What Temperature Should You Leave Your Central Air Conditioning On When Nobody Is Home?
What serves as the “best temperature” for your home is naturally going to vary from person to person. But, while we can’t tell you what the perfect temperature for you is, what we can do is tell you how to best save money on your energy bill when nobody is home.
As tempting as it may be to leave your HVAC system running cool for the entirety of your absence, this practice is actually inefficient and will cost you more money than you may realize. We understand, though, if you don’t want to turn your system off completely. To find the middle ground, you’ll want to factor in the outdoor temperature, whether or not you have any furry family members being left in the house, and when you plan on returning.
To start, match your thermostat setting to the outside climate, you’ll essentially be maxing out the efficiency of your system. For example, if the temperature outside is 82 degrees and you set your thermostat to 82 degrees, your AC will not be actively blowing cool air, but it also will never get any warmer than about 82 degrees exactly. Regardless of how long you leave your system on, it will not be consuming additional energy or increasing your bill.
That being said, just because there are no people left inside doesn’t mean there is nobody left inside. If you have a cat, dog, or other pet who will be at home while you’re out, and the projected high for the day is dangerous, you don’t want to burn out your four-legged family member by meeting the outside temperature. Set your system to a warmer-than-normal-but-still-comfortable temperature to prevent your animal from suffering heat stroke. In this case, safety overrides financial efficiency.
Finally, if you’re going to be gone for a long period of time and your house will be completely and entirely empty, you’re better off switching your system to the “OFF” position altogether and pinching every penny you can. If you know you’ll be back relatively shortly, however, simply raising the internal temperature for awhile will afford you some comfort while still saving a little more money.
