Why Is My AC Blowing Humid Air?

Are you noticing that your air conditioner is blowing humid air instead of the cool and dry air you’d expect? If so, this article will explain why your AC may be exhibiting this unusual behavior and what you can do to fix the problem.

From checking your air filter to examining potential issues with your evaporator coils, there are a few possible culprits behind an AC unit blowing out humid air.

Read on to learn more about why this might be happening in your home and some simple solutions for solving the issue.

The AC Condenser Coils Need to Be Cleaned

The condenser coils located outside your home are responsible for removing heat and humidity from the air as it passes through them. Over time, these coils can become clogged with dirt, dust, debris, plant matter, and more.

This build-up of contaminants can prevent the coils from doing their job properly, resulting in humid air being blown into your home instead of cool and dry air.

To fix this issue, turn off your AC unit completely and spray down the condenser coils with a garden hose or pressure washer to remove any dirt or debris that has accumulated on them over time.

Be sure to clean out any visible grime or buildup around the area before you turn your AC back on.

Your Air Filter Is Clogged

Another potential cause of your AC unit blowing out humid air is that your air filter is blocked. The air filter helps to clean the air passing through it and into your home, trapping dirt, dust, and other particles.

If the air filter becomes clogged, air cannot pass freely through it, resulting in a buildup of moisture in your ducts and condenser coils.

To fix this issue, replace any dirty filters with new ones and check them frequently to ensure they are not becoming blocked or clogged.

The Evaporator Coils Are Frozen

If you’ve checked both the condenser coils and the air filter but still find yourself dealing with a humid AC unit, it could be due to frozen evaporator coils.

When the evaporator coils become too cold, they can freeze over and block air from passing through them properly.

To fix this issue, turn your AC off completely and leave it off for at least 24 hours to allow the evaporator coils to thaw out.

After 24 hours have passed, check the evaporator coils to make sure they are no longer frozen before you turn your AC back on.

You’re Not Using the Right AC Setting

Another possible reason your AC is blowing out humid air is that you’re not using the correct setting. Your AC unit should be set to “cool” for it to properly remove heat and humidity from the air passing through it.

If you find yourself dealing with a humid AC unit, check the settings on your thermostat to make sure they are set correctly.

Once you have confirmed that everything is set correctly, you should see an improvement in the quality of air being blown into your home.

Your AC is Old and Needs to be Replaced

If none of the above solutions are helping to fix your AC unit, it could be that your unit is old and needs to be replaced. Older air conditioning units tend to be less efficient at removing heat and humidity from the air, resulting in a buildup of moisture in your home.

In this case, you will likely need to invest in a new AC system for your home if you want to see any improvement in the quality of air being blown into your house.

The Outdoor Humidity is Very High

Finally, the outdoor humidity levels may be too high for your AC unit to effectively remove the moisture from the air.

If you live in a humid climate or if there has recently been a period of heavy rain or extreme weather conditions, this could be causing the issue.

To fix this problem, try using a dehumidifier in your home to reduce the overall level of humidity in your house and make it easier for your AC system to remove heat and moisture from the air passing through it.
