3 Reasons Why Your Air Conditioner Is Leaking Water, Stonington, Connecticut

It’s normal to see a small amount of leaking water when your air conditioner is running. However, an excessive amount can be a cause for concern and may require professional air conditioner repair services. Here are some reasons that can make your air conditioning unit drip water.

Why Your Air Conditioner Is Leaking Water

1. Dirty Air Filters

air conditioner repairWhen your air filters get obstructed or clogged by dust and dirt, they prevent airflow from reaching your evaporator coils. This problem leads to their freezing over once it gets too cold. When the frost melts, excess moisture forms and trickles into the condensate pan. The excess water in the pan results in abnormal leaking. To avoid this issue, clean your filter periodically, and change it every one to three months.

2. Clogged Drain Line

Water from your air conditioning unit passes through the drain line, or condensate line, before ending up in the drain pan. If the pipes get clogged with dirt, algae, or mold, backed-up water can leak from the unit into your home. To fix this problem, you can use a wet/dry vacuum to unclog your drain line. However, this is still best left in the hands of air conditioner repair professionals since they possess the experience and equipment that can safely suck the material blocking the pipe.

3. Low Refrigerant Level

A low refrigerant level results in low air conditioner unit pressure. Similar to a dirty filter, this can freeze your evaporator coils, and cause the drain pan to overflow once the frost melts. Some signs that you’re low on refrigerant include a bubbling or hissing noise due to a leak and a unit that doesn’t cool well. If the leak is severe, you may have to replace your whole unit. A qualified air conditioner repair technician will assess the issue and provide appropriate solutions accurately.
