What should the air conditioner temperature be in the summer?
Running your air conditioner more will always use more energy, but with careful planning most houses should be able to stay at 78 degrees Fahrenheit in the summer heat without using excessive energy or making you feel too hot.
Can a large AC system control both temperature and humidity?
Unfortunately, the answer is no. The fact is, an oversized AC system does a poor job of controlling both temperature and humidity. That’s because the powerful compressor turns on and off frequently, so the system never runs long enough to remove humidity from the air. Your AC size needs to be carefully calculated using a load calculation process.
Why does my air conditioner only run at one speed?
An air conditioner that’s only capable of running at one speed— basically, on or off—can have the same problems as one that’s too large when it comes to HVAC humidity control. When the unit can only run at one speed, it turns on and runs full blast until the air reaches set temperature.
What should the temperature be in a window air conditioner?
A dual-hose portable system — a less-common design — ran efficiently enough to cool the room down to 76°F, but a window unit that uses about half as much power (660 watts compared to over 1200) could still easily get the room down to below our 70°F set point.
Which is the best temperature for an air conditioner?
According to the Department of Energy 1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling. But in reality, this is a question that doesn’t have a “one size fits all” answer.
What should the thermostat be when the AC is running?
However, when homes start to grow hotter than normal while the air conditioning system is running, people often resort to a simple “solution”: they turn down the thermostat further. The recommended temperature setting during the summer is 78°F (this comes from the Department of Energy).
What’s the best way to set the air conditioner?
If you don’t already have one, a better solution is to use a programmable thermostat or even a smart thermostat. These thermostats can be set to automatically raise the temperature when you are away and re-set the system for a more comfortable temperature by the time you return.
When to turn on the air conditioner in the summer?
It happens every year. Outdoor temperatures start heating up, you turn on your central air conditioning, and now it’s decision time: What temperature should I set my air conditioner in summer?
