Clean air filters are as essential on your furnace as they are on your car. They can filter out pollen and dust and need to be cleaned or replaced as recommended by the furnace manufacturer. Filters should be checked monthly during the heating season and the cooling season if you have air conditioning.
It is also a good idea to locate a Carbon Monoxide detector badge at the furnace to monitor its safety. See my tutorial How To Test for Carbon Monoxide for reference.
