Why Is My Air Conditioner Not Dehumidifying As It Should?

Ever feel like a soggy piece of bread, damp and clammy, while sitting in your presumably air-conditioned room? Just like you, I have stared at my air conditioner, doubtful, wondering why it's not dehumidifying as it should. But then, I put on my repairman hat and rolled up my sleeves just like a true gentleman DIY’er. And here is what I found.

Understand the Dehumidifier within the Air Conditioner

Ah, science! It's like witchcraft but with proof. But no worries, we won't delve into the dry and tasteless ends of scientific principles. Instead, here's the fundamental concept: Air conditioners have a dehumidifying effect because the process of cooling air results in condensation. Whether you knew it or not, your air conditioner has been doubling as a dehumidifier this entire time! Now let's find out why it's slacking off in its duties.

A/C’s Three Villains: Underutilization, Overutilization, and Mismatched Size

To ensure your air conditioner is effectively dehumidifying, it needs to operate at its optimum levels which can be hindered by these three villains:

1. Underutilization

If you rarely use your A/C, there's a slim chance it can tackle the moisture problem effectively. The A/C needs a good run to reduce the humidity levels. Ensure you run it regularly, especially during the peak of moisture-laden days.

1. Overutilization

Sometimes, you accidentally turn your home into Antarctica, unbeknownst to you! When the A/C runs at lower temperatures for prolonged periods, it cools the air but doesn't effectively reduce humidity. Running A/C at moderate temperatures for longer durations is the secret to efficient dehumidification.

1. Mismatched Size

If your A/C is too big or too small for your room or house, its dehumidification capabilities suffer. Undersized A/C will struggle to cool and dehumidify, while oversized ones cool too quickly without adequately removing moisture. Thus, it's essential to install an A/C unit that suits your space size.

Check the Air Conditioner Settings

Is your A/C blowing out icy air that would put Jack Frost to shame, but you're still feeling clammy? You might want to check the settings on your air conditioner.

1. Fan Settings

Generally, AC units feature two fan settings: ON and AUTO. ON mode means the fan runs continuously, even if the A/C isn't actively cooling. This could lead to rehumidification because the fan pushes back condensed moisture into the room. AUTO mode is a better option as the fan runs only when the A/C is cooling, giving moisture no chance to re-enter.

1. Cooling Mode

Most modern units come with a dry mode, perfect for those grueling humid days. It operates at low speed, focusing on removing humidity over cooling. Keep this mode handy, but if your A/C lacks this feature, consider investing in a stand-alone dehumidifier for maximum comfort.

Check on the Air Conditioner Mechanics

Technical faults can affect the A/C's ability to dehumidify. Please monitor its refrigerant levels, evaporator coils, and ensure the filter is always clean. If all these don't improve the situation, it's time to call a professional.

Last Musings from an Aproned Fixer

So there you have it, folks. Now you are armed with all the necessary knowledge to combat this dehumidifying debacle. Remember, keep your cool (pun intended), and your air conditioner will, too. And whenever in doubt, don't hesitate to call your friendly neighborhood repairman. They say good humor is sunshine in a house, and I say an efficiently dehumidifying A/C comes as a close second. Stay cool and dry, my DIY friends!
