Humidity vs Your House: What Late-Summer Moisture Does to Your Comfort (and Your Wallet)

Why does my house feel like a sauna in August?

If you’ve ever walked into your living room during a late Iowa summer and felt like you just stepped into a tropical rainforest, you’re not imagining things. Humidity has officially moved in, taken over your space, and refuses to pay rent.

This time of year, it's not just the high temperatures making you uncomfortable, it’s the moisture in the air, also known as the real MVP of household stickiness and bad hair days. And yes, we’re looking at you, corn sweat — that weirdly gross but totally real phenomenon where acres of sweet Iowa corn release moisture into the air, making it feel even more humid. (It’s like the corn is sweating right along with you.)

What does all this moisture mean for your home?

Late-summer humidity doesn’t just make you feel clammy and crabby. It can wreak havoc on your house and your comfort:

• Sticky floors and furniture
  Ever noticed your wood floors start to warp or your doors stick a little more? Moisture is likely the culprit.

• Musty smells
  That “basement smell” can creep into your living space when humidity levels stay high. Nobody wants eau de mildew.

• Higher energy bills
  When your A/C works harder to remove moisture and cool your home, your energy bill skyrockets faster than a State Fair ride.

• Mold and mildew growth
  Excess moisture is a party invitation for mold spores. Once they show up, they bring friends, and suddenly you’ve got a real problem on your hands (and your walls).

What can you do about it?

Here’s how to kick humidity to the curb, and take your comfort (and sanity) back:

• Install or upgrade your dehumidifier
  A whole-home dehumidifier works alongside your A/C to maintain balanced humidity levels, especially during peak corn sweat season.

• Keep your A/C properly maintained
  A clean, efficient system pulls moisture out of the air more effectively. If yours is overdue for a checkup, we know a guy (hint: it’s us).

• Ventilate smartly
  Use exhaust fans in bathrooms and kitchens, and make sure your attic is properly ventilated. Moisture has a way of creeping into the least convenient places.
