What is an AC Drain Line?
An AC drain line is a pipe that runs from the condenser coil in the attic to the drain pan under the house. The purpose of the drain line is to remove water from the condenser coil after it has been cooled by the fan. This helps keep the system running smoothly and efficiently.
When the AC drain line gets blocked by debris, sediment, or other materials, the pressure inside the drain line builds up until it bursts. The burst causes the water to flow backward (backflow) and flood your basement.
Problems Of Having A Clogged AC Drain Line
If you have a clog in your AC drain line, you may notice some of these symptoms:
Water damage to your home - A clogged AC drain line causes water to overflow from your AC unit, which could enter your house and damages your floors, walls, ceilings, and furniture.
Flooding in your basement - A clogged AC drain line allows water to collect in your basement. Overflowing water can damage your basement floor, walls, and ceiling.
Damage to your air conditioners - The drain line is responsible for removing excess moisture from your air conditioner. If it gets too full, the drain line can burst to cause major damage to your air conditioner.
Reduced airflow - Reduced airflow means that there isn’t enough room for air to flow through your air conditioner. As a result, your cooling efficiency decreases, making you feel warmer than usual.
Increase energy bills - Having a clogged drain line increases your air conditioner’s load on the compressor. This makes your air conditioner run more often, which leads to higher electricity bills.
