Many folks in Sheboygan County associate their furnace with winter, and rightly so. But did you know your furnace filter works year-round, even during those warm summer days on the lake? Whether you live in Plymouth, Kohler, or right here in Sheboygan, it’s important to understand how this small piece of equipment can impact your home’s comfort and air quality, even when your heat isn’t running.
Why Your Furnace Filter Matters in Summer
Even if your furnace isn’t producing heat during the summer, your HVAC system is still in action. That includes your central air conditioner. Most homes in our area use a combined system that shares ductwork between heating and cooling. The furnace blower (the fan that moves air) runs every time your air conditioner turns on, and every time that fan runs, air is pushed through the furnace filter.
This means your filter is still collecting dust, pet dander, pollen, and even mold spores, all common during Sheboygan’s humid summers. If the filter gets clogged, it can strain your air conditioning system, making it work harder and costing you more on your electric bill.
Signs Your Filter Needs Changing
Here are a few common signs that it’s time to change your furnace filter this summer:
-
You’re sneezing more often indoors – Summer allergens like pollen are high in July and August.
-
Your house feels stuffy even when the AC is on.
-
Dust builds up quickly on furniture or vent covers.
-
Higher-than-normal electric bills from your AC working harder than it should.
Even if you don’t notice these signs, it’s a good idea to check your filter every 30 to 60 days—especially during the summer.
Benefits of Changing Your Filter in Summer
Changing your furnace filter is a simple task with big benefits:
-
Improves indoor air quality – Especially helpful for those with allergies or asthma.
-
Keeps your home cooler – A clean filter helps your AC run efficiently.
-
Extends the life of your HVAC system – Less strain means fewer costly repairs.
-
Reduces energy use – A dirty filter makes your system work harder, raising utility bills.
For older homes common in Sheboygan neighborhoods like Riverdale or South Calumet, newer filters can help keep dust from older ductwork out of your living space.
What Kind of Filter Should I Use?
Not all furnace filters are the same. If you’re unsure what type your system needs, the team at Trilling True Value Hardware can help you find the right size and MERV rating (that’s the filter’s ability to catch tiny particles). For summer, a basic filter changed regularly works just fine for most households. If you have pets or health concerns, a higher-grade filter might be better.
When Should I Change It?
Set a reminder to check your filter at the start of each month. In the warmer months of June, July, and August, Sheboygan can experience high humidity and pollen counts. That’s when your filter works hardest. If it looks gray, dusty, or clogged, it’s time to swap it out.
Keep It Simple: Set a Summer Filter Routine
You don’t need to wait until winter to think about your furnace. By making filter changes part of your summer home care routine—like tending your garden or checking your smoke detectors—you’ll breathe easier all season long.
