Your furnace filter plays a major role in the efficiency and performance of your furnace. A dirty furnace filter can make your furnace work harder, decreasing it’s efficiency. A dirty filter can even cause your furnace to overheat and shut down as a safety precaution.
Knowing when to change your furnace filter (and actually doing it) can save you some money and some headaches! Depending on your unit and and air filter size, there are different guidelines for when you should change your filter. Andy from Peak Heating & Cooling offers his advice in this blog post.
If you are out shopping for a furnace filter for your Carrier unit, it is important to note that the filter shipped with your unit is made from higher-quality materials than those of the disposable filters found in retail stores. For that reason, replacement Carrier filters can only be purchased through a Carrier dealer. However, keep in mind that Carrier filters are reusable, and can be washed by hand in cold water.
