Why Is My Home So Humid Even When the AC Is Running?
Key Takeaways
Despite the fact that your AC seems to be running just fine, you may notice that your Central Florida home is still hot, damp, and uncomfortable. There are a number of potential problems with your unit that can cause humidity and HVAC inefficiency, including an oversized unit, coolant issues, clogged drain lines, and dirty air filters. As a first step, check to see if your unit is set to “on” or “auto,” since keeping the fan running all the time can prevent the unit from properly removing moisture.
Your AC is running. Your home’s temperature is dropping, and yet the moisture in the air is still high. As a result, you can end up sweating and feeling uncomfortable despite all your efforts to keep your home at a reasonable temperature. If you’re dealing with excess warm, damp air in your home, there are several things that might be to blame.
Your Unit Is the Wrong Size
An oversized AC unit can significantly increase humidity and HVAC inefficiency in your home. Instead of naturally cooling the air while removing warm air from it, your AC unit may cool the home fast, then shut off. This means it does not have enough time to take moisture out of the air during its usual cycle. If your home feels cool, but you still have too much moisture, you may need to talk to a professional to better manage your cooling needs.
You’re Low on Coolant
One of the most common issues with your air conditioner is low coolant. Inadequate refrigerant means that the coils in the unit will not get cool enough to condense water vapor. As a result, you may have trouble getting the unit to pull enough damp air to make your home comfy. You may also notice that it’s harder to keep your home at your preferred temperature. If you’re struggling with low coolant, make sure you bring in an AC repair service as soon as possible. If there’s a leak, you want to address it as soon as possible to keep it from getting worse!
Your Air Filter or Drain Lines Are Dirty
Over time, both air filters and drain lines can build up debris and dirt. Both need to be addressed regularly to keep your air conditioner running at peak efficiency. Blocked drain lines can leave moisture trapped in the system, which means it gets pushed back out into your home instead of being drained outside, while dirty, clogged air filters may restrict airflow to the coils and make it more difficult for them to effectively pull out that moisture. Regularly replacing your air filters and conducting maintenance on your drain lines can ensure that your unit provides optimal performance. It also helps reduce humidity and HVAC inefficiency.
Your Fan Is Set to On
If you’re struggling with warm, stuffy air, check your settings: are you set to AUTO or ON? If you, like many Central Florida residents, prefer to keep your fan running all the time, it could actually be increasing moisture levels in your home. When the fan runs constantly, any moisture collected on the coils is evaporated quickly and blown straight back into the home. Try keeping your air conditioner set to AUTO to see if the issue improves.
