Do I Need a New AC Filter? 7 Obvious Signs You Can't Ignore

Are you wondering if it's time to change your air filter at home? If so, you're not alone. Many homeowners are unsure of when to replace their air filters, and the consequences of not doing so can be costly. Fortunately, there are several signs that can help you determine if it's time to replace your air filter. One of the most obvious signs that you need to change your air conditioner filter is when you can see dirt on the filter.

If the filter is visibly dirty, it's time to replace it. Another way to tell if your filter needs to be replaced is by performing the “white leaf” test. Take a white piece of paper and hold it up to the filter. If you can see dirt on the paper, then it's time to replace the filter.

If you can't remember the last time you changed your air filter, then it's probably time to do so. A clogged filter forces your air conditioner to work harder in order to keep your home cool, which can lead to more frequent repairs and a shorter lifespan for your unit. Another sign that your air filter needs to be replaced is if the back of the unit is too hot. If the filter is heavily soiled, you may feel warm air coming out of the back of the unit.

To reduce the load on your air conditioner, make sure to change your filter regularly. A sure sign that your air filter needs replacement is when it is no longer white. Air conditioner filters turn gray due to all the dust and particles that they collect, so if this happens, change the filter immediately. If you have poor air quality outside or pets indoors, you'll need to replace your air filter more often. Retiring home after a long day in scorching outdoor temperatures and high humidity levels requires an efficiently functioning air conditioning system.

This is because the air conditioning unit has to draw large amounts of air through its filter in order for it to cool or heat your home. Poor indoor air quality has been linked to short-term problems such as eye irritation, headaches, and exacerbation of allergies and asthma. Regardless of what type of HVAC system you have, each unit needs a properly tuned quality filter in order for it to keep your indoor air quality clean and your unit running at peak efficiency. If you decide to clean it yourself, make sure to turn off the power supply first and then use a low-pressure water sprayer with a soft brush in order to clean the coils. If cleaning the air cleaner isn't enough, then an experienced HVAC service technician should investigate the problem and perform any necessary maintenance. A simple way to solve this problem is by checking the filter frequently and cleaning or replacing it when necessary. The bottom line is that if your air conditioner feels hot, check for a dirty filter; replacing it should correct the problem.

If the filter is covered with dust, appears clogged or broken or damaged, replace it as soon as possible. But how often do you need to change your air filter? How often do you need to change your oven filter? Well, it depends on several factors such as how often you use your oven and how much dust and debris accumulates in it over time. Replacement of filters can be done quickly by removing them from their housing and placing new ones. According to the Allergy and Asthma Foundation of America (AAFA), “indoor air quality is just as important as outdoor air quality”. In addition, running your heating and cooling system with a clogged air filter can cause it consume 5-15% more energy than it would if the filter were clean. So if you're wondering if it's time for a new AC filter, keep an eye out for these seven signs: dirt on the filter; failing the “white leaf” test; not remembering when you last changed it; feeling warm air coming out of the back of the unit; gray color; poor indoor air quality; and increased energy consumption.
