When deciding whether or not you’ll turn off your AC, you have to consider your situation. If you will only be gone a few hours, there’s no reason to shut it off. Leaving it running will keep the house cool so you can be comfortable when you get back. However, if you’re going to be at work all day and no one else will be home, it might be a good idea to shut it off. There’s no point in using so much electricity to cool furniture. However, if you live in a really hot place, where indoor temperatures can reach 90 in the summer, you should probably keep it running. Household items can start to be damaged from this kind of heat, and hairspray cans even reach exploding temperature. Also, if you have pets, keeping the AC on will keep them more comfortable.
Of course, you don’t want to simply leave the air running, letting the room get colder and colder as the day goes on. Many systems that attempt to regulate temperature do a considerably poor job at the task. Instead, you can buy a programmable thermostat that can be added to your existing system. They typically cost around $30, and are great for keeping your house’s climate even throughout the day. You can use this handy tool to program your AC to turn off and on at intervals of your choice. Some claim, however, that keeping your AC running at all times is a good thing. They argue that leaving the system off for long periods of time prevents air circulation. When away for extended periods of time, even keeping your system running on 85 degrees should help a considerable amount to keep air fresh, lessen dust build up, and help prevent furniture damage.
Clearly, there are very different views on the issue of AC running. You decide what’s best for you.
