Is your Langley home feeling clammy even with the AC running? Living near Grand Lake is a gift, but summer humidity can make rooms feel sticky and hard to cool. You want simple ways to stay comfortable and protect your place from moisture issues. This guide gives you practical steps, smart upgrades, and local resources tailored to Langley and Mayes County. Let’s dive in.
Why Grand Lake summers feel so humid
Langley sits right on Grand Lake, so summer air carries extra moisture. The Oklahoma Mesonet Mayes County page shows that summer months often bring daily average relative humidity in the mid 60 to mid 70 percent range with average dew points in the upper 60s Fahrenheit. The National Weather Service Pryor climate page notes July and August are typically the hottest months. That heat plus high dew points increases cooling and dehumidification demand inside your home.
What high humidity does to your home
Comfort and health
When indoor humidity stays high, sweat does not evaporate well, so you feel warmer than the thermostat reading. Health agencies recommend controlling both temperature and humidity for comfort. The EPA’s mold and moisture guide advises keeping indoor relative humidity below 60 percent and ideally 30 to 50 percent. Damp conditions can also aggravate allergies and asthma according to CDC guidance on mold and health.
Materials and systems
Moisture can cause condensation on cool surfaces, peel paint, warp wood, and damage stored items. Mold can begin to grow on wet surfaces within 24 to 48 hours if areas are not dried promptly. AC units remove some moisture while cooling, but persistent high dew points make them work harder and can raise energy use. Routine maintenance keeps them removing moisture effectively, as outlined in the EPA’s HVAC and moisture training.
Quick wins you can do this week
- Run exhaust fans in bathrooms during and 20 minutes after showers. Use your kitchen range hood while cooking and boiling. Vent to the outdoors, not the attic. Guidance from the EPA’s mold and moisture guide supports this.
- Vent the clothes dryer outdoors. Avoid air drying large laundry loads inside during humid months.
- Dry spills and leaks fast. Aim to dry within 24 to 48 hours to discourage mold.
- Use a hygrometer. Place inexpensive digital hygrometers in the main living area and in a crawlspace or basement to track relative humidity.
- Be strategic with windows. If outdoor air is more humid than indoors, opening windows will raise indoor moisture. Monitor readings and adjust accordingly.
Room by room playbook
Basement and crawlspace
- Encapsulate crawlspaces where appropriate. A sealed vapor barrier, insulated walls, and a dedicated crawlspace dehumidifier can prevent soil moisture from migrating into the home. Many professionals in humid regions recommend this approach for summertime control. Learn more about encapsulation benefits in humid areas from this regional overview of crawlspace dehumidifiers in Oklahoma and Texas (industry explainer).
- Slope, gutters, and drainage. Keep soil graded away from the foundation and maintain gutters to move water off the lot. The EPA’s moisture guide lists drainage as a first line of defense.
Bathrooms, kitchen, and laundry
- Use ventilation every time. Run bath fans during and after showers. Use your range hood when simmering and keep pot lids on to reduce steam.
- Prevent moisture buildup. Repair drips, and avoid line drying bulky loads indoors during humid stretches.
Living areas and bedrooms
- Add a portable dehumidifier in problem rooms. Set a target around 45 percent RH in summer and use a hose to drain continuously where possible. See sizing tips from ENERGY STAR’s dehumidifier guidance.
- Manage soft surfaces. Avoid storing cardboard and fabrics in damp areas. Use breathable storage bins where needed.
When to invest in upgrades
Whole house dehumidifier
If the whole home stays above 50 percent RH even when the AC is working, a ducted whole house dehumidifier can stabilize humidity across rooms. These systems tie into your ducts and are sized by a licensed HVAC pro. Review what to expect from ENERGY STAR’s overview of dehumidifiers.
HVAC tune ups and right sizing
Have a professional service your system each year. Clean or replace filters, clear condensate drains, and confirm refrigerant charge and airflow to keep moisture removal on track. Oversized ACs can short cycle and remove less moisture. The EPA’s HVAC moisture course explains why maintenance and correct sizing matter in humid climates.
Outside fixes that help inside
- Plant smart shade. Deciduous trees on the south and west can reduce solar heat gain, which lowers cooling load and helps your AC manage humidity. See tips in DOE’s landscaping for shade guidance.
- Maintain airflow and clearances. Trim dense vegetation against the house so walls can dry after rain. Keep mulch and soil away from siding.
Spotting mold and what to do
If you see small patches under 10 square feet, you can often clean with standard methods and dry the area thoroughly. For widespread growth, hidden sources, or recurring problems, contact a licensed remediation contractor. Always fix the moisture source first. The EPA’s remediation guide outlines when to call a pro and how cleanup should proceed.
Local help and rebates in Mayes County
- Track local conditions. Use the Oklahoma Mesonet Mayes County page to watch humidity and dew points so you can time ventilation and dehumidifier use.
- Get practical home advice. The Mayes County OSU Extension Office offers research-based resources on moisture control, landscaping, and referrals to local services.
- Check rebates and audits. Oklahoma utilities and co-ops often provide audits and rebates for efficient HVAC and sometimes dehumidifiers. Start with the state’s energy efficiency resource hub to find current programs and links to local providers.

FAQs
What indoor humidity is best for Langley summers?
- Aim below 60 percent and ideally 30 to 50 percent, with about 45 percent a practical target for comfort and mold prevention per the EPA’s moisture guide.
Can my AC handle Grand Lake humidity by itself?
- Sometimes, but persistent high dew points can leave rooms feeling clammy. If humidity stays above 50 percent with the AC running, consider a whole house dehumidifier or HVAC adjustments after a professional check. See ENERGY STAR’s dehumidifier overview.
Should I buy a portable or whole house dehumidifier first?
- Start with problem rooms using a portable unit and address habits and ventilation. If the whole home stays humid, a ducted whole house dehumidifier is the more comprehensive fix per ENERGY STAR guidance.
How do I know when to open windows in humid weather?
- Compare indoor and outdoor humidity with a hygrometer and local data. If outdoor air is more humid, keep windows closed and use mechanical ventilation and dehumidification. Local trends are visible on the Mesonet Mayes County page.
When should I call a professional for mold?
- If growth is larger than 10 square feet, keeps returning, or involves hidden areas or HVAC, contact a licensed remediator and fix the moisture source. The EPA’s remediation guide explains thresholds and steps.
