to reduce solar heat gain.
- Operate ceiling fans in a counterclockwise direction during the summer to improve air circulation and create a cooling effect.
- Use heat-producing appliances such as ovens and clothes dryers during the evening whenever possible.
- Check windows and doors for air leaks to prevent conditioned air from escaping.
These simple adjustments help your air conditioning system operate more efficiently and may reduce the likelihood of unnecessary HVAC repairs.
Routine Maintenance Keeps Your Air Conditioner Running Efficiently
Even the best thermostat settings cannot compensate for an air conditioner that has not been properly maintained. Scheduling seasonal maintenance allows a qualified technician to inspect refrigerant levels, clean coils, replace air filters, and verify that all system components are operating efficiently. Preventative maintenance reduces the risk of unexpected breakdowns and helps your system perform reliably throughout the hottest months of the year.
If your air conditioner runs continuously without adequately cooling your home, it may be time for a professional inspection. Addressing airflow problems or worn components early can avoid expensive “air conditioning repair near me” searches at the height of summer.
When It’s Time to Consider an Upgrade
If your air conditioner is more than 10 years old or requires frequent repairs, replacing it with a newer system may be the most cost-effective solution. Today’s high-efficiency air conditioners feature advanced technology, including variable-speed operation and improved SEER2 ratings, allowing them to deliver better comfort while using less energy.
