Summers in Wentzville and throughout St. Charles County are marked by high humidity, forcing your AC to operate more diligently. Homeowners frequently observe that the air feels damp or sticky, even when temperatures are cooler. This occurs because air conditioning systems prioritize cooling the temperature before addressing humidity levels. 5 Quick Fixes Before You Call a Pro: Verify that the thermostat fan mode is set to AUTO rather than ON. Replace air filters monthly during the peak season. Ensure that supply and return vents are unobstructed. Gently clean outdoor condenser coils with a hose spray. Consider installing a whole-home dehumidifier (we offer models that seamlessly integrate with your system). When to Call Johnson Heating & Cooling? AC runs constantly but doesn’t remove moisture.
