| Signs | What It Means |
|---|---|
| High Humidity | Air feels sticky and heavy; sweat doesn’t dry |
| Heat Waves | Long, hot days make staying cool difficult |
| Sudden Hot Days | Temperature spikes signal need for AC |
Energy Efficiency Tips
Using a smart thermostathelps save energy by setting the right temperature. Set the thermostat to a comfortable level, like 78°F, when you are home. Raise it a few degrees when you are away or sleeping. This simple change reduces power usewithout losing comfort.
Scheduling AC usage during off-peak hourscan lower energy bills. Many utilities charge less during these times. Use a timer or smart controls to turn the AC on before you return home. This way, the room cools without running all day.

Natural ventilation works well when the air outside is cooler than inside. Open windows and doors on opposite sides of a room. This creates a breeze that cools your home. Close windows and curtains during the hottest parts of the day to keep heat out.
| Shade Techniques | Insulation Techniques |
|---|---|
| Use curtains or blinds to block sunlight. | Seal cracks around windows and doors. |
| Plant trees or install awnings outside windows. | Add insulation in walls and attic to keep heat out. |
| Apply reflective window films to reduce heat. | Use weather stripping to prevent warm air entry. |
