High humidity during hot weathers can make the air feel warmer than the actual recorded temperature. This can then cause us to sweat more and feel hotter, as well as make everything hot and sticky. High humidity, furthermore, can have adverse effects on the body, which includes excessive sweating, dehydration, low energy, and heat exhaustion.
Discomfort and associated health risks only make it essential to do whatever you can to reduce or control humidity. A properly functioning air conditioning can offer some relief by lowering the temperature indoors. While the primary function of an AC is to blow fresh air and cool the room, it can also lower humidity and reduce warm air.
AC repair experts note that the evaporator coil (copper tubes) in your HVAC system plays a vital role in reducing humidity. This component condenses water vapor from the air and then sends it down the drain outside. The process can be compared to the condensation that you see on the outside of a glass or container that has a cold liquid or beverage.
When warm air is sucked from your house, it comes into contact with the evaporator coil, which then collects the moisture. But instead of letting the moisture drip down your AC, like what happens in a cold drinking glass, the liquid accumulates in the drain and is sent outside away from your home. This removes warm air and humidity, providing indoor relief during the summer.
Air conditioner sizes
Your AC can only be effective in removing humidity if it is correctly sized for the house or the amount of space it needs to cool. A window AC, for instance, might not be powerful enough for large areas or master bedrooms, as it is only designed for small spaces like a home office. If you think that your current AC is not doing a good job, it is probably not of the right size.
Keep in mind that your cooling system should not be too small or too big. An AC unit that is too small might not be able to lower humidity and keep your home cool, especially during extreme weather conditions. An oversized unit, on the other hand, is likely to short cycle or turn and off frequently, which will prevent the AC from sufficiently cooling the space.
Pick the right size
If you’re thinking of replacing an old unit, be wary of those contractors who tell you that a bigger unit is better. This is not entirely true, as more powerful equipment can only make uneven temperatures worse. A larger AC, furthermore, is more expensive and can lead to higher utility bills in the future. Other problems associated with an oversized AC include:
- Higher humidity in the summer
- Increased noise
- More duct leakage
- More repairs and breakdowns
- Increased molds and dust mite (triggering allergy symptoms)
If your unit is not removing humidity or is not functioning as it used to, it is best to have it checked professionally. Don’t try to troubleshoot the problem on your own, as you might end up adding more the damage to the unit.
