During the summer, your air conditioning unit will work overtime to keep your home as cool as possible. You may notice water droplets on your unit which are beads of condensation. While this doesn’t mean your AC unit is in trouble, it may be something to investigate further.
Why Does Condensation on Ducts Occur?
As the humidity levels rise outside during the summer, condensation will likely form on your air conditioner unit. The cooler the air inside the ducts is, the more likely condensation will build up. If you own an older home or your ductwork is not properly maintained, you are more likely to see condensation on your unit. However, other factors may contribute to the presence of condensation, such as:
- Poor insulation
- Excessive moisture in the air
- Dirty air filters
- Blocked ducts
The Dangers of Duct Condensation
- Excessive humidity: High humidity levels inside your home can be caused by plumbing emergencies or even air drying your clothes. These high humidity levels, paired with extensive use of your air conditioner, can lead to condensation on your unit. This buildup of water needs to go somewhere, so it may rust metal pipes and leak into wooden infrastructure or drywall.
- Mold buildup: The longer water and condensation sit in your home and leak into your infrastructure, mold and mildew will likely build up, causing hazards within your home. Mold and mildew growth can lead to many health risks, especially for those with allergies or compromised immune systems.
- Damaged insulation: Condensation buildup is also likely to drip into the insulation in your home. As your insulation fills with water, it becomes much more defective and will rack up your energy bills.
- Condensation Solutions and Prevention
- Reduce indoor humidity: If excessive humidity is the problem, consult a professional to look at what could be causing excessive indoor moisture. You can also invest in a dehumidifier and other moisture-reducing products. If you use a dehumidifier, it is vital to check the reservoir regularly to avoid water overflow.
- Regular duct maintenance: Keeping your air ducts clear and free from dirt, dust, and debris is a great way to ensure condensation and moisture don’t build up and encourage efficient airflow. Checking your ductwork yourself isn’t recommended, so consider contacting a HVAC professional for this inspection.
- Upgrade your duct insulation: If poorly insulated ducts are the problem, you must get your ducts upgraded or replaced. Sealing and insulating your air ducts will prevent them from getting overly cool, preventing condensation from forming.
