Why Is Water Dripping From My A/C Vents?

Why is water dripping from my A/C vents?

It might be a familiar sight to see your vehicle’s A/C dripping some water after it’s been parked for a few minutes. While this is a common occurrence that shouldn’t raise any red flags, the same can’t be said about your home’s air vents. If you notice water dripping from your A/C vents, the reasons range from fairly simple to complex. Below are four reasons why your vents may be dripping water:

1. Clogged Drain Line

A clogged drain line can result the build up of water inside the air vents. Head outside to the condenser unit and look for the drip pan. If it is very full or overflowing, it could suggest that your drain line is clogged. You should also look for rust on the furnace. Corrosion is another sign of a clogged drain line.

2. Damaged Drain Pan

Your A/C’s drain pan performs an important purpose by being a reservoir where the excess water from the unit collects. The drain pan then carries the water to the drain line. If this pan is damaged, the excess water won’t be able to drain properly.

3. Dirty Air Filter

A dirty air filter might not seem like it would cause your A/C vents to drip water, but it can be an indirect cause if your air conditioner freezes up. When you turn your A/C off, the frost will start to melt, causing water droplets to form.

4. Frozen Evaporator Coil

As mentioned above, if your A/C’s evaporator coil freezes, you might find that your vents drip water once the unit turns off. If your evaporator coil is frozen, it could be due to low levels of refrigerant. An bi-annual tune up of the system is recommended to ensure refrigerant levels are maintained, and if there is a leak it is identified quickly to reduce the potential of additional damage to the unit.
