As temperatures rise, so do your energy bills when you use your air conditioner. But does turning off the air conditioner save money? Let’s dive into the world of HVAC systems, energy efficiency, and cost savings to uncover the truth about whether turning off your air conditioner saves money.
Summary
- Turning your AC on and off might seem like a way to save money, but it can actually raise your energy bill.
- Never underestimate humidity on hot days. It makes your home feel hotter than it is, which means your AC is working harder than it needs to.
- A programmable or smart thermostat is one of the easiest upgrades you can make to let it quietly save you money in the background.
What Happens When You Turn Off Your AC
When you turn your air conditioner off and leave for the day, your home doesn’t actually stay at the temperature you set. On a hot day, the temperature in your home gradually rises due to the heat transfer from the outside. When you turn the AC back on, your system then runs at full capacity for an extended period to remove that built-up heat. It also uses a large amount of electricity in a short window of time just to get back to a comfortable temperature.
Is It Cheaper To Turn AC On and Off?
It’s not cheaper to turn the AC on and off than to keep it running at a high cooling setting. The AC’s energy spike used to recover from an overheated home typically exceeds the savings gained from having the system off for several hours. The result? More of your money is being sunk into your energy bills.
This is especially true in climates like California, where our summers are unbelievably hot, and the heat constantly seeps into your home. The moment you stop your AC, a wave of heat quickly takes up space in your home, like a house guest who won’t leave.

Is It More Energy Efficient to Leave Air Conditioning On?
Here’s a counterintuitive tip for surviving a California heat wave: it’s actually more energy-efficient to leave your AC on while you’re out — just nudge the temperature up a bit rather than shutting it off completely. That way, your home stays at a reasonable temperature, and your AC runs in shorter, easier bursts instead of having to fight its way back from a sweltering house.
Humidity is also a factor to consider. Your AC isn’t just cooling the air but also pulling moisture out of it. So when you turn it off, and the house bakes in the heat, that humidity creeps back up, and a humid home feels even hotter than the thermometer suggests. To give your AC a break, you can also look into whole-house fans.
Recommended AC Temperature Settings
The experts at the U.S. Department of Energy recommend setting your thermostat to 68°F to 70°F when you’re home and raising it to around 80°F when you’re away for several hours. Your home stays cool enough that your AC doesn’t have to go into overdrive when you get back, but you’re still not paying to cool an empty house all day.
You can also save up to 10% on heating and cooling costs by turning your thermostat back 7°–10°F for eight hours a day. Sometimes, thermostats do fail, and it’s good for homeowners to know why.
The Smarter Move: Use a Programmable Thermostat Instead
One way to optimize your AC usage and save money is by using a programmable thermostat. These devices allow you to set your AC to adjust to the perfect temperature at different times of the day. For example, you can program it to raise the temperature when you’re not at home and lower it before you return. This way, your AC doesn’t have to work as hard, and you still come home to a cool house.
Smart thermostats take it a step further by connecting to your phone, allowing you to adjust settings remotely. If your plans change and you’re heading home earlier than expected on a hot day, you can lower the temperature sooner so the house is comfortable when you arrive. You can also track your energy usage with a smart thermostat as the system learns your cooling and heating habits.
When Turning Off Your AC Actually Does Save Money
There are times, like shoulder season, when turning the AC off does save money. Shoulder season means the period between spring and fall when your home won’t overheat without an AC running. Keeping your home windows open during these times can suffice and save you money on your cooling bill.

Frequently Asked Questions
How much does it cost to run AC all day in Modesto, CA?
The average cost to run an AC all day in Modesto, CA, is between $8.00 and $10.00. That equates to around $300 per month, but easy ways to cut down on this energy usage are replacing your air filters regularly (one to three months) and investing in a programmable thermostat.
Is it bad for my AC unit to turn it on and off frequently?
Yes, frequent on/off cycling puts more wear on your system’s compressor over time. Overall, keeping your AC running at a consistent temperature throughout the day is gentler on the equipment.
Should I use a fan instead of AC to save money?
No, you shouldn’t use a fan instead of an AC to save money. Ceiling fans and portable fans don’t actually cool the air. They create a wind-chill effect that makes you feel cooler, which complements the conditioned air from an AC.
How do I know if my AC is running inefficiently?
Signs of an inefficient AC system include rooms that won’t cool evenly, the unit running constantly without reaching your set temperature, and unusually high energy bills. If you notice any of these, it’s worth having a Loves Air technician take a look.
At what point should I just replace my AC instead of repairing it?
You should replace your AC if it is on the older side (15 to 20 years old) and needs repairs. Another good factor to consider is the 50% rule: if the repairs equal half the cost of a new unit, it’s probably time to replace it.
