Filters: When to Change Them & How
04/08/2024
Welcome to the ‘How-To’ guide for all things filters, whether it be needing to know when you are supposed to change them or you have no idea on the how. This blog is here to help answer both of those problems, making it so you can do it without needing a technician out. Below are two pictures of a dirty filter(LEFT) and a new filter(RIGHT):
First up: WHEN
The ‘when’ portion of this blog is less of a definite time and more of a how to determine when you should change it. Just remember that every household could be different, it all just depends on the factors.
- Check Monthly
- Filter Type
- Visible Dirt
- Household Factors
- Seasonal Changes
You should try to inspect your filters monthly, especially during peak seasons like summer and winter
Different filter types have varying lifespans, follow manufacturer guidelines or what is already in your system if you haven’t had previous problems
If your filter looks dirty or clogged, it’s time for a replacement regardless of the time frame
Take factors like pet hair, allergies, and indoor air quality into consideration. Homes with pets or allergy sufferers may require more frequent changes
Pollen, dust, and other airborne particles can increase during certain seasons, resulting in possible frequent filter changes
Finally: HOW
The ‘How’ might be the part that keeps people from doing it themselves, which is fine.
There are times where having a professional out is just easier.
- Turn Off System
- Locate Filter
- Remove Old Filter
- Insert New Filter
- Secure
- Turn On System
Shut off your HVAC system to prevent debris from circulating during the replacement process
Find the filter compartment, it’s typically near the return air duct (the ductwork coming off side of furnace) or air handler
Take out the old filter carefully, noting its orientation for proper replacement
Slide the new filter into place, ensuring it’s facing the correct direction according to the airflow arrows
Close the filter compartment securely, ensuring there are no gaps where air could bypass the filter
Once the new filter in installed, turn your HVAC system back on and monitor its performance
The regular filter changes improve indoor air quality, enhance system efficiency, and prolong the lifespan of your HVAC equipment. You can use this to teach yourself on how to change the filters yourself or when you have one of our technicians out for your yearly preventative maintenance, they can check and change your filters for you!
