Even the best air conditioners run into mechanical problems. When this happens, one of the first things HVAC experts will implore you to do is turn it off. This task sounds simple — and it is — but there’s a proper way how to turn off your air conditioner. To turn off an air conditioner, first locate the power switch, which is typically on the unit itself or on the wall. Turn the power switch to the ‘off’ position. If your AC unit has a remote control, ensure it is also turned off, or the batteries are removed.
And as a logical next step, you can also read our article on how to turn on a central air conditioner.
Additionally, if you’re stuck on AC filters, you’ll want to consult our guide on what size air conditioner filter do I need.
People need to turn off their central air conditioning units for many reasons; for instance, during winter months, the blower is used to circulate warm air for comfort. This sometimes means unlocking the A/C thermostat first. Sometimes it is to lower energy costs or mechanical issues — like poor electrical circuit connection or a refrigerant leak. You also might need to turn it off for running tests (see how to test an air conditioner compressor). Other maintenance is cleaning and straightening out the air conditioner fins and unclogging the air conditioner drain pipe.
However, the primary cause of reduced cooling capacity and energy inefficiency is a dirty condenser coil, dirty blower fan, and dirt clumps blocking airflow.
Install a programmable thermostat if you’re looking to save money on your AC. These save homeowners up to $180 a year.
These are all circumstances under which you’ll need to know how to turn your AC completely off for a longer period of time. Below is a step-by-step guide on how to do this safely and efficiently.
Don’t turn off your AC if you’re only going out for a couple of hours. It requires a lot of energy to start a central AC unit, resulting in higher energy bills.

Should the air conditioner ever be turned off?
Usually, you shouldn’t shut off an AC for a short period. However, if you plan to leave for a trip or put it in hibernation for winter, it is good to shut it off.
Why isn’t the air conditioner turning off?
Suppose your air conditioning unit is constantly running. In that case, this problem can sometimes be attributed to frozen evaporator coils or a clogged air filter.
Should the AC be turned off at night?
Turning it off at night isn’t a good idea because an AC uses much more electricity to start the cooling cycle than to keep it running.
