Why Is My House Humid Even When The AC Is On?

Trust Mission AC To Repair Air Conditioner High Humidity

If you’re a homeowner in Virginia, you’re no stranger to humidity. When it’s muggy outside, entering the comfort of your home is a welcome escape, but only when your AC is working properly. However, if your house feels moist inside even with your system on, you’re probably eager for a cooling solution that will take your sweat away.

We’re humidity experts here at Mission Air. Since we’re based in Hanover, we know how difficult it can be to keep the moisture out of your home, especially when the outdoor humidity is high. If you’re wondering why your home feels so humid, we’re here to provide some answers.

Why Is My House So Humid All Of A Sudden?

Muggy conditions inside your home can be very frustrating. Not only is it uncomfortable, but it also can lead to mold growth and structural damage, both of which pose health and safety threats. In most cases, air conditioners effectively eliminate excess moisture. Unfortunately, issues can arise that prevent this from happening.

1. Old Unit

If your AC unit is over 10 years old, age might be to blame for indoor mugginess since they tend to struggle after 10–15 years of use. As the system ages, the evaporator coils that remove moisture from the air wear out and don’t work as efficiently.

Although you can clean and repair cooling coils, you may need to replace your entire system if it has a frequent need for repair.

2. Crowded Home

If you’ve ever been in a packed room, you understand the intensity of the heat people generate when they’re packed like sardines. If you have a lot of people staying at your home or you frequently host parties, the extra bodies occupying your home could be to blame.

To correct this problem, consider setting the thermostat down a couple degrees or moving a gathering outside if the weather allows.

3. Improper Unit Size

Your AC needs to be big enough to cool your entire home. If you have a unit that’s too small, it won’t be able to effectively remove excess moisture from the air. This problem will leave your home feeling stuffy. Similarly, a unit that’s too big may cool your home too quickly, not leaving enough time for the system to dehumidify the air.

4. Thermostat Settings

If your thermostat is set to “ON” instead of “AUTO,” your air conditioner unit will run constantly and fail to dehumidify the air. Make sure you place your system to the automatic setting if you want even temperature regulation and dehumidified air inside your home.

This solution is a simple fix that doesn’t require any repairs, although it won’t solve the problem if AC damage is to blame.

5. Weather

As simple as it sounds, a common cause of high indoor moisture is muggy weather outside. If the humidity levels outside are high, it’s hard to prevent some of the extra moisture from making its way indoors. A dehumidifier can combat this issue and keep your home comfortable on humid days.

What Is The Correct Humidity For A House?

Typically, your home should have a humidity level between 40–50 percent since this range protects the integrity of your house and promotes good health. Anything above this may lead to bacterial growth and other moisture problems, including the following:

  • Condensation on windows during winter
  • Dust accumulation
  • Peeling paint
  • Mold on walls, furniture and clothing
  • Mildew in bathroom

If you notice any of these issues in your home, you may need to contact an HVAC professional to assess your unit. This step toward drier living will protect you and your loved ones from discomfort and hazards, so it’s important to take action as soon as possible.
