The furnace is among the most important appliances in your entire home as it ensures that your property can remain warm during the coldest months of the year. One of the most common forms of routine maintenance that needs to be done for your furnace is to replace your filter. In general, most people will want to change their filter every 90 days, but this could vary based on a variety of factors.
Pets in the Home
One factor that will influence how often you need to change your furnace filter is whether or not you have pets in the home. If you are an owner of a dog, cat or other animal that can shed, the furnace filter can clog much faster. In these situations, you likely will need to replace it much sooner. You should check the filters at least once per month and replace it when it appears clogged
Issues With Allergies
Another situation in which you may need to replace your furnace filter more often is if you have issues with allergies. Those who have allergies to mold, dust or pet fur should plan on replacing their filter more frequently. By replacing it as often as every 30 days, you can drastically reduce the accumulation of debris. This can then reduce your sensitivity.
Quality of Your Furnance Filter
Additionally, you may need to replace your filter sooner due to its quality. At a standard hardware store, you will find that there are many different types of filters available. They are made from various materials and have different layers of filtration. An HVAC technician from Baltimore's best HVAC company - SuperTech Heating & A/C - can help you figure out which filter is right for you. It is important to read the instructions on each to ensure you know the recommended replacement schedule. If you'd like a more extensive guide to filter changeouts, we have an entire blog about them!
