Even if your cooling unit has to run for a while to reach the desired temperature, it still saves more energy and money than running it continuously. Even better if you have a programmable thermostat. Then you only need to set it once and forget it until you turn it off or go away.
Of course, if your current setting is too low, it will take longer for the air conditioner to cool down the room. But this is not usually a problem since people tend to leave their homes before it gets too cold or hot outside.
In conclusion, turning off the heat when you go out or use air conditioning only when needed can help save money on your energy bill while still keeping your home comfortable.
However, as it turns out, the only true advantage to setting your thermostat at one temperature is convenience. Sure, while you're on vacation or out for the weekend, having a regular temperature is beneficial, but when you're at home, there aren't any extra benefits. In fact, by setting your thermostat at one temperature, you're limiting its ability to accurately regulate heat.
The best option here is to set your thermostat to two temperatures: one for morning and evening use, and another for midday use. This allows your house to cool down at night, which saves money on your energy bill and helps prevent damage to your appliances and investment property due to excessive heat.
Of course, if you want your AC to run just once per day, then by all means set it at one temperature. Just be sure to leave the room with all the lights off so that it doesn't turn on when you're not home.
What Is the Best AC Temperature to Save Money on Cooling?
Temperature: 78 degrees Fahrenheit During the summer, setting your thermostat to 78 degrees Fahrenheit is the most effective setting for your air conditioner. Lowering the temperature in your house, for example, to 72 degrees, might boost your cooling bills by up to 47 percent.
This is because people use more energy heating or cooling a small space than doing so at a single temperature. For example, if you have a home with two separate living areas that need different temperatures, setting one area at 72 degrees and another at 78 degrees will require more energy than setting both areas at the same temperature.
Also, remember that your air conditioner needs time to cool down your house after you turn it off. Setting your thermostat at 78 degrees while you're away on vacation will increase your energy usage.
The best way to use less energy while still having a comfortable home is to set your thermostat at 78 degrees during the summer and then only turn the heat on when you'll be indoors for longer than an hour or two. That way you're not wasting energy heating and cooling a empty house.
Of course, you should keep the humidity low as well. A humid environment inside your home increases your energy bill due to the need for air-conditioning.
