Air filters often clog or block, hindering the normal functioning of an HVAC system.
To avoid this, you should change the air filters at least once every three months.
Neglecting your filter can cause severe damages to your system that would lead to premature wear and tear. Air filters are made of pleated paper or spun fiberglass and enclosed by a cardboard frame. They are positioned in specific places in your HVAC systems to act as barriers that prevent contaminants and other particles such as pollen, dust, mold, lint, and bacteria from circulating in your indoor air or from entering sensitive parts of your system. When you neglect an air filter, it gets clogged by particles and contaminants that accumulate over time. This build-up then creates an almost impenetrable barrier that impedes proper airflow and consequently causes several problems for your HVAC system. The first problem that you will experience is higher energy bills. When proper airflow in your system is restricted, your entire HVAC system works harder to deliver air and heat where it is needed, increasing your energy bills. The HVAC system will not regulate your home’s indoor temperature properly. Since your system will have difficulty in distributing air and heat adequately, some of your rooms could end up too cold or too hot. Dirty air filters can lead to health problems as they cannot effectively trap contaminants, which might end up circulating in the air you’re breathing. Issues such as itchy eyes or throat, headaches, and dizziness may then arise. You may also have clamped-up coils if they are overworked due to dirty air filters. Air won’t flow over the coils adequately, resulting in total system failure. Clogged air filters place undue strain on your HVAC system as it has to work harder to be effective.
