Air filters are essential components of any HVAC system, as they help to clean the air and protect the engine from damage. They should be installed on the return side of the air handler, close to the thermostat, or right next to the air conditioner. Additionally, you may want to invest in HEPA filters with a MERV rating of 10 or higher to improve indoor air quality and eliminate pollen, mold, and other contaminants. Finding the air filter can be tricky in some HVAC systems, but it is usually located in the return air duct.
This is typically a large metal grille on the wall, floor, ceiling, or door of the utility closet. If you're having trouble locating it, you can ask a professional for help. They can show you where the filter is located, how to remove and replace it, and which type of filter is best for your system. It's important to note that oven filters and AC filters are not the same.
Oven filters are usually located inside a box in a location that will filter the air before it reaches the fan. AC filters are usually placed on an intake grille or in a holder in the return air chamber. The edge of most air filters has an arrow showing the intended direction of air flow through the filter. Knowing where your air filters are located and inspecting them regularly is key to keeping your HVAC system running efficiently.
If you find that your filter is dirty or clogged, make sure to replace it as soon as possible. This will help reduce energy costs and ensure that your system is working properly.
