Living in Texas or any host region during the summer can be challenging, especially in a small residence. One common question is whether to leave the air conditioner (AC) on all day while you’re away. Here are some things to consider that may be best for your situation.
Understanding Your AC
Air conditioners are designed to keep your space cool by removing heat and humidity. When you leave your AC off during the day, the inside temperature of your residence can rise significantly. This means your AC must work extra hard to cool down when you return.
Effects on Your Appliances
Letting your house get very hot during the day can have a few impacts:
Wear and Tear – The constant heating and cooling can cause parts to expand and contract, leading to cracks and other damage over time.
Fridge Performance – Your fridge might struggle to keep food cool when the temperature inside the house gets too high. For example, if your fridge temperature rises above 50 degrees Fahrenheit, it could become a food safety issue.
Energy Use and Cost
Running your AC all day can increase your electricity bill, but there are ways to manage this. Setting your AC to a higher temperature while you’re away, like 85 degrees Fahrenheit, can help keep the house from getting too hot without using as much energy.
Tips for Managing Your AC
Thermostat Adjustments – If your AC has manual knobs instead of a digital thermostat, you can still adjust the intensity to keep it from freezing the unit. Setting it to a moderate level might be best.
Using a Smart Plug – If your AC unit is plug-in, consider using a smart plug with a thermostat function. This can turn your AC on and off based on the temperature, saving energy and reducing wear on the unit.
Shade and Ventilation – Keeping your shades closed and other methods to block direct sunlight into the home will help. Opening windows for ventilation can also help, but be cautious about letting in too much heat or humidity.
Expert Opinions
People in similar conditions often suggest leaving the AC at a higher temperature while away. This prevents the house from getting extremely hot, which can be hard on the AC when it has to cool down from such high temperatures. Additionally, a dehumidifier can help your AC run more efficiently.
Leaving your AC on all day might be more energy-efficient and better for your house and appliances in the long run. Setting it to a higher temperature while you’re away can balance comfort and energy use. If you’re worried about costs, try testing your electric meter with the AC on and off on different days to see the difference in energy use. Consider your specific situation, such as your AC unit type and the insulation quality.
Keeping your house at a manageable temperature all day can prevent damage and ensure a comfortable environment when you return home.
