Having a filter in your furnace is essential for maintaining good air quality in your home. Without a filter, dust and particles can fly through the ventilation grilles and into the air, reducing the overall air quality. Not changing the filter regularly can also lead to clogging, which can cause a variety of problems for your HVAC system. These include system inefficiency, higher energy bills, inadequate air quality, and ultimately failures.
When the oven is operating without a filter, the lack of air flow will trap heat in the system. This will cause the limit switch to turn the oven on and off to prevent it from overheating. This is known as short cycling and is only a temporary solution. Without a new air filter, the oven will overheat every time it is turned on again.
There are many different types of filters to choose from and a professional can recommend one that works more efficiently and filters out certain details that others can't. Disposable filters usually have a flimsy cardboard frame, while filters with a plastic frame are usually reusable. Slide the filter into place, making sure that the arrows in the frame point in the same direction as the previous filter. An oven filter serves as a barrier to trap dust and debris entering the return duct from reaching the fan.
A well-maintained oven will also perform more efficiently and effectively than one that works despite clogged filters or other problems. If there is no filter to provide that protection, the inner workings of your oven can be covered in dirt. An overworked oven can easily overheat and break down, so inserting a new, clean air filter regularly will help protect the integrity of your unit. The purpose of an oven air filter is to keep your HVAC system in perfect condition, especially the fan motor and evaporator coils.
For example, running an oven without a filter overnight isn't likely to cause problems, but you should never allow this to become a long-term solution. Having an air filter in your furnace is essential for maintaining good air quality in your home and keeping your HVAC system running smoothly. It's important to change your furnace filter regularly to ensure that it's working properly and not causing any issues with your heating system. Fortunately, these filters are easy to change, making it a quick and painless household maintenance task that dramatically improves oven airflow.
