What Happens If I Don't Change My Air Filter?

Before discussing what happens to your AC unit when filters are not changed regularly, it is prudent you first understand a few things about air filters. An air filter is an essential part of your AC unit that traps dirt and airborne contaminants from the air entering your house protecting both your family and HVAC system. But where do those trapped particles go?  They build up on the air filter with time. So, the longer the air filter stays installed, the more particles it collects, and the less amount of air flows. Eventually, it is likely that your air filter will clog making it almost impossible for your AC unit to push air. You may end up needing to contact an HVAC repair technician due to potential damages.
If you don’t change your air filters regularly, then the following is bound to happen:

1.    Increased energy consumption. Your AC unit relies heavily on the cooling unit’s blower fan, the heating performance and circulation of air that can impact the amount of energy consumed. Meaning that if the blower fan works harder than usual when drawing air, it will be reflected in your higher energy bills. According to the US department of energy, a clogged air filter may use up to 15% of extra energy. Note that just as the inefficiency increases so do your energy bills until you either call your HVAC repair technician or you service the unit.

2.    Frozen evaporator coils. In case your filter clogs during the cooling summer season, it can make the cooling coil or the evaporator to freeze up. Reason being that only a small volume of air goes past the coil to dispel condensation produced during the freezing process. Lack of enough airflow makes this condensation to cool – reducing the system’s capacity to remove the heat from the air and cool your home. It causes you to get an HVAC repair guy to service your AC unit eventual breakdown.

3.    Inadequate cooling/heating. If your filter becomes clogged with a lot of dust, debris, and dander, then you are likely to experience cold and hot spots in your residence; because your blower fan is not able to efficiently and effectively pass the air. According to the Florida Public Service Commission research findings, the second cause of increased energy bills during the summer was the clogging of air filters. If you detect that anomaly, you should contact an HVAC repair professional.


4.    Unhealthy Air. Contacting your HVAC repair professional may not be enough if air with debris and dust is circulated in your home. Why? Because chronic allergies associated with respiratory and asthma conditions may arise forcing you to contact your family doctor. Worse still, if you keep a lot of chemicals in your house, or you own pets, the indoor air quality may impact your health negatively over time. Remember all that can happen if your air filter is clogged or serviced by an HVAC repair technician.

5.    Furnace failure. According to Diamond Certified Organization, clogged air filters are the leading cause of AC unit failure as they make heaters stop. Getting an HVAC repair technician to change your clogged air filter may not be a bad idea considering that if you change it improperly, it can damage the other internal components of your AC unit.
