What causes high humidity in a house in summer?
When an AC unit’s capacity is much too large for a home, it cools too quickly and in short, ineffective cycles. This causes it to turn on and off frequently, allowing humidity to take hold. You see, the evaporator coil inside the AC helps act as a dehumidifier, by pulling moisture from the air.
What is a good indoor humidity level in summer?
During summer months, the average humidity should weigh in between 30-45 percent (below the 50% mark). Winter may require lower than 40% relative humidity to avoid condensation on your windows.
How can I lower the humidity in my house?
How Can I Reduce My Humidity Levels?
- Use Your Air Conditioner.
- Actively Use Your Exhaust/Ventilation Fans.
- Take Cooler Showers.
- Fix Any Leaking Pipes.

How do I lower the humidity in my house with AC?
4 Ways to Make Your AC Remove More Humidity
- Keep your coil clean. When your evaporator coil ( indoor ) is covered in dust and dirt, it can’t remove all of the heat and humidity that it’s designed to remove.
- Adjust your fan speed.
- Install a thermal expansion valve, or TXV.
- Check your refrigerant charge.
Is 70 humidity in a house too high?
Research from the Building Science Corporation found that humidity of 70 % or higher adjacent to a surface can cause serious damage to the property. The Health and Safety Executive recommends that relative humidity indoors should be maintained at 40- 70 %, while other experts recommend that the range should be 30-60%.
Do fans lower humidity?
When it is warm, and you are looking for an effective yet inexpensive way to reduce humidity, ceiling fans are a straightforward solution. When you turn on a ceiling fan, the breeze evaporates excess moisture, which makes you feel cooler.
What humidity grows mold?
Many species of mold can grow and thrive on humidity alone if the humidity level stays high for a sufficient period of time. Humidity levels typically need to be at 55% or higher before mold begins to grow.
What is the ideal home humidity?
The ideal relative humidity for health and comfort is somewhere between 30-50% humidity, according to the Mayo Clinic. This means that the air holds between 30-50% of the maximum amount of moisture it can contain.
Why is my house humidity so high?
Everyday actions like cooking, washing the dishes, running the washing machine, taking a shower, sweating and even breathing can cause moisture to build in your home—especially if you’ve got a big family. Leaks. Moisture could also be entering your house through leaks and cracks in or around your home.
Does cold air reduce humidity?
Cold air can’t retain as much moisture, so high humidity is less common in chilly weather. Inside your house, lowering the temperature is an effective way to minimize humidity to a certain extent, because the air simply can’t hold on to the same level of moisture when it’s cooler.
How can I get humidity out of my home without a dehumidifier?
How to reduce indoor humidity without a dehumidifier
- Ventilate your room.
- Air conditioning.
- Replace Furnace / AC filters.
- Take shorter or colder showers.

Should AC fan be on auto or on?
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
What should I set my AC humidity too?
It adds moisture to air before it is forced through the ducts in your home. An indoor humidity level of 30 – 40% is recommended in the winter months; depending on your personal preferences, this may be even higher. The end result is a warmer, more comfortable home and a likely reduction in your energy bills.
Why my air conditioner is not lowering humidity in my home?
Normally your air conditioner lowers humidity by circulating your humid air over a cold evaporator coil (copper tubes). But if your air conditioner isn’t dehumidifying the air properly, it’s probably because of one of these issues: Thermostat is set to “ON” instead of “AUTO” Dirty evaporator coil.
