The short answer: You can get away with running your AC without a filter for a short period of time. However, doing so for longer than 6-8 hours can hurt your system and decrease your home's indoor air quality.
As mentioned previously, running your air conditioner without a filter can lead to severe problems. It could lead to decreased comfort and permanent damage to your HVAC system, which may result in hefty repair bills.
Motor and Compressor Malfunctions
Your filter should be stopping dirt, pet hair, and other particulates from ever reaching these parts of your system. When your filter fails to do this or isn't in place, the motor and compressor get dirty and eventually fail to work properly.
Operating your engine without the filter exposes it to dirt, debris, and contaminants that can lead to premature wear and a decrease in overall performance. Over time, repeated testing without the filter could result in greater engine wear and a shorter lifespan for the engine.
Is my AC not working because of the filter? Potentially, yes. While there are a whole host of issues that could cause problems with your air conditioning system, a dirty air filter should be the first thing to check if your central air conditioning unit isn't working as properly as it should.

Maintaining it properly is key, but what happens if you're caught without a replacement filter during maintenance? 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.
Decreased air quality is the most common problem when AC's are run without a filter. Dust will not settle down in a room with an AC running continuously without a filer. This will eventually lead to the clogging of the unit.
A clogged air filter can cause more harm than good. During the day, your AC should cycle on and off, but a dirty air filter can make those cycles more frequent than they should be. Cycling is not only noisy, but it also wastes energy.
Your furnace can, technically, run without a filter. However, we strongly recommend you don't run your furnace without a filter for any length of time. With air constantly moving through your furnace and your home, dust and debris can quickly build up, even in a matter of minutes.
Don't run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs.
DON'T: Forget to Turn Off Your Air Conditioner Before Replacing the Filter. When changing the filter, make sure to turn off your AC completely. Don't just turn your thermostat down; disconnect the AC entirely before filter replacement.
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.
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.
While an air conditioner should normally cycle on when it senses an increase in temperature, and off when it has sufficiently cooled the room off, short cycles can occur when you have a dirty air filter.
When your car is idling or stationary, you should feel and hear the smooth vibrations of an efficient engine. If you notice unusual noises, in particular a coughing, popping or spitting noise, it suggests that the engine isn't getting enough airflow, which means your air filter needs to be replaced.
An average air filter will cost around $10 to $25, although select filters can range in price to well over $100. How do I check my car air filter? Hold your air filter up to the light. If you cannot see light through the pleats, it is dirty and needs to be changed.
The short answer: You can get away with running your AC without a filter for a short period of time. However, doing so for longer than 6-8 hours can hurt your system and decrease your home's indoor air quality.
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. Not to mention, a dirty filter can also lead to premature failure of your system.
Without an air filter in place, the engine may also be sucking dirt and debris in at the same time. This can cause damage to internal engine parts, such as valves, pistons and cylinder walls. The result is excessive oil consumption, poor engine performance, and eventually engine failure.
What happens if your HVAC filter is dirty? A dirty HVAC filter restricts airflow, which can lead to poor system efficiency, increased energy costs, and wear and tear on the unit.
Unkempt air filters may negatively affect indoor air quality by spreading pet dander, dust, and other allergens throughout your home. This may lead to irritated eyes, nose, and potentially breathing problems.
There are a number of reasons why your AC unit may stop working unexpectedly, including electrical problems, blockages, thermostat issues, and more. Troubleshooting includes checking your circuit breakers, thermostat settings, and replacing your air filters.
