Since clogged air filters make the system strain to create airflow, warm or cool air cannot go where it is needed. This means that some rooms could be too cold during the winter or too hot in the summer.
If the air filter is clogged and cannot trap contaminants as it did before, those things can end up back in the air that everyone in your home is breathing. Immediate issues could include headaches, or itchy eyes and throat. If the air filters are not changed and the issues continue, the long-term effects could be even lead to respiratory disease.
As the system is working harder to get around clogged air filters, it can cause the entire system to overwork and eventually break. If this happens, you’ll need to replace the entire system. Air filters are so much easier to replace compared to replacing the entire system.
Evaporative coils, which help remove heat from the air to keep your home cool, can freeze up if they are overworked. With a clogged air filter, the air won’t flow over the coils correctly, which makes them stop working and leads to total system failure. Protect your HVAC system and your wallet and change your air filters on a regular schedule.
