With the escalation of summer heat, our reliable companion, the air conditioner, becomes indispensable. Though these devices serve us relentlessly, they also require our attention to function safely and efficiently throughout the summer’s hottest days.
What Should I Set My AC To?
Determining the optimal setting for your AC involves several factors.
- Temperature Variation: Your home’s temperature will fluctuate throughout the day as the outside temperature increases.
- Space Occupancy: The occupancy of your space is another vital factor. To avoid unnecessary energy expenses, consider raising the temperature when you’re away from home.
- Programmable Thermostats: These devices can be a practical solution to manage your AC’s operation, preventing it from running incessantly when not needed.
Can You Run an AC All Day in 100 Degree Weather?
Constantly running your air conditioner can cause the evaporator coil to freeze over. If you find the unit is blowing warm or room temperature air, but when you touch the side of the unit, it’s cold, then the evaporator coil may have frozen. You’ll want to turn on the fan and turn off the cooling mod to allow the coils to defrost. Also, check that the filter and coils are free of dust.
Air filters can clog faster when the unit is working harder. You can do some basic maintenance by cleaning them off or replacing them yourself.
What Should My AC Be Set at in Summer?
According to the U.S. Environmental Protection Agency (EPA), people should set their AC units to 78 degrees in the summer for maximum savings on utility bills. When no one’s home, they also suggest setting your thermostats to 85 degrees to help save on energy costs.
However, many homeowners prefer to keep their AC unit’s set to 72 in summer weather for comfort. If you’re attempting to save on your bill, you can steadily raise the thermostat generally over time and supplement your cooling needs with fans or personal coolers.
Does Air Conditioning Work in 100 Degree Weather?
Your HVAC system operates at its peak when the external temperature rises above 95 degrees. Under such conditions, your indoor temperature may hover just below 80 degrees. However, setting a lower temperature might overburden your AC unit without significantly lowering your home’s temperature. In such cases, deflecting the sun’s hot rays using blinds or thermal curtains can enhance comfort.
Can It Be Too Hot for an AC to Cool Your Home?
We all have our limits when it comes to the summer sun, and our HVAC systems are no exception. Most AC units are designed to cool approximately 20 degrees below the external temperature. So, on those sweltering days, it can feel hot indoors. On days like this, it’s important to understand that lowering the temperature only makes the AC work harder and may not necessarily make your home any cooler.
To help your AC fight the hottest summer days, remember to:
- Keep your blinds closed.
- Consider investing in blackout or thermal curtains.
- Shut doors to any unused rooms.
- Turn on a ceiling or box fan.
