If you use a central air-conditioning system to cool your home during warm temperature spells, and you noticed water is dripping from a portion of your unit, you will most likely want to take the necessary steps in repairing the problem promptly. Failing to troubleshoot the source of an air-conditioning system leak can lead to damage to other parts of your home very quickly as water starts to accumulate each time your home is cooled. Here are some of the main areas of an air-conditioning system known to leak and how to fix them effectively.
Cracked Drain Pan
Your air-conditioning system has two water-collection bins located inside to collect condensate water to be pumped outdoors. One pan is located under your unit's coils. This is usually welded into place and will need to be repaired by a specialist if leaking is occurring from this portion. Another pan is located at the bottom of the unit. This can be slid in and out by hand to remove excess water if there is a problem with the drainage system. If water is leaking from this tray, it may have a crack present within its structure. This can be easily fixed with a dab of epoxy glue or a new pan can be purchased to replace the broken one.
Clogged Drain Line
If the condensate tubing that directs water from your drain pan to the outdoors becomes clogged with debris, this will cause excessive water to collect in the drip pan under the unit. To repair this type of problem, the tubing will need to be removed from the unit. Use a wet/dry vacuum to suck any dry material out of the tubing. Afterward, rinse the tubing in a basin filled with water to help remove any embedded grime from the interior walls. Add a bit of bleach into one of the openings and let it slide through the tubing to the other side. This will remove any algae buildup from inside the tubing. Doing regular clean-outs of the tubing will help keep it from becoming clogged.
Dirty Air Filter
If you fail to change out your air conditioner's air filter on a regular basis, it will quickly become covered with a layer of dust. This accumulated debris will cause the coils of the air conditioner to become encrusted with ice when the unit is in use. This ice will then melt at times the air conditioner is not running. It is extremely important to do regular checks of the condition of the air conditioner's filter to avoid this scenario. A quick swap with a new filter will keep your machine running without unnecessary dripping incidents.
