Not changing your air filter can have serious consequences for your furnace. Without a new air filter, the oven will overheat every time it is turned on again. This is known as short cycling. Dirty oven filters cause the oven to work harder than due to decreased airflow.
The harder your oven works, the faster your parts will wear out and need repairs. If the air cleaner is not serviced often enough, it will eventually become clogged to the point where air cannot pass through it. When the oven is operating, the lack of air flow will trap heat in the system. As the temperature inside the system continues to rise, the limit switch will turn the oven on and off to prevent it from overheating.
This will temporarily mitigate the problem, but will not resolve the root of the problem. 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. Air filters typically have a MERV (Minimum Efficiency Report Value) that determines the type and size of contaminants against which the filter will act.
The filter is installed in the return duct, so that all the air that flows into the oven must first flow through the filter. 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. This clearly indicates that the air filters are clogged and should be replaced as soon as possible. The Minimum Efficiency Report Value (MERV) rating for an air filter measures how effectively the filter prevents dust and other contaminants from passing through the filter into the air stream. However, some older models have air filters inside them and you may need to have the right tools to replace them.
In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. Remember, replacing air filters costs less than $50, so don't let delay and negligence cost you thousands of dollars. If you forget to replace your air filter for an extended period of time, there are often devastating results. The only type of filters that trap allergens and spores are HEPA, or high-energy particulate air filters. You'll notice some dust around the HVAC unit or in your home if you don't change the central air filter. But what happens if you let that time go by a little? Before we talk about WHEN you should change your air filter, let's start with the WHY.
It can cause a total breakdown if your system is working too hard to move through blocked air filters. You can hear it: Your HVAC technician is giving you lessons on how to make sure you change your air filter. It's important to note that there are high-efficiency filters that are designed to filter out small bacterial, mold, and fungal particles, but your standard MERV 8-11 filters will simply block out larger particles of dust, dirt & hair. The consequences of not changing your furnace's air filter can be severe. Not only does it lead to higher energy bills due to increased strain on your furnace, but it can also cause damage to expensive equipment and decrease indoor air quality and personal health.
Furthermore, if left unchecked for too long, it can even lead to a total breakdown of your furnace system. It's important to remember that replacing an air filter costs less than $50 - so don't let delay and negligence cost you thousands of dollars! Make sure you change your furnace's air filter every 90 days or 3 months for optimal performance.
