Summers are long and hot in Columbia, SC, so you’ll count on your air conditioning system to keep your home comfortable. The drain line is an integral part of your cooling system. Read on to discover three things you should know about your air conditioner’s drain line.

What It Looks Like and Where It Is

It’s important to know where your AC’s drain line is located and what it looks like. The line connects the AC’s indoor and outdoor units. It’s usually made of PVC pipe, but some are made of copper pipe. One end is near the bottom of the outdoor unit. The other end is near your indoor unit. The indoor portion is nearly vertical, and it has a cap for easy access.

What It Does

When the liquid refrigerant enters the indoor unit’s evaporator coils, the air handler blows warm air over the cold coil. The air gets colder, and it can’t hold as much humidity. Some of the humidity condenses into water. The water drips into the air handler’s drain pan. The drain pan empties into the drain line. The line empties the water, allowing your air conditioner to continue cooling your home.

Signs of a Problem

Drain lines are prone to clogs, explains the Department of Energy. Some signs of a clogged AC drain line include warm air blowing from your home’s vents, water leaking from the drain, a full drain pan or an air conditioner that won’t turn on. Many new air conditioning systems feature an automatic shutoff that powers off the system if the drain pan is full. Once a month, use your wet/dry vacuum to clean the drain line. Flush the line with a 10% bleach solution. As your local HVAC contractors, we repair and replace damaged drain lines.
