Changing air filters in autumn is an excellent idea and part of good seasonal maintenance, particularly for homes with HVAC systems. Here’s why and how you should approach it:
Why You Should Change Air Filters in Autumn:
Improved Air Quality: After summer, allergens like dust, pollen, and mold can accumulate in your air filters. By replacing them in autumn, you’ll ensure better indoor air quality as you start spending more time indoors.
Optimal HVAC Efficiency: Clean air filters improve the efficiency of your heating system. Clogged filters force your HVAC system to work harder, which can lead to higher energy bills and even wear out the system faster.
Prepare for Cooler Weather: As you transition from using air conditioning to heating, it’s crucial that your system works efficiently. Fresh filters prevent strain on the system when it needs to heat your home.
Prevent Allergies and Illness: Autumn often brings an increase in respiratory issues like allergies. A new air filter can reduce dust, mould spores, and other airborne irritants, promoting better health during colder months.
Steps to Change Your Air Filter:
Turn Off the HVAC System: Before changing the filter, turn off the heating or air conditioning to avoid dust and debris getting into the system.
Locate the Air Filter: Check the HVAC unit or vents. The filter is often located in the return air duct or inside the air handler.
Check Filter Size: The filter size is usually printed on the edge of the old filter. Make sure to purchase a replacement that matches the size.
Remove the Old Filter: Carefully slide the old filter out of its slot. Be cautious not to disturb dust or debris that might have accumulated.
Install the New Filter: Insert the new filter with the arrows pointing in the direction of the airflow (usually toward the HVAC unit).
Turn the System Back On: After installing the filter, turn the system back on and make sure it’s running smoothly.
Frequency of Replacement:
In the Autumn/Winter, it’s recommended to replace air filters every 1–3 months, depending on your home’s air quality, the type of filter, and the presence of pets or allergies.
Filter Types to Consider:
- Fiberglass Filters: Cheap but less effective at trapping small particles.
- Pleated Filters: Slightly more expensive but more effective in capturing smaller particles like dust mites and pet dander.
- High-Efficiency Filters (HEPA): Ideal for those with severe allergies or respiratory issues, though these can sometimes be too restrictive for some systems.
Changing air filters in autumn keeps your home comfortable and your HVAC system running efficiently during the colder months ahead.
