How to keep AC drain line clear?

Is there supposed to be water in the AC drip pan?

However, when it comes to your air conditioner’s drip pan, also known as the drain pan, the presence of water is perfectly normal… but only if it’s flowing out of the pan. When not taken care of promptly, a clogged drainpipe can cause serious mechanical problems for your air conditioner.

Where does condensation go from an air conditioner drain line?

Any excess condensed water is removed from the air conditioning unit through a small drain pipe that extends from the indoor air handler to outside your home. This drain pipe deposits the excess condensed water outside on the ground. Walk outside your home and look at the condensate drain line.

What does IMC 307.2.5 say about condensate drains?

How big does a condensate drain need to be?

IMC 307.2.2 tells us that an A/C condensate drain inside diameter should not be smaller than 3/4″ and should not be smaller than the drain pan outlet diameter. According to the IMC, 3/4″ is sufficient for up to 20 tons unless the drain outlet size is larger than 3/4″.

What happens when a condensate line is clogged?

When the drip pan becomes full or clogged, or the condensate line is clogged, water can spill over the drip pan’s edges, onto the floor surrounding the unit. Another sign your condensate lines may be clogged is if no moisture is exiting outdoors.

What are the requirements for air conditioning condensate drains?

Where does the condensation go in an air conditioner?

Algae or a foreign obstruction such as mulch or potting soil can plug condensation drain lines. These air-conditioning condensation drain lines (either black plastic or white plastic-looking pipes) usually drain out somewhere at the base of the house into a flower garden.

How tall does a condensing unit need to be?

Ensure the top discharge area is unrestricted for at least five (5) feet above the unit.

What should I do if my air conditioner has a condensation leak?

Either way, the line must have a down slope away from the air handler to drain properly. In either case, the condensation drain or any other thing that can cause a condensation leak should be repaired as it will cause water damage to wood and mold and mildew issues that can affect health.
