Common Causes of Excess Condensation on HVAC Ducts

The whirl of a blower, occasional dripping water, and the compressor’s hum are some of the typical sounds associated with the running of an HVAC unit. The occasional water dripping sound denotes the development of condensation along your system’s evaporator coils. When water flows through your evaporator coils, heat is absorbed, and moisture is formed, which will drip into a condensate pan. There is a drain pump that moves this wastewater toward the plumbing.

Excess condensate accumulation in your HVAC unit necessitates the services of a plumber in Salt Lake City. This is evidenced by unexplainable high energy bills, poor indoor comfort, low air quality, and leaks from your air conditioning vents. This might not bother you as much, but the excess condensation causes water damage on various elements in your property, contributes to mold and mildew infestation, and causes the rust of metallic parts in your unit. The following are some of the causes of excess condensation in your HVAC system:

Plugged Condensation Lines

If something plugs your drain line, it will contribute to the condensate accumulation in your system. Most HVAC units have secondary condensation pans to avert leaks in case debris and other elements block the primary line. If you have a float switch in the secondary condensation pan, it will cut off your HVAC unit’s operation and point you to an issue in your primary drain lines. This way, you can have the cause of the blockage addressed before you have to deal with costly water damage.

Excess Humidity

The air in your surroundings has some water present, although you cannot see it. However, there are times when the water in your surroundings becomes too much and the air cannot hold onto more water. This excess humidity in your surroundings might be the primary contributor to condensate on your HVAC’s vents. The humidity will turn into condensate when it comes into contact with the cold air from your unit. This develops into significant leaks over time. The solution, in this case, is to install a dehumidifier in your property to get rid of the humidity.

Inadequate Insulation

The insulation surrounding your HVAC unit is meant to prevent the formation of condensate in your system by forming a vapor barrier. In most cases, DIY insulation will contribute to the creation of condensate on your vents when the warm air mixes with the output from cold vents. In some cases, the insulation might have been torn by pests, causing it not to function optimally.

Incorrect Unit Slopes

When your evaporator drain is not adequately sloped toward the drain pan to drain the water, it contributes to condensation in your system. This will also be the eventuality if your drain pipe is not sloped correctly. Both of these issues can only be prevented by professional HVAC installation.

Condensation from any of the causes mentioned above might take some time before it is evident, more so if it is minimal. The ideal solution is to stick to regular HVAC professional maintenance. This way, you will alleviate considerable damage to your unit and property, secondary to excess condensate accumulation.
