Furnace Filter Refresh

Updated: Nov 1, 2022

Replacing your furnace filter each season.

The furnace filter is a key part of your HVAC system and plays an important role in maintaining the efficiency of the entire system. If you don't replace your filter regularly, dust, dirt and other harmful particles can build up inside it. This can reduce airflow through your home, causing everything from mild discomfort to serious problems with heating or cooling your home.


The best time to replace your furnace filter is during the spring and fall.

The best time to replace your furnace filter is during the spring and fall.

This is because these seasons are when your home's air conditioning system will be operating at full capacity, which means more dust particles will enter into your home. If you're lucky enough to have a ductless central system that uses an oscillating fan as part of its cooling mechanism, then you'll want to make sure that this fan is running at max speed when it's time for replacement.

If you don't have such a system installed in your home, then there are still ways of keeping things relatively clean while using this method: use an ozone generator or HEPA vacuum cleaner with high-efficiency particulate air (HEPA) filters on the outside of their exhaust port; keep pet hair off furniture surfaces; remove carpets where possible - especially those near baseboards; use masking tape so no one gets sick from airborne particles coming from anywhere besides their mouths!


You should replace your filter every 90 days, or more often if your home is dusty.

The average furnace filter should be replaced every 90 days, or more often if your home is dusty. If you change your filters too often and they are still dirty, then there may be dust buildup on the inside of your furnace that prevents it from heating properly.

You can tell if it's time for a new filter by looking at the outside of your unit: if it looks dirty or grey in color, then that means you need a new one! Also check to see if there are any signs of mold growing inside—this could be an indication that something harmful is growing inside as well!


To check if your filter needs replacement, hold the filter up to a strong light. If you can't see through it, it's time to replace it.

If you can see through the filter and there are no visible debris on its surface, clean them with a damp cotton ball or paper towel and let them dry before replacing the furnace filter in your home’s furnace vent.


When replacing your filters, write the date on each filter so you know when they have been replaced.

When replacing your filters, write the date on each filter so you know when they have been replaced. You can use a permanent marker or calendar to keep track of the dates.

If you have a spreadsheet program like Microsoft Excel, one way to track this information is by creating columns for each season and then entering each filter into that column accordingly. For example: "Season 1 - Filtration A", "Season 2 - Filtration B", etc...

If you don't want to spend money on an expensive label maker (like I do), there are some other options out there too! For example: take dry erase markers and write “Season 1” above them; then take another dry erase marker and write “Season 2” above them; then take another dry erase marker and write “Season 3” above them...and so on until all the filters have been replaced in chronological order!


It is important to maintain a good furnace filter to keep your HVAC system operating efficiently, and because of its effect on improving indoor air quality.

The furnace filter is the most important part of your HVAC system. It's responsible for filtering out dust, pollen, pollen dust and other harmful pollutants from entering into your home.

Furnace filters can improve indoor air quality by up to 90%, which means you will have cleaner air in your house and less asthma attacks or respiratory problems caused by poor indoor air quality.

A dirty furnace filter can lead to poor airflow through your HVAC system as well as clogging up vent pipes with debris that collect on them over time.


Conclusion

Replacing your furnace filter is an essential task that you should do on a regular basis. The best way to know when it's time to replace your filters is by following the steps outlined above, but if you have any questions or concerns about this process, please contact us.
