But there’s a difference between the plumbing in your home and your AC drain pipe. Drain clogs aren’t always an easy fix, so you may need to call in a professional. Most plumbing services can help you solve the problem without damage.

Experts in heating and plumbing services will have the right tools and training to help you. Keep reading to learn more about calling an AC service for a clogged drain pipe.

Causes of Clogs

There is one way for your AC system to develop a clog. Once there’s a clog in your AC drain pipe, you’ll notice the drip pan overflowing.

Your AC drain pipe gets clogged because of the evaporator coil. The evaporator coil carries dirt and small particles. These particles accumulate and become stuck, clogging your AC drain pipe.

Signs of a Clogged AC Drain Pipe

Standing water is one of the first signs you may notice if there’s a clog in your AC drain pipe. Standing water isn’t always an issue… but, if you notice there’s more than normal, there’s a problem. If there’s a large volume of water, you may want to call a professional for help.

You can figure out if the AC drain pipe has a clog by looking at the condensate pan. If you’re emptying the condensate pan more than you should, your unit likely has a clog somewhere down the line.


There are many things you can do to prevent your AC drain pipe from clogging. First, check your condensate pan on a regular basis. Overflowing water is one of the first signs there’s an issue with your HVAC system.

If you suspect that there’s a leak, there are ways you can clean the condensate line at home. But, it’s best to leave it up to someone who specializes in plumbing services.

Experts have the right training, and they are less likely to ruin the line if they clean it themselves. Professionals are experts and know how to unclog an AC drain pipe the right way and keep it unclogged. As a homeowner, there are some steps you can take to keep your drain unclogged.

The next step is to replace the air filters within your HVAC system. If your unit has old filters, it won’t work right and may have problems. It’s best to change the filter a few times a year… if possible.
