To reduce indoor humidity, run your air conditioner, add a whole-home dehumidifier, vent bathrooms and kitchens with exhaust fans, fix plumbing leaks, and keep gutters clear. Aim to hold relative humidity between 30% and 50%. In the Sacramento Valley, most excess moisture builds up from cooking, showering, and laundry rather than muggy outdoor air, so controlling those sources makes the biggest difference.
High humidity does more than feel sticky. Sustained levels above 60% can warp wood, feed mold, and worsen allergies and sleep. If your home still feels damp after trying these fixes, the team at Pearce Heating & Air Conditioning can measure your levels and recommend a solution, or handle AC Repair in Winters, CA and nearby communities when a struggling system is the real culprit.
Ideal Indoor Humidity Levels in Summer
HVAC experts recommend maintaining indoor relative humidity between 30% to 50%. Excess moisture (above 60%) can make you feel hot, damage your home, and pose health risks. High humidity can lead to structural damage, wood rot, and promote mold growth. It can also cause respiratory problems, allergy flare-ups, and disrupted sleep.
Maintaining a humidity level between 30-50% balances moisture levels, ensuring comfort and safety in your home.
How to Check Humidity Levels
Feeling hot and sweaty indoors is a clear sign of high humidity. To measure it accurately, use a hygrometer, which tracks relative humidity and moisture levels. At Pearce Heating & Air Conditioning, our experts can measure your home’s humidity levels and provide recommendations if it consistently exceeds 50%.
Ways to Lower Indoor Humidity
1. Use Your Air Conditioning System
Air conditioning naturally reduces humidity by introducing cooler air and removing warm, humid air. Ensure your system is well-maintained and filters are replaced regularly for optimal performance.
2. Get a Whole-Home Dehumidifier
Dehumidifiers, either standalone or integrated into your air conditioning system, remove moisture from the air. This not only improves comfort but can also reduce energy costs by making your AC system more efficient.
3. Utilize Exhaust and Ventilation Fans
Run your bathroom fan when showering and your stove fan when cooking. Keep them running a bit longer after these activities to further reduce humidity.
4. Open a Window
Opening a window can help reduce humidity, but avoid doing this while the air conditioning is running to prevent energy waste.
5. Lower Your Shower Water Temperature
Hot showers add humidity to the air. Lowering the temperature slightly can reduce steam and help control indoor humidity.
6. Fix Leaky Pipes
Leaky pipes and faucets add unnecessary moisture to the air. Repair leaks and insulate exposed pipes to prevent condensation.
7. Clean Your Gutters
Clogged gutters can cause water leaks and humidity buildup. Regularly clean your gutters and ensure downspouts direct water away from your home.
8. Dry Laundry Outside
Drying clothes indoors increases humidity. Use an outdoor drying rack or clothesline whenever possible. If drying indoors, use a dehumidifier to mitigate the added moisture.
9. Temporarily Relocate House Plants
Houseplants can increase indoor humidity. During summer, consider moving them to a well-ventilated room or outside temporarily.
10. Use Charcoal
Charcoal briquettes are highly absorbent and can help dehumidify rooms. Place them in a basket in various rooms and replace every 2-3 months.
