Not changing your air filter can have serious consequences for your home and your health. A dirty filter reduces airflow to the HVAC system, making it work harder and use more energy, which costs you more money. You may also be unable to keep your home at the right temperature. This means that it may need to work for longer periods, making the system difficult.
If the air filter is clogged and can't trap contaminants like it used to, those things can go back to the air that everyone in your home breathes. Immediate problems may include headaches, itchy eyes or throat, and dizziness. If the air filters are not changed and problems persist, the long-term effects could be respiratory disease, heart disease, or cancer. The danger of not changing the air filter in the house for a long time is that it will eventually lead to damage to the oven.
This means that the entire system will be destroyed by excess heat. Getting the most value out of your home can be as easy as changing air filters. Homeowners who ignore filters in their heating and air conditioning systems risk increasing energy costs, damaging expensive equipment, and decreasing indoor air quality and personal health.You will no longer be able to filter the air properly, allowing dust and contaminants to enter the HVAC system. If you have more than one cat or dog, or if you have chronic allergies or asthma, it's generally recommended to change your air filter every 20 to 45 days.
As air moves through a building's HVAC system, air filters trap and pick up large and small particles, such as dust, allergens and microorganisms. While the filter is designed to accommodate these tiny elements, the buildup creates a nearly impenetrable barrier so that air cannot fully flow, which can ultimately cause multiple problems for the entire HVAC system. So “How often should I change my oven filter? This is a question that many homeowners ask and the answer depends on several factors. The more people who live under your roof, the more often you'll need to change your air filter, so be sure to check it often. In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. While it is possible to operate the system without a filter in the air conditioner, HVAC experts do not recommend it at all.
If you have a higher efficiency filter and don't change the AC filter often enough, a buildup of moisture can cause mold to build up in the ducts, leading to serious mold infestations. If you find that old filters look like nothing, not even air, could pass through them, it's time to contact an HVAC professional.
