How to Fix 3 Common Air Conditioner Moisture Problems



1. Too Much Condensation in Pan

Air conditioner moisture problems can develop for a variety of reasons. Understanding the cause will enable you to troubleshoot the areas that need attention.

Summer months are filled with high humidity levels that are difficult to cope with. The average comfort level of the body ranges between 30% and 50% relative humidity. During hot spells, the outdoor humidity levels can reach 100%.

Before taking the following steps, use safety precautions by shutting off the air conditioner unit and disabling the breaker.

It is normal for condensation to form around the coils and to drip into the drip pan. You may notice more water forming on extremely humid days. However, if the collected water is going beyond the pan, these steps need to be taken.

Check the pan for any cracks or holes that are present. After extensive use, there could be damage of rust forming or hairline cracks from weather and wear. This is a relatively simple fix.

Remove the pan and patch any holes or weak areas with epoxy glue. However, to be safe of future problems, the pan should be replaced.

A blocked condensate drainage line may be causing a back-up of water that is intended for the drainage pan. Dirt, insects or any outdoor debris can find their way into a drainage line. Disconnect the line and remove the blockage.

This can be done with a hand pump or a wet dry vac. A drainage line can also rust through and leak water. This can slow down the production of the unit and cause standing water around the unit. If there is substantial damage, replace the line. This should eliminate future air conditioner moisture problems.

If you notice water standing in your drip pan, check the evaporator coil. If it has a build-up of ice, air conditioner moisture problems could be the cause.

Although the manual may state to check every 2 to 3 months, humid weather delivers more dirt to the unit in a short amount of time. When a filter becomes clogged, coils can become too cold and freeze up. As they melt, an excess of water is made. Make a note to change the filter every month during the hot summer months.

2. Frozen Evaporator Coil

Poor insulation can create openings that break the seal intended for the unit. As the air seeps out, air conditioner moisture problems occur. Check the insulation for tears that may have happened over the winter months. If there is a leak, the insulation will feel damp in spots.

Replace parts if needed. If your unit is located in an attic or basement, surrounding wood can become in danger of further damage so don?t delay.

3. Interior Moisture Collection

Broken seals that keep the air flow of the air conditioning unit contained can just wear out with continuous use. This is not a job that can be easily pinpointed or repaired.
