High Humidity

High Humidity

When the summer days are scorching hot and the humid air feels heavy, we rely on our air conditioners to cool us down. But if you turn on your AC unit and the air still feels muggy, you may have an issue. When the indoor air quality feels no different from outdoor temperatures, it’s time to call an expert HVAC technician. We’ve listed the reasons why you could be experiencing high humidity inside.

Frozen Evaporator Coils

If your air conditioner is not hitting the set temperature, check the evaporator coils. If ice builds up, it prevents the refrigerant from working as it should. If your air conditioner isn’t removing moisture from the air, it could be due to the evaporator coils.

Evaporator coils can also become frozen when you have a dirty air filter. A dirty filter might affect the HVAC performance. In addition, clogged condenser units, low refrigerant levels, and other issues could cause freezing. You could also be overusing it, so don’t keep the AC running when you don’t need it.

By turning off your air conditioner for a day, it has time to thaw. If you put the filters back and the humidity levels haven’t changed, it’s time to call a professional in Houston AC repair may be the answer.

Thermostat Settings

The AC system has different thermostat settings for both heating and cooling. The high indoor humidity could be a cause of not setting the AC system in the correct mode. You need to check that it says cold. If not, it can affect the temperature and humidity inside the home. You should also set the temperature to 68.5 to 80.5 degrees Fahrenheit.  

In the HVAC system, the fan setting typically refers to the speed or intensity of the blower fan that circulates cool air throughout the space. The fan setting is adjustable to control the amount of air circulated and the rate at which the space is cooled. 

If your unit is on the fan setting and not on cold, then the fan is not on and not the air conditioning, which can cause humidity in your home.

One of the main reasons you experience high humidity levels is that just the fan is running. Making sure you’re in the right mode can help lower humidity levels.

Outdoor Humidity

When there are high levels of humidity outside, your AC unit is working full-time. It may be worth buying a dehumidifier to fight off the muggy air. A high humidity level can often contribute to the house not cooling in time. AC repairs might not even be needed, and opening the windows isn’t always the answer. With the humidity air conditioning repair in Houston, TX might be needed. 

When there are high humidity levels, your HVAC system simply can’t remove the moisture in the house. Once the temperature outside improves, the house will feel much better. A dehumidifier will take the weight off the air conditioner and will assist in removing the moisture. In addition, the indoor humidity levels will be reduced.  


You may have noticed that your windows are steamy due to indoor relative humidity levels and you are unaware of how to improve the situation. One good way is to perform regular maintenance on your air conditioning. Start by checking the condenser coils. If they are not clean, your HVAC won’t be able to remove moisture and the cooling won’t be as efficient. You will end up with humid air indoors. You can call a technician to have a look at the unit to find out why it’s not cooling as it should. This is because it may be time for an AC repair

Air conditioner condenser coils play a crucial role in removing heat and moisture from indoor air by using refrigerants and releasing heat outside. However, a buildup of dirt, grime, or other debris on these coils can impede their ability to transfer heat effectively. As a result, the refrigerant may be unable to cool the air and reduce the humidity levels in your home. 

When the condenser coils are dirty, they can make your house feel hot and humid. They can also cause your air conditioning unit to work harder, resulting in increased energy consumption and higher energy bills.

Even if you’re not getting the desired cooling effect, your AC unit will work harder to compensate for the reduced airflow. It’s essential to maintain the cleanliness of your air conditioning components. If you’re unable to address the problem on your own, it’s best to seek professional assistance from an HVAC expert. They can identify the underlying cause and recommend the most appropriate solution, which could include a HVAC repair. It’s important to do so before it’s too late and you might need an AC replacement

AC Size

High levels of humidity in your house can occur when you have the wrong AC size. This refers to the cooling capacity of the unit, not its physical size. An oversized system may seem like a better option to cool your home, but it may not effectively control both temperature and humidity. An oversized AC system tends to turn on and off frequently, leading to inadequate cooling and high humidity levels. Choosing the right size unit for your AC system can reduce moisture levels.
