It is wise to change your furnace filter and air conditioning filter at least every 3 months. Ideally, you should be changing your filter every month and never waiting more than 3 months to change your furnace filter. One of the most effective ways to enhance the quality of air in your home is to change your furnace filter.

The filter captures airborne particles such as pollen, mold spores, pet dander and viruses. There are many other problems caused by dirty air filters like allergies, asthma and the dreaded itchy face. Most of these aren’t serious problems but an annoyance which can be easily prevented.

Make sure you check your air filter on a monthly basis to ensure it is still clean. If you hold the filter up to a light and can’t see through it, time to get a new filter. If dust and dirt fall out of the filter the moment you pick it up, time to get a new filter. The next time your Viking Heating and Cooling technician is out to perform a Chicago furnace tune up or AC tune up, ask him to show you how to install your air filter if you are unsure how. You can also ask about any filter options you have in order to get more out of your filter than you expected.
