What Happens When You Use the Wrong Size Furnace Filter?

Using an improperly sized air filter or installing it incorrectly can have a significant impact on your HVAC system. The filter won't be able to effectively prevent dust from accumulating on the motors and fans, leading to a dirty oven that can't work properly and potentially damaging the internal components. This can reduce the efficiency of your heating and cooling system, resulting in higher utility bills. It can also cause poor indoor air quality and increase air resistance, leading to more wear and tear on the system.

Before buying a replacement air filter, make sure you check the size of your current one. Air filters for HVAC systems come in a variety of sizes, so if you buy one that is too large, it won't fit properly. If you can't find a standard size filter within the parameters, you'll need to order a custom-sized one. It's important to regularly clean and change your air filter to keep your oven running for a long time without problems and to ensure the safety of your family by ensuring that the air they breathe is clean.

If you moved to a new house or someone changed your air conditioner filters for you, you may find that whoever did the work put the filter the wrong size. Using an incorrect air filter can cause numerous problems with the HVAC system, including lower indoor air quality, higher energy bills, and increased wear and tear on the system. To avoid these issues, make sure you use the right size filter and install it correctly.
