We understand that you may not always have a new replacement filter on hand when you want to replace your current one, but it's best to wait until you have a replacement filter. 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 risks serious and costly problems.
Follow our advice and never run your system without one. An HVAC system can work without a filter, but this is not recommended. Without a filter, the system will suck in debris-laden air and return the same dirty air to your indoor environment, contributing to health problems. In a short time, the system will be flooded with dirt and debris, which can cause a malfunction and consume more energy, which will shorten its lifespan. 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. The good news is that yes, you can run the air conditioner while you go to the store.
This doesn't mean you can run the air conditioner permanently without a filter and just sweep your house more often. An air conditioner cannot work longer than 6-8 hours without a filter and not be damaged. More than this, and you could be configuring your system for serious damage. In theory, you can run 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.
Without a filter, dirt and debris are sucked into your air conditioning system and transported back to your home, remaining and accumulating in the HVAC ducts. Both scenarios can reduce air quality and potentially damage the HVAC system, resulting in costly repairs or replacements. The longer you run your air conditioner without a filter, the more likely it will need repairs. Everything from pets to guests, leaking air ducts, and vacuuming can increase pollutants in your home. In addition, during the hot season, expect your energy consumption to increase even more, considering that the air conditioning unit operates continuously. If you don't know where to look or what type of filter you need, it's best to let an experienced HVAC technician do the work for you.
Your air conditioner filter is usually made of spun fiberglass material or of pleated paper or cloth within a frame. Research has shown that many homes and commercial spaces have air that is more polluted than air from the outside environment. By trapping these particles within its fibers, the filter keeps them out of the HVAC system, helping to protect your family and your air conditioning equipment. The air conditioner draws air from the indoor environment and removes heat from it before returning it to the room. If there is no filter to prevent particles from reaching the compressor coil, dirt buildup will occur much faster, meaning the unit is likely to fail much sooner. Unless you want your system to blow dirty air into your home or office and also risk damaging the unit, it is not advisable to run the system without a filter.
Even if your air conditioner continues to operate for a while with the evaporator coils frozen, you will pay more for the energy the system uses without the benefit of a clean and healthy air conditioner. Cleaning the central air conditioning filter helps the unit consistently produce cool air and keep the air in your home clean and healthy. This is perhaps a little more obvious, but without the air filter to filter the dust, your air conditioner will now be throwing dust all over your house. After all, running the air conditioner for more than a day without a filter could affect your system enough to ensure immediate repair of the air conditioner. That said, running your air conditioner without a filter for more than 6 to 8 hours can cause serious damage to your air conditioning system and significantly reduce the air quality in your home. Although it is possible for an AC unit to work without one for some time, it is never recommended as it can lead to costly repairs or replacements down the line.
