Optimal Air Conditioner Modes in Summer and Winter for Energy Savings in Glendale

Running an air conditioner efficiently is one of the easiest ways to reduce monthly bills without sacrificing comfort—especially in Glendale, where hot summers and cooler winter evenings can push HVAC systems to work harder than necessary. The key is choosing the right mode, temperature, and schedule. Summer settings: Use COOL mode (or AUTO if it reliably switches) and aim for 24–26°C (75–78°F) when you’re home. Every degree lower can noticeably increase energy use. Pair this with a medium fan speed, closed blinds during peak sun, and a programmable schedule that raises the setpoint by 2–4°F when you’re away. If your unit has ECO mode, enable it to reduce compressor cycling. In humid conditions, DRY mode can feel more comfortable at a higher temperature, saving power. Winter settings: If you have a heat pump, use HEAT mode and target 19–21°C (66–70°F). Avoid frequent manual changes; steady settings are more efficient than constant adjustments. Use AUTO fan when possible to prevent blowing lukewarm air and to stabilize room temperature. Year-round habits: Clean or replace filters regularly, keep vents unblocked, and ensure the outdoor unit has clear airflow. Seal small air leaks around doors and windows, and use ceiling fans to circulate air (counterclockwise in summer, clockwise in winter). Finally, schedule periodic professional maintenance in Glendale to keep refrigerant levels, coils, and sensors operating at peak efficiency.
