When it comes to improving your air conditioner’s energy efficiency, one of the simplest yet most effective strategies is adjusting your thermostat settings. Many homeowners and business owners underestimate the impact the thermostat can have on energy usage, but even small changes can lead to significant savings.
In this blog post, we’ll break down why your thermostat matters, how to set it for maximum efficiency, and smart upgrades you can make to boost comfort while lowering your energy bill.
Why Thermostat Settings Matter
Your air conditioner works hard to maintain a comfortable indoor temperature. The lower you set your thermostat, the harder your system works — and the more energy it consumes. By simply raising the thermostat a few degrees, you reduce the strain on your AC and save money in the process.
According to the U.S. Department of Energy, you can save up to 10% annually on cooling costs by adjusting your thermostat by 7–10°F for 8 hours a day from its normal setting.
The Ideal Temperature Settings
Here’s what energy experts recommend:
- When You’re Home:
Set your thermostat to 78°F (26°C). This is considered the optimal balance between comfort and energy efficiency for most people. - When You’re Away or Asleep:
Increase the temperature to 85°F (29°C) or higher if no one is home. At night, if you’re comfortable with it, raise the temperature slightly or use ceiling fans to assist cooling. - Avoid Constant Adjustments:
Frequent manual changes can cause the system to work inefficiently. Instead, follow a consistent schedule.
Use a Programmable or Smart Thermostat
If you’re still adjusting your thermostat manually, it’s time to upgrade.
- Programmable Thermostats allow you to schedule different times of the day and days of the week. For example, you can set it to cool down before you leave work.
- Smart Thermostats take it a step further — they learn your habits, detect when you’re home or away, and adjust temperatures automatically. You can also control them remotely via your smartphone.
Popular options like Google Nest, ecobee, and Honeywell smart thermostats offer energy reports, voice control, and integration with other smart home devices.
Additional Tips for Thermostat Efficiency
- Don’t place heat-generating appliances (like lamps or TVs) near the thermostat — they can cause false readings.
- Keep doors and windows closed when the AC is on.
- Use fans strategically to circulate air, allowing you to set the thermostat slightly higher without losing comfort.
- Ensure proper insulation and sealing around the home to maintain the set temperature with less effort.
The Bottom Line
Adjusting your thermostat is one of the easiest and most affordable ways to boost your air conditioning efficiency. With the right settings and a smart approach, you can stay cool and comfortable while lowering your electricity bills.
