To save money, set your thermostat down or up 7 to 10 degrees (depending on the season) when you're asleep or away from home. Doing so for eight hours can lower your annual heating and cooling costs by around 10%. A programmable thermostat does the work for you.
Thermostat Operation
You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for 8 hours a day from its normal setting. The percentage of savings from setback is greater for buildings in milder climates than for those in more severe climates.
The best thermostat settings for energy savings
However, generally speaking, in the winter, you can set your thermostat to 68° while awake and lower it when you're asleep or away from home. In the summer, set the thermostat to 78° when you are at home and higher when you are away.
A temperature of 68 degrees Fahrenheit is often considered the best temperature to set thermostat in winter to save money.
Keeping your home at a constant temperature generally means that your HVAC system will run constantly to meet it. This means that your furnace or air conditioner may run when you're asleep, at work, or out of the house. This wastes more energy than the minimal amount that you might save by having it constantly run.
Setting your thermostat too high in the winter and too low in the summer can cause your energy bill to increase by as much as 10 percent or more. Consider keeping your HVAC system's thermostat at a constant temperature, recommended at 68 degrees in the winter and 78 degrees in the summer.
What costs the most on your electric bill? Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
Unplug Unused Electronics
Unplugging electronics when they are not in use can drastically reduce your electric bill. Many devices, such as computers and televisions, still draw power even when they are turned off, so unplugging them can make a big difference in your energy costs.
Leaving a few appliances plugged in may not seem like a big deal, but the costs can add up. According to the U.S. Department of Energy, standby power accounts for as much as 5% to 10% of residential energy use, and homeowners could save $100 to $200 each year on utility bills by unplugging devices that aren't in use.
While there are occupants in the house, it is advised for homeowners to set their thermostats between 68 and 72 degrees to promote maximum comfort. A pleasant temperature for everyone in the house, regardless of the apparel they are wearing, is between 68 and 72 degrees, which is neither too warm nor too cool.
Our recommendation: When you head to work or vacation and want to lower your temperature setting, we would not recommend going below 50 degrees F. This strikes a good balance between conserving energy while preventing problems such as: Frozen indoor pipes. Damage from condensation on furnishings and electronics.
If You're Leaving Home for the Day or Weekend ...
"It's more energy efficient to keep the unit on but turn the temperature setting up," she advises. Turning off the AC unit during the day is not necessarily a bad thing — it is a myth that the AC unit has to work extra-hard to cool off a hot house.
In the winter, set your thermostat to 68 degrees or the lowest comfortable temperature. In warmer months, set it to 78 degrees or higher. It's a no-cost option to reduce energy expenses. At night or when you're going to be away from home for an extended period, adjust the thermostat a few more degrees.
The ideal thermostat temperature in the winter is 68 degrees Fahrenheit when you're at home. Energy.gov suggests that 68 degrees is a good room temperature while you're awake at home but recommends lowering it while you're asleep or away.
Heating and cooling: 45-50%
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
Wash Clothes and Dishes at Night to Cut Energy Costs
During nighttime hours, electricity demand is often lower, leading to potentially lower electricity rates. This means that running appliances during off-peak hours may cost less, contributing to energy savings.
Top 6 culprits for a high utility bill
You're using your appliances in an inefficient way. You've been moved to a new rate structure, like time-of-use. Your utility rates are increasing overall. You continuously change or keep your thermostat set to extremely high or low temperatures.
If you want to test how much power your appliances and devices are using in standby mode, you can buy an electricity usage monitor device. These devices allow you to plug in various tech or appliances and check how much power they're actually using, even in standby mode.
Generally, TVs use between 50 to 200 watts (W) of electricity, depending on the model. Most TVs use less than one amp and connect to a 120-volt outlet. Older TVs that use technology such as Plasma and CRT are much less efficient compared to newer LED and LCD TVs.
Whatever the case, dropping your thermostat instead of turning it off completely can help significantly reduce your heating costs — in some cases by 10%. You'll also maximize your savings by ensuring your home is properly insulated and loses less heat.
Dirty Air Filter Affects My Electric Bill
When the filter is not replaced, dust, bacteria and other particulates build up and air flow becomes restricted. This causes your unit to work harder and longer to cool your home, which in turn, results in an increase in your energy bill.
Thermostat settings play a pivotal role in managing your heating system's efficiency. It's a common misconception that leaving your heating on at a constant temperature is more energy-efficient than turning it on and off. Does turning the heat on and off raise the bill each month? The answer is no.
