As utility rates continue to rise in communities such as Woodland, WA, many homeowners are looking for new ways to lower their home’s energy usage. Turning off the AC at night when the temperature is cooler may make sense.
The Advantage heating and air conditioning team can explain whether this will help you save money on your electricity bill.
Is it effective to turn off the air conditioner at night?
Turning off your AC at night may or may not save you a few dollars on your electric bill. Several factors determine whether you can save:
The Temperature At Night Outdoors
Turning off your air conditioner can save you some money if the nighttime air that enters your home cools the temperature indoors to below what you set for the thermostat.
Humidity At Night Outdoors
The nighttime air may be very humid and bring the humidity within, resulting in your air conditioner working harder than usual to remove the excess moisture.
Energy-saving tips for your AC
Here are some practical tips for lowering your air conditioner’s electricity consumption without sacrificing comfort and indoor air quality:
Upgrade Your Thermostat
Changing the temperature of a room requires the physical adjustment of a manual thermostat. This can result in wasted energy, especially for homeowners who don’t know how to program their thermostats properly.
Do not program your thermostat for a colder setting will result in excessive cooling and higher energy bills. When setting the thermostat, ensure you are in the right heating or cooling mode.
You can save more energy by using a programmable thermostat. The thermostat type manages your home’s temperature efficiently, resulting in a 10 percent energy savings per year.
In more sophisticated systems, the AC unit will cycle off when no one is home, detect if a human is in the room, and control the temperature based on your schedule.
Raise The Thermostat Temperature At Night
A small difference between indoor and outdoor temperatures can significantly affect your energy bill. When it’s not too hot outside, raise the thermostat at night.
Ensure the humidity is controlled while setting the temperature as high as comfortable. By setting the thermostat temperature seven to ten degrees higher than average for eight hours, you can save 10 percent on your energy bills.
At Night, Use Your AC's Fan Mode
Before you go to sleep, switch your AC unit’s operation from cool to fan mode. Air still circulates in the room, but with less effort from the air conditioner since only the blower fan operates.
Natural Ventilation And Fans Are Useful
Install whole-house fans that draw air in through the windows and exhaust it through the roof and attic. For most climates, whole-house fans can provide adequate cooling even during the hottest nights. Consult a professional for safe and proper whole-house fan sizing and installation.
Room fans can make occupants more comfortable. By circulating air in a room, fans create a wind-chill effect. Turn off the fans when not in use or when you leave the room. Open some of the windows crosswise when it’s cold outside to create a crosswind.
