Managing Humidity at Home: HVAC Tips for Pennsylvania’s Swing Seasons

In Pennsylvania and West Virginia, spring and fall are known for their unpredictable weather—warm one day, chilly the next, and often accompanied by fluctuating humidity levels. These “swing seasons” can make it difficult to maintain comfort indoors without the right HVAC setup.

At Van Bremen’s Heat & Air, we know that managing indoor humidity is just as important as temperature control. Whether it’s excess moisture in the air or the uncomfortable dryness that comes with cooler days, here’s how to keep your home feeling just right year-round.

Why Humidity Matters

Humidity plays a big role in how comfortable (or miserable) your home feels. The ideal indoor humidity range is generally between 30% and 50%. When humidity falls outside this range, you may notice:

• Too Much Humidity:

  • Musty smells

  • Mold or mildew growth

  • Sticky, uncomfortable air

  • Foggy windows

• Too Little Humidity:

  • Dry, itchy skin

  • Increased static electricity

  • Dry sinuses and respiratory issues

  • Cracked wood flooring or furniture

The Challenge of Swing Seasons

Spring and fall are tough on HVAC systems because:

• Outdoor humidity is inconsistent

• Heating and cooling are both needed at different times—sometimes in the same week

• Rain, wind, and sudden temperature drops create new challenges almost daily

Your HVAC system needs to be flexible and well-maintained to adjust to these shifts effectively.

HVAC Tips for Managing Humidity in Spring & Fall

1. Use a Programmable or Smart Thermostat

Smart thermostats can automatically adjust fan speeds and indoor temperature to help regulate both temperature and humidity. Some models even offer humidity sensors and controls built in.

2. Keep Up With Filter Changes

A clogged air filter restricts airflow and can throw off your system’s ability to manage moisture. During swing seasons, check filters monthly and replace them as needed.

3. Consider a Whole-Home Dehumidifier or Humidifier

• Dehumidifiers help during the muggy spring days when it feels like summer arrived early.

• Humidifiers are helpful in fall when heating systems start running and the air dries out.

Van Bremen’s installs whole-home humidity control systems that integrate directly with your HVAC system for consistent results throughout your home.

4. Ensure Proper Ventilation

Use exhaust fans in bathrooms and kitchens to vent out steam and moisture. For homes with limited airflow, consider having our team inspect your ventilation system and attic insulation.

5. Seal Air Leaks and Ductwork

Leaky ductwork or poorly sealed windows and doors can pull in outdoor air—bringing humidity along with it. We can inspect your ducts and recommend air sealing or insulation upgrades where needed.

6. Don’t Oversize Your HVAC System

An oversized air conditioner or furnace can short-cycle, meaning it turns on and off too quickly to properly remove moisture or distribute heat. If your system struggles to maintain comfort, it may be time for a load evaluation.

Bonus Tip: Schedule a Seasonal HVAC Tune-Up

Regular maintenance ensures your system is operating at peak efficiency—especially during the seasons it’s working the hardest. Van Bremen’s spring and fall tune-ups include a thorough inspection of humidity controls, thermostat calibration, airflow, and filter condition.
