![]() ![]() This circulation sucks the hot air from your house and sends it outside. Set the first window fan to blow outwards and the second to blow inwards. Open two windows on opposite ends of your house. ![]() Before turning on the AC, you should do this first: It's only about 80F outside, but your house is sweltering at 90F. ![]() Let's say you've been away from home, and your AC has been off for the entire time. Most central AC units should not be set below 68F, or they will freeze up, which can damage or destroy the compressor. When you're away from home, it's best to set your AC to around 85F, cranking it down to your preferred temperature when you return. The greater the difference, the more it has to work and the more it'll cost. What's most important here is the difference between your AC setting and the outside temperature. ![]() If that's too warm for you, drop it one degree at a time until the room becomes tolerable. Energy Star recommends going no lower than 78F.The Temperature Best for Balancing Comfort and Cost.According to WebMD, the ideal temperature for falling and staying asleep is between 60F and 65F, adjusted to the most comfortable temperature.According to one study by Cornell University, the ideal temperature for office work productivity is around 77F.Hot weather can affect both your ability to work and your capacity to rest. The Temperature Best for Comfort and Productivity.There are two schools of thought when setting your AC's temperature: And if you're away, you can use these simple ways to automate your fans, helping your AC stay efficient all the time.Īdditional Recommendations to Cool Your HomeĪside from the things you should avoid, we have a few more recommendations to help you stay cool. This means you can set your AC to a higher temperature while feeling just as comfortable, shaving a lot off your energy bill on hot days. The same principle applies here.Ĭirculating air also helps your sweat evaporate faster, which has a cooling effect on your skin. If you just watch it sink without stirring, it could be some time before the particles dissipate, achieving equilibrium and distributing themselves throughout the water homogeneously. Imagine squeezing a drop of blue food coloring into a glass of cold water. Unfortunately, this can often be a painfully slow process you can force the cool air to circulate throughout the space by using a fan to move things along. To cool down the rest of your home, you'll have to wait for the thermal transfer to get the job done naturally. For central units, the coolest spots are right around the vents. This means the area right in front of the unit is cooler for window AC units. If you're tired of coming home to a hot and stuffy house, consider getting one of the best smart thermostats for your home.Ĭool air accumulates wherever it gets dumped out. The lesson: set your AC unit to your ideal temperature and let it work. Now, you're simply too cold and have unnecessarily wasted a lot of energy. If, for example, your ideal temperature is 72F, and you set the unit for 65F, the unit will keep going until the room hits 65F. This is because the AC unit will keep working even after it reaches your ideal temperature. It's the worst thing that you can do in this situation. The temperature setting only tells the unit when to stop pumping out cool air changing the setting from 70F to 65F won't speed up the process. Your AC unit continuously pumps out the same "strength" of cool air, whether your room is 70F or 90F. What do you do? You might think that the best course of action is to crank your AC all the way down to 65F so the room will cool faster-but that's not how air conditioning works. After coming home from a long day at work, you step inside, only to be slammed by a thick wall of stale, 90F air. ![]()
