Can it be too hot for an air conditioner to work?

Energy Star recommends going no lower than 78F. If that’s too warm for you, drop it one degree at a time until it becomes tolerable. Note that what’s most important is the difference between your AC setting and the outside temperature—the greater the difference, the more it has to work and the more it’ll cost.

Moreover, at what temperature does air conditioning stop working?

The general rule of thumb is that you should never run an air conditioner at 58 degrees F or lower unless you understand the system well enough to know it is designed to be run at lower exterior temperatures than most models — or can be run with the heat exchanger disabled.

One may also ask, what is the maximum temperature differential for an air conditioner? Temperature Differences between Inside and Outside Air This means that it is 80 outside your AC can easily reach 70 degrees, since that is only a 10 degree temperature difference. So even if it is 90 degrees out your air conditioner should still easily reach the 70 degree mark.

Consequently, how cool should my house be if it’s 100 outside?

More specifically, for our area, most systems are designed to lower your indoor temperature about 20°F from the outdoors. So, on days when it’s 100°F outside, and your system is running at its peak efficiency, your indoor temperature will likely never maintain a level lower than about 80°F.

Does heat weather affect air conditioning?

Not only does heat affect how your AC performs on a hot summer day, but humidity plays a major role, too. An excessive humidity level means your AC will be working harder to get rid of that damp, clammy air.
