If you notice that your air conditioner is leaking, the first thing you should do is turn off the unit. Doing so can help prevent damage to electrical system components as well as water damage. Moreover, there are various causes of this problem.
Read on to learn why air conditioners sometimes leak inside the house from one of the area’s best residential and commercial air conditioning companies.
Faulty or Rusted Drain Pan
Old air conditioning units at least a decade old are more likely to have a damaged or rusted drain pan. A drain pan that’s rusted through will allow water to escape and enter your home. If this is the case, you’ll need to have the part replaced.
Clogged Condensate Drain Line
The most common cause of water leaks from your AC into the house is a clogged drain line. Once the drain line is clogged with dirt, mold, sludge or dust, water will back up indoors. The drain line will then need to be unclogged by residential or commercial air conditioning contractors.
Dirty or Clogged Air Filters
Dirty air filters will disrupt airflow over the evaporator coil. When this happens, the evaporator coil will get extremely cold and may even freeze. Once this component defrosts, the melted water will be added to what’s already in the pan. The drain pan may not be able to handle the excess water, at which point a leak will occur.
Damaged Condensate Pump
Furnace and indoor AC units installed in the basement have a condensate pump that directs water outdoors. However, when the pump breaks, water will no longer be pumped outside. A damaged condensate pump will need to be repaired or replaced.
