When it comes to air filters, they require routine maintenance and replacement similar to other machinery. A clogged air filter can lead to pollutants making their way through the air. Even further, furnace filters can be dirty and go unnoticed for some time. These are some common symptoms of a clogged air filter that everyone should look for to know when it is time to replace a dirty air filter.
1. Keep an eye on that energy bill
When a home air filter is clogged, the air unit has to work extra hard to pump air into the home. This will consume more energy and drive up an energy bill quickly. If an energy bill looks unusually high during a given month, this could be a sign that the air filter should be replaced.
2. The home temperature won’t drop
Air filters need to be clean to allow an air conditioner to function properly. If an air filter is clogged, the pollutants will block the flow of air into the home. This will prevent the air conditioner from cooling the home. If the air conditioner is turned all the way up and the temperature still won’t come down, it could be time to replace the air filter.
The machine runs a risk of overheating when the system has to work extra hard to cool the air. Similar to working a car engine too hard, the air conditioner has to dissipate the heat it collects while cooling down the air. If the system has to work too hard, it will shut down for safety reasons. Listen for the air conditioner cycling between on and off settings frequently. If the home remains warm despite this cycle, the system is likely overheating. It is
time to check the air filter.
4. Look at the evaporator coil
This is the portion of the air conditioner that absorbs the heat that is removed from the air when it is cooled. If the air filter is clogged, the heat cannot reach the evaporator coil. Go to the air conditioner unit and take a look at the evaporator coil. The coil might be frozen due to the inability of the heat to reach the evaporator coil. A common cause of this is a clogged air filter. So, it might be time to replace it.
5. Allergies start acting up
The air filter’s job is to keep the air clean. Many people with allergies struggle with extra dust or other pollutants in the air. If those around you start sneezing more or complaining about their allergies, check the air filter. It might be clogged.
