HVAC Tips for Wytheville, VA Homeowners
Is your air conditioner not cooling like it used to? A dirty air filter might be the culprit—and it’s one of the easiest things to fix. In fact, knowing when to change your AC filter can save you money, keep your home more comfortable, and even extend the life of your air conditioning system.
Here in Wytheville, where summers can be hot and humid, your AC works overtime. Let’s take a closer look at how often you should replace your filter and why it’s so important.
Why Changing Your AC Filter Matters
Your AC filter traps dust, pollen, and debris before it can circulate through your HVAC system and into your home. But when that filter gets clogged, it restricts airflow. That makes your system work harder—and that means:
- Higher energy bills
- Uneven cooling
- Reduced indoor air quality
- Risk of system breakdowns
According to the U.S. Department of Energy, replacing a dirty filter can lower your AC’s energy use by up to 15%.
How Often Should You Replace Your Air Filter?
For most homes, you should replace your air filter every 30 to 60 days—especially during the cooling season.
But your ideal schedule may depend on a few factors:
- Homes with pets- Every 30 days
- Allergy sufferers- Every 20–45 days
- No pets/allergies- Every 60–90 days
During Wytheville’s summer months (June–August), we recommend checking your filter at least once a month due to higher AC usage and increased outdoor allergens.
Signs Your AC Filter Needs Replacing
Not sure if it’s time to change your filter? Look for these common warning signs:
- Weak or reduced airflow from your vents
- AC takes longer to cool your home
- Dust building up around vents or furniture
- Filter looks gray or clogged
- Higher-than-usual energy bills
If you notice one or more of these, it’s probably time for a replacement.
How to Find and Replace Your AC Filter
Replacing your air filter is a simple task any homeowner can do. Here’s how:\
- Turn off your system.
- Locate the filter. Most are found in return vents or near the HVAC blower unit.
- Slide out the old filter and check its size (printed on the edge).
- Insert the new filter, making sure the airflow arrows point the right way.
Pro tip: Choose a pleated filter with a MERV rating of 8–13 for better efficiency and filtration.
Why Wytheville Homeowners Should Be Extra Diligent in Summer
Southwest Virginia summers come with high pollen counts, dust from rural areas, and plenty of humidity. All of these can cause filters to clog faster.
