Dirty filters are the most common cause of furnace problems. Dust and dirt restrict airflow—and if the filter gets too clogged, the heat exchanger will overheat and shut off too quickly, and your house won't warm up. If the blower is running but no heat is coming out, replace the filter.
Why is my heat not coming on in my house?
Dirty and clogged filters are one of the primary causes of furnace problems and can cause high operating costs. The heat exchanger can overheat and shut off quickly when filters are clogged with dust and dirt. This also causes soot buildup on the heat exchanger, which makes your furnace run less efficiently.
