AC Filter Issues That Interfere With Cooling
Your air conditioning (AC) filter ensures both the AC and indoor air are clean. However, problems with the AC can interfere with all that. Below are some of these problems.
Dirty Filter
The air filter traps dirt particles bigger than its openings. Over time, the trapped particles accumulate and clog the filter, restricting the flow of air through the filter. Restricted airflow can lead to several complications:
- The AC will take a long time to cool the house
- The AC motor will overwork and overheat while trying to cool the house
- Your house might experience cold and hot spots due to inefficient cooling
- The evaporator coil might freeze
- The AC might experience frequent malfunctions
The solution is to replace your filters regularly. The ideal replacement period can range from three weeks to six months, depending on your unique circumstances. The type of filter, the dirt level in the house, and people's sensitivity to contaminants all affect the frequency of filter replacement.
Wrong Filter
AC filters do not have a universal fit. Ensure you have the right filter that will fit your AC. If in doubt, consult your technician instead of guessing your AC's filter. Filters come in different sizes, and manufacturers usually indicate the size on the filter's frame. Get the wrong filter, and it won't fit snugly.
An improper fit might allow unfiltered air to pass through the sides. The unfiltered air will not only contaminate your indoor air, but it can also clog the AC and affect its efficiency. Read your owner's manual and the size indicators on the filter, measure the filter, and consult an AC technician to ensure you get the right filter.
Damaged Filter
As previously mentioned, the filter works because it traps particles in the air while allowing air to pass through. The filtration is possible because the filter is a mesh or net. The situation can change if the filter suffers mechanical damage.
For example, if something crashes into the air filter, some of the holes might close and restrict airflow. If something bends the air filter, it might leave spaces around its perimeter and allow unfiltered air to flow through. Replacement is the only remedy to a damaged filter.
Wrongly Installed Filter
Lastly, an improperly installed filter can also lead to cooling inefficiency. Filter designs allow air to flow through one side and out the other side for maximum efficiency. Most filters have an arrow that shows the direction of installation. The correct installation is as simple as following the indicated direction.
