My AC is Running But My Home Feels Humid — What’s Wrong?

Humid house even with the ac on

When the AC system in your home doesn't work correctly, you may end up experiencing high levels of humidity and other issues such as stuffy air or hot spots throughout your house. If your AC is on and it feels like the humidity level in your home hasn't changed, you may wonder what's wrong.

Why is Your House Humid with the AC On

If your house is humid with the ac on, there is likely an issue with your air conditioner that is preventing it from dehumidifying. Frost build-up on your evaporator coils is the most common reason for humidity, but can also be caused by leaking ductwork or excess amounts of dirt and debris.

Let's now break down the possible causes of humidity in your home and tips on how to remedy it.

Frozen Evaporator Coils

When your evaporator coils are covered in frost, they can't perform their function. As a result, your air conditioner will run less efficiently, and your home will feel more humid.

Leaking Ductwork

Another possible cause of indoor humidity is leaking ductwork. If there are cracks or holes in your ductwork, air will escape, and moisture will enter. This can lead to an increase in indoor humidity levels.

If you think your ductwork may be leaking, have it inspected by a professional. They'll be able to determine if there are any leaks and repair them as needed.

Dirt, Dust, and Debris

If you notice that your AC is running, but your home feels humid, be sure to check your system for any dirt or debris buildup. Outdoor condenser coils are especially susceptible to environmental conditions, so keeping them clean and functioning properly is essential. If they become impaired, it can disrupt the refrigerant cycle and lead to higher temperatures and a lack of dehumidification.

A Dehumidifier Can Help

If your home is excessively humid and you can't seem to get it under control, a dehumidifier may be the answer. Dehumidifiers work by removing moisture from the air, which can help to reduce humidity levels in your home.

Dehumidifiers can be used with your air conditioner to improve its efficiency and help keep your home comfortable. If you're not sure which dehumidifier is right for your home, our team can help you select the perfect model.

Whole-house dehumidifiers work similarly to air conditioners by removing moisture from the air. Water vapor is drawn from the air using a refrigerant-cooled coil, where it accumulates and is subsequently removed through a drain.
