How to Unclog Your AC Drain Line

Many people don’t know this, but your AC does more than just cool your home. It also removes humidity in your home so that the inside climate is ideal for you to live in. But sometimes, the part of your AC responsible for removing that access humidity gets clogged. It’s important to keep this part unclogged for reasons beyond dehumidifying your home. A clogged AC condensate drain line may cause condensation to leak and cause water damage. So, what can you do to prevent this?

What causes AC drain lines to clog?

There are multiple reasons why an AC drain line can clog, but living in Florida, it’s mainly due to humidity. The warm air that blows over the cold evaporator coil on the HVAC unit causes humidity. When condensation travels through the pipe, it creates a perfect environment for algae to accumulate. Central Floridians often keep their AC running 24/7, so it’s more likely to clog. Algae are known to cause issues for your AC, so it’s important to take preventative measures to keep your AC running efficiently.

Another reason AC drain lines clog in Florida is due to rain and storms. Debris from storms can cause leaves and sticks to block your unit’s drain line. With a backup of debris, the AC unit can shut down and negatively affect the system.

Symptoms of a Clogged AC Drain Line

Thankfully, there are signs that your AC drain line may be clogged. The most common symptoms include:

  • AC system shutting down or completely turning off
  • Water damage in areas near the indoor unit
  • Puddles of water near the indoor unit
  • Moldy smells near your indoor unit or circulating air from the vents
  • AC system not cooling your home

If your AC system isn’t working as it should, it’s usually a sign that something is wrong. But, you don’t have to take care of the problem yourself. Our HVAC professionals are here to help. Call us today to schedule your appointment.
