Air conditioners use a lot of electricity, but a loss in efficiency will cause high electric bills. Dirty filters, duct leaks, failing parts (motors, capacitors, etc.), low refrigerant, lack of maintenance, old system, and a bad install are all reasons your air conditioner itself will cause high electric bills.
Conclusion. The answer to the question “is it cheaper to leave your air conditioner on all day?” is a resounding yes. You'll save money on your energy and repair bills, especially during the summer months.
According to the Department of Energy1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling.
If that temperature falls outside your comfort level, there are several ways to modify how your home feels without causing your energy bill to spike. Keep in mind, each degree set above 72 can save you up to 3% on your cooling costs.
Since air conditioners use more energy when they cycle all day, it is cheaper to let your system operate at full capacity when you're home instead of running it at a lower capacity all day. The more energy you use, the more money you'll pay in monthly utility bills.
Your AC will actually run longer overall if it is left on all day instead of being shut off. If you turn it off for part of the day, it runs less and results in more energy savings for you. In almost all cases, it will save you money to shut off your AC while you are away from home.
The startup process for a furnace consumes more energy than simply running the entire time at one set temperature, costing you additional money. To maximize efficiency, it's best to keep your furnace (or AC) at the same consistent temperature for long periods of time.
Related Story. It may seem like a waste of energy to turn your A/C on and off, but doing so actually saves you a fair amount of money, Amann says. "Air-conditioning systems run most efficiently when they're running at full speed," she explains.
Does keeping your AC higher save money?
The reason raising the temperature saves money is simple: when the thermostat's setting is higher, the unit itself doesn't have to work as hard to keep the air inside the home close to that setting, resulting in less energy usage.
While running your air conditioner will cool your home, it consumes a lot of energy, leading to higher electricity bills.

How cool should my house be if it's 100° outside? The majority of air conditioning units are designed to only cool the air about 20 degrees from the outside temperature. If the temperatures outside are approaching triple digits, you should set your thermostat at about 78°.
When setting your thermostat, most homeowners find 72 is a good temperature for air conditioning. However, you may need to adjust that setting based on weather conditions. The bigger the difference between indoor and outdoor temperatures, the higher your energy bill will be.
While you ultimately must decide what temperature you feel comfortable at, the US Department of Energy and Energy Star suggest that the best AC temperature is 78°F for summer days.
Sleeping in a room with the air conditioner set to an appropriate temperature is important for quality sleep. The ideal AC temperature for sleeping is around 65°F (18.3°C). However, this may differ between individuals, who might find their ideal AC temperature lies between 60 and 67°F (15.6 and 19.4°C).
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. Lowering your thermostat 7-10 degrees for eight hours a day can reduce your annual heating expenses by as much as 10 percent.
Does turning down the thermostat save money? Yes, homeowners can save money on their energy and heating bills by turning the thermostat down. You can save almost 15 percent of your total heating bill by lowering your heat by seven degrees overnight (or for any other eight hour period).
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.
Choosing the Auto Setting
If you set your preferred temperature very low, your air conditioner is still going to run longer than necessary. But using the AUTO setting with a reasonable set temperature will keep your energy costs low, especially if you turn your unit off when you're away from home or asleep.
Is it OK to leave AC on for a week?
Conclusion. For most homeowners who are going on vacation for a week or two, it's probably best to keep your air conditioner on. But there's no need to cool your entire home the same way you normally do—so turn your thermostat up. If you use a programmable thermostat, look for a vacation, hold, or away function.
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
How Many Hours Should I Run My Air Conditioning Unit Each Day? Modern air conditioning units are designed to run 24 hours a day. There is no harm in having it run to keep your home cool all day long. If you wanted to, you could have your AC unit running 24 hours a day, seven days a week.
According to the Department of Energy, the best AC setting for summer is 78 degrees Fahrenheit. A setting of 78 degrees is often ideal because it offers the best of both comfort and energy savings.
68 to 72 degrees is a temperature range that is not too warm or cool, and is sufficient enough to warm up the home just enough so that everyone is comfortable regardless of the type of clothing they have on.
Generally, when you are at home, your A/C's ideal temperature is between 76- and 78-degrees Fahrenheit. If you spend most of the day away from the house, set the thermostat a few degrees higher instead of cooling your home for no reason.
It usually takes around two and a half to three and a half hours to cool your house from 80 to 72 degrees. However, a variety of different factors can affect the time it takes to reach the desired temperature, including the thermostat setting, the size of the house, and the efficiency of the air filters.

A dirty air filter
Your air filter is designed to trap contaminants in the air before it gets pulled into the AC system. But over time that means that your filter gets dirty and clogged. And if a dirty filter isn't replaced, it can seriously limit your AC's cooling power.
Change the Filter
If your filter is loaded with dust and dirt, it could be causing your air conditioner to not run effectively. If you haven't changed your filter lately, now might be the time to do so. Filters keep dust and other contaminants from building up in your air conditioner.
HVAC experts say that it's completely fine for your AC to run all day. Some AC units are designed to work at full capacity, and some people get this AC installed in Everett, WA. It's always better to schedule an annual check and get your AC repair in Everett, WA, when needed.
When trying to find the most reasonable setting for your air conditioner, you have to start somewhere. And, the best spot to do it at is 78 degrees Fahrenheit. According to Energy Star, it's an ideal temperature. 78 degrees keeps you fairly cool and comfortable during the day.
The refrigerant no longer absorbs as much heat and the temperature in the coil drops, causing the evaporator coil to freeze and making the system inoperable until it defrosts. Thus, temperature setting below 68 degrees is generally not recommended for optimal performance.
On those sweltering 100 degree summer days, your air conditioner should be running almost continuously. This holds the temperature inside your home close to the setting on the thermostat.
70-75 Degrees is the Most Popular Average Indoor Temp Year-round. Half of the respondents set their thermostats between 70-75 degrees during the Summer. Nearly 20% of consumers set their thermostats between 66-70 degrees.
Does turning the AC on and off save money?

MONEY MAY: Set your thermostat at 78 this summer to save on energy costs. Every degree below 78 degrees Fahrenheit that you reduce your thermostat will add about 3% to your energy bill per degree.
Choosing the Auto Setting
If you set your preferred temperature very low, your air conditioner is still going to run longer than necessary. But using the AUTO setting with a reasonable set temperature will keep your energy costs low, especially if you turn your unit off when you're away from home or asleep.
Tip 1: Set the Dial Higher
For a typical household, setting the thermostat at 80 degrees saves 10 to 15 percent; raising it to 85 degrees will save 35 to 55 percent.
Whether or not you realize any savings depends on a few factors: The outdoor nighttime temperature. If the nighttime air that comes into your home cools the indoor temperature to lower than you usually set the thermostat for the air conditioner, turning off the AC should save you some money.
Leaving your air conditioner on is actually more efficient than frequently turning it on and off. Having your AC on also allows you to better control humidity in your home throughout the day. The lower the humidity in a home, the more comfortable it feels during hot weather.
Most AC units are not designed to cool a house below 70 degrees, and you risk the system freezing up. We recommend trying to keep the temperature inside your house below 80 degrees at all times during the summer. At 80 degrees, there's a good chance the humidity level in your home will be very high.
In cut-off mode, the AC will consume less power and help you reduce the electricity bill.
The constant running will reduce pressure in the cooling coil until it freezes over, which is dangerous as it can cause liquid refrigerant to flood back to the compressor and damage it (the compressor is a very expensive part).
Debunking a Common Air Conditioner Myth
Many speculate that this is because your system doesn't have to use excess energy every time you turn it back on. While this might sound logical, this is actually 100% false.
