This is false. Setting your thermostat to a much lower temperature won't cool your home any faster than setting it to your desired temperature.
Your air conditioning system works at the same rate regardless of how low you set the thermostat. Whether you set it to 68°F or 60°F, your AC unit will run at full capacity until it reaches the set temperature. The difference is that setting it extremely low means your system will continue running well past your comfort zone, wasting energy and money.
If it feels like your home is taking too long to cool, it might be time to check for other issues, like dirty a filter, poor insulation or an inefficient cooling system.
Additional ways to cool your home efficiently
- Use ceiling fans to circulate air. Set it counter-clockwise to create a downdraft, pushing cool air downwards.
- Close blinds and curtains during the day to block heat from sunlight.
- Replace air filters regularly to maintain proper airflow.
- Seal air leaks around windows and doors to prevent cool air from escaping.
- Install a programmable or smart thermostat that automatically adjusts temperatures based on your schedule.
If your AC system is older or frequently requires repairs, consider upgrading to an air-source heat pump, which provides high-efficiency heating and cooling. Make sure to look for ENERGY STAR®-certified models, which are independently tested to ensure energy-efficient performance.
