Optimizing Your HVAC System for Fall Energy Efficiency
As the weather cools, it’s an ideal time to focus on improving your HVAC system’s energy efficiency. Here are some tips to help you save on energy costs this fall:
- Program your thermostat: Set your thermostat to adjust automatically for day and night temperatures. In fall, you might need cooling during the day but heating at night.

- Consider a humidifier: Las Vegas’s dry fall air can make your home feel cooler. A humidifier can add moisture, improving comfort and allowing you to set your thermostat slightly lower.
By implementing these strategies, you can maintain a comfortable home environment while minimizing energy consumption and costs.
