Depending on where you live, summer temperatures can easily climb upwards of 100 degrees. When you couple this with high humidity, your air conditioner can get quite the workout trying to keep your home cool and comfortable. More than just producing cool air, however, your AC unit is also removing the moisture from your indoor air. Under regular circumstances, the water condensation collects in the condensate drip pan and eventually flows through the drain pipe and into the yard. The more humidity there is during the summer, the more condensate will form. If you notice that your drip pan has filled up, there could be a problem with your AC drain line.
As air passes over the evaporator coils in your air conditioner, it cools down and loses some humidity. The humidity left behind forms condensate on the coils and drips into the drain pan. However, water isn’t the only thing left behind on your evaporator coil in many instances. The air blowing over these coils can lead to a buildup of dirt, dust, and other substances that can create a muddy substance. As the dirt and water drip off, thicker substances can move down your drain line and cause a clog.
Like other parts of your AC system, you may need to do a little maintenance on your drain line to ensure that your system keeps running efficiently. Let’s take a look at how to clean condensate drain line.
As discussed, condensate lines commonly become clogged due to a buildup of dirt, dust, pollen, and other substances on your evaporator coils. Aside from this, however, there could be several other reasons why you may have a clogged drain line. Leaves, debris, and other objects can block your unit’s drain line over time as well. Additionally, heavy storms could bring a number of items in that will block the line. The drain line is typically a smaller pipe that can become clogged easily by any number of items. A properly working drain line is essential to your air conditioning system’s overall health and operation.
One of the biggest indicators that you have a drain line issue is the presence of standing water inside of the drain pan. As the condensate line becomes clogged, the water will begin to spill out into the drain pan. Aside from this, however, you may also notice standing water around the unit, water puddles in your drain pipe, a moldy smell, a malfunctioning AC unit, or water damage around the AC unit. You must correct the problem as soon as possible to avoid costly water damage repairs.
The good news is that cleaning and unclogging your AC drain line is an easy task. Running a thin stiff brush through the drain pipe will clean it out in the majority of cases. You could also opt to use some household chemicals to clean the inside of the PVC pipe and ensure that it is clear. A wet vacuum might be beneficial to help remove gunk from the pipe as well as clearing the water buildup from around the pipe. If you have trouble clearing the drain line, you might need to contact a qualified HVAC technician to help remedy the problem.
Your air conditioning system is a complex piece of equipment that relies on numerous components to treat and deliver comfortable air to your home properly. If your AC drain line is clogged, it could create issues for your home and AC unit. The best way to prevent any problems is to ensure that preventative maintenance is performed on your system each year.
