Homeowners should generally replace their furnace filter every few months, but there’s more to consider that impacts frequency. Depending on the circumstances, you may need to change your filter more often. A filter has a massive impact on the integrity of your heating and cooling equipment and indoor air quality.
A furnace filter serves several purposes, but its primary job is to help protect interior components from debris. This includes dust, pollen, pet dander, and mold spores. It also helps prevent debris from circulating throughout your indoor air, which is particularly beneficial for allergy sufferers.
An accumulation of debris reduces airflow, which could lead to significant issues, such as decreased efficiency. It may also result in component strain, unexpected breakdowns, and an increase in problems. This leads to frequent repairs and a shortened system lifespan. Changing the filter is a much easier and more cost-effective solution than paying for expensive repairs or replacing the unit prematurely.
There are several types of furnace filters, but fiberglass filters are usually what you’ll find in residential HVAC systems. Out of all the filter types, they’re usually the most affordable option upfront. A couple of the other types of filters include polyester filters and pleated filters.

You should typically change your HVAC filter every 30 to 90 days. However, the frequency at which you need to replace it depends on several factors. For example, you should change it more frequently if there are health-compromised individuals, kids, pets, or allergy sufferers in the home. Generally, homes with pets may need to replace the filter more frequently due to the prevalence of pet fur and dander.

The most important thing you should do before changing your furnace filter is to shut your unit off. If you leave it running while changing the filter, debris can enter the system and cause problems. Remove the filter carefully from the system. When you’re pulling out the old one, take note of how it was positioned. This will give you direction for installing the new filter. Turn the system back on and look for any possible issues, such as unusual noises. If there are any, turn the system back off, take the filter out, reposition it, and turn the unit back on. If problems repeat, turn your system off again and don’t attempt to use it until our team can determine what’s happening.
You should call a professional HVAC technician if you attempt to replace a furnace filter and your system behaves abnormally afterward. For instance, unusual sounds, such as banging, could indicate an issue. It may have to do with the filter itself or with another area of the furnace. A burning smell may indicate you’ve allowed some debris to enter your system. The smell should go away quickly. If not, reach out for assistance. If you don’t feel comfortable changing the filter or you can’t do so safely, you can also call us for expert assistance.
It’s a good idea to do a basic self-inspection of your furnace while you’re changing the filter. Look for obvious signs of trouble like leaks or corrosion. If you spot issues, you shouldn’t wait until your next furnace maintenance appointment to address them. HVAC problems don’t improve on their own and usually require professional assistance to rectify the situation.
You especially shouldn’t delay scheduling professional support if the problem seems serious. For example, a yellow burner flame or pilot light instead of a blue one may indicate incomplete combustion that can generate carbon monoxide. This could be a serious safety hazard that requires immediate HVAC assistance. Even filter issues benefit from prompt professional attention.
There are certain factors that can cause your filters to get dirty more quickly. Some include having pets, smoking indoors, dusting irregularly, cooking, and using a fireplace. Leaky ductwork may also be an issue. It can allow an incredible amount of dust and debris from areas like basements and attics into your HVAC system. Changing indoor habits and having a professional repair your ductwork are two important ways to prevent your filters from clogging fast.
