High humidity is pretty unpleasant, right? It amplifies our discomfort during the scorching summer months by making us feel hotter and stickier, which is why most of us rely on our air conditioners for relief. However, most people are unaware that high humidity can impact their AC unit’s cooling capabilities as well!

Needless to say, the last thing you want is for your AC unit to unexpectedly stop working due to high humidity. Read on to learn more about how high humidity affects your AC unit and what measures you can take to avoid problems. 

What Does High Humidity Do to Your AC Unit?

Most traditional AC units don’t come with dehumidifiers found in modern HVAC systems. Even if you do have a newer AC unit, high humidity strains HVAC coils in such a way that they are unable to condense the atmosphere’s water vapour into liquid and drain it efficiently enough.

In other words, high humidity causes your AC unit to be ineffective when it comes to cooling your home or building. Here are some key indicators that your AC unit is working suboptimally due to high humidity. 

  1. A musty odor: High humidity levels lead to a damp and unpleasant odor within buildings.
  2. Cold and clammy air: If your skin feels unusually moist and clammy, it means your AC unit is not working properly.
  3. Foggy windows: Humidity is vaporized water in air. When it gets bottled up indoors, it fogs up surfaces like windows which is a clear sign of excessive humidity.

How do you identify problems with your AC unit before they manifest into something more serious? Well, installing a humidity sensor is the safest way to ensure you remain alert for anything out of the ordinary. 

Why Most AC Units Fail to Combat High Humidity

Most AC units do a poor job of controlling humidity because they consist of oversized systems, whereby powerful compressors turn on and off rapidly and don’t run long enough to remove moisture from the air. 

Apart from this, some AC units have poorly designed ventilation systems which result in negative air pressure—this causes humid air from outdoors to be drawn into buildings rather than humid air indoors to be filtered out.

Finally, your AC unit might just be old and lose efficiency due to wear and tear.
