An HVAC system can technically operate without a filter, but this is not recommended. Without a filter, the system will draw in debris-laden air and return the same dirty air to the indoor environment, which can lead to health problems. Although it is possible to run the air conditioner without a filter, it is never advisable to do so. It is best to wait until you have a replacement filter before running the system.
Running the air conditioner without a filter is worse than running it with a dirty one. Instead, go to the store as soon as possible for a replacement or call an HVAC professional to have it replaced. Without a filter, your air conditioner is at risk of serious and costly problems. Therefore, it is important to never run your system without one.
The longer you leave your air conditioner running without a filter, the more likely you are to have problems with indoor air quality. As a result, you or others in your household may experience increased symptoms of allergy, respiratory problems, eye irritation, or irritation of the nose and throat. In theory, you can operate your air conditioner without a filter for a limited period of time. However, doing so for more than 6 to 8 hours can be detrimental to your system and reduce the quality of your home's indoor air.
The evaporator coils are filled with refrigerant, which is a substance that absorbs heat from the air in the house. An air conditioner works by drawing air from your home and blowing it through copper tubes filled with refrigerant. Without a filter in place, dirt, dander, and other debris won't leak out of the air and can be harmful not only to your HVAC system, but also to your health and that of your family. Remember that a clogged air filter prevents air from flowing through the system, which can lead to poor airflow, cold air in winter, warm air in summer, costly utility bills, HVAC system overheating, or premature failure.
This is perhaps a little more obvious, but without the air filter to filter dust, your air conditioner will now throw dust all over your home. So can the HVAC system work without an air cleaner? The short answer is that the system will run, but in this case just because it can doesn't mean you should do it especially as a long-term solution. Each air conditioning system has a filter designed to prevent dust from entering both your home and the system. Without a filter in place to trap pollutants and air pollutants, the air quality in your home will quickly deteriorate because they will continue to circulate around your home until someone breathes it in or builds up inside the HVAC unit. Without a filter, you don't have a chance to avoid all of these air pollutants when you return to your indoor environment.
Next, let's see how the air filter works and the negative effects of running the air conditioning system without one. Instead of running without an air filter, call Air Pros if you have problems with your filter or other parts of your air conditioner. One way to do this is to keep the air filter clean and always make sure it is in place before operating the system. The air conditioner draws air from your indoor environment and cools it before re-dispensing it into your indoor environment.
