How can I make sure that the temperature in my house is always at least 68 degrees Fahrenheit?

One way to ensure your house stays at a comfortable temperature is to use an HVAC thermostat. You can set it to maintain a certain temperature and adjust it as needed. Additionally, you can install window coverings or blinds on the south-facing windows to block out direct sunlight during the hottest part of the day. Lastly, you could consider using an air conditioner or fan to help circulate air throughout your home.
