The short answer is yes, your HVAC system can operate without a filter. However, just because you can doesn't mean you should. Running your HVAC unit without a filter is probably OK for a short period of time, but continuing to do so for more than six hours is already delaying it. 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.
A common problem if you operate your air conditioner without a filter is that the indoor air quality will deteriorate. As dust and dirt penetrate the interior of your air conditioner, this contaminant will recede repeatedly and remain suspended in the air. 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. 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. Evaporator coils contain a substance called refrigerant, which absorbs heat from indoor air so that the air conditioning system can return cool air to your home or office. Cleaning the central air conditioner filter helps the unit consistently produce cool air and keep the air in your home clean and healthy. An air conditioner works by drawing air from its environment and blowing it back through the fiberglass tubes of the freon air conditioner.
You can choose to replace the filter later in the evening or on a day when local stores that sell filters aren't open. The function of the air cleaner, together with the compressor motor and evaporator coils, is to prevent air pollutants from entering the air conditioner. Because your HVAC system relies on a filter to remove impurities before indoor air is drawn into the system and then expelled back into the room, you need the filtration system to be clean and efficient so that hot or cold air can make your commercial space or home comfortable. The air conditioner draws air from the indoor environment and removes heat from it before returning it to the room. Commercial and residential cooling and heating systems need a filter to remove impurities before they suck indoor air into the system and exhaust it back to areas that are supposed to heat or cool. The primary purpose of your air conditioning filter is to clean the air circulating through the air conditioning system. Having a clogged air conditioning filter requires your air conditioning unit to work in excess of its usual work.
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. An air conditioning system that works without a filter will have a major negative impact on indoor air quality, possibly even causing the spread of diseases or an increase in allergic reactions. Periodic maintenance of your air conditioning filter will ensure that the air conditioner dispenses the best air quality that suits the conditions required by your environment. A dirty filter forces the HVAC unit to work harder than normal because it finds it more difficult to draw air.
