Change AC Filters Regularly Maintain your home by regularly replacing AC filters to improve indoor air quality, keep HVAC running more efficiently, and help lower energy costs. Unfortunately, many homeowners forget or delay this simple yet crucial maintenance task, leading to reduced airflow, higher costs, or even system damage as a result of missing it altogether.
By following this guide, you will understand why AC filter replacement matters, the optimal frequency for doing it and all necessary steps required for replacement.
Why It Is Important To Change AC Filters Regularly
Your AC filter protects you against dust, pollen, pet dander, mold spores and other airborne particles by trapping dust mites, pollen, pet hair dander and mold spores that enters. Unfortunately, with time the filter becomes clogged; when that occurs: it's no longer effective in filtering airborne pollutants out.
Airflow becomes restricted and inflow becomes limited.
Your HVAC system works harder.
Energy costs continue to skyrocket while indoor air quality declines, both contributing to an increase in monthly energy expenses and decreasing air quality levels.
HVAC components wear out faster.
Filters must move air through them without obstruction to function effectively and may lead to overheating in your system. A dirty filter forces airflow around an obstruction in order to produce cooling performance; thus compromising cooling capabilities and increasing chances of overheating.
How Often Should You Change Your AC Filter?
Frequency depends on many different variables:
Every 30 Days Houses with pets, allergy sufferers and high dust environments; every 60 to 90 Days for heavy AC usage in standard households without pets (with or without AC use); high efficiency or thick media filters should be changed (consult the manufacturer instructions)
Doing a monthly filter inspection is always wise; if it appears gray and clogged it may be time for replacement of an AC filter.
Signs It's Time To Replace Your AC Filter
Keep an eye out for these warning signs:
Reducing dust around the home caused by poor ventilation results in poor airflow from vents, increasing dust levels inside, and potentially decreasing quality of indoor air quality.
Allergy symptoms worsening?
AC running longer than anticipated
Rises in electricity bills could be an indication that your filter could be dirty.
Step-by-Step Guide to Replacing Air Filters (AC Filter Replacement Process).
Switching out an AC filter is quick and painless; taking only minutes.
Step One: Shut Off the AC System.
Before removing the filter from the HVAC unit or thermostat, be sure to switch both off for added safety.
Step Two: Locate Your Filter
To locate the filter, check: Return air vent (RAV), AHU or furnace and system manual as these could all contain filters for you to install.
Step 3: Remove an Existing Filter
Carefully unzip and pull out the filter while noting the airflow direction arrow on its frame.
Step 4: Confirm Filter Size
Each filter's exact dimensions can be seen printed on its side (for instance 16x25x1). Always replace with an identical filter size when replacing an older model.
Step 5: Insert New Filter
Make sure the airflow arrow points towards your AC unit (not towards its vent opening).
Step 6: Restart Your System
Restore power and check for optimal airflow.
Simply change out an AC filter! It is both straightforward and effective.
Select the Correct AC Filter
Not all filters are created equal. Take note:
A MERV rating measures the filter efficiency.
MERV 8-11: Appropriate for most homes.
MERV 12-13 rated HVAC units provide more relief for allergy sufferers.
Higher ratings provide more filtration but may limit airflow if system wasn't designed accordingly.
Follow your HVAC manufacturer's recommendations at all times.
Filter Replacement can bring many benefits when done regularly and effectively. Here are a few advantages associated with regular filter changes:
Altering AC filters regularly is one of the easiest, cost-effective ways to protect both your system and yourself, with improved indoor air quality, lower energy costs, longer HVAC lifespan and cooling performance benefits as well as decreased repair costs. It provides for enhanced indoor air quality as well as decreased energy use - while increasing lifespan, improving cooling performance, lowering repair costs and overall repair expenses for HVAC equipment.
Final Thoughts on Replacing Air Filters
Change AC filters frequently as part of home maintenance to save on energy costs and potential repairs, not only lasting less than 10 minutes but potentially saving hundreds in repairs as well. Clean filters enable your air conditioning unit to breathe freely allowing your home to remain cooler, healthier and more cost efficient.
Make it part of your monthly maintenance regimen to inspect and replace filters as often as necessary - regular upkeep now could prevent serious problems in the future!
