This isn’t just a cooling issue. It’s a moisture problem. And if you ignore it, it can lead to mold, poor air quality, and even higher energy bills.
Here’s what’s causing that sticky air, and how Petitt Heating & Cooling can help fix it.
What Causes That Sticky Feeling Indoors?
When the air inside your home holds too much moisture, it creates that warm, heavy feeling, even if your thermostat says it’s cool.
Here’s how it happens:
- Oversized AC units cool the air too fast and don’t run long enough to remove moisture.
- Poor ventilation traps humid air inside your home.
- Crawl space or basement leaks let moisture rise into your home.
- Older or undersized systems are unable to remove enough humidity while cooling
Signs You Have a Humidity Problem
Watch out for:
- Sticky air
- Foggy windows
- Musty smells
- Mold spots
- Allergy flare-ups
If this sounds all too familiar, your AC might need some backup.
Tip #1: Install a Whole-Home Dehumidifier
Your air conditioner removes some moisture, but in Tennessee’s climate, it usually isn’t enough. A whole-home dehumidifier pulls excess moisture from the air before it circulates through your home.
Benefits include:
- Drier, more comfortable air
- Less mold and mildew risk
- Improved indoor air quality
- Reduced strain on your HVAC system
At Petitt Heating & Cooling, we specialize in installing high-performance dehumidifiers tailored to your home’s needs. You’ll feel the difference within hours.
Tip #2: Improve Your Ventilation System
Upgrading your ventilation will:
- Improve air circulation
- Remove trapped moisture
- Balance airflow across rooms
Proper ventilation helps eliminate trapped humidity and improves overall indoor air quality.
Tip #3: Encapsulate Your Crawl Space
It happens by:
- Sealing gaps and vents
- Installing a vapor barrier
- Adding insulation and moisture control
Petitt Heating & Cooling offers full encapsulation services to keep your home, which is especially important in older homes.
