Summary
If you are dealing with AC humidity problems this August, you are not alone. Muggy summer weather in Bucks County makes it harder for your air conditioner to keep your home cool. High moisture levels force your system to work harder, which can lead to higher bills and uneven comfort.
How AC Humidity Problems Affect Cooling Performance
Humidity is the amount of water vapor is the air. In August, our region’s high dew points mean your AC must cool the air and remove moisture at the same time. This added strain can cause:
- Longer cooling cycles
- Less comfortable indoor air
- Higher utility bills
Scheduling air conditioner maintenance in Newtown helps your system stay efficient in humid weather.
Signs of AC Humidity Problems in Your Home
Longer Run Times Without Enough Cooling
If your AC runs for hours but the home still feels warm, humidity could be the cause.
Sticky or Clammy Indoor Air
Even at 72°F, your skin may feel damp if humidity control is poor.
Musty Odors and Condensation
Moisture buildup can cause musty smells and condensation on windows.
Common Causes of AC Humidity Problems
- Improperly Sized AC: Oversized systems cool air too quickly without removing enough moisture.
- Dirty Filters or Coils: Restrict airflow and reduce dehumidification.
- Low Refrigerant Levels: Weaken cooling capacity and humidity control.
- Leaky Ductwork: Allows humid air into your system.
Many of these issues can be prevented with annual service. Learn more in our blog on Understanding the Need for Annual Air Conditioner Maintenance.
