What If Your Air Conditioner’s Drain Line Is Clogged?

What If Your Air Conditioner’s Drain Line Is Clogged?

Have you ever had your air conditioner’s drain line clog? It can be a very messy and sometimes dangerous situation. We’ve seen clogged drain lines:

  • Cause hundreds, even thousands of dollars in water damage to ceilings, walls, floors, and carpets.
  • Cause damage to electrical components inside the HVAC equipment.
  • Create humidity build up in areas the water leaks, allowing growth to happen in hidden areas.

So the most important thing you can do is take action right away.

Your first course of action is to call in one of our professionals to unclog the drain line and bring your air conditioner back into good operating condition once again. There may be many reasons why the line clogged in the first place. A technician will follow the problem all the way through and ensure the air conditioner is working properly.

If you want a do-it-yourself method, there are certain things you can do the moment you discover the problem.

First, find the main drain line outside your home. Most homes have both a main and a secondary drain line. The main drain line is made of ¾ inch PVC pipe, located near ground level, extending from your home. The secondary is usually higher, and will allow water to drip out when the main line is clogged.

Using a wet/dry vac, attach the vacuum hose to the PVC pipe and create a good seal. Let the vacuum run for two to three minutes before checking. You’ll likely find dirt, dust, algae and other debris in the vacuum alongside the water that had been behind it.

This process can be messy, and may often not reach the true problems within the system. The only way to ensure the entire line is working properly is to have a professional check it out.

And annual maintenance checkup can ensure your system is working properly and in good working condition before the start of the summer season. During the maintenance we clear out the drain lines in an effort to prevent them ever getting clogged in the first place. To add extra protection, you may wish to attach a float switch that detects when water is backing up due to a clogged line and shuts of your cooling system before any real damage is done. This can prevent it from producing more water and leaking it throughout your home. We also offer year round treatments to keep the drain line free of growth that causes restrictions, ask our technicians during your maintenance visit.
