After replacing the filter, you should wait at least 12 hours before running the system. If the AC is still not blowing cold air, it could signify that you have a refrigerant leak, a damaged condenser, or your entire mechanical system needs maintenance.
In AC systems, the air conditioner reset button is on the outside unit's lower edge, typically close to the ground. Some models have the reset button located behind the service panel, which may require tools to remove. Reset buttons are usually red or yellow with a clear “reset” label.
Sometimes there is a sensor that detects air filters, often a mechanical rocker switch (actually a button) that prevents operation w/oa filter. If the filter is crooked or a slightly different size,it can prevent the switch from being clicked and thus prevent normal operation. Try jiggling.
Can a dirty furnace filter cause your air conditioner to stop working? Yes. A dirty furnace filter is also one cause for your coil or refrigerant lines to freeze up.

One of the ways is to make sure the air filter is clean. If you find it clogged with debris, clean it with a brush. A popular cause behind an AC that is not cooling is the deficiency of refrigerant or Freon. When refrigerant circulates together with the air, your room will be filled with cool air.

Yes, you should turn off your AC if it's not cooling.
Maintaining a clean air filter is a small but crucial task that can have a significant impact on your AC system's performance and your overall comfort. By regularly cleaning or replacing your air filter, you ensure proper airflow, improve air quality, and prevent unnecessary strain on your AC unit.
Check the thermostat
You should check if it's been set to the correct temperature and also make sure it's set to “cool”. If the AC settings are not right, it won't turn on. You can also check if the batteries in the thermostat are fresh and replace them if needed.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
Check these issues when the unit won't kick on: Check the thermostat and adjust the settings if it isn't set to Cool and an appropriate temperature setting to call for cooling. Examine the house circuit breakers for the AC unit and reset any tripped breakers. Check the air filter and replace the filter if it's dirty.
Many people wonder, “Can a dirty air filter cause my AC not to cool?” The simple answer is “yes.” A dirty filter can create several problems that can hinder your unit's effectiveness.
Once you locate it, turn the knob to the off position and leave it for at least 30 minutes up to an hour. This will allow the electrically operated components in the AC to reset. Keep in mind that even when the power is off, there could still be some electric charges within the components.
It will be harder for the air to flow, which would take a toll on your system. More strain means spiked utility bills. The metal mesh can trap debris and affect the airflow and quality. It will decrease the efficiency of the air filter and reduce its durability.
Check Your Circuit Breaker
Locate your main circuit breaker and switch it back to the "On" position. Wait 30 seconds and turn on your air conditioner again. If it still doesn't work, you'll need to call a professional for help.
You go to turn on your air conditioner but nothing happens. Why? Usually, it means that your system is not receiving power or that your thermostat is not set correctly. Make sure that your thermostat is set to “cool.” You may also need to adjust the temperature that it's set to.
Blowing the fuse cuts the power to the unit to prevent electrical damage. If your AC has shut down and won't start again, especially if you've noticed odd electrical behavior immediately before the shutdown, chances are the fuse has done its job and will need to be replaced.
You might wonder about the risks of running your AC without a filter, even temporarily. The simple answer is: not for long. Ideally, your AC should never operate without a filter for more than 6-8 hours. Going beyond this can negatively affect both your system's health and your home's air quality.
Turn the unit off. Turning this off prevents the air from blowing dust and grit into your system. Open up your vent and remove the used filter. Make sure the Air Flow Arrows are pointing toward the HVAC Unit.
Power down your AC: Turn off your AC unit and unplug it from the power source. This will ensure that you stay safe while working on the unit. Locate the reset button: Most air conditioning units have a reset button located near the outside unit. It is usually a small button located inside a small hole.
A common reason your air conditioning unit may not be cooling is due to dirty filters. Pollen, dust, pet dander, and other particles can accumulate on your filter and obstruct airflow. Your system will continue to run but with significantly decreased cooling capability.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
