How to Reduce Humidity in Your St. Louis Home During Hot Months. St. Louis summers bring more than just high temperatures—they bring relentless humidity. That heavy, sticky feeling in your home isn’t just uncomfortable; it’s a sign that excess moisture is making your living space less healthy, less efficient, and more prone to damage.

Many homeowners rely on their air conditioner to handle humidity, but the truth is, while ACs do remove moisture, unless your system features inverter (variable capacity) technology, it wasn’t designed for optimal humidity control in all situations. Instead, they focus on cooling, which can leave your home feeling clammy.

The real solution? A whole-home dehumidifier from AprilAire, expertly installed by SmartHouse.

Blog Summary

  • High humidity makes your home feel hotter, damages wood, and promotes mold growth.
  • ACs aren’t designed to fully control moisture, leading to clammy indoor air.
  • An AprilAire whole-home dehumidifier removes excess moisture through your HVAC system.
  • Improves air quality, lowers cooling costs, and prevents structural damage.
  • SmartHouse provides professional installation, ensuring a drier, more comfortable home.

How High Humidity Affects Your Home and Health

Excess humidity does more than make your home feel warmer. It creates a breeding ground for mold, pests, and structural damage, all while driving up energy costs.

  • Increases health risks – Dust mites, mold spores, and bacteria thrive in humid conditions, triggering allergies and asthma. If you frequently wake up congested, experience lingering odors, or notice an increase in allergy symptoms, humidity could be the culprit.
  • Leads to home damage – Moisture seeps into wood floors, drywall, and furniture, causing warping, rot, and expensive repairs. Over time, high humidity can weaken your home’s structure and lead to mold growth inside walls.
  • Makes your air conditioner work harder – When humidity is high, your AC has to run longer to remove excess moisture, increasing wear and tear and inflating energy bills. This also shortens the lifespan of your system, leading to costly breakdowns.
  • Attracts pests – Silverfish, cockroaches, and even termites are drawn to damp environments. If you’ve noticed an uptick in unwanted guests, your home’s moisture levels may be to blame.

Experts recommend maintaining indoor humidity levels between 40-60%, but during summer, many St. Louis homes exceed this range without a dedicated solution.

Why an AprilAire Whole-Home Dehumidifier is the Best Solution for Your St. Louis Home

Some St. Louis homeowners try to tackle humidity with portable dehumidifiers, but these only work in small areas and require frequent emptying. They’re also ineffective at keeping moisture levels consistent throughout the home.

A whole-home dehumidifier from AprilAire offers a long-term solution by working seamlessly with your HVAC system to remove excess moisture from every room. Unlike a standard AC, which only dehumidifies as a side effect of cooling, a whole-home dehumidifier is designed specifically to maintain ideal humidity levels.

  • Reduces humidity throughout the entire home – Unlike portable models, an AprilAire whole-home dehumidifier integrates with your ductwork to regulate moisture levels in every room.
  • Works automatically with your HVAC system – Set it once, and it will continuously monitor and adjust humidity levels, requiring only annual professional maintenance.
  • Lowers energy costs – A drier home feels naturally cooler, reducing your reliance on air conditioning. By removing excess moisture, a whole-home dehumidifier allows your AC to work more efficiently, leading to lower utility bills.
  • Prevents mold, mildew, and odors – Once mold takes hold, it can be difficult and expensive to remove. By keeping humidity levels in check, an AprilAire system helps prevent mold before it starts.
  • Protects your home’s structure – Whole-home dehumidification preserves hardwood floors, furniture, and drywall, preventing costly repairs.

AprilAire dehumidifiers are built for durability, reliability, and quiet operation, ensuring your home stays dry and comfortable without added noise or disruption.

Why Spring is the Best Time to Install a Whole-Home Dehumidifier in St. Louis

As summer temperatures rise, so does humidity. Spring offers the perfect window for tackling humidity before it becomes a major issue. Installing an AprilAire whole-home dehumidifier now ensures your home stays cooler, drier, and more efficient all summer long.

  • Avoid the peak of summer humidity – High humidity levels can create issues quickly. Getting ahead of the problem prevents long-term damage and discomfort.
  • Take advantage of spring promotions – Many HVAC companies, including SmartHouse, offer special discounts or financing options before summer demand spikes.
  • Avoid peak-season installation delays – Scheduling in spring ensures faster service, as demand for HVAC upgrades and repairs increases during summer.
