Without a new air filter, the furnace will overheat every time it is turned on again. This is known as short cycling. Dirty furnace filters cause the furnace to work harder than necessary due to decreased airflow. The harder your furnace works, the faster its 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 furnace is running, 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 furnace on and off to prevent it from overheating. This will temporarily mitigate the problem, but will not resolve the root of the problem.If the air filter is clogged and can't trap contaminants like it did before, 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.

Furnaces are very important, but if not properly maintained they can become dangerous, and this can be the case if the filter inside is old.
