HVAC Problems: Clogged Drain Line and Overflowing Drain Pan

HVAC drain lines remove excess moisture and water that your air conditioner pulls from the air. Condensation runs through your drain line and exits your house. Condensation also accumulates when warm air passes over the evaporator coils. When everything works as it should, moisture is dispersed and evaporates. However, if water is building up and overflowing from the drain pain, this is a sign that something is wrong. The most common issue is a clogged drain line that causes water to backup into the drain pan. Clogged drain lines are common problems and can be fixed with regular maintenance and professional cleaning.

What Causes a Clogged Drain Line?

Drain lines become clogged when there is sediment or debris that gets stuck and prevents water from easily moving through. Dirt and debris can accumulate if your HVAC filters are missing or very, very dirty. Dirt and dust is small, but it can build up enough over time that it starts to restrict water flow. If left unchecked, a clogged drain line can do more than make a mess. It can also overly tax your HVAC system, making it harder to cool your home or office.

How Will I Know a Drain Line is Clogged?
