Everything You Need To Know About Aircon Condensation

The summer months are when your air conditioner has to work the hardest to keep your house cool. Because your air conditioner is turned on continuously, you might wonder when you suddenly see water droplets collecting on your visible air ducts, is it normal?

Condensation, commonly referred to as ductwork sweating is something that needs your attention even though it does not necessarily imply that your air conditioner system is having problems. Condensation will gradually start to accumulate on the surface of your air conditioning ducts as external humidity levels climb.

Though this is a fairly common issue that might affect air conditioners, constant condensation could cause your air conditioner system to have several problems.

What causes condensation?

The temperature difference between the outside and the air conditioner vent, inadequately sealed air conditioner ducts, and a lack of insulation around these ducts, are the main contributors to condensation in your system. But other things can also contribute to making condensation in air conditioners worse:

• Too much air moisture
• Dirty air filters
• Clogged ducts

Sometimes duct condensation might be an indication that a duct is leaking air, which lowers the effectiveness of your air conditioning equipment. Ductwork sweating is more likely to develop as the temperature and humidity levels rise if you live in an older home or if your ductwork is not properly maintained.

When should I worry about condensation on air conditioner ducts?

Although occasional condensation on air conditioner ducts is not harmful, you must still keep an eye on the issue. When ductwork sweats frequently, water damage may eventually result.

Excessive condensation can also foster the growth of mold or mildew. If mold and mildew start to grow and then move to other areas of your home, people who have asthma and allergies may experience worse symptoms.

What can I do about ductwork sweating?

Instead of using metal consider flexible, fiberglass, and insulated materials to prevent duct condensation and leaking. If you do have metal ducts, make sure the fiberglass insulation is applied properly. While a good fit is essential, overly tight insulation will have a lower impact on ductwork perspiration. Here are some things to consider when troubleshooting condensation in the ductwork.

• Make the area surrounding your air ducts less damp, by keeping ducts apart so that air can pass through them. Cover the soil in the crawl space beneath your home if there are ducts there to cut down on dampness. Also, make sure the area is well insulated and any cracks or holes are sealed. A dehumidifier can also help keep the air surrounding your ductwork dry if you live in an area that is frequently humid.
• Have any ducts that are obstructing airflow cleaned frequently. The chance of ductwork sweating rises when the air in your air conditioner cannot move freely since it will get colder inside the ducts.
• Change your air filters frequently and keep them clean. It is advised to change filters every one to three months. You might need to change the filter more frequently if you have pets or if someone in your household suffers from a dust allergy.
• Fixing duct leaks. Condensation will form more frequently the more cold air that escapes. A pressure gauge or simply placing your hand on the duct to feel for air leaving can be done to find a leaky duct.
• Make sure to do regular aircon servicing to make sure that any minor damage can be fixed immediately, thus preventing it from turning into a major problem.

How can I tell when the air conditioner unit needs to be repaired?

It could be time to have an expert identify the root cause of your ductwork sweating and address the issue if you see any of the following symptoms.

• A decrease in airflow may indicate that your air conditioner’s compressor is no longer operating properly. If changing the indoor air filter doesn’t help, the compressor might require repair.
• A noisy air conditioner could be a sign there is a problem with the fan inside the unit.
• A rapid increase in condensation on the aircon unit’s exterior may indicate a problem with the pressure or internal temperature.
• Uneven temperatures throughout your house.
• Foul odors emanating from your air vents may be an indication that the air conditioner unit needs professional cleaning and repair.
• Higher utility bills than in prior years, especially during the summer, may be a clue that your air conditioner unit is having trouble keeping your home cool.
