Just like any other water leaks, moisture collecting around your air conditioning vents is never a good thing. The property damage, mold growth, and expensive repairs that can follow the problem can be traumatic. So why is condensation dripping from your A/C vents? Let’s explore the reasons behind the formation of vent moisture along with what you can do to remedy the matter.
Clogged Drain Line
A clogged condensate drain line is one of the most common causes of water collecting around A/C vents. Over time, dirt and debris can clog up your air conditioner’s drain line. Inspect your outdoor A/C unit. Is the drip pan full or overflowing? If yes, you probably have a clogged drain line that will need thorough cleaning to unclog it.
Air Leaking From Around the Vents
Water dripping from the area around your air vent can be the result of an air leak. Put your hand under the vent and feel if there’s any air escaping from its sides. If you feel air coming from the sides of the grates, you’ll need to apply caulk to the area to create a seal.
Poor Insulation
Excess condensation can occur if your ducts aren’t adequately insulated. Remove the grates from your A/C vents and inspect the ductwork. If it lacks insulation, you’ll need to have it properly insulated.
Dirty Air Filter
A dirty filter can make your air conditioner freeze up. As the frost melts, the water droplets can drip down through the vents. Change your air filter regularly to prevent this from happening.
Refrigerant Leak
A refrigerant leak can also cause condensation to drip from your A/C vents. If you spot vent moisture as well as experience low airflow or air that’s not cool enough, your A/C system is highly likely to be low on refrigerant. This problem is best solved by an HVAC specialist.
Vent moisture usually indicates problems with your air conditioner. Luckily, these problems can be easily fixed and prevented with professional A/C maintenance. For dependable routine preventive maintenance in the Dayton area, contact the A/C experts at Ace Hardware Home Services.
