Summer's Not Over Yet: The Perfect Time to Clean Those Ducts
Still feeling that late-summer sizzle? So is your HVAC system—and it’s dealing with more than just hot air. From the tree-lined neighborhoods near Indian Hills Community College to the peaceful blocks around Wildwood Park, Ottumwa summers come with thick humidity and plenty of AC usage. But while your system’s been working hard to cool the air, it’s also been quietly collecting dust, allergens, and moisture in the process.
August is that sweet spot where it’s still hot enough to run your AC, but just ahead of the seasonal shift toward cooler temps. It’s the ideal time to schedule a professional HVAC cleaning. You’ll boost your system’s efficiency, cut down on energy bills, and breathe easier with cleaner indoor air. And with Iowa’s weather swinging from muggy to freezing in a heartbeat, your HVAC system needs to be ready for anything.
So, what’s actually going on inside your HVAC system? And how often should HVAC ducts be cleaned to avoid problems down the road? Let’s get into it.
How Your Home’s HVAC System Works
Your HVAC system is more than just a switch on the wall. It’s a full network of parts working in harmony.
- Furnace and AC units heat or cool the air
- Air handler and evaporator coil move the air along
- Ductwork, filters, and vents circulate the air from room to room
Here’s the flow:
- Fresh air is pulled in.
- It passes through a filter (hopefully not clogged!).
- It’s cooled or heated and pushed through the ducts.
- Exhaust air heads outside.
Imagine that the airflow is constantly picking up dust, pollen, and pet hair, then blowing it back into your living room. Not exactly the kind of air you want to be breathing in, right?
Where Dirt Hides in Your HVAC System
Let’s talk about the usual suspects:
- Air Filters: Your system’s first line of defense. They clog fast though, especially if you’ve got furry friends.
- Ductwork: Moisture from our humid Ottumwa summers turns these into the perfect mold hideouts.
- Coils: All that condensation is a mold magnet.
- Vents & Registers: Dust loves to settle here, choking airflow and spreading grime.
Left unchecked, this buildup can hurt your system’s efficiency and spread allergens fast.
What’s Lurking in Your Air? Mold, Dust, Pollen & Pet Dander
Every time your HVAC system runs, it pulls in particles from outside and from inside your home. In Ottumwa, that could mean:
- Farm dust (it travels farther than you think)
- Pollen from our lush green spaces
- Mold spores from old homes or past water damage
- Pet dander, especially if your four-legged family members like lounging near vents or rolling around on rugs
These contaminants irritate allergies, worsen asthma, and make your home feel stale. Add in moisture in the ducts, and you’ve got the perfect breeding ground for mold.
How Often Should You Clean Your HVAC Ducts?
We hear it all the time: how often should HVAC ducts be cleaned?
Here's the breakdown:
- Every 3–5 years for the average home
- Every 2 years if you’ve got pets, allergies, or smokers in the home
- Every year if you’ve dealt with mold, water damage, or an especially dusty setup
A clean system protects your HVAC investment. A clogged system works harder, costs more to run, and wears out faster.
Why August Is HVAC Cleaning Season in Ottumwa
Think of it as your pre-fall tune-up. This is why HVAC cleanup at the end of summer makes sense:
- Humidity’s been stewing in your ducts all summer—prime time for mold to grow.
- Kids are heading back to school, and air quality matters more when your home becomes a weekend-only hub.
- Cooler temps are coming, and you’ll be cranking up the heat soon. Don’t wait until that first frost to find out your system’s struggling.
August is your window to act before the cold hits Ottumwa hard.
