Key facts
- Adjusting thermostat settings higher can save 5-8% on cooling costs per degree.
- Smart thermostats can automatically adjust temperatures to save energy.
- Regular AC maintenance improves efficiency and extends system life.
- Home energy audits can identify leaks and suggest insulation improvements.
- Sealing leaks around windows and doors prevents cold air escape.
As millions of Americans prepare for a heat wave, energy experts are advising homeowners on strategies to reduce cooling costs. Simple adjustments to thermostat settings, regular maintenance of air conditioning units, and improving home insulation can lead to significant savings, potentially cutting summer cooling expenses by $100.
Setting thermostats strategically can yield substantial savings. For every degree Fahrenheit above 78 degrees, cooling costs can decrease by 5% to 8%. Experts recommend setting thermostats to 75°F from 6 a.m. to 9 a.m., 80°F from 9 a.m. to 5:30 p.m., 75°F from 5:30 p.m. to 11 p.m., and 80°F overnight. If leaving home for over an hour, setting the thermostat to 85°F or 90°F can further reduce energy consumption. Smart thermostats offer automated temperature regulation based on occupancy and learned habits, with some estimates suggesting up to 50% of programmable thermostats are not utilized effectively.
Maintaining air conditioning systems is crucial for efficiency. This includes cleaning or replacing air filters monthly and scheduling annual professional check-ups for coils and refrigerant levels. Additionally, placing AC condensers on the north or east side of a house, or shielding them from direct sunlight, can improve efficiency by up to 10 percent.
Improving home insulation and sealing air leaks are also key strategies. Home energy audits, whether professional or DIY, can identify areas where cold air escapes through windows, doors, attics, and other cracks. Caulking around windows and adding weatherstripping to doors can prevent this loss, ensuring that cooled air remains inside the home.
