Have you ever felt sticky or muggy in your home even if the air conditioner is running? It’s a common occurrence for many homeowners, especially in the summertime. While your A/C cools your space, it also removes excess humidity for added comfort. If your home still feels humid, your system may not be performing as efficiently as it should. 

While high outdoor humidity is a contributing factor, there are several other reasons why this could be happening. In this blog, we’re covering a few different reasons why it may feel humid inside even if your air conditioner is running. 

Can an oversized A/C cause high humidity levels?

The size of your HVAC system does matter, especially when it comes to controlling humidity. Having an oversized air conditioner may cool your space too quickly without running long enough to remove moisture from the air effectively. Larger systems may be more likely to short-cycle because they reach your desired room temperature in a shorter amount of time. 

However, cooling your home quickly doesn’t give your air conditioning system enough time to remove excess moisture from the air. In that case, your home may feel cool while still feeling muggy and sticky from the leftover humidity. On the other hand, systems that are too small for your space may run for longer periods of time and have a harder time keeping up.  

It can be difficult for the average person to tell if their HVAC system is too big or too small for their home. However, some additional signs like higher energy bills, short-cycling, and uneven temperatures may indicate an issue. A professional, licensed HVAC technician from Black Diamond Plumbing & Mechanical can determine the cause of these problems and see if your system is the proper size for your home.

Does restricted airflow affect your air conditioner?

Restricted airflow may be another reason why your home still feels humid even if your air conditioner is running. Proper airflow is vital for maintaining comfortable humidity levels because your cooling system needs a continuous flow of air to circulate throughout your home while removing excess moisture.

Dirty air filters and leaking air ducts are a couple of the most common causes of airflow issues, which make controlling humidity more difficult. A clogged air filter can inhibit airflow, forcing your HVAC system to work harder while reducing its ability to remove excess moisture from the air. Leaking air ducts can allow conditioned air to escape before it reaches each room. This can make it more difficult to maintain comfortable indoor temperatures and control humidity levels.

In some cases, restricted airflow can even affect vital internal components like evaporator coils. Over time, restricted airflow can contribute to common problems such as dirty or frozen evaporator coils, making it more difficult for your system to remove heat and moisture.

A professional HVAC inspection from Black Diamond Plumbing & Mechanical can help pinpoint the source of your humidity issues before they disrupt your comfort.

Is my A/C in need of repairs?

Sometimes, high indoor humidity is a sign that your air conditioner needs attention. When certain components become worn or damaged, your HVAC system may not be able to remove moisture from the air as effectively, reducing your system’s overall efficiency. 

Even if your air conditioner is still effectively cooling your home, you may notice it struggles to remove moisture at the same rate. This can contribute to rooms feeling cool but sticky and muggy at the same time. You may notice it more when outdoor temperatures and humidity begin to rise. 

Most common air conditioning problems that may lead to high indoor humidity levels include:

• Dirty evaporator or condenser coils 
• Worn blower motor 
• Thermostat sensor issues
• Low refrigerant levels 

Since several different HVAC problems can cause similar issues, it can be difficult to narrow down what’s going on without a professional inspection. 

Contacting Black Diamond Plumbing & Mechanical for a professional inspection can help identify the underlying A/C problem and recommend a long-term solution to restore your home’s comfort.
