Air conditioning accounts for 50-70% of summer electricity use for APS customers. Combined with longer daylight hours, pool pumps, and increased appliance use, summer bills can be 2-4x higher than spring or fall. APS may also apply seasonal rate adjustments during peak summer months.
Some APS rate plans include demand charges that increase during summer months when the grid is under the most stress. Time-of-use rates are typically highest between 2-8 PM on summer weekdays. Shifting usage away from these peak hours can significantly reduce your bill.
Set your thermostat to 78°F or higher when home. Use ceiling fans to feel cooler. Close blinds on sun-facing windows. Run major appliances before 2 PM or after 8 PM. Consider a smart thermostat that pre-cools your home before peak hours. These strategies can reduce your APS summer bill by 15-30%.
