Do you have a central air conditioning unit in your home? If so, you may be wondering if it has two or more filters. The answer is yes! Most central air conditioning units have two or more filters that help to clean the air and ensure good air quality as the unit circulates between indoor and outdoor air. These filters are usually made of fiberglass or pleated materials. In a typical home, there are two air filters in the inlet holes. However, this number can vary depending on the size of the house or apartment and the number of floors that must be supported by the central air system.
If you live in a large home, your system will likely require more than one return air duct, and each duct will need its own filter to stop particles before they reach the blower motor. It's also possible that you have a system with several air conditioning units. Larger homes often have more than one HVAC system, and each system will normally have at least one air filter. This means that your home may have air filters located in the air handling unit AND on returns. It's important to check every possible location to make sure you have found all of your air filters. If you're still unsure, you can always contact an HVAC professional for help.
They can provide advice on how to best maintain your system and ensure that it is running efficiently. When it comes to replacing your air filters, it's important to do so at the recommended intervals (usually 90 days). This will help to keep dust from accumulating and covering the air conditioner intake grilles. It's also important to use the right type of filter for your system. You can find filters and humidifier pads for all major manufacturers (including Air King, American Standard, Aprilaire, GeneralAire and Honeywell).The service life of the filters is different, so the number of times you need to replace the air filters in the return duct compared to the air handler varies because they have a different size.
Understanding the parts of your central air system is important because it helps explain cases where multiple air filters are used in multiple locations - this is especially common in two-story houses. The squirrel cage blower is designed to move an air column, restraint and if taken out of the unit and placed outdoors, it would overload the engine. HVAC professionals who simply care about technology and are not part of some corporate entity trying to increase revenues advise against this practice. Start with the premise that for standard replaceable filters, their job is primarily to keep dust and other debris floating from the air out of the oven (air handler) and coil air ducts. By replacing air filters at regular intervals, you can ensure that your family is breathing fresh, clean air without any problems during the winter months.
